Controlling blood sugar.
When food is digested, carbohydrates, including both starches and sugars, break down into glucose, which enters the blood stream. The slower, the better. The best carbohydrates come from whole grains, vegetables and fruits, and legumes (which include beans, peas and lentils). Most “white” foods, like white bread, rice, white sugar, and potatoes, metabolize too quickly.
Fiber-rich foods help control blood sugar. These include fruits, vegetables, legumes, whole grains, whole-wheat products and bran.
