About the Author
Dr. William Davis is a practicing cardiologist in Milwaukee, WI with over 25 years of experience treating patients. Dr. Davis has impressive credentials: he is a graduate of St. Louis University School of Medicine and the Ohio State University Hospitals, with additional training in advanced cardiac catheterization techniques and coronary angioplasty at the Case-Western Reserve University system in Cleveland. But along the way, Dr. Davis discovered that his heart patients had a host of other problems, including obesity, gout, GERD, IBS, celiac disease, unexplained rashes and other mystifying symptoms.
There is no one as certain of the truth as a scientist cloistered in academia, performing tests on cells in a petri dish, or a researcher running computer programs to find patterns in data. While doctors share the same training in the scientific method they also live in the real world, and they often see their patients reacting very differently than popular studies and national dietary standards describe.
Dr. Davis’ Journey
Like many other medical doctors, Dr. Davis found that low carb diets were most effective in lowering his patient’s weight and improving lipid panel results. But he is aware of the exceptions, where a person’s genetic makeup can require a different approach. It is this relentless pursuit of truth and frank discussion of exceptions that makes his Track Your Plaque / Heart Scan Blog so valuable.
Dr. Davis noted his patients had dramatic improvements in other health issues after restricting carbohydrates. After thousands of years of eating carbohydrates, why would the last 50 years see such a dramatic increase in GERD, pre-diabetes, type 2 diabetes, obesity and celiac disease? Not satisfied with simply knowing the facts, Dr. Davis sought the cause of the rapid increase.
His new book, Wheat Belly provides his answer: wheat. Yes, that golden grain, enshrined in our mythology and patriotic songs, is killing us. But humans have eaten wheat for thousands of years.
So why has this seemingly benign plant that sustained generations of humans suddenly turned on us? For one thing, it is not the same grain our forebears ground into their daily bread. Wheat naturally evolved to only a modest degree over the centuries, but it has changed dramatically in the past fifty years under the influence of agricultural scientists.
About Wheat Belly, the Book
Eminently readable, Wheat Belly is written in a conversational style, suitable for any audience. Extensive footnotes are gathered together in the References section at the end of the book, where they don’t interfere with the text. Sidebars include fascinating details; patient success stories, insights into heirloom wheat, etc.
The book is just under 300 pages, divided into three main sections:
- Wheat, The Unhealthy Whole Grain
- Wheat and its Head-to-Toe Destruction of Health
- Say Goodbye to Wheat
The first section gives the history of wheat, from the heirloom wheat mentioned in the Bible (einkorn, gathered by semi-nomadic tribes such as the Natufians as far back as 8500 BCE) to the modern, genetically altered variety created by aggressive cross breeding in the past 50 years.
Differences between the wheat of the Natufians and what we call wheat in the twenty-first century would be evident to the naked eye. Original einkorn and emmer wheat were “hulled” forms, in which the seeds clung tightly to the stem. Modern wheats are “naked” forms, in which the seeds depart from the stem more readily, a characteristic that makes threshing (separating the edible grain from the inedible chaff) easier and more efficient, determined by mutations at the Q and Tg (tenacious glume) genes . . . But other differences are even more obvious.
Note: the ellipsis indicates I removed a reference to a study mentioned previously in the text.
The differences in modern and ancient wheat is more than “skin deep”. On the glycemic index, whole wheat bread exceeds table sugar, scoring 72 versus sugar’s 59 on the scale. Because the carbohydrates in modern wheat are so easily digestible, eating whole grain results in the same blood sugar impact as an equivalent amount of highly processed flour. White bread, with less of the whole wheat grain, comes in at 70. A Snickers candy bar comes in lower, with a glycemic index of 41.
Interestingly, Dr. Davis’ self-experiment with baking bread showed his own blood sugar rise from 84 mg/dl to 110 mg/dl with 4 ounces of bread made with einkorn wheat. He also baked bread with modern wheat, keeping all other ingredients the same, and consumed the same four ounces. His blood sugar shot up from 84 mg/dl to 167 mg/dl.
Dr. Davis provides more detail on the genetic differences that carry unknown effects including the increase in chromosomes from 14 to 42.
Wheat and Modern Health
After establishing why modern wheat is different, Dr. Davis lists the health impact this new, genetically modified food product has introduced. First among impacts is the addictive property of modern wheat, and how it stimulates hunger. Then an extensive treatment of each health condition:
- Celiac Disease
- Diabetes and Insulin Resistance
- Acid Reflux and Stomach pH
- Cataracts, Wrinkles, and the aging process
- Heart Disease
- Wheat’s effect on the brain
- Acne, rashes and other skin problems
Each chapter in this section includes footnotes to studies, as well as examples from Dr. Davis’ practice. Each topic is fully developed, and written in an easy-to-read style without excessive medical terminology (Dr. Davis explains the medical terms he does use).
Practical Application of Wheat Elimination
In the third section, Dr. Davis deconstructs the modern “eat healthy whole grains” advice. If you eliminate all wheat, do you end up with vitamin and mineral deficiency? Not if you follow his basic (and very easy) guidelines. Dr. Davis comments on the true effect of eliminating wheat:
Let me describe a typical person with wheat deficiency: slender, flat tummy, low triglycerides, high HDL (“good”) cholesterol, normal blood sugar, normal blood pressure, high energy, good sleep, normal bowel function.
The book devotes 37 pages to Dr. Davis’ simple method for eliminating wheat and replacing it with unlimited vegetables, raw nuts, grass fed beef, chicken and fish, and other whole, nutritious foods. He departs from the usual low carb / paleo prescription to warn about eating too much processed meat, with its chemical soup of seasoning, nitrates and other potentially harmful chemicals. And, a special note is made regarding the proliferation of “gluten free” products that substitute fructose and “chemical soup” in place of wheat that may still pose health risks. Instead, Dr. Davis provides a variety of great wheat free recipes to provide an insight into managing a diet without wheat, introducing wonderful variety and enjoying the journey.
I am by nature a skeptical person, but my personal experience with low carb dieting led me to believe, long before I discovered Dr. Davis’ blog, that I may have a “hidden” wheat allergy. After suffering from painful GERD for over a decade, I noted a rapid decrease in symptoms when I started a low carb diet. My GERD does not return when I have the occasional indulgence of ice cream while on a cruise, but comes back with a vengeance when I consume wheat products. My personal experience is not scientific proof, of course, any more than the sidebar stories of dramatic cures are scientific proof in Wheat Belly.
I suspect I will still eat bacon and other processed meats, and I don’t share the enthusiasm for grass fed organic beef and free range chickens and eggs. But those quibbles aside, Dr. Davis’ clinical experience, supported by his scientific research as revealed in 16 pages of references, make a powerful argument that I find hard to refute.
It is easy to do your own experiment; there are no adverse health effects to eliminating wheat and eating according to Dr. Davis’ easy prescription. Two weeks is usually sufficient to notice differences in some conditions. I can heartily recommend Wheat Belly as a practical guide to seeing if you also have a “hidden” wheat allergy.
