So a diverse diet in moderate portions is still my best bet? Check! I can do that.
@Jaded Cynic the military MREs were packed with junk food: candies and such, which provided a lot of calories. They are also low on fibers to save bulk. Troops can go for 2-3 days without having a bowel movements. Soliders recounted tales of black, hard, football size of shits that can't be flushed down a toilet.
There are ways that soldiers tell each other to keep their shits going: eat instant oats, drink more coffee, etc ...
Not exactly healthy. The military using it doesn't mean good. Okay? They used to explode nuclear bomb and order soldiers in exercises to "attack" through or around the nuclear craters in some measures of protection. First to train the troops to attack through a nuclear war and second, to get data on health effects of radiation exposure and the protection required.
@Jaded Cynic Kinda weird people pin weight loss for "proof" that certain diets is better or worse. It is only better at losing weight. Healthier overall? Questionable. Fast weight loss is used by doctors as a sign that "something's wrong". The military, again, using your yardstick, have problems with troops losing weights during sustained combat: increased energy expenditure, not sufficient time for rest and food. For them, the rate of weight loss dictate how long the troops can continue fighting before collapsing. In short, they actually need troops to maintain their weights and keep working; not losing weight. Soldiers in combat conditions require upwards and over 6000 calories per day. Good luck getting that in one sitting. Keto is being considered for recruits, to get them quickly in shape (because American 18 year-olds are getting too fat) during Basic Military Training (10 weeks). The Navy Seals are considering keto since apparently on ketosis, the body require less oxygen, allowing the SEALs to dive better. Other than that, they can't eat one meal per day and not lose weight; unless they are chowing down pure sugar.
When they need the troops to carry as little food bulk as possible while getting as much calories as possible; essentially getting as much calories in one sitting as possible, they fed the troops with First Strike Rations, which is Calories: ~2,900 per ration, Protein: 15%, Carbohydrates: 53%, Fat: 34%.
A good diet should maintain a healthy weight neither losing nor gaining weight. If you eat just 1 meal a day, it's harder to eat as much calories as 3 meals. Also, keto diet contains more proteins and fat, which make you feel fuller faster than sugars and carb. All in all, it means you eat less calorie per day. Simple. And you can't keep losing weights, it has to stabilise at some point.
More controlled studies and studies of participants in "The Biggest losers" showed that in the condition of eating less calories, the body actually adapted to burn less calories while resting, and eventually, most people gain weight again.
@Jaded Cynic You kept the energy levels cause the body sustained itself on your fat ass fat stores. When youre a regular weight person you cant fall on fat for more than a month. Even if you eat your entire days nutrient and caloric needs in one meal you still require your stomach digestion process to generate heat. The energy and clear head is the result of you cannibalizing yourself. It's almost euphoric cause the body doesnt have to expend any energy eating itself.
@@VT-mw2zb To add to what you wrote, there are scientific studies that show that a keto diet has adverse effects in the long term (as it's been used for a while for kids with epilepsy). For example: citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.603.3149&rep=rep1&type=pdf. It's great if it helps people lose weight (although it's absolutely not the only way to do that) but it's most likely not a healthy diet in the long term.
@Jaded Cynic Conflating weight loss with overall health is dangerous, especially if that weight loss is extremely rapid. By that logic, a diet of basically anything is healthy as long as you have a caloric defecit. (Which I hope you know isnt true).
"this craze goes back a long time, to the 80's and early 90's..." Thanks bud for making me feel ancient... LOL
Well, as far as fad diets go, that's not too young.
That is not take away that's I gathered from watching this video. Bit more nuanced than that.
Free radicals taught me you only get what you give.
Don't give up!
Free the radicals! The Rolling Stones taught me you can't always get what you want. However, if you try sometimes you just might get what you need.
That was New Radicals. They weren't free, sadly

I get my antioxidants by holding my breath.
Science checks out. *Shallow breaths*
EXPRAIN!
Lol wouldn't that be oxidizing yourself?
Am doubtful.
Can't tell if serious....
The more I learn about this stuff, the more I'm convinced we don't know a damn thing.
You should see one of Nutrition Facts videos on apple cider vinegar, it just like: It works? We don't know how? And our hypothesis was wrong?
Cody so well said. After 3 years of watching YT health videos, this is my honest same conclusion
Excellent overview of antioxidants.
One theory that I, personally, would like to see gain some interest is: Sourcing. Where do the tested supplement or nutrient substances come from? Because of the lack of evidence for or against efficacy and therefore regulation on supplements, some things (like calcium or iron) come in a variety of forms. Some are sourced as an extracted organic chemical compound, while others are basically... Rocks.
Such a thing could potentially change the results of an experiment, but it's a detail that's so often overlooked that I've read several studies that completely neglected to mention the delivery form of Vitamin E, Calcium or Iron used in the study. While that doesn't invalidate the published studies' findings, it does raise further questions.
As with so many things: More research is required.
+
Iron in box cereal is just iron from nails, It's useless for our bodies, but iron from vegetables is completely useful, of course the source matters a lot and that's why vitamin pills are a waste of money.
@@fenrirgg That's basically what I'm talking about. Supplement pills purchased at stores typically label their sourcing (such as B-12 delivered as cyanicobalamin), but the usefulness of each is under studied. Big box stores and drug stores usually (but not always) sell cheap crap and you shouldn't waste your money
Certain manufacturers make supps that are delivered in forms that are similar to what the body would get from a whole food source. They typically cost more. Are they useful? Unknown.
Of the supplement studies I've read (and yes, I'm that kind of a nerd. I find research reports fascinating), the tested supplement's delivery form (source) is either not listed or is the cheapest, most worthless bargain bin trash available. It saves money in the study materials and lets the researchers pay for more participants to lend credence to the results... But really? Should we be surprised that iron oxide is worthless as a nutrient supplement? Or even iron carbonate? C'mon. That study was an all-but predetermined conclusion. What about ferrous glutamate? Because that one's out there, too. It just costs more. Do you get what you pay for? I haven't seen a study yet that addressed it.
@@fenrirgg Metallic iron is not exactly useless (if you're severely iron deficient, even cooking your rice in an iron pot will help you a little bit), but you can only absorb a very limited fraction of it. Organic compounds containing iron (like those found in meats and some plants) are way easier for your body to repurpose for its own use. We use inorganic minerals in fortified foods and supplements mostly because they're way cheaper, and we assume that we can just use some number of times more of it to compensate for the difficulty in absorbing it. It makes logical sense, but it's not something we've really rigorously proven under a wide range of circumstances, so we should definitely look into it! Unfortunately, this would require (several) non-trivial studies for every different form of every nutrient ever, so it would be extremely expensive science with no chance of leading a corporation to a patent monopoly on anything, so it's going to be a slow process.
This is something I’ve thought about a lot I would guess that 60-70% of the supplements currently on the market would be poorly or not at all absorbed into the body, I think there are a couple reasons to this one being that many supplements in tablet form tend to contain a very high amount of filler compared to the supplement itself, whatever you see on the tablet is probably filler. You could solve this by providing the supplement in organic vegetable capsules that are easily dissolved by the stomach, this would work and the supplements I like to take are but another problem many supplements on the market face is the supplement itself being either synthetic, bio unavailable( poorly absorbed into your system in its current form) or in the case of vitamins d, a, e and others the wrong form for optimal health benefits. So I would agree and say that this would be a major issue in testing if this is not taken into consideration as much as it should be.
5:07 Add the issue of bioavailability to that list
I was suffering the most horrendous migraines a couple years ago. Lab results indicated very severe chemical toxicity of bromopropane and perchlorate. I did high dose glutathione IVs and it honestly saved my life. The migraines improved tremendously. I hardly ever get them now and they are way less intense. I don’t need a study to tell me that antioxidants are effective, my results spoke for themselves. I will say that the glutathione supplements were no help at all though, it was the IVs that gave me results. IIRC glutathione is the only antioxidant that does not become a free radical itself after it neutralizes one.
What are the IVs exactly?
I agree with you .. the guy is reciting some “pessimistic” results from studies he found over some resources he didn’t even cite.
We should pay more attention to who’s speaking in those claimed scientifically backed videos. Not everyone is a scientisit. And glad you had great results from you Glutathion therapy !
@AA.M-lz3to They literally cited all of his sources in the description.
I wouldn't say they cherry-picked "pessimistic" studies. The whole point of the video is that we don't know why results are inconsistent yet, and what factors lead to success.
Except the whole reason we have scientific methods in the first place is to minimize biases inherent to ANY personal experience.
Did you account or and eliminate other variables when reaching that conclusion? I don't intend to pry, it's more of a rethorical question.
Regardless, the moment to believe something is when there's sufficient evidence for it, and doing otherwise is the definition of irrationality.
Researcher: "Oh hey, this Mediterranean diet seems to work well!"
Dietitian: "Yep, It's the lean meats, nuts, plenty of leafy greens, and lack of extraneous sugar."
R: "Nah, I bet it's these antioxidants!"
D: "No, just use less sugar."
R: "Huh, these antioxidants don't seem to work for stress...I wonder what's wrong?"
D: "Less. Sugar."
I'd like to say i love this comment...ok i love this comment, i done said it....
Having worked in a health food store, I can confirm that folks mostly want a magic bullet that will let them not pay attention to their diet.
Classic example of looking at the same data and drawing different, sometimes wrong, conclusions
@@absalomdraconis I've been doing cheat weekends and eating decently healthy on the weekdays and I've been dropping...what 20 pounds a year for the last 5 years.....(ok, I kinda blew up when I went from being a floor tech to working on a pc all day) All it took was a few habit changes and steady effort.
Who would've guess that eating healthy real food and not food-like substances could be good for you!
You said anti and not ant-eye, I'm so happy.
The irony is that ant-eye looks more correct😂 english
Nah, he said ante

ante oxidant would have a very different meaning

@ SciShow you guys are just smashing it!
Thank you so much.
CAN YOU PLEASE DO A VIDEO on why eggs stick to the pan with low heat but don’t stick on HIGH HEAT???????
No. I don't feel like it.
Here is my hypothesis. There is a threshold to which there is too much or too little of the antioxidant. For example, if the body already could use the antioxidant structure for more immediate reasons, then the amont needed before we see "antioxidative" effects will be greater. On the other hand, if the particular antioxidant is not needed, and there are no immediate uses for it, then new problems might arise from extra energy and resources needed to expel of it properly.
I don't even know where to begin with this.

Awesome video. Maybe you could do a video about vitamin D, and why some people, like myself, are always deficient even when spending enough time in the sun and taking three times the recommended daily dosage in pills
this please!
This!!
Wonder if this is different with a spray ? Spray is meant to absorb easier and if you
Get Vit D on prescription it comes as a liquid
Drink more water, hydrate your body properly. Water is key to many processes in our bodies. Divide your weight in half and drink the halved amount in fl oz everyday. For example if you weight 200lbs you'd intake 100fl oz of water everyday no deviation stay hydrated. Simple as that. People underestimate the importance of hydration way too much.
Are you certain that you've gotten sweaty before the sun exposure? _If I recall correctly,_ the precursor is not simply in the skin, but instead specifically in sweat. Also, don't immediately wash off afterwards, let it soak in instead. And I think there was something about it binding to Vitamin A and both getting flushed out of the body.
At 4:04 you say "The one exception for supplements is that a combination of three antioxidants moderately reduce the risk of age-related eye disease". Would you please elaborate on that (which antioxidants? what study?). Thanks. Great show, as usual.
It may be important to note that anti-oxidants can become oxidants when they are grouped up too densely in our cells. However if you balance a multitude of different antioxidants they can balance each other out when they are all grouped up.
off the top of my head, it should be choline lutein and zeaxanthin. eat more eggs, guys :)
Long time ago from the 80’s and 90’s - oh god we OLD!
Selena Taylor still look young as ever tho 😸
zaaya yup, she cute as a bug in rug
Sneedy Ketler-Baumbach thank you
zaaya it’s the antioxidants! LOL!
Yes, we are!
Could quality of the product being tested make a difference? I have a hard time accepting the studies because I don't know where they are getting their product and whether the quality is good.
Then you have to consider the form of the antioxidant and how absorbent it is and the gut health of the individual. To me these are some of the variables that need to be answered when presenting research results .
Great! This was helpful and to the point!
Agree!
So i was playing the game everytime he said antioxidants I'd take a shot of tequila.... I'm hammered
Very good video. So much more credible than all the videos chasing popularity
This video will save me money.
Yep, unless you need them by recommendation from a physician, you're just spending money on supplements to make very expensive pee XD ESPECIALLY if you take the supplements the wrong way (Iron needs to be taken with Vitamin C, Vitamin D needs to be taken with calcium, etc. But most people don't do that).
Just get multivitamins and it is solved? You got everything to complement each other. Lol.
As for the study, have they taken into account the lifestyle of the participants taking the vitamin E for 10 years. Wonder why people on fruits and vegetables seemingly reduced risks on degenerative disease.
Secondly, not all supplements are created equal. Bioavailability of these antioxidants is a big factor for its effectiveness and how it is easily absorbed by the body. Scishow mentioned that dosage also matters.
Thirdly, supplementation is a holistic approach. Great combinations of vitamins, minerals and antioxidants are required to fully protect our cells from oxidative stress and prevent degenerative diseases.
Just my 2-cent on the topic. Well, actually it’s 3.
i used to take mdma every week for 2 months. almost 1 gram per week.
without the anti-oxidents i would be dead right now. i took multi-vitamins, 4000 vitamin C, 400 E, ALA, ALCA and for serotonin and dopamine production - 5htp.
with this combination i got no harm from the MDMA toxic, lots of energy day after and i could take it without loosing the effects because the body wasn't in trauma after each use since i insert so much anti-oxidents and multi-vitamin.
B3 specific and 5htp is the combination to make sure your body take the 5Htp and use it for serotonin and dopamine and not for creation of B3 since it's first in priority.
There have been published studies suggesting that free radicals can be harmful in certain circumstances but actually helpful in others, that they have a beneficial role to play in the body. It seems to suggest that the antioxidant/free radical debacle should be treated as a balancing act, not one good thing eliminating a bad thing.
Loved the Queer Eye and bubble bath reference!
Remember when the word "queer" was offensive though. I can't keep up with what's offensive and what isn't anymore.
Queer Eye recently said Ronald Regan's gel combed hair made him a better politician than Bernie Sanders. *(History: Ronald Regan blamed the LGBTQ for AIDS, which allower churches to persecute LGBTQ further)*
*Even Worse:*
They're entitled wealthy assholes. They kicked black old navy employees out of an old navy to bring white ones in for a show, worst of all they dismantle the LGBTQ movement to be treated respectfully, by being purposefully stereptyped.

Thanks, I was so confused about this.
The wide variety makes sense, also different gut microflora might alter what you eat.
But at least they don't have known bad effects - so if they are part of the normal diet, it's fine.
The supplements do have the side effect of making your wallet lighter, and giving you headaches when your mom insists you take them for the millionth time
Could you elaborate on how different gut microflora might alter what you eat? I am not familiar with that concept.
@@banehog Large portion of our digestion relies on the microbes in our gut to break down various compounds. And it can be different for everyone, what they eat, have they been in hospital/antibiotics etc.
So some of the antioxidants might not be digested and become bioavailable or they are consumed by microbes.
@@MauroTamm so you mean that what you eat will affect you gut biome? Because you said the other way around.
@@banehog Biome will alter the food you eat, change what and how it's absorbed or if it's absorbed at all.
Which will also affect what you can eat.
And the food you eat can affect the biome - killing some of it, replacing or introducing new microbes.
Perhaps it is (in most situations) like vitamin C. A lack of it would leave you susceptible, and likely, to get sick. Having an ADEQUATE amount means you're likely to stay healthy. HOWEVER, getting more than the adequate amount will not protect you, and in some situations may harm you. So skip the concentrated versions, and eat properly, and include some variety in your diet.
I'd like to know which three antioxidants exactly help with the aging vision
Me, too. My eye doctor promotes lutein and zeaxanthin as protection of retina against blue wave damage prevalent in computer, tv, phone displays. (See EyePromise brand) But unsure whether they are antioxidants referred to here.
Hi Ben, I'm Ian. SciShow is pretty cool and puts sources in their description. The 5th one down is what you're looking for: www.ncbi.nlm.nih.gov/pubmed/11594943?dopt=Citation

Great vid.
I saw a documentry once looking at blood serum levels of 2 antioxidant compounds and found supplementation of a blueberry extract lead to a spike in overall blood serum for antioxidants in the short term but lead to a depression far below normal levels over a protracted length of time similar to the insulin blood sugar response. In short supplementing with excess antioxidants reduced overall antioxidants in the blood for a significant period of time.
Cant find the source but it was a tiny sample reproducing an observed phenomenon for tv
Interesting thanks
When it comes to effects that take a long time to notice by someone other than the customer, the entire supplement aisle in a store can be safely considered the "I don't know. Maybe?" aisle.
Almost. There's vitamin D that a lot of people are verifiably deficient in, iron for the anemic, folic acid for future moms and lactase for us lactose intolerants
@@limiv5272 That'd be why I put that awkward qualifier in my original post. If you supplement a deficiency that's causing measurable harm, you'll notice an improvement, and so would anyone who knew of your prior plight. If you get something that promises to increase workout endurance, you'll probably notice in the near-term, unless you have an amazing placebo effect. If you grab something claiming to be clinically proven to help prevent your heart from exploding in conjunction with a balanced diet, no one's going to make note of how un-exploded your heart is no matter how long you live.
@PaleDale Milk chocolate and ice cream are very necessary for my mental health
Hank where do you get your shirts?? I love your shirts!
they're found in specially marked packages of supplements.. some ironing is required 🙃
Good work Mr.Green...
You know what else tracks with Mediterranean diet that might have an affect on life expectancy and health? Mediterranean heritage...
Population trends are not results, they are raw data from which to draw a hypothesis. It isn't a result until you do controlled studies.
Easy enough to find genetically pure Mediterraneans in the US and compare their health and aging trends against everyone else. People tend to get mad at those types of studies though.
I don’t think genetic variation among people is really sufficient to account for large changes
Didn’t they just under report heart attacks ??
Well glad I never got on the fish oil tablets and just eat a balanced diet.
Well, omega 3 (what fish oil capsules contain) is not an antioxidant, it's a fatty acid and it's something we need to function normally. But a balanced diet is really good! Studies are inconclusive on omega 3 supplements too. Personally I feel my mind is clearer when I take them regularly. But that's anecdotal.
4:36 that looks quiet a bit like Omega 3 capsules. Perhaps this be is the source of the confusion.
@@ChristopherWanha Yes. It's also known as a "supplement", I think it's easy for people to bunch them all together as snake oil/panacea.
Tbh I get heart pains sometimes if I eat foods with alot of fat in it. Taking those fish omega 3 pills really does help me relieve the pain and stress in my heart. They go someway to unclogging blood vessels. Especially cardiac blood vessels. Best bet though is to eat oily fish if you don't want the pills
@@ronniessebaggala362 I don't think they actually unclog anything, that doesn't make any sense, they need to be absorbed by the body before they can do anything useful. They are a tool, they're not actually dissolving the fat buildup in your veins. Studies show omega-3 is beneficial for people with heart problems, possibly by lowering blood pressure. One of their primary use in animals is breaking down fats for storage, so that might be what you're experiencing? More efficient handling of the fatty food you're eating. I suggest you read about it, especially if you're experiencing discomfort!!
Supplements haven't really been proven to work. I prefer them though since fish is loaded with heavy metals these days, they don't accumulate in the oils however but the muscles of the fish.
Blueberries are good with greek yogurt.
Zachary Laid Finding Freedom you’re right bucko
You don't need a control group taking sugar pills to figure it out either.🍶
One thing I rarely see people bring up when it comes to supplements is bioavailability. Sometimes people absorb nutrients better from certain foods than other foods... And this is part of the issue with supplements. Yeah, a pill might be chock full of something, but that doesn't mean it's gonna actually make it into your system.
Really is best to figure out what Monsanto is doing to wheat for example. READ! Roundup ready wheat requires glyphosate which is an antibiotic and herbicide. Hmmmmmmm. Don’t eat that. But guess what? Glyphosate is in the rain! So fight mold, fight antibiotic resistance. Take supplements like C that build glutathione and yeah you need to walk in the rain. The idiot you like so much knows nothing and said even less. Vitamin E is about the only vitamin with a not great track record. Eat for health. Eat bright colors. And fast.
It is so evident if you live unhealthy: dont do any sport activity, sit all day long, dont drink enough water, eat food that your body does not like, SURE the supplements wont work. But if you live a healthy life, they will 1000% WORK!!! My C vitamin level was so low that my gum was bleeding. None of the doctors told me to take C vitamin. I have figured it out myself and after 3 weeks (taking 5.000 mg C vitamin / day) my bleeding was gone. So yeah, antioxidants DO WORK very well if you use them in a proper environment.
good topic!
Whether the pills/supplements are good depends on who is funding the study... just like the recent claims to red meat effects on diet/health
@@WaterspoutsOfTheDeep Don't misunderstand my previous statement.
I did not say that consumption of red meat is good or bad. I said that the results are biased based on the study's FUNDING party.
Exactly thank you! I’ve been using fat soluble vitamins for twenty years and I look 10 to 15 years younger than my high school peers.
@@AssyrianFury Maybe you would look exactly the same if you hadn't spent all that money filling the coffers of the marketing wanks at the vitamin co.
Too late to know.
Over 20+ yrs of high quality and certain vitamins like coq10 and the best bioavailability in the correct form with the correct foods. I have found what works through trial and error. I’ve throw out what doesn’t work and keep when I feel and see results, I then stop to see if it’s indeed the supplement. Magnesium cod liver oil which is “food supplement “ vitamin E selenium and zinc. Thanks but my closes relatives which are ur siblings both never took supplements and I look 10 to 15 younger. I also eat healthy and lift heavy weights I bench press 315 lbs squats 405 lbs. I’m 44yrs old and I’ve got 35 year old guys trippin on me. Okay
A wise man says we'll see.
And I say, when we treat an idea, hypothesis, taxonomy or Theory as if it's a fact; it becomes eerily similar to a religious belief.
at the end I thought he was going to start quoting a song. "You know what is what, but you don't know what is what. You just strut."
"Which.... yay."
OMG I die every time.
4:34 and now I am hungry again, Thanks SciShow!
You cannot claim this by only looking at studies about vitamin E... There are so many studies which supports that usage of antioxidant supplements are beneficial.
The problem between getting results with diet but not with supplements is likely an issue of bioavailability or digestibility of the compounds. Either it is much easier to digest them with the other compounds in the food or the food provided an additional nutrient that is required for the body to make use of the nutrient, like how vitamin D is needed to use calcium.
Hey Hank totally unrelated but nice shirt where did you get it?
Looks like I'd better stick to just eating my veggies rather than trying a supplement
I tried to eat right and I stopped eating supplements for a while. That was a mistake. The one bowl of cereal I had every other day was the only fortified food source and the supplement is necessary.
The variance of foods in the proportions of which yield for vitamins at an optimal level as well as other nutritional structures is overwhelming and extremely hard to manage purchasing, preparations and consumption without producing waste that it suggests to me that dietary nutrition, shopping for it and meal production should be a class right along with every other necessary curriculum...
It's just another example of the failures of our education system.
@@MetaphysicalAxiom You're right, we should be learning how to look for and purchase healthy food, however, eating healthy is going to vary between people based on their nutritional needs and what access to food they actually have based on a wide rang of very systemic factors. For some it may not even be possible due to those systemic factors.
_
Fortified foods (like cereal) can be helpful for getting certain nutrients when their normal sources are unavailable; in fact we fortify certain foods for just that reason (see the early 20th century pellagra outbreak and it's results). This doesn't you shouldn't try to eat healthy, just that how you go about may not be the same as how someone else goes about it. For me, that involves including veggies, beans, and whole grains in my diet wherever possible. You might have to do something different, and that's okay.
@@scarletletter4900 sure, many ways to achieve nutritional requirements. (if I had it my way, I would have a Jack in my arm and I would take all nutrients possible, intravenously and then a pill that was like a sea monkey of carbs you know what once in my stomach it expands and makes me feel full.
Poop, Maybe once a week.
Save time. Get more done. Fix the world's problems. Achieve a semblance of economic viability. Dialed in perfect optimization...
Shrug.
The only way I get my nutrition as I do is because I don't have many other choices.
Great!
I want that fish shirt you're wearing.
There's also the fact that my exact needs are different from my mother's. So giving us the same dose of an antioxidant could help one and hurt the other.
Heck, I'm pale and outside a lot yet have low vitamin D levels, so not all variation is obvious like age, sex, and size.
@PaleDale that is highly debatable. The body itself produces top-grade anti-oxidants which work extremely well, but if you ingest a lot of rubbish anti-oxidant supplements, the body lowers its own production as it thinks there is already enough in your system.
@PaleDale I don't think anyone is debating whether the biological mechanism of fighting free radicals with anti-oxidants has any value. The OP asked how would you even know what amount will help you and what amount will hurt you, and you responded "anti-oxidants will not hurt anyone". My point was that *ingesting* too high levels of anti-oxidants can result in your body producing less, which *will* hurt you. In real life, getting too high levels of anti-oxidants means taking supplements, as getting too much from regular food would be very difficult.
Why no specific mention or indication of source, what combination of 3 antioxidants protect from which eye disease?
Mr. Green is the best! He has me LOL 😀 with his facial expressions and sarcasm. He's by far the 🌟 of SciShow and SciShow Psych
Keep in mind that many cancers also take advantage of antioxidant mechanisms so too much may accelerate cancer. I do research on this and we are looking in cancer treatment in this field.
Do you think there's a away to cancel the damage the antioxidant did?
i think we need a variety and with supplementation studies you’d need to have a consistent diet with everyone because you can have one person that consumes a surplus of vitamin e and that’s maybe just not documented the way it should be in these studies
Product idea: veg smoothie concentrate in a pill
One thing that gets on my nerves about the antioxidant discussion is that nobody seems to understand, let alone elaborate on, the importance of antioxidants *actually making it into our cells* as opposed to just floating freely around our bloodstream. Do dietary antioxidants actually make it into our cells? Do they make it into our mitochondria? If not, do they do us any good in the blood stream? Are there harmful free radicals floating freely through our blood that dietary antioxidants can neutralize? Or are most ROS within our cells?
You gotta mimmick how antioxidant appear in food, what types group together in ways that might compliment each other. With tumeric it doesn't work as well by itself, but add black pepper and the body absorbs it way better.
How does putting a battery on you tongue effect this?
Thanks buddy, I almost throw up taking thosr huge pillls everytime. I was always skeptic of them for being not measurable but my dad keeps telling me to take them. Now I'd show him this video and then offer him a mid ground of antioxidant rich diets instead.
I've been saying this for a long time, but there's something about the interaction between the many molecules and compounds that you find in biological thing that just isn't there in isolated extractions. Just like you couldn't take all the chemical ingredients of a living thing and mix it together and get something alive. The arrangement and interaction matters. The emergent properties matter. And I never seem to hear of anyone studying that stuff much. I'm all for science, but this is an area were a lot of traditional folk medicine got it right. There are other compounds in the raw ingredients that make it fundamentally different than any of those compounds would be on their own. I don't know, this makes common sense to me, but it feels like other people totally ignore it as mumbo-jumbo when it clear as day that there is some kind of hidden but fundamental set of rules hidden in the structure and ratio and balance of things. How else could you explain life and consciousness springing forth from inert matter. Life is clearly more than the sum of its parts, and the delta between the raw materials and the end result must necessarily lie encoded in the structure and arrangement. There's clearly information there that we don't seem to be picking up on.
And yes, I'm very stoned right now. 👍
There is a profit motive in studying isolated supplements.
great video on antioxidants very informative i have a video on that subject as well
4:35 Whoa, that mediterranean diet escalated quickly!
Pomegranate on zucchini, meat with raw parsley, a suspiciously greasy hummus and dried olives in... ehm, olive oil?!
Mitochondrial and cell structure or functions are supported by fats better than they are sugars.
@@MetaphysicalAxiom yeah I know, but as Italian I am quite picky about "mediterranean diet" and I had a WTF moment. Now I understand that maybe those are recipes from middle east or Greece or Cyprus. My comment was written instinctively, without thinking.
5:30 or a lot of supplements don't have what it says on the label and you need different antioxidants, because the radicals travel from one kind to another kind of antioxidant..
until they somehow become harmless, we don't know yet, idk maybe I don't remember
I thought its because anti-oxidants are best taken as part of the wholefood, so by extracting the supposed anti-oxidants away from the food it loses it's power. Its like taken the wheels away from a bike because it is the wheels that move forward but without the rest of the bike you go nowhere.
Thanks
You and curious droid should have a shirt party
Maybe success or failure rate depends on gut bacteria.

Another thing that companies lie to the consumers is the antioxidants in skincare.
Antioxidants are very unstable in skincare products, so there might be very little of it left when you're putting it on your face, and there's no evidence saying applying topical antioxidants would do anything in a cellular level.
The reason why they put antioxidants in products is to stabilize the product itself and make it last longer. But telling people that their products have antioxidants to help them fight free radicals is just a blatant lie
What probably happened with the tests where it help people,
is a placebo effect.
They where told it would help, so it ended up helping even though it shouldn't have.
He said the big women’s study of Vitamin E supplementation included a placebo cohort that was compared with the cohort receiving the vitamin. In that study, the Vitamin E was moderately effective as compared with the placebo.
There may be a difference too to those that are sourced from actual foods, and ones that are not.
It's funny to see how many people talk about the benefits of daily vitamins and mineral supplements, but the oldest people in the world don't bother with them. Kind of makes you think it's a whole load of crap, huh?
But since there are many different types of antioxidants maybe the answer is in the type, considering the opposite results in the studies. I know reservatrol and Astaxanthin are supposed to be good for the heart
totally unrelated to the video, but I like Hank's shirt
Preservation of oil! If you don't take your vitamin E, add a capsule or two to any oil you want to extend the shelf life of.
Love my anti oxidant antiinflammatories and antimicrobial properties products.
It does me great things
Refined Sugar is the sweet sweet poison killing everyone slowly but with a state of euphoria for our taste buds
I get my antioxidants from fruits and vegetables. Sometimes tea.
@Secret Sauce is Overrated Depends where it's grown.
@Secret Sauce is Overrated I don't even like tea because it's bitter. And caffeine gives me headache. I only drink it like once a week. Coffee like once a month. mostly water and milk. And I heard milk isn't good for you either lol.
I ingest antioxidants through organic green tea and such.
I think this is a problem of observing something that is good and measuring it like its a cure all for everything without taking into consideration the things that can damage its good effects.
dairy is number 1 in saturated fats and eggs are number 1 in cholesterol intake. red meat is a 2a carcinogenic and all processed meats are level 1 carcinogenics and also increase your cholesterol. milk contains estrogen which increases your risk of getting cancer and yogurt is basically condensed milk. so we have all of these cancer causing products that we consume way to much of that also give us cholesterol based diseases that we see as early as our 40s and 50s.
taking antioxidants while consuming so many animals and animal products is like taking an axe to your boat while pouring epoxy into the holes. ya the epoxy is pretty good stuff but you are doing more damage over time that is way worse
damn! first time i'm here so soon after an upload! (I live in GMT+8, it's like 330am here lol)
GMT +10 here!
Cool its GMT+7 herw
A healthy diet with great variety of fruit and vegetables will always be more beneficial than eating processed foods and taking supplements.
I like your shirt 🙂.
I’m a regular plasma donor 🩸 so I need to have high levels of iron & antioxidants! Love eating healthy
Wait you mean eating foods is better than taking supplements? derp...
What these Studies have not taken into account was the other lifestyle choices of the people taking the supplements.
They often do take into account such confounding factors in studies. Most researchers do care about the validity of their results
@@limiv5272 I seriously doubt that, because researchers can't watch people 100% of the time so they wouldn't know if they're eating 10 Snickers bars or lying about doing cocaine.
Nutrition is very complex with so many chemical interactions you need to keep track under controlled scenarios explains why it's so damn hard to find a conclusive results, which by themselves, the inconclusive ones we have now, they don't necessarily mean that anti-oxidants doesn't work, the correct question should be like, when where and by how much do they do work, cause it's pretty much nonsense and unlikely to think that they wouldn't/don't.
I wonder if one company keeps it research with them supplements...
In short, don't rely on pills to give you nutrition you could otherwise get just by eating good food.
The take away is that diets rich in antioxidants work but expensive pills do not
And also, supplementing with antioxidants, diminishes the beneifts of exercise or training
Could painting ourselves with Rustoleum work ?
Perhaps whole foods work in a different way than their parts?
What about antioxidants in skincare?
Nobody has Vitamin E defficiency.A,B,C,D and zinc yes
