For Better Gut Health, Try the Best Fiber Powders

Lots of people are in need of fiber in their diet. In fact, a measly 5 percent of the population in the U.S. gets enough fiber. If you get sufficient fiber, you don’t need to deal with common bowel issues like constipation. That is why eating lots of whole grains, fruits and green leafy vegetables are required. However, for those who want to bridge that nutritional gap, you can supplement your diet with quality fiber powders. Here are some of our excellent picks.

Buyers Guide

  1. What food sources are rich in fiber?

    Answer: Fiber can be acquired through foods like lentils, artichokes, split peas, lima beans and black beans. Soluble fiber takes in water in food and turns into a semi-solid substance which slows down digestion. Soluble fiber also helps minimize cholesterol levels, regulate blood sugar and lowers chances of acquiring type 2 diabetes. You can find soluble fiber in foods like oatmeal, barley, beans, flax seeds, dried peas, apples, oranges and carrots. Insoluble fiber gives the stool its bulk and it does not take in water—it allows food to budge throughout the digestive system in a faster manner to ease constipation. It also helps reduce risks for cardiovascular diseases and diverticulitis. Insoluble fiber is found in foods like nuts, seeds, wheat bran, brown rice, bulgur and green leafy vegetables.

  2. What are the fiber sources used in dietary supplements?

    Answer: There are 4 sources of fiber used in dietary supplements. Psyllium is gathered from seed husks and contains a mix of both soluble and insoluble fiber. Methylcellulose is gathered from plant cellulose and is the soluble fiber kind. Inulin is derived from chicory root and is the soluble fiber kind. Wheat dextrin is sourced from wheat and is a soluble fiber type.

  3. How much fiber should one take daily?

    Answer: The Academy of Nutrition and Dietetics suggests that men should consume at least 38 grams of fiber each day while women should consume at least 25 grams. Fiber supplements can be taken on an empty stomach.
