The China Study by T. Colin Campbell & Thomas M. Campbell Review: A Landmark, Debate-Sparking Nutrition Argument
First published in 2005 and expanded in a 2016 revised edition from BenBella Books, The China Study by T. Colin Campbell and Thomas M. Campbell is one of America's best-selling books about nutrition, making a forceful case that a whole-food, plant-based diet can help people escape, reduce, or reverse a wide range of chronic diseases — a claim that has driven both widespread adoption and sustained scientific debate.
LuvemBooks Verdict
Best for
Readers already curious about or committed to whole-food, plant-based eating who want a thorough, epidemiologically grounded argument — complete with mechanistic reasoning and a critique of reductionist nutrition science — for eliminating animal products from their diet.
Worth it if
Worth reading if you want a strongly argued, data-informed case for a whole-food, plant-based dietary philosophy, and you're comfortable engaging with a text that presents its conclusions with confidence rather than academic tentativeness.
Skip if
Skip it if you come from a research or epidemiology background and need careful qualification around confounding variables and the limits of correlational population data — the authors' tone is more advocacy-driven than cautiously scientific, and the sweeping conclusions extend well beyond what the underlying China–Cornell–Oxford Project directly supports.
What readers & critics say
According to Wikipedia, the book had sold over one million copies as of October 2013, making it one of America's best-selling books about nutrition, though Wikipedia also notes it is only "loosely based" on the China–Cornell–Oxford Project — a characterisation that signals the breadth of conclusions the authors draw beyond that single study.

What Works & What Doesn't
What Works
- One of America's best-selling books about nutrition, with over one million copies sold as of October 2013 — a testament to its broad and lasting influence
- Anchors its argument in the large-scale China–Cornell–Oxford Project, a 20-year study spanning 65 counties in China
- Advances a coherent methodological critique of reductionist nutrition science, arguing for the study of whole dietary patterns rather than isolated nutrients
- Covers a wide range of chronic diseases — including coronary heart disease, diabetes, breast cancer, prostate cancer, and bowel cancer — giving the plant-based argument wide scope
- Available in a 2016 revised and expanded edition, updated from the original 2005 publication, and translated into over a dozen languages
What Doesn't
- The book is described as only 'loosely based' on the China–Cornell–Oxford Project, meaning its sweeping conclusions extend well beyond what that single study directly supports
- The authors state their dietary conclusions with a high degree of certainty — readers expecting careful qualification of correlational epidemiological data may find the tone more advocacy-driven than academically cautious
The book has earned its place as one of America's best-selling books about nutrition — and its argument is direct enough to explain why.
What the Book Actually Argues
The China Study is a work of popular nutrition science, not a memoir or cookbook. Its central argument is that consuming animal products — including beef, pork, poultry, fish, eggs, cheese, and milk — is causally linked to chronic illnesses such as coronary heart disease, diabetes, breast cancer, prostate cancer, and bowel cancer. The Campbells conclude that people who eat a predominantly whole-food, vegan diet, while also reducing processed foods and refined carbohydrates, will escape, reduce, or reverse the development of those diseases. The book puts that position in uncompromising terms: as Wikipedia's summary of the text notes, the authors write that "eating foods that contain any cholesterol above 0 mg is unhealthy." The book also recommends sunshine exposure or vitamin D supplements, and vitamin B12 supplementation for those who eliminate animal products entirely. It explicitly criticises low-carb approaches such as the Atkins diet, pushing back against the reduction of carbohydrates as a dietary goal.
“eating foods that contain any cholesterol above 0 mg is unhealthy.”
The Evidentiary Backbone — and Its Acknowledged Limits
The book grounds its case in the China–Cornell–Oxford Project, a 20-year epidemiological study that examined mortality rates from cancer and other chronic diseases recorded in 65 counties in China from 1973 to 1975, then correlated that data with dietary surveys and blood work gathered from 100 people per county in 1983–84. The scope of that underlying dataset is genuinely substantial. However, as Wikipedia's reception summary makes plain, the book is described as only "loosely based" on that project — a characterisation worth holding in mind when evaluating the breadth of conclusions the authors draw from it. Readers approaching the book as a direct report of a single definitive study should understand that the Campbells use the China–Cornell–Oxford Project as a launching point for a wider nutritional argument, not as its sole and exhaustive foundation.
A Methodological Stance That Sets It Apart
One of the book's more intellectually distinctive contributions is its critique of reductionism in nutritional science. Rather than isolating individual nutrients and assigning blame to each in turn, the Campbells argue for studying whole patterns of nutrition and the interactions between nutrients. This positions The China Study against much of the conventional academic and popular nutrition literature, which has tended to focus on single compounds — saturated fat, dietary cholesterol, specific vitamins — rather than dietary patterns as integrated wholes. Whether or not readers accept every conclusion, this framing represents a coherent and substantive methodological argument that distinguishes the book from simpler diet titles.
Cultural Reach and Commercial Scale
By October 2013, The China Study had sold over one million copies, a threshold that, as Wikipedia's entry records, made it one of America's best-selling books about nutrition at the time. It has since been translated into more than a dozen languages, including German, Polish, Czech, Slovenian, Italian, Chinese, Japanese, Korean, Romanian, Swedish, and Urdu — a global footprint that reflects both the universality of the dietary questions it raises and the appetite among international readers for population-level nutritional evidence. The 2016 revised and expanded edition, published by BenBella Books, updated the original 2005 text, making this the current standard version for readers coming to the book afresh. That longevity across two decades of publication is itself a meaningful data point about the book's hold on the popular nutrition conversation.
Who Will Gain Most — and Who May Push Back
Readers drawn to whole-food, plant-based eating — whether already committed or newly curious — will find The China Study a thorough and strongly argued resource, one that provides an epidemiological and mechanistic rationale for dietary choices they may already be exploring. Those who arrive from a background in nutritional epidemiology or research methodology, however, are likely to press harder on the gap between correlational population data and the causal conclusions the Campbells state with confidence. The book does not position itself as a tentative hypothesis; it presents its findings as settled, and readers who want more qualification around confounding variables or alternative interpretations of the underlying data may find themselves wanting more nuance than the text provides. The China Study is best understood as an impassioned, data-informed argument for a specific dietary philosophy — one that has demonstrably changed how millions of people eat, and one that continues to generate genuine scientific discussion about the strength of its evidence base.
Frequently Asked Questions
is The China Study: The Most Comprehensive Study of Nutrition Ever Conducted and the Startling Implications for Diet, Weight Loss, and Long-Term Health by T. Colin Campbell and Thomas M. Campbell worth reading
It depends on what you're looking for. If you're curious about whole-food, plant-based eating, the review calls it 'a thorough and strongly argued resource' that provides both epidemiological and mechanistic reasons for that dietary approach. If you have a background in research methodology, though, you may find yourself wanting more nuance — the review notes the book presents its conclusions as settled rather than tentative, and doesn't offer much qualification around confounding variables or alternative interpretations of the data.
What is this book actually about
It's a popular nutrition science book that argues consuming animal products — including beef, pork, poultry, fish, eggs, cheese, and milk — is causally linked to chronic diseases like coronary heart disease, diabetes, breast cancer, prostate cancer, and bowel cancer. T. Colin Campbell and Thomas M. Campbell conclude that a predominantly whole-food, vegan diet, combined with reduced processed foods and refined carbohydrates, can help people escape, reduce, or even reverse those diseases. The book also takes direct aim at low-carb approaches like the Atkins diet.
Is the science in this book actually legit
The underlying dataset — the China–Cornell–Oxford Project, a 20-year epidemiological study across 65 counties in China — is described in the review as 'genuinely substantial.' However, the review also flags that the book is described as only 'loosely based' on that project, meaning the Campbells use it as a launching point for a much broader nutritional argument rather than a direct report of a single definitive study. Readers with a nutritional epidemiology background are likely to push back on the leap from correlational population data to the causal conclusions stated with such confidence.
Does this book say you can never eat meat or animal products
The book's position is pretty uncompromising — the review notes the authors write that 'eating foods that contain any cholesterol above 0 mg is unhealthy,' which effectively rules out all animal products. That said, the Campbells do recommend vitamin B12 supplementation for those who eliminate animal products entirely, and sunshine exposure or vitamin D supplements, so the book does acknowledge some practical adjustments needed for a fully vegan diet.
Is this book good for someone who's already eating plant-based
Yes, the review specifically identifies people 'already committed or newly curious' about whole-food, plant-based eating as the audience most likely to get value from the book. It offers a detailed epidemiological and mechanistic rationale for choices they may already be making, which many plant-based readers find validating and useful. It's a work of popular nutrition science rather than a cookbook, so it's more about the 'why' than the 'how.'
What makes this book different from other diet books
One of its more distinctive contributions, according to the review, is its critique of reductionism in nutritional science — rather than blaming individual nutrients like saturated fat or dietary cholesterol, the Campbells argue for studying whole dietary patterns and the interactions between nutrients. The review says this positions the book against much of the conventional academic and popular nutrition literature and represents 'a coherent and substantive methodological argument that distinguishes the book from simpler diet titles.' It's that framing, not just the vegan conclusion, that has kept it in serious nutritional conversation for two decades.
How popular is this book and is it still relevant
By October 2013 it had already sold over one million copies, making it one of America's best-selling books about nutrition at that time, and it has since been translated into more than a dozen languages including German, Japanese, Korean, Urdu, and Swedish. The 2016 revised and expanded edition from BenBella Books updated the original 2005 text, meaning it's been actively maintained for nearly two decades. The review notes it 'continues to generate genuine scientific discussion about the strength of its evidence base,' so it's still very much part of the conversation.
