  • You must have heard it before that dietitians insist on eating more fibre. But are you fully aware of why fibre is good for your health? Dietary fibre is found mainly in vegetables, fruits, legumes, and whole grains. It has the capacity to prevent or soothe constipation. But fibre-rich foods can provide other essential health benefits as well, such as lowering the risk of diabetes, some types of cancers, heart diseases, etc. Choosing tasty foods that do provide fibre is not hard. You have to find out how much dietary fibre you require, the types of foods that contain it, and how you can add them to snacks and meals.

  • The Academy of Nutrition and Dietetics proposes that for every 1,000 calories you absorb daily, you eat nearly 14 grams of fibre. This means that roughly 24 grams of fibre are needed for women, and 38 grams of fibre is needed for men. Researchers have found that dietary fibre intake through millet or a wheat-based diet is usually higher than a rice-based diet.

What is dietary fibre?

Dietary fibre is a part of the plant-based diet that cannot be digested or absorbed by your body; it is also perceived as bulk or roughage. Unlike other food elements, such as carbohydrates, fats, or proteins, your body cannot easily break down and absorb the fibre. Instead, it passes somewhat unchanged through your abdomen, small intestine, colon, and out of your body.

Classification of fibre

Fibre is generally classified as soluble (dissolves in water) or insoluble (does not dissolve in water).

1. Soluble fibre

This type of fibre dissolves in the water and forms a gel-like substance. It helps in lowering glucose levels and blood cholesterol. Soluble fibre can be found in beans, oats, apples, pears, citrus fruits, barley, carrots, and psyllium (isabgol).

2. Insoluble fibre

  • This type of fibre stimulates the material movement through your digestive system and increases stool bulk. Hence it can be beneficial to those who strive with irregular stools or constipation. Insoluble fibre can be found in whole-wheat flour, nuts, wheat bran, beans, etc. It is also present in various vegetables like potatoes, cauliflower, and green beans.

  • The quantity of insoluble and soluble fibre varies in different plant-based foods. To obtain considerable health benefits, you should eat a broad combination of high-fibre foods.

6 Benefits of dietary fibre

1. Reducing cholesterol

The presence of fibre in the digestive system helps reduce the cholesterol absorption of your body. This is particularly true if you use statins (medications to lower cholesterol) and take fibre supplements such as psyllium (isabgol) fibre.

2. Promoting a healthy weight

High fibre diets like vegetables and fruits tend to contain low calories. Also, the presence of fibre can slow the digestion process in the stomach to let you feel fuller for a longer time.

3. Aids in achieving a healthy weight

High-fibre foods are more filling than low-fibre foods, so it becomes possible to eat less and remain satisfied for a more extended period. High-fibre foods take longer to consume and are less energy-dense, which means they contain fewer calories for a similar amount of food.

4. Adding bulk to the digestive tract

People who suffer from constipation or a passive digestive tract should add fibre to their daily diet. Fibre can naturally add bulk to the digestive tract. As your body does not digest it, this increases intestinal movement.

5. Promoting blood sugar control

Our body takes longer to break down foods that are high in fibre. This enables you to conserve more invariant blood sugar levels, which is especially beneficial for those who have diabetes.

6. Reducing gastrointestinal cancer risk 

  • Eating the required amount of fibre can protect you against specific types of cancers, including colon cancer. There are multiple reasons for this. One such reason is that many fibres (like pectin in apples) contain antioxidant-like properties which prevent cancer. 

  • Fibre gives numerous health benefits, but it is essential to gradually incorporate foods rich in fibre over a few days to avert adverse effects, such as gas and bloating.
