Ask the Doctor: How Different Foods Affect Blood Sugar Levels

Question: How do different foods affect my blood sugar levels?

Dr. Rajiv Roy, with the Sharp Rees-Stealy Chula Vista Endocrinology Department, responds:

Simple carbohydrates, such as white bread and table sugar, are absorbed quickly into the blood stream and raise blood sugar levels. Whole grain carbohydrates, such as whole wheat pasta and whole wheat bread are absorbed more gradually and raise the blood sugar levels to a lesser degree. As a rule, lean proteins, high fiber foods and fats do not raise blood sugar levels like carbohydrates do. Thus, most meals and snacks should contain a combination of carbohydrates, lean proteins and a small amount of fat for optimal blood sugar levels.
