Whole-Grain Foods for Diabetes Prevention

Preventing diabetes could be as easy as eating whole-grain foods, including breads, cereals, pastas and pilafs.

Not only are whole-grain foods much more nutritious and fiber-rich than processed white-flour products, but a new study shows they could be beneficial in preventing diabetes, from blood sugar spikes to overeating. If you're even remotely at risk for diabetes, aim for about 6 servings of whole grains daily. Yes, tuna salad on whole wheat counts -- 2 servings.

Whole-grain foods are crammed with fiber, B vitamins, and minerals (selenium, magnesium, potassium, phosphorous, manganese, iron, and zinc). This potent combination of nutrients helps regulate blood sugar and insulin, curb appetite, control cholesterol, and lower homocysteine, a substance strongly linked with heart disease, according to a major new study of almost 1,000 men and women. No wonder nutritionists have been chanting the whole-grain mantra for years. But now diabetes experts are chanting along with them.
