What Is The Importance Of Dietary Fibre?

‘Eat more fibre’ is something you must have heard plenty of times from your trainer or coach. But do you know why is it essential to consume a lot of Dietary Fibre? Found mainly in fruits, vegetables, legumes and whole grains, Dietary Fibres are known best for their ability to prevent or relieve constipation. But Dietary Fibre foods can also provide other health benefits such as lowering the risk of diabetes, heart diseases, some types of cancer and maintaining a healthy weight.

Let us explore Dietary Fibre at length and how it can benefit the human body in the long run-

What Is Dietary Fibre?

The unprocessed part of the food, mainly found in plants, that your human body can’t digest is called Dietary Fibre. It is a type of carbohydrate that adds mass to your diet and makes you feel satisfied faster, helping you control your weight gain. Dietary Fibre aids in digestion and helps avoid constipation. Some dietary fibre examples are fruits, vegetables, whole grains and legumes. Dietary Fibres are also known as roughage or bulk and pass out relatively intact out of the human body, unlike other food components such as fats, carbohydrates or proteins, which your body breaks down and absorbs. There are two types of Dietary Fibre - Soluble Fibre and Insoluble Fibre.

Soluble Fibre And Insoluble Fibre

Soluble Fibre is a type of Dietary Fibre that dissolves in water and forms a gel-like substance. This type of Dietary Fibre helps lower blood cholesterol and glucose. Soluble Fibre has a prebiotic effect, which means it provides nutrients to intestinal bacteria, protects intestinal mucosa, and ensures a healthy gut. These types of Dietary FIbre examples are-

  • Fruits such as apples and pears
  • Vegetables like carrots, artichokes and onions
  • Legumes such as kidney beans, lentils and black turtle beans
  • Seeds like oats, flax and sunflower

Insoluble Fibre is a type of Dietary Fibre that does not absorb water and can’t be broken by gut enzymes. This type of Dietary fibre keeps you feeling full for a longer period of time and vitalises your digestive system. Insoluble Fibres are highly effective in preventing or treating constipation. These types of Dietary FIbre examples are-

  • Whole Grains and Cereals
  • Legumes like soybean
  • Fruit and vegetable peels
  • Nuts and seeds

The amount of Soluble Fibre and Insoluble Fibre is different in every plant-based food. To reap the healthy benefits of these Dietary Fibres, you must indulge in a high-fibre diet.

A healthy gut is closely associated with a healthy immune system. Including Dietary Fibre foods in your diet can enhance your immunity system. A fibre-rich diet feeds healthy microorganisms living in our digestive tract which build a healthy gut.

Dietary Fibre For Weight Loss
High-fibre foods tend to be more filling than foods low in fibre. Frequent consumption of Dietary Fibre foods from plants can reduce the risk of obesity. These foods take a long time to digest which keeps you feeling full for a longer period of time. They also tend to have fewer calories for the same volume of food.

What Should Athletes Consider When Consuming A Fibre-Rich Diet?

A fibre-rich provides athletes with many benefits, but it can also cause digestion issues such as feeling too full due to slow digestion or bloating. Everyone’s body handles Dietary Fibre foods differently. If you indulge in a high fibre meal before a workout, it can slow you down.
