Fiber Facts: What You Should Know About Soluble & Insoluble Fiber by Jennifer Young
Fiber can be soluble or insoluble. Both are good for your health, but they have different jobs.
- Soluble fiber attracts and dissolves in water. This forms a gel and slows down digestion, which may help us feel fuller, longer.
- Insoluble fiber doesn't dissolve in water, it stays pretty much intact, helping move food and waste in our intestines and preventing constipation, like a laxative.
Staying hydrated is important, because fiber can have a reverse effect and block us up. Soluble fiber can be found in oatmeal, lentils and carrots, and insoluble fiber in broccoli, onions and grapes, just to name a few.
