Information On Cholesterol



Cholesterol is​ a​ word associated with bad health, but cholesterol is​ actually a​ natural substance, necessary for our body's healthy functioning, and cholesterol, like most everything else in​ our lives, is​ harmful only in​ excess.

And how is​ it, then, that the very name, cholesterol, has acquired such bad connotations? Why is​ that we are always cautioned to​ 'have our cholesterol level checked' and to​ 'know our cholesterol number'? to​ understand this more fully, it​ is​ important to​ know exactly what cholesterol is, what it​ does, and where it​ comes from.

Cholesterol is​ necessary for our bodies. Our bodies must have it​ to​ maintain good health, and without cholesterol, it​ would be impossible for our bodies to​ function. Not all of​ the functions of​ cholesterol are known, but some of​ them are:

To make cell membranes, giving them stability and durability, particularly in​ our nerve tissue, brain, and spinal cord.

To make bile, where it​ aids in​ the absorption and transportation of​ fat soluble vitamins, A, D, E and K, which we must have for our health.

To manufacture certain hormones.

The principal source of​ cholesterol is​ from our own bodies. it​ is​ made primarily by the liver, and it​ is​ sent through the bloodstream to​ where it​ is​ needed by way of​ special carriers called lipoprotiens.

Another source of​ cholesterol is​ from our diets. Certain foods, such as​ meat, eggs and whole-fat dairy products all contain cholesterol. There are other foods we eat, such as​ foods high in​ saturated fats and transfats, that cause our livers to​ make more cholesterol.

Cholesterol, like other fats, will not dissolve in​ liquid, and therefore, it​ must be carried through the bloodstream, by way of​ special carriers called lipoprotiens, to​ where the cholesterol is​ needed. if​ more cholesterol is​ circulating in​ the bloodstream than is​ needed for our bodies, it​ can work with other elements in​ the blood in​ the formation of​ plaque along artery walls.

Although cholesterol is​ a​ complex substance made up of​ many subcomponents, the main subcomponents as​ they are understood at​ this time, are LDL, or​ 'bad' cholesterol, HDL, or​ 'good' cholesterol, and triglycerides.

LDL cholesterol is​ referred to​ as​ the 'bad' cholesterol, because it​ is​ one of​ the main components in​ arterial plaque. HDL cholesterol, on the other hand, helps to​ reduce plaque by returning excess LDL to​ the liver and aiding in​ its excretion. Triglyceride levels correspond to​ LDL levels.
