What Makes Fruits & Vegetables Healthy?

Fibre

Fibre is a term used to describe a group of carbohydrates that cannot be digested (1). There are different ways of classifying fibre; one way is according to solubility (1). Nuts, seeds, legumes, oats, apples, pears and berries are good sources of soluble fibre, which may reduce the risk of cardiovascular disease (1)(2). Vegetables and whole grains are good sources of insoluble fibre, which is important in bowel health and may reduce the risk of diverticular disease. Despite what was once thought, high fibre intake does not appear to be associated with reducing the risk of colon cancer (1)(2).  However, there is strong evidence to suggest that diets rich in cereal fibre may reduce the risk of cardiovascular disease, and diabetes (1)(2). Consuming adequate amounts of both types of fibre is key to maintaining a healthy body.

Pectin is one of the soluble fibres found in fruits and berries (1). As a soluble fibre, pectin's slow stomach emptying, delays the absorption of some nutrients in the intestine and lower blood cholesterol levels (1). Studies have shown that supplementation with pectin can lower cholesterol level (1).
