What is dietary fiber?

Dietary fiber is a type of non-digestive carbohydrate and is one of the primary reasons to consider including plant-based foods in a regular diet. This macronutrient plays a vital role in keeping our metabolic, gut and heart health strong. Non-starch polysaccharides, cellulose, resistant starch and fructooligosaccharides are dietary fiber examples. Currently, ICMR recommends 25-40 grams of dietary fiber daily. 

Dietary fibre: Benefits & Uses

Let's understand the importance of dietary fibre for our health.

  1. Better gut health: Constipation is a prevalent digestive issue many faces and inadequate dietary fiber intake could be one of the reasons. The role of dietary fibre in keeping our bowel movements healthy is well-established. It adds bulk to the stool and supports easy elimination of waste from the body.

  3. Healthy blood sugar levels: People with diabetes can easily consume carbohydrate foods rich in dietary fibre. Studies have shown that dietary fibre helps reduce HbA1c levels, improve insulin sensitivity and overall metabolic health.
  4. Strong immunity: The majority of immune cells reside in our gut. Dietary fibre benefits our immune health by increasing the growth of good microbes in the gut.    
  5. Reduce inflammation: Low dietary fibre intake may increase the risk of inflammation in the body. Research suggests that adequate fiber intake significantly reduces the levels of pro-inflammatory markers..

Dietary fiber: Types

There are two types of dietary fiber:

  1. Soluble dietary fiber: This type of fiber is soluble in water and forms a gel-like substance. The gut bacteria can metabolize it. Soluble fiber helps reduce cholesterol levels by binding itself to harmful cholesterol to prevent it from getting absorbed. Apple, oat, sweet potato, lentils, seeds, and barley are soluble dietary fiber foods.
  2. Insoluble dietary fiber: As the name suggests, it does not dissolve in water and plays a role in adding bulk to the stool. Insoluble fiber helps prevent constipation and promote healthy bowel health. Wheat bran, nuts, seeds, whole grains, and broccoli are the sources of dietary fibre.
