What is Dietary Fibre? Dietary Fibre Benefits and Its Importance

Dietary fibre is very important for your gut health. To keep chronic conditions at bay, include a healthy portion of fibre-rich foods in your diet.

We all have had days where we have digestive troubles. The common recommendation by health care professionals is to include dietary fibre in your daily diet.  In fact, dietary fibre is so critical for your overall health, that Singapore’s Health Promotion Board recommends a daily dietary fibre intake of 20 grams for women and 26 grams for men. This is because dietary fibre is very critical for gut health. So, there are lasting and long-term benefits of consuming fibre.

Dietary fibres are part of plant food. We probably don’t think much about it, but it is very important. Studies indicate that whole plant food is extremely beneficial for us and may lower body mass index, blood pressure and cholesterol levels. One of the reasons may be the goodness of a good dose of fibre.

What is Dietary Fibre?

Fibre is the indigestible part of plant food that cannot be broken down by your body. Many other food components such as carbohydrates, proteins, and fats get dissolved and absorbed, unlike fibre. It isn’t digested and it passes out for your body through the stomach, intestine and colon. It is found in foods such as whole grains, legumes, beans, vegetables, fruits and the likes.

Consuming fibre is essential for healthy gut health as it reduces constipation, heart diseases, diabetes and bowel syndromes. Gut health contributes to promoting the overall health of our body which is why eating fibre has many benefits.
