Just listened to this again, I stopped eating liver after listening to this six months ago and my rosacea, that started after going carnivore, is almost gone. I've also had less histamine issues, ankle stiffness, edema. Things seem to be improving. Thanks so much Judy for spreading the word.
These anecdotes don't prove anything though. Eating mostly meat and eating liver regularly cleared up my rosacea and histamine issues
@@thestuff4321 sure they did
@@alexxx5749 Yes. I made it up because I work for "big meat"
Lots of old people eat liver here (weekly), many of them are in their 90s, have been doing it for years and they are healthy.
@@1966MrAlex I eat liver every day, not much but I eat it ( I love it I'd like to eat more) It's my supplement. I'm on a Lion diet, I only eat ruminants and water salt. I'm very helthy yes. I eat every 6-7 days other organs like testicles hearts lungs...all of them are from lamb.
Wow. Thanks for sharing this, Judy. I appreciate your willingness to address controversial topics as well as the research you put in to ensure you provide balanced information.

Thank you for this heroic service. 🙏
Oh great, more food we can't eat. No plants, no meat including fish, so I guess it's just air from now on.
Kinda tempted to go on the bullet diet at this point
Why would it be just air there's tons of options for healthy food
@@benjaminbritt7862 Because there's some health nut who tells you just about every food is unhealthy. If you listened to all the extremists, there would literally be nothing left to eat.
who said no meat? Did you even watch the entire video? He never said no meat or no veggies or no fish.
@@faryalkhan5930 eggs and butter are fine, nowhere near the VA as liver... now, there are other reasons some people MIGHT have issues with eggs or even butter, but it isn't the A...
What I love about you is that you are open to discussion and flexible to change your mind. I asked this question about vitamin A toxicity on Twitter and here on RUclips and no one asked or they call you a lunatic. This is why I have so much respect for you. I took the advice to take a lot of ADEK and high doses of vitamin D and now I have chronic pain in my back, and joints, I'm recovering from an injury to my ankle and now I have a meniscus injury. I'm pretty sure this was caused by extensive take of all these vitamins.
That's why one thing doesn't fit all, we all have to find what actually works for us as individuals.
Thank you for sharing Judy! 🙌
Out of sheer curiosity I had a look at this gentleman's website to see what prompted him to conclude he was suffering with vitamin A toxicity. His elimination diet coincidentally is also a very low plant-toxin diet, essentially a beef and rice diet. There are too many people to count who have reversed their skin issues and/or autoimmune issues by limiting plant foods, but it's got nothing to do with vitamin A content, and everything to do with cutting out oxalates/salicylates/histamines/phytates/lectins/phenols etc etc. I think for this chap probably solanine in the nightshade family was a big culprit but it could have been a combination. He never even ate liver and caucasian people in particular are very poor carotenoid-converters. If anything, his symptoms sounded like significant nutrient deficiencies including but not limited to zinc and vitamin A, and reducing the metabolic burden of metabolising lots of plant foods has brought him relief, along with reducing copper in the diet. It has absolutely nothing whatsoever to do with vitamin A. This reminds me of when Ancel Keys determined that saturated fat was the devil based off of terrible data and interpretation.
He never ate the liver? Never supplemented with cod liver oil or took supplements? Then why does he think it was Vitamin A😮
Also he's talking in the very beginning about people with vitamin a toxicity. Theres no way they got that from eating actual liver. Almost no one eats it anymore, and it would be unusual to have a long, controlled study done on a group of people who eat it regularly
Hi Judy. Very interesting video. This is not a new concept. In the 1980’s organ meat consumption was discouraged because of this very reason. An important fact I learned from Dr. Paul Mason regarding LDL cholesterol is that if a person is not weight stable ( in weight loss mode) his/her LDL will increase dramatically. Mine did just that. As an oldster I really appreciate this information. I know you are sticking your neck out to present this information. I truly believe this information will be very helpful to many. Thank you again for sharing your evolving point of view. 👏👏👏👏👏
Wait, "organ meats" in general? Its not only liver?
thank you Judy. Grant rocks. His blog is a life saver.
Should I be concerned about taking astaxanthin and/or lutein for eye health ? I’ve read confusing information about whether these carotenoids can cause vitamin A toxicity.
yes. you should be. there are a TON of forms of vitamin a that are not labeled as such. it may worsen your condition. big Pharma is generally useless unless your symptoms are that bad- in which case it manages the symptom not the cause.
interesting interview ... Grant is well learned on Vitamin A ... thanks Judy for content, the best!
So glad I found this very interesting talk regarding liver, kidney & organ meats which I have never eaten but have always wondered if I did the right thing, I did take Cod liver oil time to time but not enough to be toxic. I have been trying to start a Keto/Carnivore diet as I am trying to eliminate/start different foods to help stop seizures started in 2005 after numerous blows to the head by my x partner in 2004. I stopped the epilepsy meds in 2012 as they were not working or had terrible s/effects & suffer 0-5 seizures every month around the same time as my hormonal change, I am 60 & its still the same. I had a bad fall June 2022 so stopped alcohol & various foods while researching Keto, saw a Naturopath last Sept who started me on a low carb diet with 60gms of protein daily, which did not help much but it was a start. I am waiting for a consultation with Professor Kay I heard in an interview I was watching with Dr Chaffee, I contacted Dr Chaffee who was very helpful and when I mentioned Bart to him he said he is very knowledgeable as I am not sure about diet, especially being nearly vegetarian most of my adult life.
Thanks for confusing everybody 😢
This person is eating beans, grains, no fat but has a problem with vitamin A, really who are we kidding here? He has SO MANY other reasons to be unhealthy….
By the way you make it sound like liver is mostly about vitamin A, but it has so many more nutrients!
So many reasons to be unhealthy, yet he is so healthy?
Ummm he's not unhealthy, in fact he's very healthy. He eats rice, bison and beans. He has zero retinol in his blood. Living proof that vitamin a is toxic.
@@ladybugwest909 Vitamin A deficiency ultimately causes blindness. You don't want that. Charities send Vitamin A pills to poor countries to stop the children from going blind due to deficiency. It's no joke. Have sense and stop going to extremes.
He never mentions ever eating liver, unless I'm missing it. He just assumed all of the food issues were Vitamin A, for some reason. He only eats rice, beans and lean beef now, so I'm guessing he eliminated what was really causing his problems. It's usually gluten, seed oils, plant toxins, sugar, etc. I'm happy his health is better, but it's hard to believe it was Vitamin A, since he never apparently even ate liver.
The man literally saved his own life when he was about to be in dialysis
i followed his diet for 2 years as a 17 y/o. beef, rice, beans, and an apple only each day.
Did it work?
@@Seeker2400 yes
@@Seeker2400 i was very low in vitamin D though. i drained beef fat so i got almost no fat in my diet for 2 years. no fat = no vitamin D either
why did you do his diet? Did you have health issues? And did the diet resolve all those issues?
@@ThomasTumasyan did you do it for reversing Accutane damage?
it saddens me a bit that so many people (carnivores?!) disliked the video. Grant's presents his material with an outstanding confidence, based on his long background and experience in the matter. It is known that vitamin A is probably the most important risk related to animal based diets, now even seemingly with some risk for plant based diets. If the carnivore community respected more the possible unknowns of this diet, such diet would have a higher probability of succeeding even with better success stories than we have to today. Being humble about science is paramount!!! So, Thx, Judy!!!
Confidence=/=actual science. He presented zero evidence that dietary A was a problem. All the horror stories were about supplements and/or meds.
@@robinbeers6689 nope. All his science is listed on his blog. Kind of hard to present that much science on a short video.
@@jillherrmann1416 Thread necrophilia is alive and well I see.
@@robinbeers6689 whatever helps you sleep at night. Seek help.
@@jillherrmann1416 Thanks for the chuckle.
I had a very hard crash while on carnivore (with liver) 2 weeks before I found Dr Garret Smith who is friends with Grant. Not only does this explain everything, including PUFA toxicity (detoxes along the ALDH pathway in the liver). This paradigm accurately and constantly predicts phenomena.
What diet regimen are you on now?
@@purpose6113 vitamin a detox diet. Dr Garrett Smith has website and is the nutrition detective on you tube. Diet restricts vitamin a and there is an emphasis on nutritional density but he tries to allow flexibility to suit each individual. Having said that vitamin A and beta carotene are in lots of foods.
@@Soilfoodwebwarrior nutritional density?
It's interesting that you pointed out that a lot of these symptoms are similar to hypothyroid symptoms because thyroid hormones and vitamin A share the same transport protein Transthyretin so it could well be connected.
Also maybe the big dosing of Iodine actually helps with this. I used to take Accutane and it fucked me up for the last 7years, i'll try the iodine protocol with Lugol's and see if it helps
I was thinking the same thing as I was listening. My attempt at carnivore always ended in my T3 tanking and dizziness every night plus dry and blurry eyes. I never connected it to Vit A toxicity until now. There must be a connection with Vit A, thyroid and copper, and probably many other things.
How is it going? Are you solving your issues? If yes, what are you eating?
@@matteosemeghini6939 Yes reducing vitamin A was helpful for me but I have had more significant improvements from reducing my iron. Donated blood, stopped using a cast iron pan and avoid fortified foods.
Interesting thread
Thank you for this information!!
I thought I was doing great adding chicken liver smoothies and organ pills occasionally with my mainly carnivore (eggs + dairy included) diet for 3 years.
By the time I was almost done with my 2nd bottle of a new liver/kidney blend mixed with other organs, I was dealing with a dry red patch on my right cheek that wouldn't go away for over 2 months!!!
I went out of town for 5 days, didn't bring my bottle of organ blend. It was the only time period where the patch started to fade and become less dry. It's almost gone after a total of 8+ days of no organs. I can't imagine what it's done to me internally. Never again!!
Testify sister !!!!
We truly live in a modern world, and even as we try to bring ourselves back to the basics, we still behave like modern people, thinking we need to take supplements and eat things we don't even find good tasting, and do absurd things like counting calories in order to be "healthy". None of this shit existed before the last 100-200 years. How do you think homo sapians and their ancestors survived the last 2 million years? It wasn't by taking daily vitamin supplements that's for sure.
I think it makes sense that our ancestors ate the organs as well, but probably the portions were much less. Today you can go buy pounds/kg-s of liver easily, couple of thousands years ago you would have to do a lot of hunting to get that amount of liver.
So I think organ is probably fine and good for you in small portions, but it is so nutrient dense it is easy to over consume.
This would also mean the "eat organ" advice is not necessarily bad but you also have to be careful of the portions.
organ pills lol
I would like to add that maybe the gelatin casings on the organ pills might have been kind of hard on your gut after a while of taking them regularly. Not denouncing your experience though.
According to cronometer my intake of vitamin A and copper is suboptimal.
I have some minor problems that look like it could be vitamin A deficiency, slightly red eyes, returning infections.
I am taking a multivitamin like 3 times a week, I forget it a lot.
I started eating 100grams of cooked beef liver yesterday, but now I'm doubting if it isnt dangerous. The opinions vary a lot.
Thanks for the information. Vitamin A is a must watch between all health variable. Keep giving us the information and everyone should make their own research.
Liver is a high histamine food which is probably why it is making some people itch, skin issues, etc. it is also a high sulfur food, which some people have difficulty breaking it down properly, so will cause various symptoms if this is the case. I absolutely DISAGREE that liver causes vitamin A toxicity. No science here and this man and his methods of deduction are absurd in my opinion. I have trouble with liver unfortunately because of the high histamine and high sulfur, as I mentioned earlier. I actually like liver a lot and I hope that those that want to eat liver and don’t have a histamine or sulfur breakdown problem should definitely keep consuming it. Don’t let this ill informed person scare you away from things that work well for your body!
I agree. I don't take health advice from amateurs. Vitamin A is a vitamin because it is essential and because a deficiency can lead to diseases.
@@GenesisReveal The problem is that people go from eating zero liver and avoiding Vitamin A to overdosing on liver and cod liver oil. There is a sane proportion in the middle somewhere. People used to have liver about once a week, which was probably right for most individuals.
You didn't even look at all the research papers he has posted on his blog. You're telling people to eat something that could be toxic without ever doing one bit of research, just because you like liver. Talk about uninformed.
The research is there for everyone to see… vitamin A has been debunked. The rats that died in the original study did it for lack of zinc not vitamin A. You can live without vit A. It is not essential
But it is good to be aware of the possibility of Vitamin A toxicity !!! Many people think that if a little liver is good then a lot must be better !! This presentation serves as a warning that too much of a good thing can become a very bad thing !!
It defines logic why people would eat large quantities of liver when ancestrally, liver would be shared among many and reserved for pregnancy, growing children and those with higher metabolic demands. We can't help stupid😢 I am guessing as a computer software engineer Grant was spending a lot of his time indoors. He didn't have a physically demanding labouring job like digging ditches, landscaper, concretor, brickkayer or even farmer outdoors all day in the sun. If he was not employing the use of his muscles, there would be downregulation for the need for Vitamin A. Being sedentary slows down kidney filtration and if you are consuming liver day in day out, you are asking for trouble. Gosh so many conflating variables. We need more evidence before going down this rabbit hole of Vitamin A being a toxin.
Grant literally got his ideas from studies on polar bear liver btw
How closely are humans related to polar bears? Polar bears are adapted to a high fat diet which is why they can tolerate high levels of vit A. This explains the variable experience in humans. It depends on your genetics and how well you tolerate fat in the diet. Those who originated close to the equator probably tolerate fat less as they are more adapted to fruit and vegetables so are efficient in converting beta carotene to retinol. Those further away exposed to freezing cold winters are more tolerant of fats, less efficient at converting carotenes to retinol. They are able to tolerate fatty foods and preformed Vit A. We also tend to spend most of our time indoors away from the sun and may not be getting sufficient Vitamin D. Remember, Vitamin A and D work in unison. If Vitamin A was toxic then you would also be reacting to meat and all animal foods. Perhaps you're best to go plant based with lots of veggies, fruits and wholegrains. That's right, they are also toxic to humans. Look at those who thrive on just fruit but I bet they are also living at the right latitude. Perhaps the solution is to move to where the latitude best suits your constitution.
Thank YOU SO much Judy! I’m on day 10 of Carnivore 75 Hard and am SO grateful for YOU and ALL you do to make the world a better place!
I'm going to be stopping CLO and limiting vitamin A for the time being. I do wonder whether D3 and / or K2 protect against A toxicity though.
So how come when i started eating raw grass fed beef liver i was hitting insane pr's in the gym and my skin and hair look incredible?
You were probably deficient in some nutrient that it contains.
Is there any way to rid excess vitamin a in the body? Thanks
Just uptake your vitamin d3 levels.
Book: The Miraculous Results of Extremely High Doses of Vitamin D3, by Jeff T. Bowles
Ok so the retinol in our skin, eyes and other tissue is good but the one stored in the liver poisons us? How does that make sense? Why does the retinol in our eyes or in our skin not poison us then? Why is the tissue of liver toxic when storing retinol?
Vit A is not the problem, the dosage is...!
That's what the interview is about.
also, why did God put vitamin A in all the red meat, including liver which has an almost perfect vitamin profile. It makes no sense whatsoever.
Having a healthy and functional liver of your own is the key. Up your taurine mate.
Is tasteless gelatin a good choice besides beef?
Judy, I am so curious to know if you did ask the carnivore community about whether they did liver and organs, compared to those who don't and their LDL levels?I would really like to know if he is talking about CAFO liver or grass fed, grass finished liver? Since the liver stores toxins I think it would make a huge difference. My dog gladly eats grass fed organic liver once in a while, but totally refuses to eat CAFO liver after trying it once and throwing up.
The kogui indigenous tribe would say that it does matter how much vitamin a you get from your mother actually. And that is why they have the mothers go on a strict white foods only diet. Because the white foods have no vitamin a and possibly no carotenoids either
OK, so what is a good high source of Arachidonic Acid which is free of retinoic acid? Egg yolks and beef kidney both have about the same 400mcg of retinoic acid per 100g of food. I would think eating 100g of beef kidney per week would be doable and it gives you 400mg of Arachidonic Acid, which is an essential fatty acid. If you are deficient that may be necessary for some time.
@Pro4x Trdpro I've found real functions for vitamin A talked about, like in the eye. I'm not getting vitamin A regularly and it could take years to become deficient. But, I really don't see this guy saying how it isn't a vitamin.
So do people improve after they backslide?
Hi! How did you treat your CKD?
Everyone has to make their own decisions and trust their body. It’s good to hear more opinions but I’m not going to fret over having 2-3 oz of liver every week and cod liver oil once in a while. If I start to feel bad or not like the taste then I need to trust my instincts.
I think people in this community tend to be over achievers and if they think a little is good then a lot is even better. That’s when you can run into problems.
Cause a little bit of poison ain't so bad. Lol. It's cumulative and insidious. Good luck.
@@ladybugwest909 dosage makes the poison/medicine. 🤷♂️
@@davidhartley6232 Exactly. Thank you. Too much of anything is bad for you, even water. Some idiots had a water drinking contest on a radio show a few years ago, and the winning idiot tragically died.
A few ounces once a week is likely fine, but a huge NO on the cod liver oil, that stuff is toxic (rancid)...
Are you saying you like the taste of CLO? CLO might be bad because of the PUFA content rather than A
Thanks, I honestly have been taking CLO and eating liver. I know I have lesions on my liver and I really need to consider this. I have become very weak 6 months into the carnivore diet.
Carnivore might be too extreme. There is probably a level of carbs you can tolerate without derailing your health goals. Usually 4 ounces(dry) white rice or a baked potato and just 1 serving of fruit will keep you lean and healthy if you continue to eat meat.
Eating liver is not the cause of liver problems. My supermarket, has not had it in 6 months.
Yea just keep starving yourself. I'm sure that really helping out your liver.

@@keithbarbaro7590 you're basing your assumption that eating liver is not the cause of liver problems on your supermarket not having it in stock? LOLOLOL

So high LDL could be indicative of excess vitamin A?
Chris Masterjohn made a few RUclips videos about vitamin A toxicity, and these short videos are very informative. Two quick takeaways are 1. A fatty liver resists taking up excess vitamin A, and this is a problem, and 2. Adequate vitamin D can be protective to vitamin A overdose.
It's amazing how no one else mentions this. There are experiments where chicks fed massive does of vitamin a failed to grow but when fed concurrently with equally massive doses of vitamin d they were able to thrive. Vitamin a is toxic in the absence of vitamin d. Even vitamin e has been shown to reduce vitamin in a toxicity and increase it's usage in the body.
So in a nutshell, if I want to try carnivore, what should I eat?
Also, what are good sources of vitamine D besides the sun?
Can anyone speak to fractionated fish oil for derivatives, to support Rantes and genetic stuff...I'm curious if it being a derivative of fish oil would make it ok? Ingredients: Active Fractionated Marine Lipid Concentrate … 300 mg
[standardized to 150 mcg Total Pro-Resolving Mediators (PRMs) - 18-hydroxyeicosapentaenoic acid (18-HEPE), 17-hydroxydocosahexaenoic acid (17-HDHA) and 14-hydroxydocosahexaenoic acid (14-HDHA)]
Fish oil, unlike fish liver oil is not high in retinol
Ive been taking clo for about three weeks and im so ill.
Thank you Judy !! Question for Grant - is he worried about excess Arsenic from White Rice ?? Great discussion !! No more Liver maybe even butter !
Would it not be reasonable to have our Vitamin A level tested first before completely omitting liver/kidney from our diet?
If our Vitamin A level is ok, then is it really going to be an issue to eat liver/kidney periodically?
His cutting vitamin A out of his diet would have no effect in the short term because there's at least a six month supply in the liver. Eczema flareups resolve by themselves. He proved nothing. Vitamins A and D are excellent for skin conditions, including eczema (sunlight exposure is best for the D). The vikings were once the only people in Europe not deformed by rickets because they ate cod liver regularly. The only acute toxicity cases are from vitamin A in pill form, or a few arctic explorers eating polar bear liver. This fellow seems well intentioned, but also seems to want to prove his theory despite there being no hard evidence to support it. That said, I am also partisan, because I LOVE cod liver and eat it all the time. Thanks, Judy--
Agreed
Extraordinary claims require extraordinary proofs.
@@Michelle-Eden What proof would you define as extraordinary?

I think this is a great video and something to really think about since probably most people are not aware of liver toxicity. Obviously the animal liver collects all the toxins, so that makes sense.
No. The liver does not 'collect toxins', that is not why you shouldn't eat much of it if you're going to have any (you certainly don't need it)... VA toxicity is the problem...
@Pro4x Trdpro No, it definitely doesn't - unless you are talking a diseased liver, like fatty liver disease, cirrhosis, etc, then it might be 'toxic', but it still isn't 'storing toxins as part of its normal function.
The amount of mis/dis-information on the interwebs is your own biggest enemy.
Again, VA (Vitamin A) toxicity, aka Hypervitaminosis A, is the biggest potential issue from eating too much liver.

@Pro4x Trdpro your choice to believe something that isn't true is a choice you are free to make...
@Pro4x Trdpro yes, in the same way that drinking too much water will kill you.
animal liver doesnt "store" toxins, it stores nutrients and eliminates toxins
Vitamin A is required to burn fat. That's why they are always together, plus vitamin E. If you eat a low fat or vegetarian diet, you could conceivably get retinol toxicity. But still you would have to be eating a ton of liver and nothing else. Most of the symptoms Grant described can be multitude of things. Right now there is not even a good way to measure retinol levels in the body. The theory really does not sound very solid.
There is. Biopsy. 20-30% of people analyzed in studies are vitamin A toxic.
@@SaludTactica Climate and genetics may play a big role as well. Some people could be very deficient as well and not know it.
It will kill you slowly😅, I have been eating beef liver, kidneys, brains and some other beef, chicken and pork organs but mainly beef at least since 1961. Still no medication and healthy.
For those of you who are carnivore and use retinol TOPICALLY, please be extremely careful. For me, it resulted in vitamin A toxicity. The vast majority of people are probably vitamin A deficient and don't have any issues with using retinol regularly, but I had to stop using it. I had all the symptoms of vitamin A toxicity, and those symptoms went away when I stopped the retinol. Stopping organ meats didn't do it.
Please look more into the research. Even people in Africa who claim need vitamin A the most were found to have plentiful liver stores!!! They need good protein and zinc in Africa not vitamin A.
Sorry if it I missed it, but can anybody actually find a legitimate source showing vitamin a toxicity from beef liver? All I can find are from people using non-liver supplements or from people who have weak livers for other reasons.
Vitamin A toxicity in most cases can only be discovered by a liver biopsy, because the research very clearly shows that the vA levels in the liver do not correlate with what's in the blood. If you watch the "Vitamin A at Epidemic Levels" video on Dr. Garrett Smith's channel "Nutrition Detective", you'll see him going over studies where they've done liver biopsies on dead people and see how truly rampant vA toxicity is. There is also a video of his going over case studies where people were poisoned by liver consumption.
they cannot, it does not exist
My grandma ate liver all the time, hated the smell. She died at 97yrs old, very healthy all her life. It must of been all that liver toxiciticy that took her out and not the injury she got from getting hit by a car when she was on her walk.
Your grandmother was a middle aged woman before glyphosate was on the scene, so she was unlikely to be deficient in the nutrient most able to protect the body from vitamin A-zinc, which glyphosate chelates from the body.
Vitamin A toxicity is greatly exacerbated by industrial agriculture.
Also, this is a logic fail on your part-would you conclude, just because someone’s 97-year-old grandmother smoked her entire adult life, that smoking is harmless or that smoking-related disease doesn’t exist? 😝
she probably would have lived to 150 had she not eaten liver and got hit by car
Sometimes people thrive despite their choices not because of them.
not only have i been eating liver, i've been eating calfs liver, which is even higher in vitamin A. Been eating pretty much of it for over 2 years.
Don't have it for every meal. Once a week is probably enough.
@@robinlillian9471 how many oz per week?
@@purpose6113 0 ounces a week, that's how much, because it's a poison. How much is enough of a poison?

Although I think Grant is genuine I think there has to be more to the story. Man-made vit. A. plus improper lifestyle versus. Natural vit. A. plus a more natural life style, i.e. sunshine, earthing, fasting ect. Thank you Judy for daring to go down this path. I think we need to always have an open mind and pick around all these fine points to get to the root of our issues. Bravo !
Exactly. The vast majority of vitamin a toxicity studies I've seen have been from synthetic vitamin a. There are so many good micronutrients in liver and it's been an ancestral food without issues. Perhaps a polar bear liver will cause toxicity, but I doubt many are eating that.
No, natural vitamin a will give you as much toxicity as synthetic.
@@erosramasotti1080 maybe if you're eating polar bear liver, but I have yet to see any evidence showing normal beef liver consumption leading to toxicity. I saw the mouse study but they gave them an insane amount of liver. By that logic I could die from drinking a couple gallons of water. I think anything in excess can be dangerous.
@@JasonFuhrman I agree with the anything in excess, but by your "anything in excess" logic, how do you define excess when it comes to liver? It has clearly been demonstrated that an excess amount of Vitamin A is super toxic to both humans and animals. Only a tiny, tiny amount of beef liver will give you the adequate RDA of Vitamin A, so what is an excess amount of beef, pork and chicken liver in your opinion? And what is "normal" beef liver consumption?
@@erosramasotti1080 I feel like about a half pound a week or so is completely fine and advised by experts like James Dinicolantonio. He advises a half ounce to an ounce and a half a day.
Thank you for this interview. Do cows have enzymes or bacteria that neutralize plant toxins? If not, why do they eat it and how do they survive?
They do! They have four stomachs!!!

I prefer your viewpoint Judy where you address other things like gut issues and skin problems , thyroid issues . This guy is fixated only on vitamin a toxicity
@@NutritionwithJudy I did listen to it , and just to clarify , I do keep an open mind , which is why I actually listened to this . But my opinion or feeling if you will , is your guest wasn't himself being open minded to other factors . When you told him that his list of vitamin a toxicity symptoms also mirrors that of gut issues or thyroid , it felt like he didn't want to ponder or acknowledge it for whatever reason. And the fact that there aren't any credible tests for this except for a liver biopsy? But I do appreciate you bringing this guest on and also asking him some great questions .
@@NutritionwithJudy and @marc gutierrez : why is this hard to answer? If you have not eaten a lot of Vitamin A, and you have thyroid symptoms, then you will go down the thyroid route, and not down the Vitamin A-toxicitiy route
@@NutritionwithJudy Regardless of the topic, I applaud you for having an open mind and not merely trying to please the masses. Thank you for being an actually GENUINE “content creator” on this platform.
@@marcgutierrez1173 he has addressed the thyroid and gut issues over and over. he did not heal by taking thyroid supps or going on some autoimmune paleo diet. he had no gut issues. he healed by doing one thing, removing "vitamin a" from his diet. if it was his thyroid, then how did his thyroid recover (and all his health issues) with his diet of rice/beef/beans? that makes no sense. thyroid issues don't heal like that. sorry. read his books if you do have an open mind as you state. all the answers to your questions can be found in those books. but you won't read them, you'll just keep on eating liver and thinking it was his thyroid. too bad, for you.
Just like the body can make glucose if you don't eat carbs, the body can make most fats without eating fat. Although there actually is fat in beans, rice and lean meats.

@@NutritionwithJudy
Thank you so much for sharing this with me. I haven’t had blood work done (not at a place where I have the $ for it yet). I have seen other vlogs that talked about the importance of copper in order for other nutrients to be able to be used by our bodies.
@@NutritionwithJudy I don't think oyster would be an evolutionary consistent source of copper for most people living on earth
what about eating liver only when your body asks for it? In the beginning, I ate a small amount of liver almost every other day. Then I didn´t want it anymore. I don´t think the liver is bad itself, It depends on the person, I´m not from the US so my previous diet maybe wasn´t so high in vitamin A, I added dairy to my diet when I started the carnivore diet, so before that, it was moderate amounts of protein, grains and some fruits and veggies. I wasn´t feeling my best, and carnivore definitely improved my health.
@@NutritionwithJudy Just for reference, in my country (Argentina) the recommended dose is taking liver once every 15 days or once every month depending on the person. The amount per meal is the size of a steak. I guess people in the US are eating too much or too little because it´s not part of their culture.
I completely agree with you regarding what you said about eating liver until you no longer want to eat it. I'm 10 months carnivore. At the beginning of my carnivore journey, I was eating a very small amount of beef liver every single day, and then around the 8th-month mark, I just didn't want to eat it anymore. My guess is, I was deficient in some nutrients to begin with which is why I had such a craving for liver. So currently I probably add some beef liver once a month.
Good luck with your carnivore journey and good health to you. Feel free to head over to my small YT space.

@@jillherrmann1416same
Anecdotal but after eating more eggs and butter recently, then having a 350 gram serving of liver I had neon yellow urine and headaches all night (I drank enough water, yes) which seems to have been caused by overdosing vitamin a
Well yea… that’s 12.5 oz of liver. You shouldn’t consume more than 2-3 oz a week to be on safe side. The medicine / poison is in the dosage.
It doesn’t mean liver is bad for you.
The neon yellow urine is from riboflavin in liver. You get that from taking Vitamin B2 supplements.
I’d be interested in seeing a study that differentiates between vitamin A from liver vs supplements. I haven’t seen a study that proves vitamin A toxicity from meat/liver.
Same. I'm searching studies as I type this and everything I find is synthetic vitamin a.
Yes, I would like to see that too. It doesn't exist though. Not even a case report.

I will take the advice of the Paleo Medicina people who have been using the Paleolithic Ketogenic diet to treat most of the diseases of the modern world. They said there is no limit to the amount of liver you can eat....and in fact advise eating at least a pound a week. They have not seen anything but good from its inclusion in the diet.
That's what I kept thinking too. But then, they do have a big problem with compliance to their diet. And honestly I don't see hard evidence from them about needing the organ meats. Not sure...

@@raynaquigs7879 Well from everything I have heard from them, organ meats are an important part of their diet in order to insure optimal levels of vitamins and minerals.

I have heard that those who don't eat organs could be deficient certain essential factors.
There was a Dutch lady who went there and followed the exact protocol, but still grew new tumors. They only have a handful of success stories I am afraid.
I have heard strange stories. I don't trust them at all.
How much liver was he eating or was he supplementing? What was his thyroid function? If metabolism is slow trying to rev it up will be problematic if other nutrients are inadequate. There is very little iodine and selenium in liver. Iodine needs to be replete before you can utilize all those nutrients available in liver including all those b-vitamins which are required by many enzymes. Optimal thyroid function is mandatory.
We only use up enzymes reserves when vitamins and minerals are deficient . The higher the vitamin the greater the affinity, thus the greater the efficiency of the enzyme. We don't know what SNPs he has. Has he investigated to find out? This may help to isolate the problem. For example, the build of phytanic acid found in animal foods and green leafy veggies can build up in individuals with the genetic disposition and cause vision problems such as cataracts, scaly skin, deafness, gait and balance problem. Using this as an example and because ruminate animals, eggs, dairy also sources of retinol how would you know which was to blame? Phytanic acid levels come down when foods are eliminated from tbe diet. Blood levels only tells what is being trafficked from one site to another or what was recently ingested but tells nothing about what is happening at the tissue level. It could be a transport issue, receptor, enzyme issue, we don't know and shouldn't be too hasty in labelling a nutrient a toxin without irrefutable evidence.
Do we know what his kidney function status was before he started eating liver or supplementing with Vitamin A? Supplementing is always fraught if kidney function is not optimal. Fat solubles will accumulate as they can't be easily excreted by under functioning kidneys.
Riddle me this, how does Paul Saladino cure his eczema eating liver but Grant develops eczema eating it?
Judy can we get a SNP analysis from Grant and Paul? It would be so fascinating to compare.
We have enough viewers here who benefit and those who don't to run a comparison study. It would clear up this issue once and for good. 😊
People talk about certain carnivores looking great for their age....so does Grant. I believe he's at least 60? Great episode.
When I got sick, my carnivore doctor really pushed me to start eating liver since I was doing muscle meat and salt. I don't think liver really did much for me but based on my recent hair analysis I don't think I'm absorbing my meals well either. I'm wondering where the B6 in high enough quantities is supposed to come from without organ meats since the other doctor I went to recently insisted that that comes from leafy greens alone. The all food is trying to kill us narrative is getting exhausting really . . . I now feel a little confused because my great great grandma was nearly blind because of nutrient deficiency from great poverty and starvation in childhood and it was attributed to lack of vitamin A.
Chicken wings and salmon are very high in B6, pork and beef steak also have some a bit less
these people are quacks ginger. eat fruit vegetables meat beans grains nuts and you will be healthy
The real problem is probably glyphosate in grain-fed liver. I'm switching to grass fed ASAP.

I like liver. My husband does not. This means when I have prepared liver I have consumed too much. I never knew.
I’ve read some of Ray Peats work on thyroid and vit A so it would also be interested to research that perspective also. He says If your thyroid isn’t functioning optimally (which most people have some form of hypothyroidism these days ) you should not have much vitamin A at all. If your thyroid is functioning optimally you will need more. It could be why some power struggle with vit A more than others.
So if your thyroid is functioning well, eat vitamin A until it breaks down. Have you ever heard the saying, "If it ain't broke, don't fix it?"
@@GenesisReveal A reasonable amount of Vitamin A will NOT make your liver break down. Vitamin A deficiency ultimately causes blindness among other symptoms. That's a real problem in poor countries where children tend to be malnourished. Have some sense and don't go to extremes.
probably because Vit A slows down metabolism. Hypo people already have a slow metabolism.

Excellent discussion with an opposing view to the carnivore food “religion” as It can sound a lot like the vegan food “religion”.

There are many other things that cause osteoporosis. Most people eat the standard American diet are going to be nutrient deficient anyway. There are so many variables that can cause these issues and vitamin A RDA is a moving target?

So how in the heck does he even know that was an issue with him?
The symptoms overlap.
Vitamin A is heavily fortified in Western foods
Exactly. He started with his conclusion and then backfilled with a bunch of assertions backed up by zero real evidence.
As a carnivore (5+ years now) I started by eating liver once every 2 weeks or something like that because I thought there was a chance that doing the carnivore diet wasn't giving me the all the 'vitamins and nutrients' that I required, and so I went with the 'safe route' and started it by having liver relatively frequently. But within 2-3 months, my body started rejecting the liver completely. I would put the liver in my mouth and my body wouldn't want to swallow it whatsoever. I was completely rejecting it. I would compare it to periods in my life when I had way too much sugar or cake or something, and you're not full per say, your body is just telling you something like "hey, enough of that already, I can't deal with that right now"
Since then, I've been carnivore-ish (having alcohol 1-2 a week, and some dessert here and there) with some periods of strict carnivore in between, and only have muscle meat. I don't know if many people have felt the same way I felt that time I had liver, but it was an intense feeling of "this food shouldn't be going into my body right now".
In general my health as a carnivore-ish has been great. My body composition is perfect. Sometimes I look myself in the mirror and think to myself "this is cheating; I haven't worked out in a year and look better than ever". My posture improved massively, joint pains slowly went away (I have/had a bad knee which I find is still improving after 5 years). Never had bad acne, but I notice that when I eat certain foods, seed oils in particular, I get some pimples on my face.
I never experienced any serious dumping or detox or w/e you want to call it in my journey, although I have gotten sick with 'flu'-like symptoms here and there, and I can safely correlate many sicknesses with an excess of poison foods (carbs, alcohols, fried stuff).
Also, I've had liver, I think a couple of times, since then (but this was years ago) and I didn't feel the extreme disgust then. It's all very fascinating
As as side note, for anyone that's interested in an almost unrelated topic:
I've been learning a lot about toxins and poisons lateley and I have come accross the idea that viruses don't exist, that bacteria, even though they do exist, don't make you sick, they just proliferate (they were already there before the disease even happened and are in us (yes most of them, even the tuberculosis one) all the time) in areas that are sick/diseased and appear to be taking care of the dead/dying tissue.
All this is to say that this vit a is poison idea goes in line with the idea that, among some other things (such as stress, lack of sunlight, etc.), poisons are the things that actually make us sick. There are these things we can call toxins or poisons that affect our tissues in a negative way, and that this idea that there are bugs out there that are out to get you is nonsense.
Anyone that is interested to learn more about this go to odysee and search for Dr Sam Bailey. She has great videos explaining all of this. Other people to look for would be Dr Tom Cowan, Dr Andrew Kaufman, Dr Mark Bailey, Mike Stone at viroliegy.com
I want to see Grant debate Joey Schwartz on this topic. Can you make it happen?

i for one had been working on clearing out my arteries and "thought"with all the good stuff I seen in liver , it was good because of the enzymes it has, now I realize snce I had eaten it a few times, I been wondering why I been not feeling like myself and with little energy, this is why I think, so back to eating chicken turkey and other muscle meats!! thank you for the news!!!! To tell you the truth, i always hated liver, mo made it at home, and maybe thats why even then I lasked energy and such,,,wow!!!
according to Dr. Eric Berg on the liver , it has the Vit A that is not toxic, if you research what he is showing , he explains the whys and why nots about beef liver, calf liver does not have as much nutrients as the grown beef catlle liver,,, so you can;t go with people's assumptions and so on. I admit I was wondering , but checked it out for myself, matter of fact you cook the liver with orange jiuce it will do away with that nasty iron taste!! here is the video>>ruclips.net/video/1ZmXKYL240E/видео.html
You can always find someone who believes something is toxic.
It’s like people are unable to be reasonable.
Sorry bro that life is complicated
Liver is a bank of vitamins and minerals..why the "A" is put there ??????.
14:22 regarding what a safe amount daily would be, the doctor says it used to be 5000 RDA and then it was lowered to 3000. I checked wikipedia, and the safe amount is now down to merely 900! One day it will be none! To quote: "For U.S. food and dietary supplement labeling purposes, the amount in a serving is expressed as a percent of Daily Value (%DV). For vitamin A labeling purposes 100% of the Daily Value was set at 5,000 IU, but it was revised to 900 μg RAE on 27 May 2016."
I eat liver 2-3 times per week.
Yeah, this is a hard pill to swallow... too much overlapping confounders to believe the accuracy.... some of it may be plausible... just based on the idea of "too much of a good thing isn't good" - neither is vit D a vitamin... there is a balance needed with hormones for the body to function optimally....
Grant: Eating liver causes chronic vitamin A toxicity
Judy: But it has other nutrients how about 3 oz a week?
LOL
I believed that liver was a good first food, and I prepared it for my grandchildren. This now horrifies me.
Watch the video Dr. Berry did on the 7 busted liver myths.
@Kristi Vice I would not be horrified. This entire video was him stating: a) synthetic Vitamin A is incredibly toxic to humans b) preformed Vitamin A (derived from animals) is added to foods our bodies are not designed to contextually register. Therefore he has not proven that vitamin A consumed through an animal product like liver is a problem. This guy is also an engineer and geologist. His own website states he has no medical experience. I agree with the other reply (Sonja) who recommends following Drs like Ken Berry instead.
@@francescac3747 Liver has helped me! I don't have such bad acne now, my periods are almost painless, and stamina is improved.
@@sonjawalkerreactionscommen3501 me too. Acne significantly improved after eating raw liver and mag glycninate. Thankful for docs like Ken Berry :-)
Walter Breuning's favorite food was liver and onions. He passed away a few years ago... at the age of 114. That danged old toxic vitamin A!
Why in history is Vit A coming up now? May it be the synthetic Vit A added to milk, food etc? hmmmm
I’m really glad you had Grant on. I read his first e-book long before eating a carnivore diet (started eating this way a little more than a year ago). Somewhere along the way I bought into the beef liver craze and abandoned my caution of consuming too much vitamin a. I ate a lot for weeks on end-probably a pound a weeks for two or three months. Then my hair started shedding excessively, my right hip began to throb, and my weight started to climb despite nothing else changing in my diet. The weight always goes back down and the hip pain stops within a few days of stopping liver (unfortunately, I’m still trying to recover from the large amount of hair loss). I say always because I’ll periodically try putting it back in my diet, and I get the same results. I did it as recently as a few weeks ago. I wasn’t even consuming more than the equivalent to an ounce a week. Only two weeks of a very small amount and those same symptoms returned. I’m even having issues with eggs at this point. I know a great many people value eating liver, but this information is incredibly important to be aware of especially if you aren’t feeling great.
Same things happened to me !! I was taking Ancestral supplements of liver everyday. I stopped them because of the copper. Seems like the more I try to eat healthy , the worse I feel 🤷
Eggs, papaya and carrots were the culprit for me in the past
What you describe Tex is exactly what happened to me - I ate massive amounts of beef liver when I first started carnivore, and started having excessive hair loss, dry itchy eyes, irritability etc, and when I stopped eating it for while because I didn't fancy it any more the symptoms went away. Just last week I had some lamb's liver and also some liver pate and the hair shedding started up again, and I also had red itchy eyes and an itchy exzema-like rash on my neck. I'm staying away from liver now, which is a shame because I love it. I'll stick to heart as my go-to organ meat now I think!
Your hair loss is probably from carnivore causing high cortisol levels due to carb deficiency forcing it into the glucogenesis stress pathway. Cortisol is cannibilising your hair follicles
I read some comments on here and truely many are hard headed, and don't care if they take in toxins or not Hosea 4:6
What this guy doesn’t tell you or more likely doesn’t understand is that Retinoic acid is needed on the receptor for activating Thyroid function, T3 and so it plays vital role in thyroid homeostasis.
The poison / medicine is in the dosage. Having liver once a week isn’t going to hurt you. Or having 2-3 liver capsules daily will actually give you enough active form vitamin A to hit RDA, and not go over. One liver capsule has about 830IU of vitamin A. Just google a vitamin A calculator and put it in.
What he also doesn’t tell you is that Vitamin A active form and Vitamin d3 work synergistically to reduce Th17 and autoimmunity.
And you wanna know what else can give you orange skin? Thyroid dysfunction.
And he said liver contains plant toxins? The liver is not a storage of toxins. I have no idea why people listen to this guy. He just speaks with conviction but it doesn’t mean he knows what he’s talking about. You’re doing your audience a disservice by giving this guy a platform.
Supplements and true vit A retinol are very different....
