Fiber is essential for a healthy digestive system, and it also helps with weight management, blood sugar control, and even reducing the risk of heart disease. Yet, many people don’t get enough fiber in their diet. If you’re looking to boost your fiber intake, here are 20 high-fiber foods you should be eating. This guide will give you the benefits and the best ways to include these fiber-rich foods in your daily meals.
What Is Fiber and Why Is It Important?
Dietary fiber is a type of carbohydrate that the body can’t digest. Unlike other carbs that break down into sugar molecules, fiber passes through the body undigested. It helps regulate the body’s use of sugars, keeping hunger and blood sugar in check. There are two types of fiber: soluble and insoluble. Both are important, but they have different roles:
- Soluble fiber dissolves in water, forming a gel-like substance. It helps lower blood sugar and cholesterol levels.
- Insoluble fiber doesn’t dissolve in water. It adds bulk to the stool, making it easier to pass and preventing constipation.
A healthy diet should include both types, and these 20 foods will help you meet your fiber needs.
