Your blood glucose may rise and then rapidly fall if you eat a high-carbohydrate meal with very little fiber. Because fiber is like a sponge, absorbing and releasing glucose, a high-fiber meal will slow down these rapid changes and prevent the "highs and lows."
High-fiber foods are low in fat and provide essential nutrients, such as vitamins C, B6, A, E, folate, and carotenoids. The National Institutes of Health recommends that adults eat 20-35 grams of fiber per day. It can be found in many different types of plant foods, including whole-grain breads and cereals, fruits and vegetables, and many types of beans. The best way to add fiber to your diet is to slowly slip in more high-fiber foods. Here are some tips to get you started:
- Add grated carrots, zucchini, or celery to your usual meals.
- Use a handful of rolled oats to top casseroles such as macaroni and cheese.
- Add garbanzo beans or kidney beans to rice dishes.
- When baking cakes or cookies, use oat flour for half the flour in the recipe and oat bran or oatmeal for the other half to provide extra flavor and crunch.
