When your cholesterol is too high, the first thing to do is to change your diet and fitness style
Cholesterol is a lipid. It is a waxy fatty substance that is naturally produced by your liver. It is essential for the formation of cell membranes, certain hormones and vitamin D. Cholesterol is insoluble in water, so it cannot pass through your blood by itself. To help transport cholesterol, your liver produces lipoproteins.
