Fitting in fiber

Fiber is a substance found in plant foods. Most people eat much less than the recommended 25-35 grams of fiber per day. But getting enough dietary fiber is important because it does all of the following:

  • “Cleans out” the intestines and promotes digestive health
  • Lowers bad (LDL) cholesterol 
  • Lowers blood sugar
  • Increases feeling of fullness after a meal and slower emptying of the stomach, which both curb overeating
  • Lowers risk for diseases like heart attack, stroke, type 2 diabetes, and some cancers

Here are some recommendations for fitting enough fiber into your day:

  • Go slow. Surprising your digestive tract with more fiber than it is used to can lead to an upset stomach. Start increasing your fiber intake by a few grams per day until you work up to your goal. 
  • Start your day off right. Oatmeal and high-fiber, whole grain breakfast cereals are some of the best sources of soluble fiber. Add dried fruit or nuts for some texture and additional fiber. 
  • Consider your sources. Some of the best sources of fiber are lentils, split peas, and beans (specifically pinto, black, and navy beans)  
  • Go with the grain. Refined grains and processed foods have been stripped of fiber during processing. Skip the white rice, pasta, and flour and choose the 100% whole grain or 100% whole wheat options instead. Barley, bulgur, and bran are also rich in fiber.
    • Grain tip #1: Sneak fiber into your recipes. Add crushed bran cereal, unprocessed wheat bran, or ground flaxseed to baked products such as meatloaf, muffins, casseroles, cakes, and cookies. Use bran products as a crunchy topping for casseroles, salads, or cooked vegetables. 
    • Grain tip #2: Bake with whole grain flours. Substitute whole grain flour for half or all of the white flour when baking bread. Since it is heavier, use a bit more yeast or let the dough rise longer. When using a recipe with baking powder, increase it by 1 teaspoon for every 3 cups of whole grain flour. 
  • Veg out. Vegetables (and fruits!) are an excellent source of fiber. Leave the skin on (when appropriate, of course) to get the most nutritional bang for your buck. 
  • Make snacks count. Munch on fruits, vegetables, low-fat popcorn, and whole-grain crackers between meals for an extra dose of fiber in your day. 
  • Supplement if needed. Though the best way to get fiber is from your diet, a supplement can be helpful if you aren’t able to reach your goal. Check with your health care provider to see if this is right for you. 
  • Remember to stay hydrated. Fiber absorbs water, so when you increase your fiber intake, it is important to drink more water as well.
