Fibre is vital for a balanced diet. It supports digestive health, heart health, and overall well-being. Many people in the UK do not get enough fibre daily. Adding high-fibre foods can provide great fibre benefits, like a healthy gut and lower disease risk.
A gut-friendly diet should include both soluble and insoluble fibre, as they have different roles. This article covers how fibre aids healthy digestion tips, its long-term health effects, and top dietary fibre sources to add to your meals.
Understanding Fibre: What It Is and How It Works
Fibre is a carbohydrate that the body cannot digest. Unlike other carbs that break down into sugar, fibre moves through the digestive system mostly intact. It has two main types:
1. Soluble Fibre
Soluble fibre dissolves in water and forms a gel-like substance, slowing digestion. It helps:
- Lower cholesterol.
- Regulate blood sugar.
- Feed gut bacteria as a prebiotic.
Sources: Oats, apples, carrots, flaxseeds, lentils, and beans.
2. Insoluble Fibre
Insoluble fibre adds bulk to stool and speeds up food movement through the stomach and intestines, preventing constipation.
- Promotes regular bowel movements.
- Lowers the risk of digestive issues.
- Aids weight management by increasing fullness.
Sources: Whole grains, nuts, seeds, brown rice, and vegetables like broccoli and cabbage.
