Welcome to Public health moment from the University of Minnesota in order to learn more about the health benefits of food. Researchers have typically focused on individual nutrients such as beta carotene, calcium, and vitamin E. But David Jacobs, a University of Minnesota epidemiologist, believes that scientists need to examine food itself. The way that foods work is that they're orchestrated combinations of constituents. Food was once alive, life is complex. For researchers, I would say that they should study food. And if they find something about a food, that's an important thing. But they should be telling us what happens to health on the basis of eating particular foods. While many people use supplements to increase their intake of certain nutrients, Jacobs recommends instead a healthy diverse diet. A tried and true safe way to get nutrients is from food. What I would suggest is diversity. We scientists don't know everything by far. My suggestion is diversity and moderation, and I would avoid those foods which I know have very limited nutrient content. With another public health moment. I'm John Finnegan.
