Healthy diet, regular exercise help stave off type 2 diabetes


Narrator:       This is Science Today. Researchers at the University of California, San Francisco, helped identify a key genetic mutation that is responsible for type 2 diabetes in up to 2.5 million patients. Dr. Ira Goldfine, who led the U.S. arm of the multi-national study, says maintaining a healthy diet and regular exercise are key for those who are genetically predisposed to the disease.

Golfine:         In more developed societies, people don't exercise as much. They drive cars, take the train. There are statistics showing that before World War II, people ate less and they didn't drive and after World War II, their caloric intake increased.

Narrator:       While the study focused on Europeans and Americans, Goldfine says that anyone living in an industrialized country is at high risk for the disease, as they adopt more sedentary lifestyles and poor dietary habits.

Goldfine:       Before World War II, there was very little diabetes in Japan and now they have a lot of diabetes and if you plot the correlation between automobile use per capita and diabetes it correlates pretty well. But in all the developing countries you're seeing this.
