The functions of dietary fibre include: 1. Promotes Digestive Health: Fibre adds bulk to stool, helping prevent constipation and promoting regular bowel movements. 2. Reduces Risk of Heart Disease: Fibre, especially soluble fibre, helps lower blood cholesterol levels, reducing the risk of heart disease. 3. Aids in Weight Management: Fibre helps control hunger by adding bulk to meals without adding extra calories, which can help with weight management. 4. Regulates Blood Sugar Levels: Dietary fibre slows the absorption of sugar, helping to maintain steady blood glucose levels, especially beneficial for people with diabetes.
