Cholesterol is a fatty, waxy substance that the body uses for the structure of cell membranes as well as in the production of bile. Cholesterol is transported around the body by lipoproteins, which are either high density (HDL) or low density (LDL). Maintaining a suitable balance of HDL to LDL cholesterol is important for our overall health. 

In order to help keep cholesterol levels within normal boundaries, herbalist herbalist Dr Serene Foster says: it is important to reduce saturated fat, but also to increase fruit and vegetable consumption. Soluble fibre present in porridge oats, wholegrain cereals, beans, peas and lentils is particularly important. Try to avoid having red meat more than once a fortnight and increase the amount of fish in your diet. Oily fish are particularly good because they will help to raise the good fats in your blood. In moderation nuts and seeds will also help to increase the good fats in your blood.

Exercise will reduce the bad fats in the blood, improve your circulation and help you to maintain desirable weight and reduce the body's fat. It is also important to limit salt intake."
