Dietary Fiber

Dietary fiber is often effective in improving mild constipation. However, it has less consistent results with more severe constipation, possibly worsening symptoms in patients with slow colonic transit (colonic inertia). A physician or registered dietitian can provide individual advice on dietary fiber consumption.

When adding fiber to the diet, it is best to do so slowly over a period of weeks. If gas, bloating or distention occur, try reducing the dose of fiber and reducing consumption of gas-producing foods, such as beans, cabbage, legumes (e.g., peas, peanuts, soybeans), apples, grapes, and raisins.

Experiment with fresh foods and don't be afraid to try new foods and recipes. Here are a few practical tips for adding fiber to your diet.

Vegetables

  • Cook in microwave to save time and nutrients
  • Cook only until tender-crisp to retain taste and nutrients

Beans

  • Presoaking reduces the gas-producing potential of beans if you discard the soaking water and cook using fresh water

Fruit

  • Snack on fruit anytime, anywhere
  • Leave peelings on fruit whenever possible
  • Use fresh and dried fruit in muffins, pancakes, quick breads, and on top of frozen yogurt

Grains

  • Choose whole-grain varieties of breads, muffins, bagels, and English muffins
  • Mix barely cooked vegetables with pasta for a quick pasta salad
