Studies have shown that eating a diet rich in whole grains
and high-fiber foods may reduce the risk of diabetes by between 35 and 42 percent. An excellent source of both is heart-healthy oatmeal
: It's packed with soluble fiber, which slows the absorption of glucose from food in the stomach — keeping blood-sugar levels under control. Top oatmeal with 1 to 2 tablespoons of chopped pecans, almonds, or walnuts to add protein and healthy fat, which stabilize blood sugars further. Plus, the nuts add great crunch and flavor to your morning meal.
