If you’ve ever felt a little backed up, you’ve probably come across fiber in your search for a fix. It’s a pretty effective way to get things moving. And as it turns out, fiber can do more than help unclog those pipes. Diets high in fiber are linked with a healthy weight, lower risk for heart disease, and a healthy gut. So how can you add more fiber to your diet? Try piling your plate with one of these 10 high-fiber foods.
But first, what is fiber?
Put simply: fiber is a non-digestible carbohydrate found in plant-based foods. It differs from a nutrient that your body absorbs, but this doesn’t make it any less important. There are two kinds of fiber: soluble and insoluble. Soluble fiber is broken down in the GI tract and helps keep you feeling fuller longer. Insoluble fiber passes through the GI tract without being broken down and gives you that oomph to keep things moving in your gut.
Most foods provide both types of fiber, but soluble fibers are primarily found in fruits and vegetables while insoluble fibers are primarily found in nuts and whole-grain grain products.
As important as fiber is to your health, most Americans aren’t hitting their daily goals. Only about 5% of men and women in the U.S. are getting the recommended amounts, which is 25 grams for women and 38 grams for men.
