NASHVILLE, Tenn. -

Several Tennessee groups are playing a role in the fight against diabetes.

The Tennessean reports some state YMCAs are joining the National Diabetes Prevention Program, in which counselors help at-risk people with diet and exercise.

Memphis has already started a program, Chattanooga is launching one, and a program is expected to be in Middle Tennessee soon.

The Governor's Foundation for Health and Wellness is considering a similar program using telephone and web counselors that could reach more people, especially in rural areas.

Vanderbilt University scientists are also studying how particular foods affect diabetics. They're looking for diabetics 31 to 60 years old who don't smoke and don't take insulin. Participants will get nutrition counseling and help with glucose management and problem solving.
