Does It Matter Where Your Fiber Comes From?

You Should Know: Whether you’re full-on fibermaxxing or just being more conscious about your daily intake, adding more fiber to your diet is generally a great idea. But “more fiber” doesn’t mean just one type from one source. Experts say our bodies get the most benefits when we regularly consume different types of fiber from a variety of plant foods.

Going Deeper: Both main types of fiber — soluble and insoluble — play different roles. Most fruits and veggies contain both. Soluble fiber is concentrated in oats, fruit, and beans, dissolves in water, and forms a gel. It regulates blood sugar, strengthens the gut lining, and lowers cholesterol. Insoluble fiber doesn’t dissolve and aids digestion. It includes whole grains, nuts, and seeds. 

Takeaway: Eating lots of different plants means eating lots of different fiber, which is crucial for gut health and digestion. It can also reduce the risk of cardiovascular disease, obesity, and other chronic illnesses.

Bottom Line: That fiber supplement you’re taking or those chia seeds you’re sprinkling on everything can tick up your fiber count, but they shouldn’t be your only source of fiber. A varied diet with plenty of plants fills many of your body’s nutritional needs
