- TED Fellow Christina Warinner is an expert on ancient diets. So how much of the diet phad the "Paleo Diet" is based on an actual Paleolithic diet? The answer is not really any of it.
Dr. Christina Warinner has excavated around the world, from the Maya jungles of Belize to the Himalayan mountains of Nepal, and she is pioneering the biomolecular investigation of archaeological dental calculus (tartar) to study long-term trends in human health and diet. She is a 2012 TED Fellow, and her work has been featured in Wired UK, the Observer, CNN.com, Der Freitag, and Sveriges TV. She obtained her Ph.D. from Harvard University in 2010, specializing in ancient DNA analysis and paleodietary reconstruction.

The main takeaway that we should all agree on is simply this: Eat whole foods and avoid processed crap.
S
She didn't debunk shit.
Paleo is about consuming carb less than 25%, because that is the exact
amount our body can process in a day, and the remaining 60% is protein,
vitamins, fibre and so on.
Paleo advocates less carb, because in the so called 21st century, we
have diabetes and obesity on the rise. And carb is the real culprit to
that, as most of the people consume too much carb in the name of food.
Animal fat clogs insulin receptors so that carbs cannot be processed. Ketosis is a backup emergency process, but our brain's primary and preferred fuel source is glucose.
The Libertarian Vegan Lol bullshit vegan crap. ALL fat clogs insulin flow if consumed in excess over time. However moderate fat consumption does nothing to affect this. And ketosis is a NORMAL process. If you exercise regularly or are a woman that is pregnant this happens on the daily.
People are completely missing the point. She is not taking a stance on whether the modern "Paleo diet" is healthy or not. She is simply stating that it is not what people of the past would have eaten and presented evidence for it. It fact she supports the idea that past diets have much to teach us. Sometimes I think people comment on videos before actually watching it :(
Julie Wang Yes everyone is very quick to defend their viewpoint that they get triggered before actually watching the video.
Yeah, watched the video before commenting.... Her main "debunk" is that essentially Paleo is misnomer.. Something many of those authors she puts up agree on
Julie Wang no, I watched the whole thing. Also, I looked into her work and TED wasn’t the only place where she talked about it. Especially, about how she disapproves the Paleo. So, she came to the talk with her personal beliefs and vague scientific data about Paleolithic people’s usage of tools (to say the tools they found were used to grind legumes is a pretty bold statement)
Julie, you are correct. Even if Dr. Warriner stressed meat, and some Paleo Diets stress veggies - these are not the veggies the real paleolithic people would have had to eat. Our real problem today is eating too much processed food with very little fiber left in it. That's sugar, corn, soy, and wheat. She made that point. That gives us very concentrated calories with very little other good nutrients with them. And gluttony doesn't help modern man either. Our foods are 1000% more enjoyable than what men ate even 100 years ago, let alone 10,000 years ago. It's too tempting to eat nutritional bomb foods in huge quantities. I am an MD, and I run a weight loss clinic. If my patients want to eat a "Paleo Diet" that consists of a few meat/eggs/seafood daily with plenty of vegetables, that's fine. I think it sounds pretty healthy, but I'd also allow a few whole grains. But they are going to have to eat fewer calories daily if they want to lose weight.
* * * *
They are a bunch of hyper-sensitive, reactionary, meat eating, necrovores. Deep down they know they are wrong for contributing to animal misery, so they balk, and become irritated and defensive.
I'm just happy to live in a world that people have a choice over what they eat. Count your blessings!
you are awesome. Straight up.
For now.
boom!
Facts!
Not the whole world, actually most of the world can't really choose. There's still A LOT of people starving to death every year
Part of the problem relating to the criticism of the video by some, is that the title of it is misleading. At first reading the impression is that the Paleo diet is a bad diet (which is why I clicked on it). A better title would be: "What we call Paleo Diet is hardly Paleolithic at all". Or "The Modern Version of the Paleolithic Diet"
Neo-primal diet!
Cold Fury I wonder if the rest of your face is as ugly as your mouth? My point remains valid, you silly little man!
If you read my post correctly, you would have seen I "wondered" only, didn't judge. But I do acknowledge a more favourable use of language, given that there maybe ladies and children watching!
Chris Crutchley q
Just watch the video and it’s clear !!
Variety, fresh, whole foods and an important fourth point...expending the energy it took our ancestors to gather a meal before, during and after. In other words...MacDonald's should have a military style obstacle course before arriving at the take out window.
Yes, this is often overlooked. Regardless of your diet, if you sit for 16 hrs a day (8 at work 8 morning / evening), you're going to cause a lot of harm.
deep
11/10 would go to that McDonald’s
😂😂🤣🤣🤣🤣
That last sentence. Man oh man
Paleolithic people also had a feature of their diet that nobody seems to mention: food availability was spotty, not around the clock.
Not on tropical islands
That is why paleo diet was pretty much meat only diet with occasional fruit and starch
@@nile-bc9ymnope
one thing about this, whether Vegan, Paleo or Keto we all agree added sugar is the problem, lets go with that as a basis for all of us ?
Ian Rob added sugar is A problem, it's not THE problem
refined sugar, not "sugar"
What redeems unrefined sugar? Unrefined sugar to refined sugar is not like whole grain to white flour. While whole grain bread is a world apart from white bread, sweets or soda made from unrefined sugar are still loaded with nothing but ultra short chain carbs and not much else. You get plenty of kcals, a terrifying insulin response etc.
However, I think people should relax a bit and not follow any extreme dietary fad, but I still think one should be very much aware of the composition of the foods we eat. And what refined sugar consists of is really very close to unrefined sugar. Eat the whole fruit if you want any sugar, problem solved. Or even eat two Snickers per month and forgive yourself for that "sin", while having whole grain bread, brown rice, veggies and some fish the rest of the time...
boycot gugle how about processed sugar... thats what I avoid. I eat lots of fruit though.
workеd fоr me! I workеd just like I thought it would. It was eeeeаsy еnоugh and I just want others tо know when something works. Check оut it on this blоg twitter.com/6939a38171fd4db6f/status/788632172043366400 Debunking the palеo diеt Christina Warinner ТТTЕDxOU
Always great to hear an expert speak on a topic which they are well-informed and passionate about.
uh thats how ted talks work
I pretty much eat a Paleo diet. I'm so happy I saw this! This is a really good unbiased view of diet in general which really makes a lot of sense. The take home message which she preaches (to avoid processed foods) is something we can all learn from. :)
She makes some good points, and some not so good points... Like the paleo diet is aimed toward men? Not true... Also, she's pretty bias... by being a vegetarian.
Mt Vagon Yeah she is a little biased. But I guess that adds to the reason why it's interesting to me.
Eoin Kenny
It's interesting because it bias? Lol, sounds ridculous. But whatever you like man.
Well I've found it pays to be open minded about nutrition.
Eoin Kenny
So first you mistakenly feel her view is unbiased, then someone points out she is biased which you concede to, but then you say that is what you find interesting, and then you declare it pays to be open minded about nutrition...
But because she is biased... she isn't open minded.
And she is actually very biased, she perpetuates falsehoods about our biology, and frankly with her education on the matter, I would be inclined to believe she is outright lying about it, which is a bias that cannot be trusted.
As a paleo dieter myself, i wanted to hate this, but i'm really impressed. She made such good points; very well spoken also!
Hold on, hold on, watch again and pay attention to contradictions.
I was really hesitant myself, but I am loving this talk. She is so well educated in her field and the point is excellent. Everything I have asked myself about the paleo diet, you know, how can we KNOW? Great talk!
Reem Sulaiman
This was an eye-opening talk for me, too. She’s quite a good presenter.
@@cellardoor199991 You are wrong. She said humans don't have carnassial teeth, which is actually very true.
@@cellardoor199991 nope. youre wrong, we dont.
Wow, I had no idea so many fruit and vegetable species are bio-engineered by humans. Pretty cool to find out about this.
GMO foods has codes starting with the number 4.. example 4011 is banana
Yeah it makes me not want to eat them but I don't know what else to eat
@@edwardrook8146 well... technically, plain ol' horticulture IS genetic engineering. You just did it selectively by breeding/crossbreeding the examples you found with desireable traits. A couple centuries of that, and you go from the nightmare that WAS a watermelon... to something far closer to what we have today. My point is, selective breeding over millenia has led to mostly more abundant and nutrient-rich foods, and I wouldn't consider a specific cultivar - far removed from its original form - to automatically be a *bad* thing. Most of the time, it's better (for us) than before.
@@d112cons no the toxins are pretty healthy actually
@@lararnunes6253 I thought a tag starting with 4 meant sprayed with pesticides, or non organic which leaves a lot open; chances are it could be gmo too I’d imagine.The point of gmo’s are to make plants immune to pesticides like glyphosate (round up). Me I eat organic and mostly veg, then fruit..a little meat and dairy. Simple-no processed sugars, or too much any other sugar. Less processed oils..Fruit has fiber to slow digestion of it’s natural sugar..Your taste buds can actually change without cane and processed sugar so it tastes not so good awhile after abstaining. A mention..So many diets can cause stress and eating disorders. Watch out for diet gurus..alot of money in it for them, and not clear, or even contradictory ‘research’ touted.
She put on a good presentation. Makes me think of a friend who had a craving for awhile for lemons who said..I think I needed more vitamin c. Me,I related-have craving for onions with everything..so, take away the cane sugar and possibly cravings are a good thing and can lead to truly instinctual eating, and trusting what your body needs..Maybe that’s all we need and is good enough! Also, fiber can feed good bacteria in gut..lots of research coming up on that nowadays. No doubt someone will write a book saying we need MOSTLY fiber..ha!
Enjoyed this talk. As she clearly shows, paleo humans were not the carnivores that some people want to claim (the teeth and lack of being able to make our own vitamin C are great evidence). I've studied diet and nutrition (non-professionally) for decades. Learned that protein intake has a very wide span of what is healthy, although older folks do need more. There are lots of ways to get it. I'm not anti-meat, but I do think it's healthier to eat smaller amounts of meat. And it's much better for the planet. It takes a tremendous amount of water, for one, to make a pound of cow. As Michael Palin says: Eat (real) food, mostly plants, not too much.
We don’t need the teeth, we have thumbs and big brains… my ancestors crafted and used spears.
And meat contains vitamin c.
Geee wonder how those Eskimo folks have been able to live for 100,000 of thousands of years
Wow! So much knowledge, so good to hear it from an expert, especially one who seems more interested in health and facts than selling anything.
This is an interesting presentation and she is concise in her delivery.
Just a detail on the talk's title. I really dislike the word debunk. The word discourages those that subscribe to the topic to watch or listen. So we need to abandon the word debunked, debunking and debunk as well as exposed and replace them with; challenged, disputed. these words keep the debate going and attract everyone to give a listen.
As of now when I try and share this to my paleo friends they won't give it a chance because of the title being aggressive.
it's not about being PC. It is important to choose your words wisely when you are trying to spread a message. If your language turns people off, instead of inspire them, then your message falls dead in the water. There is nothing "politically correct" about choosing between "challenged" and "debunked". Neither word is presumed offensive.
O.P. was just suggesting that the message would reach a wider audience with a small title change.
@Ella Blun All she basically proved is that the recently popular "paleo" diet is NOT what our ancestors ate (because it would have been impossible).Thousands of years ago, you could not have blueberries and avocados on the same plate because they naturally grow in completely different parts of the world, and transportation had not advanced far enough. You missed her entire point.
Ella Blun I don’t think she was trying to say the paleo diet was bad. She was saying that it’s just not paleo. It should be called something else. That doesn’t mean she thinks that the paleo diet is unhealthy or that you shouldn’t do it. It’s just unfortunately named badly. It misleads people. But she doesn’t ever say it’s a bad choice of diet. She was debunking the idea that paleo people ate this kind of diet - they didn’t. But that doesn’t mean we shouldn’t.
Wow... You were so excited throughout. And thank you for such precious convincing information.
This is a great topic to cover. Please post more like this in the future. Excellent!!!
OK this was one of my favorite TED talks of all time. The science was so interesting and I learned so much. I loved her presentation! Go science!
clearly u haven't seen many ted talks
I can't tell if you are being sarcastic or not. Are you winking with your left eye or your right? (GotG joke, ftw)
You need to read more. You will realize science vs Fantasy.
Holy crap, I always thought the seed in apricots looked like almonds. That's amazing :p
Amazing talk and well worth watching twice! Delivered in such an eloquent and interesting way.
Except not really. This talk is full of BS and pseudoscience.
This is a glorious wonderful video of talking about the best real foods for our lives.
God bless us all,
Gustavo Ceja
The purpose of the video is not to debunk whether Paleo is healthy, but to debunk the claim that Paleo is based on sound archaeological and anthropological evidence.
The thesis of the video, and the message I am taking home, is that the Paleo diet is based more on philosophy and observations about nutrition science than it is on archaeology. While she makes a few small observations about healthy eating, the focus of the video is not about whether or not Paleo is healthy. It is about archaeology and anthropology.
She observes that the foods suggested in Paleo literature are quite different from foods available in the Paleolithic. She provides examples. The breeding of broccoli, almonds, carrots, and apricots, which either did not exist or were somewhat toxic during the Paleolithic, are widely accepted by proponents of Paleo as healthy. Precious little that can be found in any grocery store that resembles their paleolithic counterparts. So different are some paleolithic foods from their modern-day counterparts, she observes, that "many people in this room would not recognize it as edible."
I especially appreciated her observations about how the philosophy of Paleo can, in fact, lead to healthy food choices. She argues that a paleolithic man or woman must eat more than eight feet of sugar cane to ingest the same amount of sugar in one large soda. This explains why there is evidence that Paleo dieters eat fewer calories while feeling as full as those following some other diets.
Finally, the voice of reason. Thank you, Keith, for pulling it all back together. I am a practicing dietitian and hear all about many different diets. Many that I personally either do not agree with and/or know are scientifically baloney. I do not tell patients not to follow something unless I know it is harmful. The Paleo Diet, Atkins Diet, South Beach Diet, Zone Diet, et al. People become very attached, especially if they have had success or at least no harmful results. The bottom line is recognize that "the diet" is a product to be sold in the form of a book like any other product. Rarely do facts seem to matter--whether it seems reasonable or even too good to be true. I say pick an eating plan that works for you and does not cause further harm and stick to it. Stop defending it to others like religious zealots. One way is no more "right" than another. The quickness to respond with how wrong she is is astonishing. Does anyone have her scientific background or even care or respect her depth of knowledge? What has happened to critical thinking? Keith, thanks again for your balanced response.

*_"The quickness to respond with how wrong she is is astonishing. "_*
This video was posted 8 months ago... what is the appropriate time to wait before responding?
@@rdabq5991 LOL exact what happened with critical thinking; major problem with humanity!
Literally no one eats "Paleo" thinking that's really how our ancestors ate, NO ONE; the point is to eat whole, unprocessed food.
NO it explains that no historic ancestor in their right mind would have attempted to eat even one eight foot cane of sugar. But most folks I know have no problem guzzling down that large soda. It does not explain that paleo dieters eat fewer calories while feeling full.
The paleo diet is a logical framework which you should apply to your basic nutritional principles. It is not meant to be a historical re-enactment. If you read any of the books she showed in the beginning they all make the points she makes about how impossible it is to emulate a paleolithic diet.
Her dietary recommendations at the end of the presentation are the exact recommendations and arguing points of the paleo diet....
See, here's my question: which Paleo diet? Is there basically just one? Or, has it become the latest and greatest marketing term from which everyone's trying to cash in on; selling their version of a diet book? I don't know, there are many basic common sense concepts in Paleo, but it seems a little too much like the soup du jour to me.
My most heartfelt compliments to this scientist. Her vibrant exposition got all of my alert attention from head to tail ; good job, and thank you very much for the enlightenment
This was so interesting and I really enjoyed the historical aspect of the different foods. People are commenting about taking offense to this presentation when in reality she is just stating the differences between the historically accurate caveman diet vs. the 21st-century caveman diet. So interesting!
But nobody mentions that cavemen didn't live past 30, so...
@@windsofmarchjourneyperrytr2823 Been a witness ?
Just one observation: There are NO 21st century cavemen... wannabes, lots for sure, but not the genuine article. Going to the gym, pumping iron does not equate "cave man", just for an example... but it was fun to read for sure!
My grandmother is turning 105 in couple of months. She has never been a vegetarian either paleoterian. She has been eating just about everything but small amount of food. Meat, fish, whole grains, nuts, coffee, wine, lots of vegetables and fruits. But she doesn't eat any processed food mostly homemade and locally provided foods.
She is a very very positive and funny person. Easily let go of the past.
I truly believe that eating whole food and positive attitude is the key for her longevity.
It amazes me how many people on this thread think they know more than a person who is an expert in their field and has spent their life, so far, researching this topic!
An interesting, philosophical side-note: when you declare yourself to be an expert in any given topic, the more you close yourself off from learning more on said topic. Food for thought.
So we must believe her only cuz she say so...
Its amazing that you believe she debunked the paleo diet.
+Rae The topic includes the diet so it hasnt been around her whole life. anyway we all know the paleo diet is just the atkins diet with atkins crossed out.
+Fate it is a strong tendency but not an inevitability. the more you know the less you understand....unless you understand and are just curious
Umm... she's not a paleontologist.
I would have loved to hear her speak about how ancient populations made (pseudo)grains more nutritional and easier to digest by soaking/sprouting/fermenting them. This happened with quinoa, for example.
exactly!!
Balanced, insightful, and loaded with real science thanks for the wonderful lecture warm regards Dr Prashant Murugkar
except that she proved why ppl should prioritize meat
People ate WHATEVER they could get their hands on! Early humans lived virtually all over the globe, including the arctic, tropical rainforest and the deserts. Food intake depended on each geographic location. We are omnivores! We were clearly meant to eat whatever the hell we could find. Also as far as digestive tract, our digestive tract is longer than carnivores, but much shorter than herbivores.
There's no one size fits all way that people were "meant" to eat. I'm tired of people saying "all people were meant to eat _________." Our ancestors didn't all eat the same diet. You think early people living in the arctic had the same foods as early people living in tropical areas? Early people lived EVERYWHERE and that we KNOW based on archaeological finds. So if we know early people existed virtually everywhere, why then try to say they all ate the same way? It defies logic. Some of our ancestors obviously ate meat. Some of our ancestors obviously ate plants only. Others had access to fish, while some didn't. My point is early humans didn't make a conscious decision of what to eat, they ate what was in their immediate surrounding. It's not like they could drive or take a train to get food elsewhere or fly / import food in like we do today. They had to walk to get food so they couldn't go very far. After a while they rode horses and donkeys once civilization picked up. But the earliest humans were on foot. They ate whatever the hell was in a close radius. Period.
We were meant to sustain ourselves on whatever was naturally available, which makes us omnivorous. And that didn't include all this processed crap and GMO garbage. But, thank you to small, local, family owned farmers who provide a wide variety of food at Farmer's Markets, and livestock such as grass fed and reared Bison etc. Eat a wide variety of nutritious foods and you'll live a long healthy live, don't get hung up on the meat or no meat issue.
This was awesome and very scientific. Thank you! ❤️
So incredibly interesting! Thank you for your research !!
Thank you for the informative talk. Regardless of whether the title was a bit misleading, it contained interesting info on the foods of our ancestors and how we can apply some of this knowledge to our lives now.
And how was the title misleading (to you)? I think it hit the nail on the head.
yeah, what was that title about? should be "Optimized Paleo Diet"
The title explained exactly what the talk was about. Smh
Apparently some of you vegans are very ignorant of the devastation cause by agriculture and that agriculture feeds the evil of CAFOs, that allows you to eat a environmentally unsound diet. You debate from a state of ignorant bliss, high and mighty about how morally superior you are for not eating meat. There is no saving grace for your ignorance, as we turn to more soy and grains that cause desertification. There is hope, as some growers return to traditionally raising of animals and of land and have turn some acres of land that was dead into thriving living things again.
That cannot be done with agriculture or plants alone, this is a symbiotic relationship between people, animals, plants and life (i.e. microorganisms, fungi, nutrients) maybe you should pick up a book about the detrimental effects of our current agricultural system which is Essentially required to feed everyone. I particularly enjoyed How cows can save earth, can't remember the author. I also would ask that you consider, if we all turned to veganism, all those animals we currently breed to eat would die because they is no reason to breed them. If they breed on there own they would die from the lack of food and from an increase in preditors (more herbivores=more carnivores), and possibly from not being adapted to live without assistance (shelter for instance). Returning once to the immense desertification that is steadily increaseing, with desertification and invasive agriculture the amount of methane that would emerge would and is catastrophic. It's really like a slow Hollywood disaster movie.
Allan Savory has a pretty good talk on this very topic. He moves huge herds of livestock around to mimic nature and reverse desertification and climate change.
Watch cowspiracy.
liapeace1 Ok, watched it.
how do you suppose those animals you eat are sustained? Do they live in a dessert and require no maintenance, no food, no water.. are they bretharians according to you or something? It takes so much more resources to feed those animals for several years until they're old enough to be your "dinner".
3:18 "Humans have no known anatomical, physiological or genetic adaptations to meat consumption."
Anatomical adaptations: Prof. Warinner Makes the point we do not have adaptations typical of most carnivores, like specific dentition (I’ll get to the digestive tract in a moment). I find this a bit problematic, as our meat eating appears to have developed in lock-step with the technologies of tool use and fire. Richard Wrangham of Harvard makes the point humans “pre-digest” their food outside the body by cooking, cutting, grinding, and processing. Humans have no “anatomical adaptations” to the cold (generally…there is a tendency for cold living people to become more barrel chested, shorter limbed, thus creating less surface area and conserving heat…Neanderthals showed this same tendency) yet we have populated areas of extreme cold by the use of technology: clothing manufacture, insulated structures to live in and again, fire use. The omission on the part of Prof. Warinner on this point of technology driving various aspects of human evolution is really troubling for me. Clearly she must be aware of this, but for some reason ignores this point entirely.
Absolutely right. We also have no anatomical adaptations for eating grains, try eating wheat or barley without cooking it if you don't believe me. You can however eat raw meat if you're badass enough. Check Laurens van der Posts experiences with the Bushmen. Although fairly carnivorous, I've never followed a paleo diet or any other "fad" diet. My understanding is that they don't promote exclusive meat eating and the idea that say we should all live on red meat is a straw man.
@h. s Veganism has only existed for a little over 50 years. Meanwhile, there have been societies around the world that ate/eat a meat/animal products only diet. Which one is a fad again?
@@xzodiayinzero5929 Both. People throughout history ate anything that they could. Copralites (fossilized poop) show that in some areas pre-civilization peoples were almost vegetarian, in other areas they were almost carnivorous, in other places they ate just seafood and sea plants. We're omnivores, we eat everything.
@@cuscof2 You don't understand my comment. I'm not talking about the nomadic hunter-gatherers that were forced to consume starchy plants when they had an unsuccessful hunt. I mean actual developed cultures where animal products were virtually the only food consumed. Even when looking at coprolites, the ones that lean towards vegetarianism don't show the full story. Typically, paleolithic people only ate plant foods as a secondary option when they couldn't get meat. Those specimen must have been during a time when there was a period of unsuccessful hunts.
Omnivore doesn't mean anything.
@@xzodiayinzero5929 **Forced** to consume starchy foods? We've been eating starchy foods so long that human saliva has evolved to pre-digest it before we even swallow. Deliberately cooked tubers have been found in hearths in South Africa from over a million years ago.
"animal products were virtually the only food consumed"
And what did they do when everyone started dying of scurvy? Humans can't produce vitamin C, we have to get it from plants.
"animal products were virtually the only food consumed"
And you know this, how? I'm much more likely to take the word of professional biologists, archaeologists and paleontologists than "random Internet guy", and they're unanimous on the matter: humans are omnivores.
The strange thing about all of this (what-to-eat business), is that we actually have to have some experts tell us what to eat and why.
How else do you learn anything in life? Its either do the experiments/research hands on yourself or listen to the people that have already done it. Same goes for nearly everything else. Such as growing up, you can learn your lessons the hard way or listen to your parents that have already been through it.(sorry for anyone who didnt have parents or someome to raise them with love) Of corse, the best method is somewhere in between, IMO. Take into consideration what experienced people speak and also what you have found in your own experiences along the way.
Why does she continually say the the Paleo diet is mostly read meat? The paleo diet is mostly vegetables with 3 to 5 ounces of protein three times a day. On a plate, most of it should be vegetables.
It's called strawman argument.
I agree. Paleo is not about meat.
Yeah, the only benefits you're getting from that is from the vegetables. The meat is just adding calories and slower digestion.
Maybe she was thinking Keto diet and doesn’t realize the difference. A lot of advertising for paleo looks really keto, so you can see how that could confuse people.
Red... lol not read..
Not really a debunk, very informative but sounds like someone who supports the same basic findings. The problem with 'Paleo' is it is idea easily misunderstood. In essence it uses an evolutionary perspective to inspire a healthy way of living in the modern world.
This video was a real eye-opener in terms of the foods that we do eat, it seems like most have been modified in some way through human technologies. Time to get back to the basics
Errm, the 'basics' are extinct, so.....
Amazing. In the last few months I’ve been trying to figure out what to choose from- paleo, keto or SOS. I know what I must do now!
Thank you Christina Warinner, and thank you Tedx. Awesome info!
Screw the paleo stuff, I just learned so much about the fruits and vegetables that we eat. Most of it (as we know it ) doesn't even exist in the wild. ..crazy!
It's poison
But bread and whole grains cereals were found in the wild right??
Are you pro or anti paleo / keto?
yes, in wild vegans gonna die. Only animal food there.
@@magdal3nam.353 TRUUEEEE!!!! That is why the ancient Egyptians invented the agricultural and irrigation system to water their precious Lion chops and T-Bones buried in the soil! Also, that is why there are no such things as Vegetarian Animals and every single animal relies on killing each other meat.
Oh and also, that is why "seeds" and "Fruit", yeah don't actually exist in the wild, it's not like you can just go out and Gather some berries or find some nuts, because they don't exist! It's FAKE NEWS!!!!!
She doesn't debunk Paleo here, she supports it, at least Dr. Cordain's version, though apparently unknowingly. Did you notice she stated early on that Paleo means 10,000 or more years ago (pre-agriculture), then gave her own debunking "paleo" example from 7000 years ago in Mexico? That's about 2000 years AFTER native Americans started farming maize and squash! (read "1491" by Charles C. Mann - he documents this very well, great book!). Then she goes off about how our cultivated plants have changed (duh, this is not news to the Paleo community). Then she concludes with 3 pieces of dietary advice that are actually main tenants of Dr. Cordain's book The Paleo Diet! 1) Diversity is key - we eat too much wheat, corn, and soy (all excluded from The Paleo Diet and replaced with a large variety of fruit and vegetables), 2) Eat fresh foods, in season (fresh fruit and vegetables are the base of The Paleo Diet - Paleo and Carnivore diets are VERY different - she confuses them), and 3) Eat whole foods - minimize added sugar and avoid processed foods. If she would just add 4) Eat fish and only lean, unprocessed meats, and 5) Avoid salt, she would actually be 100% recommending The Paleo Diet per Dr. Cordain! That IS The Paleo Diet! It's allowed me to drop 50 lbs, several years out, without missing a meal or EVER feeling hungry. I'm mid 50's, 5'11" at 170 lbs, a weight I haven't seen since my early 20's. We have an obesity epidemic in the western world that's not being helped by an anthropologist bad-mouthing a great way to combat it - a way of eating she doesn't realize she actually supports!
You didn't understand the message of the video...did you even watch it all? She's saying the fad diet capitalizes on anthropological facts that are actually not correct.
I read Primal Blueprint and it was not "meat heavy." In fact, if I remember correctly 80 percent of a plate should be unprocessed plants such as vegetables and fruits. Nuts and seeds are snacks and meats would be lean and in small portions because meat more than likely was not consumed daily in paleolithic times, but as she stated regionally it could be different. She mentions diversity and fresh and Primal Blueprint was saying the same thing. I have eaten this way before, and it seemed like just clean eating. I felt great, became healthier and did not have calorie bombs from processed foods. Everyone is different but I found too many grains gives me heartburn. When I removed grains, it went away within two weeks. Diverse and fresh produce, edible without cooking, and lean meats in small portions with occasional cooked legumes and tubers proved to be the healthiest diet for me. Eating unprocessed meals, I never had the post meal "Food coma," and had much steadier energy throughout the day and very restful sleep.
I love this ted talk! Very informative. I have realized that the best way to do a diet is to study everything relating to it and then tailor one that fits ME!!
She states that in arctic and subarctic zones "sure, people would have eaten a lot of meat". Incorrect. They ate a lot of fat, just like Native Americans' traditional diet during winter. Meat is too energy intensive to digest when it is extremely cold, and like polar bears (whose digestive tract is very similar to ours), meat is abandoned and fat is consumed. Otherwise they'd freeze to death. During winter, wrapped blocks of 20% bison meat / 80% bison fat were consumed as the primary source of nutrition for many Native American cultures.
Stepping out of the lab, here's what Native Americans in the Southwest ate before adulteration of food supply by invading europeans. The CHART on fats is of particular interest, refuting the speak's argument. This stuff isn't rocket science. There are many, many field studies on aboriginals around the world today and what they eat. For instance, in Australia, field studies measured, across 3 months, an animal/insect/reptile protein source daily content ranging from 30% to 80%. www.westonaprice.org/health-topics/guts-and-grease-the-diet-of-native-americans/
The speaker makes many excellent points, some about Palio Diets (another fad) that are self-evident. The end of the lecture brings her best observation to light. However, some arguments aren't air-tight. She compares our digestive capacity, dentation and physiology to that of ungulates. Any archeologist in the field can immediately assign a skeleton to either Neolithic or Paleolithic eras by the condition of teeth, the shape of a skull and by diseases like tuberculosis that leave scars on bones. Nice young lady. I certainly do not advocate a mythical "Palio Diet". Balance and moderation are the keys.
Tomas Nofziger TOo bad some of yours leaks too ;), We simply aren't designed to eat meat, we have no carnassials and our digestive track is too long ( for meat!), and we don't produce our own Vitamin C like carnivores do.
Did you miss those points , making it abundantly clear we aren't designed for meat ? That was right up front. Yes , most ungulates were mainly herbivores, so was that your comment to say we aren't ? Incorrect, we certainly are, and the sooner we get to a vegan diet the sooner we'll all be much more healthy, save our global warming ridden planet and fix hunger ( most food feeds big agro).
Least of all the moral side of this is SO clear. Nuff said on that point, which should be clear to anyone ( not saying you) not a troll or whom has done sufficient research to understand the underlying principles.
Meat has been proven over an over again to be bad for us, same goes for milk. Its not designed for us, period.

“The association between consumption of red and processed meats and cancer, particularly colorectal cancer, is very consistent,” says Marji McCullough, PhD, a nutritional epidemiologist with the American Cancer Society.
" After a systemic review of scientific studies, an expert panel of the World Cancer Research Fund and the American Institute for Cancer Research concluded in 2007 that “red or processed meats are convincing or probable sources of some cancers.” Their report says evidence is convincing for a link between red meat, processed meat, and colorectal cancer, and limited but suggestive for links to lung, esophageal, stomach, pancreatic, and endometrial cancers.
Rashmi Sinha, PhD, the lead author of the National Cancer Institute study, points to a large number of studies that link red meat consumption with chronic diseases. "

***** The vision you have for yourself is excellent. I'm not trying to change your mind. Paleolithic and contemporary aboriginal humans mostly eat organ meats, not the muscle cuts you see today in supermarkets and in restaurants. Personally, I'm not a meat eater. Yet the plants of our ancestors, including their flowers, fruits and seeds, were bitter and often toxic from lectins. WIld grains are not consumed by any contemporary aboriginal peoples.
Tomas Nofziger I really enjoyed her talk, it is good to hear other people's point of view. However, I was surprised about her comment about vitamin C. I think raw meat and fish has plenty of vitamin C. The Inuit don't get scurvy, do they?
I do paleo for last 2.5 years and I dont want to stop. My body likes it so much!
Christina Warinner thank you, you gave me answers on a few very important questions about diet and health that I could not find answer on for years.
Fascinating. I wish it was a wbhole hour long lecture!
Excellent talk! An extremely brilliant scientist and I am positive that this is not the last time that we will have the pleasure to hear this woman talk. She nailed it!
I really don't understand the dislikes for this video! This was one of the most interesting tedx talks I've ever watched!
I really don’t understand the likes for this video!
But definitely a great ted one of my favorites
Because Tedx invites speakers on who are pro-vegan (the starvation diet) and anti-paleo (the diet of optimal health). Why don't they get anti-vegan or pro-paleo/low-carb speakers? There's an agenda here.
It's because she thinks she's debunking a diet when everything she says is in support of it, so it's an absurd and idiotic premise. The cause behind it- she cares more about the name than the diet itself and spends an entire Ted talk taking the name way too seriously. It's like criticizing the color of your opponent's tie in a debate. It's irrelevant and pointless!
I feel that the fact that humans have longer intestines than a strict carnivore does not necessarily mean that we should be the opposite, vegetarian. It simply means we're equipped to eat vegetables. We're obviously equipped in different ways to eat meat as well.
Paleo diet worked for me, I lost 5kg ( what I needed) and didn’t put on weight afterwards! It is working to maintain my weight and I feel much better health wise. My skin and my hair look great!

She seems to be taking the very superficial aspects of the Paleo Diet, especially those aspects which represent marketing to consumers targeting Paleo dieters, and and comparing that information rather than comparing any real researched per reviewed studies and papers.
When something fails on a broad level, you don't need to go deeper. Her premise is that the Paleo diet does not represent what real paleolithic people ate. She doesn't need to know anything more than the superficial aspects of the diet to prove that.
I'm really confused about what you guys were expecting. It says right in the description what she was setting out to prove. She makes no claims about the efficacy of the diet. She only disproves the logic behind it.
ZipplyZane
Yeh this superficial stuff isn't a real and true representation of what the Paleo Diet is. Eating heaps and heaps of meat - that isn't the Paleo Diet I know. Our ancestors ate meat regularly, to be sure, but probably not everyday. I'm pretty sure the foraging for berries, nuts, yams, etc was far more productive than the hunting. Sometimes the hunters come back empty handed, but not the foragers. These were the every day foods. Grains and legumes, however, were certainly not an every day food as in modern diets.
Starchy grains and starchy legumes do make me sick - I have a nasty immune disease called Ankylosing Spondylitis. The reaction to eating these is surprisingly fast. I can't blame people if they don't believe me.. I had heard people say this about my condition and didn't believe it for years. I thought they were fools. BUT the real reason I can digest these starchy grains and legumes is damage to my gut flora leading to improper fermentation. This is primarily due, I think, to some aspect of our modern lives. It could be preservatives, it could be antibiotics, or lack of contact with dirt from our modern cleanliness habits.. it could be all the above...
ZipplyZane There is the issue to your confusion, go deeper into what exactly? This Paleo Diet is a manufactured diet by publication companies that want books on the shelves that sell like the Scarsdale diet, or South Beach diet or Vegan diets books which are all the rage. If you rare tailoring your criticism solely on the media market, you really have not explained or countered any peer reviewed research used to promote any vegetarian, vegan, Paleo, low carb or whatever group who base their claims to promote their diets through real research.
People denying the Paleo diet are denying common sense. The logic of the diet centers on evolution. Humanity existed for 3 million years. The biggest evolution was cooking meat that led to brain evolution. Grains, legumes and dairy that came from settlement is 10,000-40,000 years ago. The argument is that 10,000-40,000 years is enough time to develop SOME tolerance to these foods through evolution. But evolution has not completely removed the digestive problems that these foods have caused.
People today act like we've evolved into a completely different species and are not governed by the same laws that governed cave men.
Her assertions rely on evolutionary assumptions that have been demonstrated unprovable. The trophic hierarchy is simply false according to the data. She even points out the problems with using it. Concerning the paleolithic ecosystems--she flat tells us we know "too little" about it, and then moves directly from this assertion to saying "its false that they didn't eat grains." Again, any concern for the "paleolithic peoples" assumes evolutionary mentality that they are an inferior less evolved peoples and the archaeology simply does not back this up. The most ancient remains have demonstrated their more advanced levels than us in every way--they were larger, they were faster, smarter, and stronger. We have devolved because of the degradation of the worlds ecological conditions: degrading magnetic field, atmospheric pressure, oxygen content, etc.
Although the issue about the cholesterol has been researched and documented as a medical industry driven hoax. There have been plenty of people in other countries who have had cholesterol levels as high as 600--yes that is NOT a typo--600 level and have been perfectly healthy. The entire cell membrane constituting the human body is 80% cholesterol. This chemical is the healing chemical in the body--is heals injury. This is why the cholesterol is found in the arteries--because the sodium we consume so much of is damaging our arteries and the body sends cholesterol to heal it. But how much sodium do we consume? Typically 300-400% or more of what we should be and this puts the body into overdrive to heal the damage done, and what happens? the Cholesterol gets backed up in our arteries. What's the solution? Don't make the body send it in the first place, so lower your sodium intake and enjoy your eggs.
JR Woods MA MDiv Peer reviewed evidence to back up your claims ??? Are you telling us, that doctors everywhere telling us to keep our cholesterol levels in check , are quacks and 'failed' the MD final tests about sodium ? Show us the evidence, because I find it hard to believe a entire industry has been made on false claims.
***** what industry are you referring to? If their is a paleo industry its very small haha and what doctors telling you to keep cholesterol are telling you to do via paleo? First of all, your typical medical doctor receives very very minimal nutritional education so i seriously doubt doctors are saying "hey… to lower your cholesterol I want you to go on this paleo diet" no… they are saying "here are 5 different medications that will all give you worsened diseases, oh an cancer to, come back and ill give you 10 more medications for that" Doctors are pressured by drug companies to give drugs… they are MEDICAL doctors.. not nutritionists
Andy Pittman That's so true I have to show my doctor how to eat correctly. I don't take pill for anything.
Andy Pittman none of that matters..choleseterol must be kept low, im not one of those nutty sketpics unlike you.
Unless you have a peer reviewed article about your claims,,then im NOT interested. Simple.
fact checks matter.
Plant based diets are proven to keep us all much healthier, and more moral. THe ethics of most all religions, is 'do as though wish, though it harm none'. Im not making that up. So what does that say about some humans, that think its ok to eat meat, and the suffering that goes with it ? Desensitized at the very least, and horribly apathetic on the other side to the point about not caring.
That's not human(e). We can all do better, and that's its so easy, and better for our health now, and feeds more people therefore reducing hunger and stops global warming, there is no longer any excuses not to ;)
Great points made by a knowledgeable, and potent speaker.
Actually her three main takeaway points (variety, fresh, and whole foods) are also cornerstones of the paleo diet plans that I have read. No one is pretending we are eating from the exact same food options they had 10,000 years ago.
The thing is she isn't saying paleo is unhealthy. her main criticism is that to name a diet paleo when in reality it has little to do with the palaeolithic times and to sell the idea of it isn't honest. she was mainly informing on the archeology aspect of it. Another main takeaway is that grains and legumes were eaten by past humans and to exclude them from your diet without any reason is just redundant.
@@uhgood814 we dont need grains and legumes at all, and if you wanna eat them without most of its pernicious stuff you gotta soak, sprout, ferment them and go with whole versions..
@@wallacesousuke1433 i didn't say we needed them to survive. I said there isn't a reason to remove them from our diet other than wanting to do it.
@@uhgood814 :
“Whole “ food is rhetorical. It Does not mean anything. Eating a whole poison ivy leaf does not make it less poisonous.
A great perspective on paleolithic diets and why their name may be a misnomer, Being a physician I see first hand the benefits of a diet high in vegetables and meats and low in carbohydrate (especially refined ones). Whether cavemen ate grains doesn't matter as much as knowing that a diet high in grains is not a healthy diet and a diet of mostly vegetables and meats (add your marrow and organ meat if you choose) leads to lower cholesterol, less obesity, less prostate cancer, decreased severity of autism, decrease risk of Parkinson's, lower blood pressure, less allergies, the list goes on. We are continuing to find the harmful effects of the modern western diet and understand the diseases of affluence. Refined grains are a major health hazzard.
Seriously?!? this is your take on this informative presentation? Wow, you have quite the confirmation bias based on your opinion. Here is a scientist stating unrefined diversity is historically supported and you marginalize it with your egotistical derived opinion. This is an endemic cultural problem and a reckless one when people of stature (Like you) meddle.
brolan5150 The basic diet is to eat anything that can be eaten raw (except meat, because of cross contamination, but if it came direct from an animal it technically can be) I have 2 questions, and maybe you can answer them brolan5150, why is the question of which digestive system is closest to humans not being addressed here. the only thing she covers is longer tracks for food to stay longer. Cows and most animals that eat grains and plants only have 4 stomachs!!! We have only one, like all other carnivores. That is a huge evolutionary truth! Second, the essential vitamin B12. It is only found in meat. It is not found in any plant form. Now, how did we evolve if we did not eat meat?
Marvin O The ruminant digestive system is drastically different from the carnivore system. Humans clearly have some omnivore adaptations (amylase released from the salivary glands for example), but by and large the human digestive system does not break down cellulose. Cows, as you mentioned, have four stomachs and they are teeming with specific bacteria that ferment plant matter which breaks down cellulose. Human gut length is longer than most carnivores, but nowhere close to a cow. The human gut microbiome can ferment some plant matter to an extent but nothing like a cow, sheep, goat, or horse. (which is why it's good to include veggies in your meals, not for the nutrients but to feed your good bacteria which we are learning play all sorts of roles in our health). Check out the 'expensive tissue hypothesis' which claims we became human because we ate meat (it fueled our brain growth).
Daniil Pintjuk Thanks for the big words used, made me learn having to research them. Fruits & Honey have carbs too, so the fact that you follow a "Paleo" diet does not mean you are abstaining yourself from carbs. The idea here is that you will eat everything that can be eaten raw, you may choose to cook it of course. Your "gut micro-flora" will feed off the unprocessed carbs you ingest from natural sources.
What about whole grains like oatmeal and quinoa?
This lecture was so useful. I finally know how to pronounce agave.
lol
if this diet is so right and drugs so wrong explain the rolling stones 70 plus years old and going strong.
No one is talking about diets in this comment thread...
Marc Montti rip to ur arteries
Paleo is about consuming carb less than 25%, because that is the exact
amount our body can process in a day, and the remaining 60% is protein,
vitamins, fibre and so on.
Paleo advocates less carb, because in the so called 21st century, we
have diabetes and obesity on the rise. And carb is the real culprit to
that, as most of the people consume too much carb in the name of food.
Thank you, Mare. I always appreciate your wisdom
She's an excellent presenter.
Okay, just a few seconds, and based on the description, she's not really debunking the paleo diet's efficacy, just that it doesn't actually represent "paleo".
If this is wrong, and she does argue against the diet's efficacy, could someone reply to this comment and then I'll watch the video.
Yeah she is basically saying that the "Paleo Diet" as it's advertised is anything but a paleolithic diet. Having said that, the foods that the "Paleo Diet" advocate are good for you if you eat them as whole foods and not processed. She also stressed that there is NO ONE GOOD DIET that's above the rest. The key is diversity, and avoid processed versions of food. So basically, eat healthy... lol.
she did mention that today's meat is not lean like meat was then
***** And fat found in most meats today is most certainly not that deep yellow fat either. So before you go telling people how good fat is, best take a look at that fat. Won't take long for you to see that the lipid balance in the fat is completely different. It's not even close to the same product.
DW alberta Did you see why those "experts" ranked it last?
"But U.S. News & World Report's experts said the Paleo Diet was too restrictive for most people to follow long term, and that it limited some essential nutrients. They also cited a lack of research proving the Paleo Diet's cardiovascular health and weight loss benefits in their ranking."
So lets see, too restrictive means it is hard to find good pasture raised meats, and NEVER EVER disrespect king corn. In other words NEVER cross big ag, they are 10 times more powerful than big oil. Limited essential nutrients? Really? I'd like to see that one. Complete BS. I guess since whole foods are not "fortified with 8 essential vitamins" that means that would disrespect big pharma too! LOLZ And lastly since when is absence of evidence the same as evidence of absence? If you don't have research papers, then do the research! Don't just claim it can't be true. DW alberta is right, pseudoscience BS.
DW alberta
First off, it's CNN. I wouldn't listen to anything they have to say. Second, did you see the diet they ranked as the best? The DASH diet? They talk about Paleo being hard to follow hahahahah, that is an utter JOKE as compared to the DASH diet, where you have to count calories AND daily sodium, potassium, calcium and a couple others, and make sure you stay within this level and don't leave it. Sorry but I'm not an accountant. Eat healthy meats, vegetables, nuts and some fruits, lower your sugar intake. EASY!
Interesting, but has no bearing or judgement on the Paleo diet itself. Of course this is not calling us to eat what prehistoric man ate. The attempt at a Paleo diet is merely to indicate an escape from the "modern processed food" diet that we eat in the "developed" nations.
The processed food craze, which will kill us, is 80% of our health problems in the US. For those that do not know, a Paleo diet is defined as "eat whatever comes in it's natural form." No processed foods, colors or dyes. and NO HFCS for sure, and while we are at it, as little sucrose as possible. The modern diet consists of 175 grams of HFCS/sugar a day. Palue says "Keep your carbs under 50 grams a day, if you want to lose weight." Pretty simple, isn't it?
Simple enough not to be a fad.
Yay Dr. Wahl, and to add, Mitochondria LOVE real sunshine every day, and they love it when you sleep so they can have a clean kitchen (metaphorically) b/c that's when clean-up occurs from the day's energy production. So, food, sleep, sun. LOVE too.
very informative and fantastically presented. Thank you
She's a really good speaker. I wish she was a professor for one of my classes.
There is no such thing as "the paelio diet" we ate whatever the fuck was around us back then wether it was fish and clams, fruit and nuts, meat and grain, potatoes and corn and we lived with it
***** RESPECT YOUR ELDERS
+mbanana23456 That's what the paleo diet IS, what we ate for a shitload of generation, not the processed shit we've been eating for a couple of hundreds
Daniel R we didn't have a specific diet a shit ton of generations ago, we ate whatever the fuck we could to fight off starvation
Exactly. Different shit = variety.
+Daniel R With "processed shit we've been eating for a couple of hundreds" you mean what?
This was a great video. So glad to have found it.
Very insightful analysis about the role of agriculture on humanity. Her cowry shell necklace was just a bit of icing on her cake.
One of the most informative, yet simple dietary talks I've heard in a long time! I would love to see studies done on the long-term affects of eating paleo. My theory is that there would be major issues as a result of undigested protein.
All proteins from animal sources are perfectly digested by humans. There are 0 studies on the contrary
If all the vegetables and fruits were poisonous or not abundant then what did Paleolithic peoples eat?
Hmmm...
The paleo diet models Vegetables as the number 1 food source not meats.
Excellent talk...I have been following quite a few people in Paleolithic diet community...In last few years many famous names in paleolithic diet community moved away for the same reason... There have been quite a bit of my learning in these days...and mostly covered in the talk...I think she did not realize the honey is very sweet and is abundant in tropical forest and savannas...and there are tribes who consume a lot of them...and organ meat is rich in calories...so probably calorie is not a problem...We are evolved to handle variety of diets both low and high in nutrients.
Getting off the sugar treadmill is a big factor, as is moderation, eating fresh, whole foods whenever possible and variety, including eating offal in your meat intake.
What she said is true - there's no one optimal diet, but if we follow some basic guidelines, we can eat a healthy diet and, once you start eating like that, you'll wonder how you could have eaten the salty, sugary, greasy crap you thought was so delicious.
You don't have to go without the odd treat here and there, but you'll find that your tastes change as your body chemistry settles down so you won't crave the same processed junk you used to.
That's how it is with me, anyway. I enjoy the odd sweet, for example, but I don't crave sugar and when I do eat a dessert I eat a much smaller portion and go for a less sweet option because that's all I want.
We don't have access to the same foods that ancient man ate. The point of the paleo diet is to get as close as we can with modern foods. All she did was state that fact. Her summary was indeed a fairly good description of the paleo diet. She confirmed more than debunked.
you can tell she's very knowledgeable, passionate, and nerdy about this subject.
I was a vegetarian for 11 years. I'm epileptic and when I switched to the Paleo diet my seizures dropped off almost completely. Since then I've had maybe only 3 seizures in 3 1/2 years. I don't care what she says. I will never quit the Paleo Diet.
Robyn Masters that's the truth. So many people healing illnesses from eating animal foods can't be false.
That's great. Also: she doesn't say at any point to stop eating paleo or even suggesting that it's bad. She's an archaeologist who's challengin the naming of the diet as Paleo, cause it's not. It's just a diet.
You were probably eating processed junk food as a vegetarian
It's well known that keto/paleo diets are good for epileptics. I'm amazed you weren't aware of that fact for so long.
The big change probably has more to do with getting rid of processed foods, not the focus on meat.
I thought this video was excellent! Definitely one of the best Ted talks I've seen for a while.
Fantastic talk. Thank you, Ms. Warinner, for applying SCIENCE, rational thought, history, and FACTS to the current trend of quick fixes and shallow thinking. Well done.
How is eating mostly veggies and some meat trendy, shallow or a quick fix?
@Will.J thats a very big statement and completely debatable bordering on extremely simplistic but let me say that I am sure there is some truth to what you are attempting to express
I have read paleo books and they do not tell you to eat mostly meat they say diet would mostly be plant base diet, and that different region in the world would eat different types of food.
I really enjoyed Dr. Warinners talk. I have been using / following the Paleo diet for over 20 years. I really like and respect her position. I also agree with her conclusions on proper diet. People who follow the Paleo diet may be grabbing their flint knives and spears down from over the fire pit, but everything she said made PERFECT sense. I follow the Paleo diet because I am interested in optimum health, not to be a Paleolithic reenactor. I've not had any problems with the Paleo diet, per se, but I am more than willing to accept , adopt, and adapt my diet in light of new scientific data. I think Dr.Warinner provides that data.
Very interesting! You can tell she's passionate about this subject :)
It's nice to have seen a lecture by a research academic. It is an excellent lecture. Thank you!
meanwhile, BART KAY a senior academic, a scientist researcher with multiple publications in nutrition, has made a response video to this trying to debunk it. its interesting when academics try to debunk things.
@@scamdem1c and he succeeded.
15 years ago I tried the paleo diet and lost 8 kgs mostly from waste down... Regrettably I lost all my leg muscles..what I didn't do is train my muscles. Therefore consider to train to maintain your muscles.
Thank you. To sum up, the key is to have a varied natural diet without processed food, preservatives and sugars.
Paleo diet is way better than any other diet. Modern diet high in carbohydrate sucks!
In fact, our meats and vegetables aren't EXACTLY what they were 10000 years ago. But I bet that our "modern" beef is still way closer to our primal beef than the breakfast cereal that you see on the market shelves. The point is: To eat PALEO today isn't eat exactly equal to the Paleo era eating, it's about reaching 90% of precision and eating only natural, fresh, whole and unprocessed foods.
fascinating and informative!
judging by the comments, people have a hard time hearing what she is saying because they are so attached to their ideas of what paleo is. but this is such a smart, entertaining, and relevant talk. bravo.
Excellent presentation, thank you !
This title is inappropriate and misleading. She talks about the differences between what a formal or traditional "paleo" diet is in it's known forms but doesn't "debunk" anything. In fact, she makes it quite clear that the paleo diet may exactly be what we need to do for a healthier body and lifestyle
.
that's the point of her presentation the name, she is talking about name PALEO, you say the title is misliding so is using name paleo for this diet, i personaly think this is a good way to eat, but it is not paleo. it's like saying dog is cat, both are pets and there similarity ends.
She's not "debunking" anything...that's what's misleading
Douglas Lawson of course she is,,the MYTH that we need/should eat meat..DEBUNKED.
Dr. Mark J. Smith does an excellent rebuttal of Christina Warinner's lecture. Just Google "Dr. Mark J. Smith Obscurantism At Its Very Best."
Robb Wolf does an excellent dissection and refutation of this video as well, essentially giving a point by point criticism (with time references to the video included) of many of Christina Warinner's suppositions. Just Google "Debunking the Paleo Diet: A Wolf's Eye View - Robb Wolf."
Robb Wolf is the last person you want to be going to for nutrition advice. His credentials are as nonexistent as his understanding of nutritional science. He's a snake oil salesman spreading nonsense in hopes that you buy his books and paleo brotein.
Frederick0220 That is a logical fallacy. You can't just discredit a person on the basis of their credentials. You must assess a person's argument on the logic and evidence behind the argument. Furthermore, while Robb Wolf has no PhD, he does have a Bachelor of Science in biochemistry, and he did work as a research assistance for 5 years, specifically in the area of lipid metabolism. So he just isn't some regular guy, with no formal background in the subject matter.
Secondly, if his lack of a PhD in the subject being discussed causes you to dismiss him (again a logical fallacy), keep in mind that he buttresses his claims with the research of many people who are equally credentialed as the speaker, Dr. Christina Warinner. It would be like me stating that gravity is real, and you dismissing me because I have no PhD in physics, despite the fact that my statement about gravity is true and can be substantiated by evidence and argument from many physicist who have a PhD.
Finally, by definition, a snake oil salesman sells a product or dispenses advice that doesn't really work. The fact that many people can attest to Robb Wolf's advice improving all markers of health refutes that claim. I, for one, have followed his advice, and had lost over 50lbs (and I am continuing to lose ), improved every lipid measurement (overall cholesterol, HDL, LDL, LDL particle size, triglycerides), as well as reduced my blood pressure and fasting blood sugar levels. All of this was done, by the way, without enduring the rapacious hunger that I normally experience following a conventional low fat diet. My own doctor was flabbergasted at the results. If that is what a "snake oil" salesman actually does, we need more of them.
Frederick0220 The Journal of Nutrition and Metabolism disagrees, they have employed Robb to review submitted scientific trials for accuracy before publication. He's also a research biochemist and has been invited to lecture on strength, conditioning, AND nutrition by the Marine Corp, Naval Special Warfare, Canadian Light Infantry and NASA.
_They_ consider him an expert.
Primal Vegan All great points.
Registered Dietitians are fed their curriculum, via government standards, which were arrived at through dubious scientific methodology. I would argue that registered dietitians, for the most part, don't do the primary research or have familiarity with the primary research, which informs the nutritional guidelines that they are being taught in schools. Hence, most of them do not critically evaluate the science behind the information they are told to dispense.
However, many researchers, like Robb Wolf (who holds an undergraduate degree in biochemistry and did research in lipid metabolism for 5 years), Dr. Loren Cordain (a professor of health who has done extensive investigations into primitive diets) Dr. Boyd Eaton (a medical doctor who has been published in medical journals with respect to hunter gather diets), and Gary Taubes(a Harvard and Columbia trained science journalist who is world renowned for his science writing, specifically in nutrition) do have to be familiar with the primary research, and are quite versed as to the flaws in the research that dietitians take as gospel.
Secondly, as I mentioned above in a response to another respondent who had the same criticism, to argue that someone's position is valid or invalid, on the basis of just the degree they hold, is a logical fallacy(Argumentum ab auctoritat or argument from authority).
Furthermore, take any position on any issue, and you will have equally credentialed people take opposing sides of the same issue. How would merely having a degree clarify the truth, if two people, who are equally educated in a subject, could hold contradictory opinions on that subject?
However, if having an RD by your name confers upon that individual credibility, at least in your mind, then how about the following registered dietitians who advocate for the Paleo Diet or low carb diet:
1. Cassie Bjork
2. Amy Kubal
3.Melanie Thomassian
4.Kelsey Marksteiner
5.Stephanie Greunke
6. Aglaée Jacob
7. Franziska Spritzler
8. .Mary Trenda
9. Dr. Jonny Bowden (nutritionist)
So, if you dismiss someone's opinion on nutrition, just because they are not a registered dietitian, then you have to contend with the seven dietitians and one nutritionist mentioned above, who all advocate for a low carb or Paleo eating model. By the way, the above mentioned seven dietitians and one nutritionist who promote a low carb/Paleo is not an exhaustive list. These are just of the few notable people. There are plenty more, and their ranks are growing.
She does not mention B12 or the fact that our zygomatic arch begin to become smaller as we consumed more meat. We do not have large arches anymore like our ancestors who ate more plants. She also doesn't mention our brain compacity that increased from 300cc in Australopithics to 1400 in Neanderthals because of the increase of animal consumption. Also our digestive systems are short like carnivors. If we were majority plant eater our stomachs would be large and swollen like the great apes due to a large digestive track. Seasonal eating and if possible eating food from where your genetics are from are best.
She's trying to dispel some of the misinterpretations of Paleolithic diets - that's all. She's not bagging Paleo diets per se.
This just makes me realize we don't eat enough nutritional variety.
Paleo is working for me. I suffer from hypothyroidism and my inflammations are coming down. We all have unique physiology. So i guess there is no single diet which works for all.
we are ALL HUMANS. paleo worked for you, just like for thousands of others because IT DID. dont let someone gaslight you into believing otherwise. we have a species appropriate diet, or the proper human diet. this is the diet our ancestors ate. it is the diet that withstood positive and negative selection factors for hundreds of thousands of years.
this woman is wrong. BART KAY made a debunk video on this recently. bart is a scientist too so he knows what hes talking about. check it out
Very detailed explanation to have a whole diet with anthropological evidences. Very thought provoking indeed
Great pace she has. Thank you
Great presentation ...
There is some great info here, but the title is very misleading. It should be called, expanding or supplementing our understanding of the Paleo diet(s)
I know I distinctly do my best with meat as significant part of my diet.
I've been through all this detail of relation of diet to health, vegan iterations of all sorts, yes, all popular sorts,…. and omnivorism is clearly healthiest for all around body maintenance, repair, strength of tissues, body integrity,…
People that lived in plenty of environments around the world ate significant amounts of meat on a weekly or daily basis, as a matter of what works best for thriving.
Kind of off topic, but the “Clan of the cave bear” series was highly researched and said to be close to the natural nutrition at the time. Worth the read.
I love that series. Was not able to finish it due to moving away from the are where the library had those books but it was riveting to read.
Wow! Best talk ever. Great information.
