Causes of high cholesterol
Undesirably high levels of blood cholesterol are a growing problem across the developed world and it seems likely that its' rising incidence is diet-related. More prepared, refined foods are typical, allied to a general over-consumption of food and insufficient physical activity due to more sedentary lifestyles. High consumption of saturated animal and vegetable fats are primary causes.

The bulk of cholesterol in the body is synthesised by the liver, where, combined with fats and protiens it forms very-low density lipoproteins (VLDL) whose purpose is to carry digested fats to various structures, for use in a variety of ways. In the process they change to low density lipoproteins (LDL) which are the type which is liable to deposition in the artery walls causing atherosclerosis. Fortunately the liver also produces high density lipoproteins (HDL) which collect the harmful LDL and return it to the liver for disposal.
When, however, excess fats are eaten the liver is stimulated to produce more lipoprotiens than the system can handle and the system becomes unbalanced leaving excess LDL in the bloodstream where it does its' damage. Fortunately a variety of treatments are available and your doctor or dietician will doubtless advise which would be the most appropriate choice for you.
