Health Care: It's All About the Benjamins
The world's most deadly diseases, and the most expensive to treat, are almost completely preventable just by changing diet and lifestyle. So why don't more insurers cover preventive measures?
By Dean Ornish, M.D.
April 11, 2006 - With the legitimate concerns about pandemics of AIDS and avian flu, it's easy to forget that cardiovascular disease kills more people each year worldwide than any other disease. It's the biggest pandemic of all time. Heart disease is so common that we've become accustomed to it, thinking of it as a natural cause of death. Yet there's nothing natural about it.
Diabetes and obesity are also becoming pandemic. In just the past 10 years, the incidence of diabetes has increased 70 percent among people in their 30s, in large part because of the obesity pandemic. As a result, this may be the first generation in which children have a shorter lifespan than their parents. A major complication of diabetes is heart disease, along with nerve, vision and kidney damage.
However, heart disease, type 2 diabetes (once known as adult-onset, though an increasing number of younger people are now getting it) and obesity can be prevented in almost everyone simply by making sufficient changes in diet and lifestyle. We don't have to wait for a breakthrough in technology or a new drug; we just need to put into practice what we already know. If we did, these pandemics could be as rare as malaria is in the United States.
Last year, the landmark INTERHEART study, led by Canadian researchers, followed 30,000 men and women in 52 countries on all continents. It found that nine factors related to nutrition and lifestyle accounted for almost 95 percent of the risk for a heart attack in men and women in almost every geographic region and in every racial and ethnic group worldwide. These factors were: smoking, cholesterol, hypertension, diabetes, obesity, diet, physical activity, alcohol consumption and psychosocial issues such as emotional stress and depression.
In other words, the disease that kills the most people each year worldwide and is the single largest expenditure of health-care dollars is almost completely preventable just by changing diet and lifestyle.
