I had no idea what to expect from Wheat Belly, the new book by Dr. William Davis. Several of you had asked me about it so I picked it up, not knowing much about the author or its content.
Davis is apparently a medical doctor who treats patients for heart disease and other ailments using a wheat-free diet. Though this isn’t particularly revolutionary I was immediately intrigued by the first chapter of Wheat Belly, which gives a detailed explanation of how modern wheat is different both physically and genetically from the wheat “our grandparents grew up eating.”
He explains that selective breeding and genetic manipulation to increase wheat yield have dramatically changed the chromosome number of modern wheat compared to earlier versions grown before the 1950s. This, he claims, fundamentally changed the molecular properties of wheat and we are supposedly not yet adapted to the new product.
I haven’t gone through all the plant biology to determine if any of these claims hold water, but the premise is fascinating. If modern wheat were really a primary cause of the health issues plaguing Western society, not only would gluten be off the hook (once I started reading I thought this was going to be another gluten-free diet book), but all other grains would be back on the table, even older versions of wheat.
Had Wheat Belly gone on to further explore the differences between modern and traditional wheat and, most importantly, how they affect people differently, then this could have been a groundbreaking book. Unfortunately, that isn’t what this book is really about.
Davis doesn’t present a shred of evidence that modern wheat has a worse (or even different) impact on human health than pre-industrial wheat. The only anecdotal case he makes is that he personally found a farmer who grows traditional wheat, made a loaf of bread, ate it himself and seemed to be fine. This is not science.
Instead the rest of the book focuses on how his patients have benefited from removing wheat (presumably modern) from their diets, a premise that is much easier to swallow but brings us right back to Dr. Atkins. Wheat is the most abundant refined carbohydrate, and refined carbohydrates are almost certainly the biggest contributor to human health problems on the planet. Is it any wonder that eliminating the major one—not to mention the ingredient that is most often paired with sugar—would make people feel better?
When push comes to shove, the bulk of Davis’ argument is not about modern wheat at all, but about the Glycemic Index (GI) of foods (he’s sure to point out that the GI of wheat is even higher than sugar). His prescription is not just wheat elimination or even gluten elimination, but removal of all grains, sugars and starchy foods like potatoes and even beans.
Haven’t I heard this somewhere before?
To his credit, Davis promotes a relatively healthy diet. He discourages the use of gluten-free flour substitutes because for the most part they are just another form of unhealthy food. Though these ingredients can obviously play a role in the lives of people with serious gluten sensitivities, I agree that they do not qualify as health food just because they do not contain gluten. But extrapolating from processed carbohydrates to nutritious whole foods like beans and potatoes that most of us can eat without increasing risk of disease or obesity is less than helpful.
But all my criticisms aside, I think there are some valuable messages in Wheat Belly worth considering. Gluten (and maybe just modern wheat, who knows) is known to be one of the most inflammatory substances consumed by humans and many people would likely benefit from cutting it out. Davis recommends eliminating wheat for 4-8 weeks to see if there is an improvement in symptoms.
If you regularly struggle with any of the following issues, a temporary gluten-free experiment may be worth it for you:
- irritable bowel syndrome
- autoimmune problems
- attention deficit disorder
- hair loss
- bone loss
And there are probably many more. The nice thing is that while eliminating gluten for 4-8 weeks does take some effort, it is still a relatively simple, non-invasive way to troubleshoot health problems and potentially improve your life dramatically. If nothing improves, you can always go back to your bagels and Cheerios. It is important to keep in mind though, that many symptoms require an extended period without gluten before improvement is seen.
To summarize, I really wish Davis had done a better job of convincing me that it is modern wheat and not processed foods in general that is particularly problematic in the Western diet. From that perspective, this book is just another Atkins diet with a better title. That said, I do think Davis does a good job of illustrating how many ways patients could benefit from a temporary wheat elimination. The prescription is easy and harmless, and definitely worth trying if you have health problems you and your doctor can’t seem to solve.
