Disease Proof by Dr. David Katz
Imagine if a pharmaceutical company introduced a drug that promised to cut your chances of contracting all diseases (including diabetes, cancer, and heart disease) by at least 80%? I imagine you would immediately have four questions: How much does it cost? What are the side effects? How can I get a prescription? And, How can I invest in the company? While such a drug is not available, you can achieve an incredible 80% reduction in your chance of developing a devastating disease by making a few simple changes to your diet and lifestyle. Disease Proof, a new book by preventive medicine specialist Dr. David Katz, provides a road map for making the diet and lifestyle changes that will “add years to life, and life to years.”
David Katz, MD, MPH, FACPM, FACP, is a remarkable physician. He received his BA from Dartmouth College and his MD from the Albert Einstein College of Medicine. According to his website, Dr. Katz “helped develop and found one of the nation’s first combined residency training programs in Internal Medicine & Preventive Medicine, and formerly served as the program’s director. Dr. Katz currently co-directs a one-year post-doctoral residency program in Integrative Medicine at his center in Derby, CT.”
The basic premise of Disease Proof is that you can slash your risk of disease by making just four adjustments to your diet and lifestyle—don’t smoke, eat healthy foods, exercise, and maintain a healthy weight. The book begins by analyzing the past 20 years worth of medical research and concludes, “the leading causes of death and disease are largely within our control because they result from what we do or don’t do with our feet, our forks, and our fingers—namely, whether they are physically active, consume a healthy diet, or smoke—on a daily basis.”
While it is true that some diseases are inherited (such as Huntington’s disease, sickle-cell anemia or cystic fibrosis), the truth is that eight out of ten serious illnesses could have been prevented by changes in diet in lifestyle. And the fact is that most medical doctors find that prescribing drugs is a lot easier than instructing patients on how to develop a healthy lifestyle—and I really don’t blame doctors for this sad state of affairs! Thirteen years ago my physical health was horrible—I was morbidly obese and suffered from a multitude of major medical problems. My family practice doctor would load me up with prescription drugs and send me on my way. When I hit my lowest point I decided to turn my life around. I am not a physician, but I do know how to thoroughly research a subject, so I started reading dozens of books on health, exercise and nutrition. Then I went on a healthy diet and started a serious exercise program. The next time I saw my doctor he said I looked fifteen years younger than the last time I was in his office, so I explained what I had done. Before I left his office I asked him, “Why didn’t you tell me to eat healthy and exercise?” He cracked a smile and said, “You know, after telling that to thousands of patients and having them all ignore me I guess I just gave up.” He was probably right—the vast majority of people have to hit bottom before they are willing to even consider changing their diet and lifestyle.
While Disease Proof does discuss DNA, genetics and the Human Genome Project, it is not a difficult book to read (medical jargon is kept to a minimum). “One of the eye-opening revelations provided by the Human Genome Project, which was completed in 2003, is that the genes themselves don’t lead to disease. It’s the interaction of certain high-risk genes and unhealthy environmental influences (including poor diet, physical inactivity, and smoking) that combine to trigger disease.” Dr. Katz discusses how diet and exercise can literally change the behavior of our genes and how heart disease, cancer, stoke and diabetes are not really the cause of death, but rather “the results or effects of how people live.”
Over half of the book is spent on nutrition, and while it does not offer a strict Paleo diet, it is what I would call “Paleo friendly”, i.e., eat a lot of fresh fruit, vegetables, lean meats and skip the pre-packaged garbage that makes up most of the typical American diet. Dr. Katz wisely observed, “The longer the shelf life of a food product (such as neon-orange cheese puffs), the shorter the shelf life of the person who consumes it regularly.”
I realize that most of the readers of this blog are probably already following a fairly healthy lifestyle, but I am certain you have a lot of family members who could use a bit of a nudge towards healthy living—this book would make a wonderful gift for them! The hardcover edition of Disease Proof retails for $26, but is available from Amazon.com for only $17. The Kindle edition sells for $12. This book was published in September of 2013 and was printed by Hudson Street Press (304 pages).
