What Is the Optimal Diet for Human Beings?
The United States has the world's highest rates of obesity and chronic illness. People are spending more and more of their lives sick.
Health-care spending, which should more accurately be called disease-care spending, now consumes nearly 18 percent of the U.S. GDP, and it keeps rising. Three-quarters of this money is going to treatment of chronic diseases, most of which are preventable and linked to the food we eat.
The good news is that modern research gives us tremendous knowledge about the link between diet and disease, and about the real sources of health. Science knows, unequivocally, what it takes to dramatically increase the likelihood of living a thriving and vibrant life.
While most doctors receive less than 24 hours of nutritional education in 4 years of medical school, some have bucked the status quo and devoted decades of their lives to cultivating the wisdom their peers are so lacking.
We sought out the wisdom of some of the most seasoned experts—people whose programs are rooted in science, and whose results are unassailable. If you want the honest truth about your diet and your health, read on . . .

Dean Ornish, M.D.
Simple and Proven Breakthroughs That Are Changing the World
Dean Ornish, M.D., is one of the greatest medical pioneers in the world. His research has demonstrated—for the first time—that integrative changes in diet and lifestyle can reverse heart disease, turn on health-promoting genes, slow aging, and slow or even reverse early stage prostate cancer. Medicare and many of the largest insurance companies have made his program the first lifestyle-based approach they have ever covered. Chosen by Forbes as “one of the seven most powerful teachers in the world,” Dr. Ornish's work is changing the face of medicine.
Dr. Ornish challenges the myth that you have to choose between what's good for you and what's fun for you. His research proves that better diet can lead to better sex, more energy, and a happier life.
JOHN ROBBINS: Your results have been extraordinary. Patients in your program see their angina reverse or decrease as early as the first few weeks. Blood flow to the heart improves, often in a month or less. After a year, even severely blocked coronary arteries become measurably less blocked. It seems that as the years go by there is even more reversal and more improvement. Have you seen comparative improvements in patients following the more moderate American Heart Association Guidelines or any other program that you know of?
DR. DEAN ORNISH: Moderate changes may be enough to prevent heart disease in some people, but they are usually not enough to reverse it. We were able to show in a scientific way that most traditional recommendations didn't go far enough. The more you change your diet and lifestyle, the more you improve in virtually every way we can measure, whether it is your heart disease improving, your PSA coming down, or your gene expression changing. We found that over 500 genes were changed in just three months, with the up-regulating or turning on of genes that prevent disease, and down-regulating or turning off of genes that help promote disease. Particularly what are called the RAS oncogenes that promote cancers of the prostate, breast, and colon were down-regulated. These processes are much more dynamic than anyone had realized. The more we look, the more we find.
Some people think taking a pill is easy and everyone will do it, but that changing diet and lifestyle is difficult, if not impossible, and hardly anyone will do it. What we're finding is actually the opposite. Adherence to most medications, whether they are cholesterol-lowering drugs or blood pressure pills, is only about 30 percent at three or four months. But we are getting 85–90 percent adherence after a year in Nebraska, Pennsylvania, and West Virginia, even though West Virginia leads the United States in heart disease. The reason is that the pill may not make you feel better, but changing your diet and lifestyle will. The better you feel, the more you want to keep doing it so you get into a virtuous cycle. That is one of the reasons people are continuing to do it—not just to live longer, but to live better.
JOHN ROBBINS: So they enter the program because they have some medical problem that they want to alleviate and they end up changing their life in a way that creates benefits across the board. It seems as though you have found an entry point into people's lives that is healing in a profound sense.
DR. DEAN ORNISH: Well it is, and that is why I love doing this work. You know, we are all going to die of something. The mortality rate is still 100 percent, it is one per person. But the question is not just how long we live, but also how well we live.
There is a belief that you have to choose between what is good for you and what is fun for you. But we're saying you can have both. You can have more fun, have better sex, sleep deeper, enjoy your food more, and not have all those aches and pains.
The ancient swamis, rabbis, priests, monks, and nuns didn't develop techniques like meditation, yoga, and so on to unclog their arteries or lower their blood pressure. But it turns out that they developed some really powerful tools for transformation that are also physiologically healing. I can't tell you how many patients have said things to me like, “Even if I knew I wouldn't live another day longer, I would still make these changes now that I know what they are like because my life is transformed.”
What is most meaningful to me is how we can work with people to use the experience of suffering in whatever way they are feeling it as a catalyst and a doorway for transforming their lives. For some, it is physical suffering, because they have angina or chest pain. For others, it is the suffering of depression or isolation. If we can work at that level, then we find that people are much more likely to make lifestyle choices that are life enhancing rather than ones that are self-destructive.
To me it is really about transformation, and then on a physical level, just about everything we measure tends to get better. We're seeing dramatic improvements in things that were never measured before. We found that even telomerase increased by 30 percent in the first three months.
JOHN ROBBINS: Why it that important?
DR. DEAN ORNISH: Dr. Elizabeth Blackburn won the Nobel Prize in 2009 for her co-discovery of telomerase. Telomerase repairs and lengthens our telomeres, which are the ends of our chromosomes. Telomeres control aging, which in turn controls how long we live. So as your telomeres get shorter, your life gets shorter.
She had done a pioneering study with women who were caregivers of parents with Alzheimer's or kids with autism. The more stress the women reported feeling and the longer they reported feeling that way, the lower their telomerase and the shorter their telomeres were. It made headlines because it was the first study showing that even at the genetic level, chronic stress can actually shorten your life.
What was one of the more interesting findings of this study is that stress is not simply what happens to you, it is how you deal with it. You could have two women who were in very comparable life situations, but one was coping much better than the other. It wasn't the objective measure of stress that determined its effects on telomerase; it was the women's perception of it. So when people learn how to meditate and do yoga and use other methods to manage stress, they can be in the same job or the same family or the same environment and react in different ways.
