If you read articles and watch videos on the internet related to fiber you are most likely to come across two types of fiber. Soluble and Insoluble. However there are many sub categories of fiber and they have different health benefits. In this article you can read the various health benefits of such sub categories. This information is extremely beneficial and it will encourage you to take food items in a manner so that you get all the different fiber categories.
Types of Fiber and Their Health Benefits
There are several types of fiber that function differently and provide distinctive health benefits.
You may be familiar with the terms “soluble fiber” and “insoluble fiber,” but within each category there are many different fibers. Soluble fibers bind with fatty acids and slow digestion so blood sugars are released more slowly into the body. These fibers help lower LDL (bad) cholesterol and help regulate blood sugar levels for people with diabetes. Insoluble fibers help hydrate and move waste through the intestines and control the pH levels in the intestines. These fibers help prevent constipation and keep you regular.
Most Americans get both types of fiber from two sources: Their diet and added “functional” fiber. Dietary fibers are found naturally in the fruits, vegetables, nuts, and grains that we eat. Functional fiber, a growing trend in the food industry, is fiber that has been isolated and extracted from plants or animal sources and added to drinks and food products to boost their fiber content. Both sources offer the same health benefits.
Most nutritionists encourage getting fiber from whole foods that we eat because they contain many other healthful plant compounds. But if you don’t get enough fiber in your diet — 25 to 38 grams a day is ideal — added functional fibers can help fill in the gap.
Eating a wide variety of fibers is the ideal solution to gaining all the health benefits. This chart shows the most types of dietary and functional fibers, where they come from, and how they benefit health.
