    There are many vital roles of Cholesterol
    Cholesterol is produced by almost every cell in the body.

    Cholesterol in cell membranes makes cells waterproof so there can be a different chemistry on the inside and the outside of the cell.

    Cholesterol is nature’s repair substance, used to repair wounds, including tears and irritations in the arteries.

    Many important hormones are made of cholesterol, including hormones that regulate mineral metabolism and blood sugar, hormones that help us deal with stress, and all the sex hormones (testosterone, estrogen, progesterone, etc.).

    Cholesterol is vital to the function of the brain and nervous system.

    Cholesterol protects us against depression; it plays a role in the utilization of seratonin, the body’s feel-good chemical.

    The bile salts, needed for the digestion of fats, are made from cholesterol.

    Cholesterol is a powerful antioxidant that protects us against free radicals, and therefore against cancer.

    Cholesterol, especially LDL-cholesterol (the so-called bad cholesterol), helps fight infection.

    Cholesterol does not cause heart disease. The only bad cholesterol is oxidized cholesterol found in food heated at high temperatures like powdered milk, powdered eggs, powdered cheese, hard meats, etc. The cholesterol your body makes is not bad. The cholesterol found naturally in whole foods like eggs, cream, butter, whole milk, liver is not bad. It’s the processed foods you have to stay away from!

    Cholesterol is a lipid found in the cell membranes of all tissues, and it is transported in the blood plasma of all animals. Cholesterol is also considered a sterol (a combination steroid and alcohol). Because cholesterol is synthesized by all eukaryotes, trace amounts of cholesterol are also found in membranes of plants and fungi.

    The name originates from the Greek chole- (bile) and stereos (solid), and the chemical suffix -ol for an alcohol, as researchers first identified cholesterol in solid form in gallstones by François Poulletier de la Salle in 1769. However, it is only in 1815 that chemist Eugène Chevreul named the compound "cholesterine".[2]

    Most of the cholesterol in the body is synthesized by the body and some has dietary origin. Cholesterol is more abundant in tissues which either synthesize more or have more abundant densely-packed membranes, for example, the liver, spinal cord and brain. It plays a central role in many biochemical processes, such as the composition of cell membranes and the synthesis of steroid hormones. Cholesterol is insoluble in blood, but is transported in the circulatory system bound to one of the varieties of lipoprotein, spherical particles which have an exterior composed mainly of water-soluble proteins. The main types, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) carry cholesterol from and to the liver, respectively.

    According to the lipid hypothesis, abnormally high cholesterol levels (hypercholesterolemia) and abnormal proportions of LDL and HDL are associated with cardiovascular disease by promoting atheroma development in arteries (atherosclerosis). This disease process leads to myocardial infarction (heart attack), stroke and peripheral vascular disease. As high LDL contributes to this process, it is termed "bad cholesterol", while high levels of HDL ("good cholesterol") offer a degree of protection. The balance can be redressed with exercise, a healthy diet, and sometimes medication.

  • Hi there

    Cholesterol is a type of lipo-protein (fat and protein) that is found in your blood, body and brain.

    There are lots of type of cholesterol in the body, the main ones are: Low Density (LDL) Very Low Density (VLDL) and High Density (HDL).

    Eating foods high in cholesterol has very little effect on the cholesterol level in your blood. Eating foods high in saturated fat (found in animal/diary mainly) does raise cholesterol in your body. The way it does that is quite complicated.

    Eating saturated fat is much more effective at raising your cholesterol than eating cholesterol.

    Foods with a high cholesterol content are egg yolks and offal (kidney, liver, brains etc) … yuk eh!!

    Good look.
