      Thanks for this thought-provoking link.

      I feel that Dr. Eades’ argument was weak in two major ways, namely:

      #1: The China study was not interpreted with respect to the totality of evidence in favor of a whole foods plant based diet; Of course, no single health science study, even randomized-control trials, provides full-proof scientific evidence. Expert interpretation is valuable since it provides a bird’s eye view.

      #2: A plausible alternative hypothesis was not provided that could explain the correlations found by Campbell and co-workers. These Atkins’ followers seem to have a one-track mind, always blaming refined carbohydrates for everything, with little data to support their position; They never apply the same standard of criticism to their own work as to that of the pro-veg movement.

      Therefore, I find it hard to take Dr. Eades and other Atkins’ followers seriously!

      But, I read ‘The China study’ and think that Dr. Cambell’s claim that animal protein promotes cancer is, at this stage, more of a hypothesis than a medical fact.

  • Mike Quinoa


    Dr. Eades, who wrote the analysis, is a proponent of a high animal protein diet. It makes perfect sense he would find fault with the China Study—I would expect no less. Are there any critical reviews of the China Study made by a detached third-party that you are aware of?

    The real-world experiences of Dr. Caldwell Esselstyn and Dr. Dean Ornish in preventing and reversing heart disease, and the methods by which their results were obtained, cannot be refuted. Nor can the evidence found in the PDAY study, which demonstated conclusively the atherosclerotic-producing nature of the SAD.

    The criticisms against Dr. Campbell’s “The China Study” book don’t hold up very well, if one has actually read the book.

    However, I can see how those criticisms might convince someone to not bother reading the book at all. I think that this is the main purpose of these criticisms, to bias people against Dr. Campbell’s book to the point where they don’t read it and therefore can’t be persuaded by it.

  • Liviu Deacu

    I’m also highly interested to find out the truth about the value of the China study and who has the interest in blaming its value.

  • Meha

    Mike Quinoa, do you know Jack Norris and Virginia Messina? They recommend a vegan diet, but are against the Campbell’s approach. It’s the same speech: correlation is not causation, RCT is the golden standart, etc.

  • Mike Quinoa

    Hi Meha,

    Yes, I know of Jack Norris and Virginia Messina. I appreciate the fact they never sugarcoat any contrary scientific evidence re: the vegan diet. They want the healthiest possible vegans out there. To me, a radiantly-healthy vegan is the best advert for a plant-based diet.

    There are a number of issues with Cambell’s (and others such as Ornish) selective interpretation and manipulation of the China Study data. No other study has replicated the findings of the China Study and multiple academics and scientists have handily provided alternative ways of interpreting the data. Oh and three of the five sources cited above are just different publications of the same China Study data.

    Please read the following articles for proper, critical analyses of the
    Study and its misleading use in promising prevention and cures that
    don’t/can’t/won’t deliver.

    Please no anecdotal evidence if you reply to this post – here’s why:

    Eat with moderation. Exercise regularly. Don’t smoke. Limit alcohol. And hope you have decent genes. Now those are replicated, falsifiable scientific theories of maintaining good health.

      SAD diet…cholesterol 239, plant based diet (NO STATINS), Cholesterol 168…that’s NOT anecdotal you jerk..that’s a fact. And thousands and thousands of plant based eaters get the same results.

      • robert

        My personal China study: SAD diet was 320 total cholesterol, and plant-based is now 158 w/o meds.

  • Karna

    Are there valid criticisms of T Colin Campbell’s book The China Study? I have become plant based recently and am looking for scientifically based information to share with family. I want to make sure I am using credible information.

    • Don Forrester MD

      The China Study was an ecological research study that was very unique in its design for instance in the communities tested they pooled urine and blood samples. Like all scientific studies they can be criticized for their strengths and weaknesses. The conclusions are consistent with the good scientific research and what we currently know about our anatomy and physiology (we are hind-gut fermenting herbivores adapted to better consume starches). The best diet is a variety of whole plant based foods based on adequate starches to insure adequate glucose intake to meet our caloric needs… also insuring an adequate intake of Vit B12. The shifting of the paradigm is occurring but folks hang onto old beliefs and change at different speeds. Critiques are usually well meaning but can reflect vested self interests… pushing supplements like we in medicine sometimes push pills. The best in depth demonstration of this phenomenon is the issue of screening mammography. The science is clear at this point… no screening mammograms for women at any age. The best information on this contained in the Nordic Cochrane Center’s 2012 pamphlet and Dr. Peter Gotzsche’s book which dissects out all the studies and the misleading statistics. At this time as a Family Medicine physician I can no longer recommend them. It saves me some time but I takes a while to explain to my patients the reasons since we have been advocating them for so long. Interacting with others who have not made the shift to the best diet is difficult. The best discussion I have seen is by Dr. Doug Lisle’s video, Getting Along without Going Along. He is a psychologist who works at the McDougall clinic and the video is available through Dr. McDougall’s website. Congratulations on becoming plant based I think you will find it a rewarding and healthful journey.

      Karna, please read “The Starch Solution”, Dr. John McDougall. All info is referenced. Weigh yourself. Have your blood tested. Go to the market, buy whole oatmeal for your first breakfast. Buy starches for energy and to maintain a healthy weight. Buy the greens, and other vegetables for your vitamins, and minerals. Get some sun, and a bottle of B-12. Throw out all meat, dairy, eggs, processed food, and oil. Eat all you want to, and as often as you want to. It is a simple, enjoyable, healthy plan.
      A month later weigh. Look in the mirror. Get your blood tested. If you like the results. Stay with it. If not, continue to read commentaries for health information. Even an ol’ blind sow will find an acorn.
      When reading, or watching on, “The Starch Solution”, refrain from reading commentaries. Only a distraction.
      I am 80. Doctors were killing my skinny ass. AAA surgery led to seven years of uncontrollable, high blood pressure while taking three meds for it. Now! On McDougall’s Program, I lost forty lbs. I threw away the meds. Blood tests are excellent. Sleep apnea is gone, Esophageal reflux is gone. I walk three miles per day. I have more energy than at age thirty. My girlfriend is thirty. :-) I started “The McDougall Program 12/4/2012. I love it!
      I will never change back to meat except in a starvation emergency.
      Good luck, and I thank Dr. Greger. He is a great human.

    I’m pretty convinced about a plant based diet for optimal health. However, this in-depth critique of the China Study leaves me a bit uneasy about the rationale of the evaluation of the data. I would appreciate a response from you, since you seem to be somewhat unbiased in your data analysis, and still fully support a plant based diet.

    Thanks a lot!

  • Luc

    I was in Guizhou about 5 years ago. To 镇远(zhenyuan) means far-away-place , if my translation is right. The hotpot is their favorite food there and I can assure you , when I met up with my chinese frieds there ( not a vegetarian at that time ) we all ate a lot of meat.
    An anecdote : My vegetarian friend who also travels to China often was given the chinese nickname meaning “rabbit” haha

    Can congestive heart failure be reversed? if so how? How can you strengthen the heart to get better results on hyour echo-cardio gram?

  • Michele

    I have a question: some studies suggest that the ratio of Omega 3 to saturated fats in the diet is what prevent heart attacks and not necessarily cholesterol levels and they cite the diets of Eskimos. Any studies to confirm or refute this?
