 It all started with my grandma. I was just a kid when the doctor sent my grandma home in a wheelchair to die. Diagnosed with in-stage heart disease, she'd already had so many bypass operations that the surgeons essentially ran out of plumbing. Confined in a wheelchair, crushing chest pain, her doctors told her there was nothing more they could do. Her life was over at age 65, but then she heard about Nathan Pritikin, one of our early lifestyle medicine pioneers, and what happened next was documented in Pritikin's biography. It talks about Francis Greger, my grandma. It was a live-in program where everyone was placed on a plant-based diet and started on a graded exercise regimen. They wheeled her in, and she walked out. In a few weeks, she was walking 10 miles a day, went on to live another 31 years until age 96 to continue to enjoy her six grandchildren, including me. Her miraculous recovery not only inspired one of those grandkids to pursue career in medicine, but granted her enough healthy years to see him graduate from medical school. So it's really all thanks to her. During medical training, I was shocked to find out that this whole body of evidence on reversing chronic disease with lifestyle changes, opening up arteries without drugs, without surgery, was being largely ignored by mainstream medicine. Wait a second, if effectively the cure to our number one killer could get lost down some rabbit hole and ignored, what else might there be buried in the medical literature that could help my patients? I made it my life's mission to find out. That's what led me to start nutritionfacts.org, and that's what led me to write the book How Not To Die. Surfaces show people wildly overestimate the power of pills and procedures to keep them healthy. Patients believe cholesterol lowering statin drugs are about 20 times more effective than they actually are in preventing heart attacks. No wonder most people continue to rely on drugs to save them. But our leading killers aren't caused by drug deficiencies. The dirty little secret is that most people surveyed said they would not be willing to take many of these drugs if they knew how little benefit these products actually offered. Whereas cleaning up our diets is not only safer and cheaper, but can be more effective in preventing arresting and reversing some of our leading causes of death because you're treating the actual cause of the disease. Each year the CDC compiles the 15 leading causes of death and so I have a chapter on each, How Not To Die From Heart Disease, How Not To Die From Lung Disease, How Not To Die From Brain Diseases, Digestive Cancers, Infections Diabetes, High Blood Pressure Liver Diseases, Blood Cancers, Kidney Disease, Breast Cancer, Suicidal Depression, Prostate Cancer, Parkinson's disease, and How Not To Die From so-called iatrogenic causes, which is essentially death by doctor. That's the first half of the book and the good news is that we have tremendous power over our health, destiny, and longevity. The vast majority of premature death and disability is preventable with a plant-based diet and other healthy lifestyle behaviors. I didn't want to just write a reference book, though. Yes, there's thousands of citations to peer-reviewed scientific papers, but I also wanted to be a practical guide on translating this mountain of evidence into day-to-day decisions. And so that's what became the second half of the book. First I started out with a traffic light system to classify everything into red light, yellow light, and green light foods, though there are exceptions. I talk about the best available balance of evidence suggests the healthiest diet is one that minimizes the intake of meat, eggs, dairy, and processed junk and maximizes the intake of fruits, vegetables, beans, which are split peas, chickpeas, lentils, legumes in general, whole grains, nuts and seeds, mushrooms, herbs, and spices, basically real food that grows out of the ground. These are our healthiest choices. Some foods, though, have particular medicinal qualities, and so I then center my recommendations around a daily-dozen checklist of all the things that try to fit into my daily routine. So for example, I recommend a quarter teaspoon of the spice turmeric a day, a tablespoon of ground flaxseeds, berries every day, greens every day. I talk about the healthiest beverages, the healthiest sweeteners, how much exercise to get. The whole daily-dozen list with recommended serving sizes is available as free apps for both Android and iPhone. Just search for Dr. Gregor's daily dozen. There's only one diet that's ever been proven to reverse heart disease in the majority of patients, this plant-based diet. If that's all a plant-based diet could do, reverse the number one killer of men and women, shouldn't that be the default diet until proven otherwise? And the fact that can also be effective in treating, arresting, and reversing other leading killers like high blood pressure and type 2 diabetes would seem to make the case for plant-based eating simply overwhelming most deaths. The United States are preventable and related to nutrition. According to the most rigorous analysis of risk factors ever published, the global burden of disease study funded by the Bill Melinda Gates Foundation, the number one cause of death in the United States is our diet. The number one cause of disability is our diet, which has now bumped tobacco smoking to number two. Smoking now only kills about a half million Americans every year, whereas our diet kills hundreds of thousands more. So obviously nutrition is the number one thing taught in medical school, right? The number one thing your doctor talks to you about at every visit, right? How could there be such a disconnect between the science and the practice of medicine? Doctors have a severe nutrition deficiency in education. Most doctors just never taught about the impact health and nutrition can have in the course of illness, and so they graduate without this powerful tool in their medical toolbox. There are also institutional barriers such as time constraints and lack of reimbursement. In general, doctors aren't paid for counseling people on how to take better care of themselves. Of course, the drug companies also play a role in influencing medical education and practice. Ask your doctor when's the last time they were taken out to dinner by Big Broccoli. Probably been a while. It's like smoking in the 50s. We already had decades of science linking smoking with lung cancer, but it was largely ignored because smoking was normal. Most doctors smoked. The average per capita cigarette consumption was 4,000 cigarettes a year, meaning the average American smoked a half pack a day. The American Medical Association was reassuring everyone that smoking in moderation was just fine. There was the same disconnect between the science and public policy. It took more than 25 years and 7,000 studies before the first Surgeon General report against smoking came out in the 60s. You think maybe after the first 6,000 studies, it could have given people a little heads up or something? Powerful industry. And today's meat, sugar, dairy, salt, egg and processed food industries are using the same tobacco industry tactics to try to twist the science and confuse the public until the system changes. We have to take personal responsibility for our own health, for our family's health. We can't wait until society catches up to the science again because it's a matter of life and death.
