The Many Benefits Of A High-Fiber Diet

Fiber is a non-digestible carbohydrate that is found in beans, legumes, vegetables, fruits, and grains.

Consuming enough fiber each day is imperative for maintaining good health and function. Unfortunately, however, many individuals fail to consume enough.

This article will provide detail on sixteen excellent high-fiber foods that you should look to incorporate into your diet to boost your fiber intake.

The Health Benefits Of Fiber

Before moving on to the high-fiber foods, let’s first consider some of the health benefits associated with increased fiber intake.

1) Enhanced Digestive Health

Fiber plays an important role in regulating digestion and causing regular bowel movements. Failing to consume enough fiber may lead to constipation or diarrhea.

Furthermore, consuming ample fiber every day may also enhance gut health as the consumption of specific fibers can promote the growth of good bacteria (1)

2) Decreases Cholesterol Levels

Cholesterol is a waxy-like substance that the body requires for maintaining the structure of cells and transport, amongst other things.

Having a high level of a type of cholesterol, known as low-density lipoproteins (LDL), can increase your risk of developing heart disease. However, consuming adequate fiber has been found to reduce LDL levels (2). 

3) Better Blood Sugar Regulation

Research on high fiber consumption has indicated that it may also help to regulate blood sugar levels and prevent them from spiking (3).

Based on these findings, it has been suggested that consuming plenty of fiber may reduce the risk of developing type 2 diabetes.

4) Body Weight Management

For those who aspire to lose weight, eating a lot of fiber is recommended. This is partly due to the fact that fiber can suppress appetite and leave you feeling fuller for longer.

It is thought that fiber draws in water in the intestine which consequently slows the absorption rate of nutrients thus increasing feelings of fullness (4). 

5) Reduced Disease Risk

A combination of the above health benefits combine to reduce the risk of death from cardiovascular, infectious, and respiratory-related diseases. (5).
