I’m going to keep this EXTREMELY brief, and very simplified. If it’s too simplified for people’s liking let me know, but I don’t want to bog people down with information. Comment with thoughts, suggestions, other studies you’d like to know about, or more areas to read about the china study.

What is The China Study?

When discussing an all meat diet, I’ve heard The China Study brought up numerous times. I wouldn’t say all of the science in it is bad, but the author makes conclusions you can’t make, generalizes, and leads readers to the WRONG conclusion.

The China Study is actually a book written about a number of “studies”. Dr. T. Cloin Campbell of Cornell University and some of his colleagues studied the diet hundreds of thousands of people in China. They ended up publishing that animal protein contributed to a plethora of disease. This was a gross inaccuracy on his part for the reasons listed below, and contributed to God knows how much suffering.

Where did it go wrong?

  • Campbell links “animal protein” to cancer and autoimmune disorder’s. The studies in the book linking “animal protein” to disease, are done based on casein (a protein in cow’s milk). He generalizes and instead of being clear “casein causes…..” he writes that “animal protein causes….” This is wrong. Casein and meat are NOT the same AT ALL. He discusses casein causing Type 1 diabetes but doesn’t talk about gluten’s role in Type 1 diabetes, or fructose’s role in insulin resistance, or sugars role for that matter. The main mistake he makes, that caused God knows how much suffering, is lumping casein and meat together.
  • Campbell doesn’t look into carb consumption or sugar consumption. He omitted information in order to get the result he wanted. This book could easily have been just as popular if he didn’t omit key information, and was specific that he was talking about casein (not animal protein in general).
  • He suggests limiting cholesterol food to ZERO. We’re slowly finding out that cholesterol actually isn’t bad for you, and suggesting people eat zero of it is ridiculous. We need cholesterol to form our steroid hormones, process vitamin D, and form cell membranes.

Where did it go right?

Casein is linked to cancer and autoimmune disorders. I suggest avoiding dairy almost as much as I suggest avoiding gluten. But lumping dairy in with meat is a huge mistake. They are not the same.

What we can take away from it:

Be careful what you read. Most studies on diet are done badly and lead people to the wrong conclusions. Casein (dairy) should be avoided.

Further reading on The China Study:

This is an easy read that’s very comprehensive

Chris Kresser wrote a blog post about it, and it’s really worth reading. It covers way more than this oversimplified post.

Some readers have mentioned Michael Greger and nutritionfacts.org. This is one of the (many) reasons I think that doctor is a crook. He’s looking for anything that supports what he believes instead of looking for the truth. Compare what he writes to what Chris Kresser writes about The China Study and see for yourself. He lists The China Study as some of the evidence of plant-based diet without actually looking into the science behind it.

      So you didn’t debunk anything at all…..

  2. Steph on April 7, 2018 at 9:36 am

    If you want to read a really great debunking of the China Study from several years ago, check out Denise Minger’s blog. She got a book deal out of it and wrote “Death by Food Pyramid”. Dr Campbell also got really upset about her blog and I believe they got into a big argument on Amazon in his book review section. Funny thing is she was an English major in college at the time she debunked it. Campbell was pissed! It was some great internet drama back in the day.

    It’s unfortunate the vegan gurus, and their devotees, keep spreading pseudoscience..If that was not enough, they are always, trolling on youtube, insulting people who eat meat.

    • Mikael on April 7, 2018 at 2:31 pm

      I’m skeptical about people who have vegan in their username. Seems like they identify with it too much. I mean they would have to risk sacrifice their persona if they were to be critical about the vegan diet(/life style).

      • Matthew Pickering on April 8, 2018 at 3:23 am

        Using your system of logic, can we not say that we must sacrifice our current persona/frame of reference regardless of if we are vegan or a meat eater/omnivore? This is the continual process of death and rebirth of what we know in relation to new information that presents itself. If we use that same logical process in regards to an omnivore, we can say that one risks sacrificing their persona around cultural norms of eating meat. An example would be the cultural ties one has to meat. It surely is quite a transition to make these kinds of changes(Thanksgiving, Christmas, social gatherings, etc.). I suffered from an auto-immune disease for years until I switched to a whole food plant based diet. It can be very easy to focus our attention on the extremities of what the media portrays (in this case group identity such as veganism) instead of conducting a throughout examination of both the opinions, ideas, and scientific literature behind both sides to create a well rounded, minimally unbiased opinion. I would highly advise that you give a vegan diet a try; more specifically a whole food plant based diet. If you end up doing so, make sure to take a vitamin b-12 supplement daily. Sometimes our direct experience with something can trump all the controversy. You ultimately have nothing to lose and you might find life altering benefits out of it as I did. 🙂

        • Mikael on April 8, 2018 at 7:42 am

          I wouldn’t call myself a vegan or an omnivore because I don’t identify myself based on my diet. I would say that I’m on a vegan/omnivorous diet. Feels wrong to say that I AM something instead och DOING something when eating a vegan diet is just something you DO.

        • Kenn Macdonald on April 8, 2018 at 12:03 pm

          Hi Matthew Pickering
          1) Mikhaila comment was about people who put the word ‘vegan’ in their username, and this appears to publicly declare an emotional identification with a diet/lifestyle/morality. Looks like virtue signalling to me. That is all Mikhaila said, and I agree with her statement, but you seem to have reacted to her statement, and not thought about it.
          2)You advice to Mikhaila that she give the vegan diet a ‘try’ tells me you have not read, or understood, Mikhaila’s blog at all. If you were to read what she has spent so much time researching and writing about, you would realize how inappropriate your advice is. Mikhaila writes this blog based on her bodies experience of the food she eats, and her research is an attempt to understand what happens to her body when she eats certain foods. Please go to the first post, and read from there.

      I will add that I saw tremendous progress on a ketogenic diet but the symptoms did not fully go away until a transitioned to a whole food low fat plant based diet oil free.

  4. Erik on April 7, 2018 at 11:57 am

    You are correct. Nutrition information from a vegan is worthless. They became vegans because they did not believe in using animals for food. No problem with that. But then they have to justify being a vegan (and convert people to their vegan religion) by making up stuff like cholesterol will kill you.

    I actually met T. Colin Campbell recently. I guess he is “healthy,” but he is gaunt and looks like he has one foot in the grave.

  5. StruanM on April 7, 2018 at 3:24 pm

    Hi Mikhaila,

    My wife has sever health complications specifically relating to diet (we’re still getting to the bottom of it). She is much more tolerant of less fatty meats like chicken and game than beef and pork (lamb is out of the question). Is this a common thing for people with dietary problems? Are less fatty meats more easily tolerated, generally?

    We have tried the GAPS diet (its a real doozy) which is basically bone broth from either beef bones or chicken bones for a week straight and that was very hard on her. We shan’t be repeating that experience. The SCD diet was better, but still not ideal.

    • Kenn Macdonald on April 7, 2018 at 9:18 pm

      Hi StuanM.
      If fatty meat is a problem, it might be because we are not used to digesting fat. I found it helpful to take a Lipase (fat digesting enzyme) until my own enzymes could get up and running. Beef bones are better for broth I think, especially if you’ve cracked them to expose the marrow, or the marrow is already exposed. Chicken bones(especially chicken feet) are OK, but not as good as beef bones(marrow and knuckles), oxtail, good info here also https://www.sott.net/article/232028-Traditional-Bone-Broth-in-Modern-Health-and-Disease

  6. Michael Shepard on April 7, 2018 at 5:29 pm

    The best critique I’ve seen on the China Study was written by Michael Eades, a medical doctor who has written a bunch of books on low-carb dieting. You should give it a look.


  7. Carl S on April 7, 2018 at 6:08 pm

    Would be interesting to hear about your efforts to find a common underlying problem with the foods you can and can’t eat.

    Personally i am looking in to histamine. My food sensitivity’s seam to map decently to the histamine food list’s.

    • Kenn Macdonald on April 7, 2018 at 9:36 pm

      Hi Carl S
      I have heard that the ‘nightshade’ family can be a problem. Have you looked at that?

      • Carl s on April 9, 2018 at 2:53 pm

        I’m I have read about that, but the fact that raisins make me feel really bad made me think diffrent. But now going through it in my mind that could be sugar rushes followed by really low blood sugar levels.

        Lactose is the only one food I get instant (a few hours) noticeable physical effect from digestion issues and gas.

        I used to have problems with the skin flaking on my fingers for years, that went away when I stoped eating gluten.

        My current thinking is that I will need to do an elimination diet like mikhaila, but that seams like a big big thing.

    michael gregor belongs to a vegan society with all those other doctor’s whose mission to convert everyone to veganism. All of his ‘research’ samples are bias toward vegan living. For example he says eggs are ‘toxic’ and cause heart disease and cherry picks research to support that. Many societies rely on eggs, indonesia for example and other non meat eating societies like india. If you look at the longest lived people (actual real people who make it past 80, for example), you might find they eat eggs. Genetics is a huge factor in your natural lifespan, smoking and too much alcohol will cut it short though. Stress causes cancer and heart disease, which is why a lot of the ex servicemen and women suffer these things early in life comparatively. So The china study was proven to be a fraud for various reasons but again the basic dysfunction is we are all looking for utopia and want to pay anything to read about it and find it. It’s in your genetics really. A healthy balanced diet, not orthorexia, has always been the advice. The heart foundation and the government dietician food pyramid which has been synthesised out of over five thousand pieces of research and analysed by real researches who know how to read studies and look for flaws, have concluded eggs in moderation belong in healthy balanced diet. My mother is 82, has no heart disease, no high blood pressure, no diabetes, she’s not overweight and has no arthritis. She lives independently. Doctors don’t need to see her. She is medication free. She walks for an hour a day briskly. She eats eggs. Meat. Milk. No cancer. Her siblings who smoked and drank heavily all dead. Same situation on my father’s side. He is 92. He eats eggs for breakfast every single day. He’s fit, independent and has no diseases. He’s a milk drinker. NO cancer. His siblings who smoked and drank heavily are all dead too, in their 70s. Look to the Queen of England, she’ll reach a hundred as her mother did. Her sister, who smoke and drank heavily, died young.

      Looks like eggs are indeed toxic according to IgG tests, for most people at least… I haven’t heard of a person who those test and eggs did not show up.

    I couldn’t find any scientific studies that actually show a causal effect of dairy protein on cancers, (lots of scare mongering assumptions that profit from the generation of fear of certain foods (orthorexia), but no hard evidence cited) but I did find this summary of how milk can lower cancer risk. https://onlinelibrary.wiley.com/doi/full/10.1111/1541-4337.12011

      China Study was the largest which has ever been performed.
      It showed a clear pattern of Cancer rates and types of cancer, based on the diet of the people.

      The dozens of cities and districts tested had a clear and provable pattern. It is likely the best Scientific Data ever recorded.

    Ms Peterson. I think you oversimplify the thesis of Doctor Campbell. First he goes beyond just linking animal protein to casein. He explains that Animal protein is an (efficient) protein. That is that it is very competent and potent in being a building block for cell replication. To the contrary, vegetable protein is not that efficient. There is a reason why body builders and athletes use animal protein like whey and creatine to repair muscle. It is highly efficient.

    When you introduce a carcinogen into the body, you introduce a sort of virus that starts to help replicate bad cell or over replicates. That same animal protein that’s so efficient in building positive healthy cells is not discriminatory and in this regard neither is the vegetable protein. But it’s the animal protein that will speed up the cancer growth rate.

    As far as mentioning Michael Gregor being a quack that’s unfortunate. You should consider his awesome work, and if you’re still a meat eating enthusiast, that’s fine. You mentioned auto immune diseases that you and Dr Peterson share, and he had an interesting video on yeast and it’s role in Celiac, Hidradentitis Suppurative and Arthritis. Check it out! ‘

      Hi Juan Dominguez
      I think we all need to understand how our bodies work, and what they need to work optimally, rather than becoming emotionally committed to one point of view from an ‘expert’. I invite us to explore biochemistry, even quantum biology, in order to improve our understanding of what our bodies need. This can be quite difficult if one comes across information that appears to contradict our beliefs, and we have to make a decision then whether to be open to new information, or not. My point of view is that being open to new information increases my understanding, and a better understanding is a better life.

    – The China study is the largest of its type, which has ever been performed.

    – Dr. Campbell has worked with thousands of people which used his methods and found results.

    – Not all Meat is equal – Research into the GMO’s, preservatives, antibiotics and other methods used.

    – Yes, Dairy was proven beyond a doubt by the Study to increase Cancer risk.

    – There is nothing comparable to the China Study for Gluten. In fact, it is merely an opinion to stay otherwise.

    – Your Dad is a Scientist and he follows the evidence. Let your dad look at the China Study and attempt to find an error. The Science is pure and concrete.

      I suspect you have not read any critiques of the China Study, for if you had then you would not be writing what you write. If you had read the data behind the China Study, instead of the interpretation of the data, your understanding might be different, non? I understand you are firmly committed to your point of view. Mikhaila is not firmly committed to her present point of view, she is committed to surviving and thriving and taking care of her new baby. To that end she has found a diet that allows her to do so, and has researched why that might be so, and her point of view will change as she continues to research and test her understanding with her diet/lifestyle.

    Most of the cholesterol in your body is produced by your liver and a small amount from your food.
    My gut feel is cholesterol levels go out of whack because of a lifelong sedentary lifestyle… sitting too much on your butt and not stressing your body with grinding, laborious work… symptomatic of the bureaucratic class pushing pencils/pens.

Her tactic of Ad Hominem “strawman” was comical at best, and dangerous at worst. “So what your saying is” has become an internet meme. Read your comment back, and ask yourself, if you are doing the same?

    The story of Mikalia is inspiring. I hope many people realize, the power the human body has.

    I studied the China Study in detail, and have lived on a Plant-Based lifestyle for 7 months. I do not mention my personal experience or others, as I wish to stick to the topic.

    The truth is my main aim. My research has found, there are four big problems with the SAD(Standard American Diet)

    – Sugar

    – Dairy

    – Meat

    – Eggs

    Hi Mikhaila,
    I am originally from SA and the meat is AGrade because of all the farms. Now I live in China and I find most of the meet in China is disgusting and really bad quality, especially in the rural areas. The beef here is so expensive and the only chicken you get at a restaurant is on the bone. I have had to cut out pork too. The meat here is definitely not the same as abroad and they fill it all with antibiotic, I am not arguing against your information at all, but it’s really hard to think of the exclusion diet when the meat has been making me feel ill here aswell. I am moving to a bigger city soon and will now starting to only use imported meat and see if it will help. Thanks for a great blog!

    You completely skip over the fact that the World Health Organization, as of 2015, now lists processed meats as a type 1 Carcinogenic, and red meat as a type 2A. Each 50g of either, increases risk of colon cancer by 17-18%.

    This is a silly attempt to debunk the China Study. We have more research since this book, that suggests animal proteins do in fact cause cancer, increase risk of heart disease, dementia ETC.

    Yeah, anyway, TC Campbell is a big time cherry picker. Read “The Low Carb Fraud” and make what you can from that . . . I dare you . . . Also, is production methodology taken into account with WHO’s recommendations? Do they account for fermented nitrate-free sausage in say Holland or Austria for eg vs stuff with sawdust and plant-based transfats in it from some other nation where the authorities aren’t sticklers? Do they count so called “red meat” with a balanced 1:1 ratio of Omega 3 to 6 fat molecules? Likely, the Masai prior to cheat wheat and sugar would cause their recommendation some trouble. As Gary Taubes says on these issues: why can’t they do some kind of experiment to settle it? These blanket statements are a core problem that, as the blog’s owner has mentioned cause suffering. I’ve run similar academic studies. Whether they can prove anything through the web of politics and dollar chasing is dubious at best. Regardless of dogma, this stuff won’t be mastered for another generation or two, I think, as I believe entities like the AHA or WHO are missing WAY too many factors when they make these statements (ie I don’t believe them or believe that hoofed beast or sausage is the equivalent of a baseball made of plutonium or a pack a day, sorry!)

  28. foobarbaz849 on August 4, 2018 at 8:06 pm

    So, it may not be casein that is the problem. It’s more complex than that. Turns out that there are different types of cow milk, from different breeds, that give different results.

    “A1 Vs. A2 Cows: What’s the Difference?

    The type of proteins in milk, and the proportion of various proteins, varies depending on the breed of cow and the type of animal (sheep, goat, cow, etc.).

    One of the major proteins in cow’s milk is casein, the predominant variety of which is called beta-casein. In older breeds of cows, such as Jersey, Asian and African cows (called A2 cows), the beta-casein contains an amino acid called proline.

    In newer breeds of cows like Holstein (A1 cows), however, the proline has mutated into an amino acid called histidine.

    This is important because beta-casein also contains an amino acid called BCM-7, which is a powerful opiate linked to negative health effects. Well, the proline that exists in A2 cows has a strong bond to BCM-7, which helps keep it out of the cows’ milk. The histidine in the newer A1 cows, however, has a weak hold on BCM-7, which allows it to get into the milk, and also into the people who drink the milk.

    So the theory goes that by drinking milk from A1 cows, which are the predominant cows used for dairy products in the United States, you’re exposed to BCM-7, which has been linked to:
    Neurological impairment, including autistic and schizophrenic changes
    Type 1 diabetes
    An impaired immune response
    Autoimmune disease
    Heart disease””

    There you go.

    • foobarbaz849 on August 4, 2018 at 8:08 pm

      Oh.. and raw dairy is best, in either case. Pasteurization mutates milk into a non milk product.
