Heart and blood vessel diseases still kill more people, not only in this country, but also worldwide, than everything else combined, and yet it's completely preventable for almost everybody. It’s not only preventable: it's actually reversible. And for the last almost 29 years, we've been able to show that by simply changing diet and lifestyle, using these very high-tech, expensive, state-of-the-art measures to prove how powerful these very simple and low-tech and low-cost interventions can be like quantitative arteriography, before and after a year, and cardiac PET scans. We showed a few months ago that we published the first study showing you can actually stop or reverse the progression of prostate cancer by making changes in diet and lifestyle. Now there is an epidemic of obesity: two-thirds of adults and 15 percent of kids. What’s really concerning to me is that diabetes has increased 70 percent in the past 10 years, and this may be the first generation in which our kids live a shorter life span than we do. That's pitiful, and it’s preventable.
