Plant-Based Diets as the Nutritional Equivalent of Quitting Smoking

The Best Kept Secret in Medicine.jpeg

Despite the most widely accepted and well-established chronic disease practice guidelines uniformly calling for lifestyle change as the first line of therapy, doctors often don't follow these recommendations. As seen in my video, The Best Kept Secret in Medicine, lifestyle interventions are not only safer and cheaper but often more effective in reducing heart disease and failure, hypertension, stroke, cancer, diabetes, and deaths from all causes than nearly any other medical intervention.

"Some useful lessons may come from the war on tobacco," Dr. Neal Barnard wrote in the American Medical Association's ethics journal. When he stopped smoking himself in the 1980s, the lung cancer death rate was peaking in the United States. As the prevalence of smoking dropped, so have lung cancer rates. No longer were doctors telling patients to "[g]ive your throat a vacation" by smoking a fresh cigarette. Doctors realized they were "more effective at counseling patients to quit smoking if they no longer had tobacco stains on their own fingers." "In other words, doctors went from being bystanders--or even enablers--to leading the fight against smoking." And today, says Dr. Barnard, "Plant-based diets are the nutritional equivalent of quitting smoking."

From an editorial in the journal Alternative Therapies in Health and Medicine: "If we were to gather the world's top nutrition scientists and experts (free from food industry influence), there would be very little debate about the essential properties of good nutrition. Unfortunately, most doctors are nutritionally illiterate. And worse, they don't know how to use the most powerful medicine available to them: food."

Physician advice matters. When doctors told patients to improve their diets by cutting down on meat, dairy, and fried foods, patients were more likely to make dietary changes. It may work even better if doctors practice what they preach. Researchers at Emory University randomized patients to watch one of two videos. In one video, a physician briefly mentioned her personal dietary and exercise practices and visible on her desk were both a bike helmet and an apple. In the other video, she did not discuss her personal healthy practices, and the helmet and apple were missing. In both videos, the doctor advised the patients to cut down on meat, not usually have meat for breakfast, and have no meats for lunch or dinner at least half the time. In the disclosure video, the physician related that she herself had successfully cut down on meat. Perhaps not surprisingly, patients rated that physician to be more believable and motivating. Physicians who walk the walk--literally--and have healthier eating habits not only tend to counsel more about exercise and diet, but have been found to seem more credible or motivating when they do so.

It may also make them better doctors. A randomized controlled intervention to clean up doctors' diets, called the Promoting Health by Self Experience (PHASE) trial, found that healthcare providers' personal lifestyles were correlated directly with their clinical performance. Healthcare providers' improved wellbeing and lifestyle cascaded to the patients and clinics, suggesting an additional strategy to achieve successful health promotion.

Are you ready for the best kept secret in medicine? Given the right conditions, the body can heal itself. For example, treating cardiovascular disease with appropriate dietary changes is good medicine, reducing mortality without any adverse effects. We should keep doing research, certainly, but educating physicians and patients alike about the existing knowledge regarding the power of nutrition as medicine may be the best investment we can make.

Of course, to advise patients about nutrition, physicians first have to educate themselves, as it is unlikely they received formal nutrition education during their medical training:

Dr. Greger’s 2015 Live Year-in-Review Presentation

Food as Medicine

View my new live presentation here: Food as Medicine: Preventing and Treating the Most Dreaded Diseases with Diet

Every year I scour the world's scholarly literature on clinical nutrition, pulling together what I find to be the most interesting, practical, and groundbreaking science on how to best feed ourselves and our families. I start with the thousands of papers published annually on nutrition (27,000 this year--a new record!) and, thanks to a crack team of volunteers (and now staff!), I'm able to whittle those down (to a mere 8,000 this year). They are then downloaded, categorized, read, analyzed, and churned into the few hundred short videos. This allows me to post new videos and articles every day, year-round, to NutritionFacts.org. This certainly makes the site unique. There's no other science-based source for free daily updates on the latest discoveries in nutrition. The problem is that the amount of information can be overwhelming.

Currently I have more than a thousand videos covering 1,931 nutrition topics. Where do you even begin? Many have expressed their appreciation for the breadth of material, but asked that I try to distill it into a coherent summary of how best to use diet to prevent and treat chronic disease. I took this feedback to heart and in 2012 developed Uprooting the Leading Causes of Death, which explored the role diet may play in preventing, arresting, and even reversing our top 15 killers. Not only did it rise to become one of the Top 10 Most Popular Videos of 2012, it remains my single most viewed video to date, watched over a million times (NutritionFacts.org is now up to more than 1.5 million hits a month!).

In 2013 I developed the sequel, More Than an Apple a Day, in which I explored the role diet could play in treating some of our most common conditions. I presented it around the country and it ended up #1 on our Top 10 Most Popular Videos of 2013. Then in 2014 I premiered the sequel-sequel, From Table to Able, in which I explored the role diet could play in treating some of our most disabling diseases, landing #1 on our Top 10 Most Popular Videos of 2014.

Every year I wonder how I'm going to top the year before. Knowing how popular these live presentations can be and hearing all the stories from folks about what a powerful impact they can have on people's lives, I put my all into this new 2015 one. I spent more time putting together this presentation than any other in my life. It took me an entire month, and when you see it I think you'll appreciate why.

This year, I'm honored to bring you Food as Medicine, in which I go through our most dreaded diseases--but that's not even the best part! I'm really proud of what I put together for the ending. I spend the last 20 minutes or so (starting at 56:22) going through a thought experiment that I'm hoping everyone will find compelling. I think it may be my best presentation ever. You be the judge.

You can watch it at no cost online, but it is also available on DVD through my website or on Amazon. If you want to share copies with others, I have a five for $40 special (enter coupon code 5FOR40FAM). All proceeds from the sales of all my books, DVDs, downloads, and presentations go to the 501c3 nonprofit charity that keeps NutritionFacts.org free for all, for all time. If you want to support this initiative to educate millions about eradicating dietary diseases, please consider making a donation.

After you've watched the new presentation, make sure you're subscribed to get my video updates daily, weekly, or monthly to stay on top of all the latest.
