Technically a carbohydrate, fibre is the part of plant-derived food that is resistant to human digestion and absorption. Fibre is needed to maintain a healthy digestive system supporting regular bowel movements, decreasing the time of intestinal transit, lowering cholesterol and glycemic levels, trapping substances that can be dangerous to the human organism (mutagenic and carcinogenic agents), and stimulating the proliferation of the intestinal microbiota.
