Try to get three or more servings of various vegetables, one cup of raw leafy greens or a half-cup of other vegetables as a serving; eat dark-green leafy and deep-yellow vegetables; dry beans and peas also are good sources of fiber. Drink plenty of fluids. Six to eight glasses a day will help reduce the risk of abdominal discomfort and intestinal blockage caused by too much fiber. Get fiber from foods, NOT PILLS. Food sources are more efficient and will supply additional nutrients. Excessive use of fiber supplements can lead to digestive problems and blockages. Also wild rice, wheat bran, nuts, oats, lentils and apples. Substitute high-fiber foods such as whole-grain bread, brown rice, fruits, and vegetables for low-fiber foods such as white bread, white rice, candy, and chips. Eat more vegetables and fruits WITH their skins on. The skins are a good source of fiber. Include 2 servings of vegetables at lunch and dinner, again with skins on when if possible. Hope this helps
