The benefits of fibre are widely known and accepted. The World Health Organisation advocates for adults to consume a minimum of 25 grams of fibre daily. Unfortunately, many individuals fall short of this recommendation, leading to various issues including constipation and even more severe health concerns.

Fibre serves as a vital nutrient essential for our overall well-being. While commonly associated with maintaining regular bowel movements and a healthy digestive system, its significance extends beyond these functions.

This nutrient, categorised as a type of carbohydrate, is predominantly found in plant-based foods such as fruits, vegetables, nuts, seeds, and grains. Remarkably, fibre constitutes the indigestible portion of plants, playing a crucial role in facilitating the digestion of other foods. There are two main types of fibre: soluble and insoluble, both of which are imperative for maintaining optimal health.

Soluble Fibre

Soluble fibre, which dissolves in water, forms a viscous gel in the digestive tract. This characteristic slows down the absorption of sugar into the bloodstream, stabilising energy levels and contributing to the reduction of blood sugar and cholesterol levels. Foods rich in soluble fibre include fruits, oats, barely, nuts, and psyllium.

Notably, soluble fibre comes in two forms: pectin, found in fruits and vegetables, and gum or mucilage, present in plants’ cell walls such as beans, barley, and carrots.

Insoluble Fibre

In contrast, insoluble fibre does not dissolve in water and passes through the digestive system without undergoing digestion. It aids in processing foods, absorbing nutrients, and promoting bowel movement, thereby maintaining gut health. Wheat, corn, rice, and various vegetables are rich sources of insoluble fibre.

Benefits of Fibre for Gut Bugs

Although the human body does not digest fibre, it serves as crucial fuel for trillions of beneficial gut bacteria which metabolise it, fuelling numerous processes that support immunity, reduce inflammation, and synthesise vitamins.

Benefits of Fibre in Your Diet

The advantages of a fibre-rich diet are numerous;

• It helps to keep our digestive system healthy and helps to prevent constipation.
• It helps to regulate the body’s use of sugars, helping to keep blood sugar in check, thus reducing the risk of type 2 diabetes.
• It can support weight loss by creating a feeling of fullness and keeping hunger in check.
• It may lower cholesterol and reduce the risk of heart disease.
• It may reduce the risk of some cancers such as bowel cancer.
• It helps to soothe inflamed linings of the intestines, easing symptoms of IBS and IBD (inflammatory bowel disease).
• It can assist in the elimination of toxins and heavy metals from the gut.
• It may reduce the risk of dementia and enhance brain function.

Simple Ways to Add More Fibre into Your Diet

It doesn’t have to be difficult, here are some simple ways of achieving the benefits of fibre by adding more of these foods into your diet:

• Add a teaspoon of psyllium powder or oat bran to your breakfast cereal.
• Add a teaspoon of chia seeds, linseeds or sunflower seeds to your porridge.
• Add a pinch of flaked chia or hemp to your yogurt.
• Swap white bread with whole grain bread.
• Swap white rice with brown rice.
• Add beans or pulses to salads.
• Add lentils to a vegetable curry, soup or bolognaise.
• Make a fruit and veg smoothie in the blender.
• Add extra vegetables to your meals.
• Snack on carrot sticks and bell peppers with hummus.
• Snack on mixed nuts.

Checking food labels will help you identify the best choices. A product should contain at least 6g of fibre per 100g to be classed as high fibre.

It’s crucial to gradually increase fibre intake to prevent discomfort such as bloating and gas, particularly for individuals with digestive conditions like IBS or IBD, who may require tailored dietary guidance. Be sure to also increase your water intake to help move the extra fibre through your digestive system.
