18 High-Fiber Foods You Should Add to Your Diet

What is a Fiber?

Fiber is a type of carbohydrate that the body cannot digest. It is found in plant foods such as fruits, vegetables, whole grains, legumes, and nuts. Fiber is an important part of a healthy diet because it has many health benefits.

Benefits of Fibre

Fiber has many health benefits, including:

• Helps to regulate digestion: Fiber helps to add bulk to stool and prevent constipation by absorbing water and making stool softer and easier to pass.
• Lowers cholesterol levels: Soluble fiber can help to lower cholesterol levels by binding to cholesterol in the intestines and preventing it from being absorbed into the bloodstream.
• Controls blood sugar levels: Soluble fiber can help to control blood sugar levels by slowing down the absorption of sugar into the bloodstream. This can be especially beneficial for people with diabetes.
• Reduces the risk of chronic diseases: Fiber has been shown to reduce the risk of developing chronic diseases such as heart disease, stroke, type 2 diabetes, and some types of cancer

Types of Fiber

There are two main types of fiber: soluble and insoluble.

Soluble fiber

Soluble fiber dissolves in water to form a gel-like substance. This gel can help to lower cholesterol levels and control blood sugar levels. Soluble fiber is found in foods such as:

• Oats
• Barley
• Peas
• Beans
• Lentils
• Fruits such as apples, citrus fruits, and berries
• Vegetables such as carrots, okra, and broccoli
