What we eat is a leading factor in our health and quality of life. Research has proven that a plant-based diet can prevent and sometimes reverse chronic diseases like heart disease, type 2 diabetes, and cancer.
Yet this message has been ignored, distorted, or suppressed by people and organizations with a vested interest in the status quo.
In a compelling new analysis, Dr. T. Colin Campbell, coauthor of The China Study and author of the New York Times bestselling follow-up, Whole, brings to light a series of first-hand experiences that starkly demonstrate how corporate influence in academia, government and the media determines—and sometimes actively suppresses—public access to nutrition research.
Providing an eye-opening look behind the scenes of nutrition policy, Dr. Campbell recounts the story of his life and research, and then tells eight riveting stories in The Whole Truth about instances in which vital information was misrepresented or concealed, A national nutrition “supreme court” quietly organized by industry-affiliated scientists to control public messaging—and the attempt to expel Dr. Campbell from his own professional society when he challenged it. Manipulation of the U.S. Dietary Guidelines to permit consumption of animal protein at levels posing a higher risk of deadly chronic diseases. A research paper on the impact of nutrition on immunity—vital information for the COVID-19 pandemic—that was rejected from academic journals without professional review. An infant-feeding scandal in which a heavily marketed commercial product displaced breastfeeding—leading to widespread infant malnutrition and deaths around the world. Coauthor Nelson Campbell, a filmmaker, health advocate, and Dr. Campbell's son, broadens the lens in the book’s third part, examining why the plant-based movement has stalled and how it can be renewed through more effective messaging and a grassroots strategy to empower people everywhere to participate in building a healthier world. His suggested approach is provocative, inspiring and hopeful. Together, he and his father have authored a book that will infuse new energy into the plant-based movement.

The study was described by The New York Times as "the Grand Prix of epidemiology."
Thank you, NetGalley, for an ALC of The Whole Truth!
Having previously done a deep dive into “How Not to Die,” a book also promoting a whole food plant-based diet by Dr. Michael Greger, I was interested to dive into “The Whole Truth” and learn more about Dr. Campbell’s research. I was admittedly a little skeptical based on my previous experience because I found that many of Greger’s cited works actually shared that a combination of lifestyle changes (including diet) produced the changes he attributed to solely eating a plant-based diet, but I wanted to hear Campbell’s arguments as this is a topic I am very intrigued by.
First, I want to applaud Campbell’s tenacity to continue to write, publish, and defend his work as a man in his 90s. It is clear that he has been walking-the-walk and I always appreciate hearing a scientist talk about their passions. It is evident he cares deeply about community health and simply wishes to help people live happier, healthier lives. His passion is extremely evident in his writing and I think that aided this book in capturing and retaining my interest instead of reading like a textbook.
The only point that stood out to me in this book as significantly lacking support was Campbell’s claim that he and his wife only experienced mild COVID symptoms after electing not to get the vaccine due to their plant-based diets. It was well known during the height of the pandemic that healthier individuals with stronger immune systems would be less likely to experience life-threatening COVID symptoms, so I don’t think their experience can simply be tied to diet alone.
I appreciate that this book points out some major issues related to lobbying and the ability of corporations to buy their way into our public health recommendations. When teaching nutrition and reviewing the “Guidelines for Healthy Americans,” I have always pointed out to my students that added sugars are completely unnecessary within our diets and do not benefit us, however, there is a recommended allowable amount of added sugar included in our dietary guidelines. It resonated with me to hear Dr. Campbell talk passionately about how the intermingling of corporations in our health recommendations is a detriment to the American populous.
I did find it interesting that Dr. Campbell mentioned that publishers were adamant that he share his findings as a cookbook with recipes for a WFPB diet. Personally, I would’ve really appreciated that cookbook!
The final portion of this book where Dr. Campbell’s son takes the reins was a little disappointing to me. I didn’t feel that this section resonated with me as much nor did I have many takeaways about the future of this work like I thought I might.
Overall, when considering this work strictly as a book I would say that I enjoyed the content, pacing, and tone. It read exceptionally well for a scientific work. Regarding the actual science within the book, I did find it difficult to validate the claims that felt unsupported or far fetched since I was listening to the audiobook and did not have a bibliography of referenced literature to review. I would recommend this book to anyone interested in learning more about the WFPB diet.
Thank you NetGalley and Brilliance Publishing Audio for giving me access to this audiobook ARC in exchange for my honest review. Ooooh this is a doozy to review! Dr. Campbell, at 91 years old, continues to advocate for a less-popular means of being healthy. Son to an Irish immigrant farmer, Campbell grew up on a farm and one may say, is predisposed to promote a plant-based diet. He loves animals and understands the science behind plant-based nutrition. It would be easy to write him off as a bias perspective; not wrong but definitely coming from a certain angle. To do that though, would be to ignore the science, research, studies, and years (decades) of dedication to addressing health issues, namely cancer. With funding from NIH grants, resources from Columbia and other universities, and collaborations with several different entities and countries, Campbell has put his heart into this work. And this book speaks to that tireless toiling. The start of the book reads very much like a defense of his work and research. I wish he didn’t feel the need to do that but also understand the inclination. I am really interested in the science and what the science says so I would have enjoyed even more of that. Instead, this is a bit of a chronology of all of the times Campbell has told us the same thing, only to be ignored. Does this book make me want to completely change my way of eating? No, not exactly. But it does a good job of presenting options and explaining how capitalist pressures have led to a singular narrative around wellness. I especially appreciated his examination of the baby formula business. While I fully support that a “fed baby is the best baby,” science supports “breast is best.” However, companies did significant marketing to promote a formula-preferred society. Again, there should be no judgement in how someone feeds their baby AND someone should not choose formula just because of a marketing machine tells them to. Parenting (mothering specifically) is hard enough without societal pressures and body control conversations. I appreciated Campbell’s sensitivity around this example. The end of the book goes an interesting direction with some religious connections. He doesn’t push an agenda here but mentions the inspiration he takes and encourages readers to see the broader picture, the interconnectedness, the role nature plays in our lives. I agree with all of that. I’m glad I read this as a way to learn other perspectives and be introduced to some great resources and documentary films I want to check out. The production quality of this was good. I think narrators have to be extra good to keep interest in a non-fiction book. And I really enjoy non-fiction; but I don’t want someone reading a textbook to me. The pacing was good, chapter transitions were clear, and I stayed fully engaged in this book.
Excellent! At 92, TCC has published his best book yet. Although I’ve known him personally and professionally, there was much about his personal story I did not know and very much enjoyed learning.
He also does an impeccable job detailing the corruption of the health and wellness space, the food industry, the insurance indirty err industry, big pharma, celeb dr and influencers, etc. It’s dark but important information you deserve to know and we all need to bring to light.
Perhaps my favorite part was the third section by his son, who departs from SOS free, fat free, raw til x, and other nutritarian type approaches.
I have long maintained this position myself and been attacked for it and then attacked further when I criticized people who promote dietary extremism and reductionist viewpoints (eg focusing on eating certain foods daily and strictness).
While I’m not a researcher or a doctor I do live in the real world with real people. I have also been around the healthiest populations and they definitely aren’t clocking how much cumin and green tea they’re consuming or coming up with checklists to make sure they consumed a pound of greens, mushrooms, or a Brazil nut daily.
For longtime followers of the WFPBNO movement it might be jarring to hear a founding leader say a little salt or sugar is fine to make things enjoyable and that whole fats have multitude of benefits, most especially that they make meals more desirable and the plant based diet more appealing and realistic.
I can’t agree more. As I have aged I have found I feel better with some fats in my diet, particularly seeds. Eating these as a main protein source (along with greens) and displacing beans has also helped my autoimmune diseases stay under control.
Most shocking to me though was after nearly two decades of feeling like a hungry hungry hippo I finally felt satiated.
I also consume an alarming amount of salt these days, as a steady supply of electrolytes helps with my medical condition. (All of which are hereditary and not diet based)
I’ve often wondered how I would be attacked for being less than the perfection expected of a plant based leader (albeit a long retired one) if I came out saying I eat fats! I eat salt! I even consume coconut! (Gasp) … and now I guess we will find out 8-)
ARC was provided by the publisher via Netgalley in exchange for an honest review.
This book was very much outside my usual genres, but I felt compelled to request it because this topic is personally important to me. I’ve been a vegetarian for 15+ years and have slowly been moving more toward a plant-based lifestyle over the last few years, especially after being diagnosed with a chronic illness. Recently, I asked a specialist whether diet changes could help alleviate some symptoms, and she honestly told me she hadn’t been trained enough in nutrition to discuss it in depth. That conversation stuck with me, so this book came at the right time for me.
I’m really glad I picked it up. I especially appreciated the story-based format. Dr. Campbell is 92 years old, and at times it genuinely felt like sitting down with a grandparent listening to life stories and reflections from decades of work and experience. The audiobook format worked especially well for that.
What I appreciated most was Dr. Campbell’s willingness to openly admit when his previous beliefs were wrong. He was raised believing animal protein was nutritionally superior, but when his research started pointing him in another direction, he followed the evidence instead of downplaying it. That level of intellectual honesty feels increasingly rare.
The book did get somewhat repetitive at times, especially between Dr. Campbell’s sections and Nelson’s sections, but I still found the overall message compelling and approachable. There was enough scientific detail to establish credibility without becoming overwhelming or unreadable.
I also appreciated the discussion around how intimidating a whole-food plant-based lifestyle can feel for people. One thing I’ve always believed is that perfection shouldn’t be the enemy of progress. Not everyone has the resources, time, or ability to completely overhaul their diet overnight, and even small changes matter.
The audiobook narrator was also excellent for nonfiction — clear, steady, and never overly performative.
★★★★★ Part 1 & 2 I read The China Study many years ago and I was excited to see that T. Colin Campbell was releasing a new book. The fact that he is 91 and healthy enough to write a book should be a ringing endorsement for a WFPB diet alone. He touches on his research first, then he shares some of his personal experiences with organizations who have misled the public on matters of health. I appreciated the story-like format of this book and while some of the information is frustrating to hear, I found it hard to put down. If you read or watched anything regarding the Teflon scandal, the Johnson and Johnson scandal, or any other corporate/governmental cover ups, then this book might be of particular interest to you.
★★★ Part 3 The introduction stated that the authors didn't want to leave us angry or hopeless so this section would focus on change and actionable steps. I was most excited for this section, unfortunately, I didn't leave this book feeling empowered. While I think the wider population needs to know the government's negative role in our health and food choices, I also think the people who pick up this book need more hope and helpful suggestions coming from the leading experts in this field. Reading that the movement "has flatlined and become somewhat irrelevant" is not at all inspiring. I like the idea Nelson Campbell presents about connecting outside of the digital world so that the message cannot be manipulated, but instead of encouraging the average person to host neighborhood gatherings or to share WFPB recipes and successes with their community, he leaves off on his hope that someone "with leadership skills and access to capital" can pick up where he left off. Yikes, not exactly the motivational sendoff I was hoping for.
Know what you are getting. This is roughly an autobiography for the career of T. Colin Campbell and how his research did not make the impact that it should have. The blame falls on all sorts of people and organizations. It is a somewhat short read/listen coming in at 207 pages or a little over 4 hours if listening to the audiobook at 1.0x.
The initial 2 sections were enjoyable and did encourage me to take another step towards a whole food plant-based diet. The arguments for a plant-based diet were good without any fearmongering or pandering. His ability to convey the seriousness of the need for a change in the American diet and the conflicts of interest in research funding and lobbying was well worded and helped drive home the challenges in his career. It was at times difficult to follow the timeline and a simple career timeline in the PDF may have really helped with this.
The last section was a huge transition as he passed the book off to his son. Whereas the initial 2 sections felt like a David vs Goliath story, the third was more of a woe is me saga. Unfortunately, human psychology is such that we remember the ending more than the rest of a story or experience and this was a huge let down, almost downplaying or reducing the urgency for change.
The narration was good with the optimal speed for me at 1.5x. Good inflection and transition between chapters.
Writing 4/5 for the first 2 parts, 2/5 3rd part Narration 4/5 at 1.5x Overall 3/5 due to the huge let down at the end. It would have been a solid 4/5 or better if there was no part 3.
This is a succinct but flawed volume. The author, famous for the China Study, is a leader in nutrition and advocate for plant-based diets. No question: he and his colleagues have done a lot of fantastic, counternarrative work around nutrition. Yet, he talks like a conspiracy theorist, presents superficial evidence we're just supposed to believe, and makes grandiose claims he should know better than to make without rigorous empirical data to back them up (like plant-based diets being a good alternative to COVID-19 vaccines ... yup, he's apparently some variety of anti-vaxxer).
The main premise isn't really shocking if you've been paying attention to the decline of America and the rest of the world under capitalism. Got research that might ruffle some mighty, precious, purse-holding feathers and facing heat? Join the club!
I dunno. I was expecting more and better. A scientist who apparently understands self-bias and cares about doing good research, and yet falling prey to all the failings of weaker minds. Why can't we have it all?
David de Vries does a great job with the narration. A very good voice fit.
Thank you to NetGalley and Brilliance Publishing | Brilliance Audio for the advance copy of the audiobook.
Thank you NetGalley and the publisher for the audio.
This book was interesting!
I DO NOT currently eat a plant based diet but I have in the past and anecdotally, based on my own experience of eating a vegan whole food diet for 2 years, I am inclined to say there is probably a lot to this man’s life work and study of nutrition and I think this is some great inspiration for people looking for a more sustainable healthy diet based on nutritional science and eating whole plant foods.
The author, T. Colin Campbell, is currently 92 years old in 2026. He’s an American biochemist and has devoted his life to studying nutrition on long term health. This book almost reads like a defense of his career and a possible last chance for him to get his life’s work, findings, and career documented.
These type of books always a hit a nerve with people because meat and dairy are such a huge part of our culture. It does make you wonder what life would be like if they weren’t. I recommend this book to anyone willing to hear it out and looking for inspiration to eat their fruits and veggies. Anyway, off to eat some greens and berries!
