Fibres

Dietary fibres are the part of food not broken down in the small intestine, where most food is digested and absorbed. Fibres are in foods from plants. Dietary fibres provide bulk to maintain good bowel health and regularity, help lower blood cholesterol levels, and help regulate blood sugar levels.The average Canadian eats less than 20 grams of fibre each day. The recommended amount is about 30 to 40 grams a day. Too much fibre, though, is not healthy. Eating large amounts of fibre may stop your body from absorbing the iron and minerals it needs and can also cause bowel obstruction. Increase the amount of fibre you eat gradually.

There are 2 kinds of dietary fibres - soluble and insoluble.

Insoluble fibres come from the walls of plant cells and are found in whole grains, dried peas, beans and lentils. Wheat bran is the richest source of insoluble fibres. Insoluble fibres speed the movement of food through the digestive tract. These fibres hold water, increase fecal bulk and contribute to regularity. This protects against constipation and intestinal disorders.

Soluble fibres form gels which absorb water. When eaten as part of a low fat diet, soluble fibres are particularly effective in controlling blood cholesterol and sugar levels. Fruits, vegetables, oat bran, oatmeal, and dried peas, beans and lentils are particularly good sources of soluble fibres.
