Why Cholesterol is a Problem

Far from being a totally unwanted substance in the body as many would probably believe, cholesterol is in fact an important constituent of certain bodily hormones such as estrogen and testosterone, and of cell membranes. In other words, cholesterol is actually something that is required and which performs vital functions within our bodies.

Why then, are we constantly told that we need to cut down our cholesterol levels? It is because our bodies actually manufacture all the cholesterol that they need. Cholesterol only becomes a problem for us when we consume it in excessive quantities. About three quarters of the cholesterol in our blood is manufactured by our bodies.

Your liver is extremely sensitive to your cholesterol requirement, so if you consume a somewhat greater quantity of it at some point, your body will manufacture a somewhat lesser quantity to keep the overall level in balance. A problem only arises when you consume so much that the ability of your body to properly balance the quantity is compromised.

The average individual requires something under about 14 grams of fat per day to enable them to acquire their requirement of essential fatty acids, but in the United States the average daily consumption is at least eight times that amount. That is, the average daily consumption is greater than 112 grams when only about 14 grams are required. This excess builds up in the arteries and sets in train a health time bomb in the bodies of the individuals concerned.

Epidemiological studies have demonstrated that cholesterol levels and blood pressure levels increase in proportion to the amount of saturated fat and cholesterol consumed. This results in an increased risk of coronary heart disease, and in fact if you eat excessive quantities of saturated fat and cholesterol and your blood pressure and cholesterol levels still do not rise all that much, you are still at a greater risk of suffering from coronary heart disease.

Cholesterol is commonly divided into two groups: good and bad. The good cholesterol is high density lipoprotein (HDL) and the bad cholesterol is low density lipoprotein (LDL). The so called good cholesterol shifts cholesterol from the artery walls and back to the liver, whereas the bad cholesterol keeps the cholesterol in the bloodstream which results in the arteries becoming clogged up with deposits. To reduce your levels of LDL limit the quantity of saturated fat that you consume and increase the quantity of fibre that you consume by eating such things as oatmeal and other whole grains as well as peas and beans and fruits. Psyllium is considered to be a very good food for reducing LDL as well. To raise your HDL levels you need to lose excessive weight and get moderate amounts of exercise, and try to have a supplement of a gram or so of Omega 3 fatty acid per day.

Animal products and processed foods are the most risky foods to consume in excess in terms of saturated fat content. It has been demonstrated that those who consume a low fat vegetarian diet maintain low levels of blood pressure, low blood cholesterol levels and low rates of heart disease.
