Diabetes is a disease that affects your body's ability to properly use and store sugars from the foods you eat. Your body either does not make or does not respond to insulin, which is the chemical that causes glucose to be removed from your blood after a meal. While most diabetics can enjoy all foods in moderation, your diet should consist mainly of healthy foods full of vitamins and minerals. Fish is an excellent food for diabetics because it provides many of the nutrients found in meat without unnecessary saturated fat and calories. The American Heart Association indicates that you should have two 3.5-ounce servings of fish per week for the greatest health benefits.
