Ask the doctor: Finding fiber in wheat-free diets

Q. Is the avoidance of wheat a good thing? I feel better since I've been on a wheat-free diet, but I've noticed it's harder to get the amount of fiber I need.

A. You're right that we all benefit from fiber in our diets. We need about 20-35 grams a day, but most of us get less than half of that. Getting adequate fiber reduces a person's risk of heart disease, diabetes, high blood cholesterol, and many gastrointestinal disorders. Wheat, rye and barley are all good sources of fiber, but they also contain a protein called gluten.
