What are the benefits of fiber?

Eating a high fiber diet has a lot of potential health benefits including decreased risk of heart disease, stroke, and type 2 diabetes.

A high-fiber diet can also help treat digestive problems such as constipation, diarrhea, and hemorrhoids.

However, most people don't eat the recommended amount of fiber.

What is fiber?

Fiber can be thought of as a substance found in the outer layers of grains or plants which is not digested in the intestines.

Most dietary fiber is not digested or absorbed, so it stys in your intestines where it helps regulate digestion and affects the consistency of your poop.

There are two types of fiber, Soluble Fiber and Insoluble fiber, each of which is thought to have its own benefits.

Soluble fiber dissolves in water and insoluble fiber does not dissolve in water.

Examples of foods with soluble fiber include:

• Fruits
• Oats
• Barley
• Peas
• Beans

Examples of foods that contain insoluble fiber include:

• Wheat
• Rye
• Other grains

The traditional fiber, wheat bran, is a type of insoluble fiber.

Dietary fiber is the total amount of soluble and insoluble fiber in food.
