What Is Cholesterol And What Does It Do?


Cholesterol is described as a waxy fat-like substance. Cholesterol is part of every living cell in the human body, an essential component of cell membranes.

Cholesterol is produced by the liver approx. 1000mg per day. It is required for functions such as the manufacture of hormones like oestrogen, cortisone and testosterone.

Apart from the human body producing cholesterol, animals also produce cholesterol.

When produce such as meat, chicken, seafood and dairy is eaten by humans, added cholesterol is obtained via the animal produce, as it is also an important component in animal cells.

The great increase in cholesterol levels for many people is not only due to an excess intake of animal produce foods. Processed foods and other foods with a high glycemic index, such as French fries, rice cakes, baked potatoes, and white bread and refined carbohydrates also increase cholesterol. Plus, soft drinks have a high glycemic index.

The conversion of such foods and drinks into energy results in carbon fragments which the body uses to make cholesterol. Saturated fats also supply carbon fragments after digestion and conversion into fatty acids and they also promote an increase in blood cholesterol.

Such foods as organ meats and crustacea are especially rich in cholesterol.

Cholesterol is vital for cell construction, but excess cholesterol is lethal and can cause obstruction.
