Lowering Cholesterol Tips

Lowering Cholesterol TipsCholesterol is a sterol (a combination steroid and alcohol) and a lipid found in the cell membranes of all body tissues, and transported in the blood plasma of all animals.

Cholesterol is a white, waxy substance usually present in all healthy cell membranes. It is essential in production of most of the hormones. Liver produces major portion of the cholesterol in the body.

Most cholesterol is not dietary in origin; it is synthesized internally. Cholesterol is present in higher concentrations in tissues which either produce more or have more densely-packed membranes, for example, the liver, spinal cord and brain, and also in atheroma. Cholesterol plays a central role in many biochemical processes, but is best known for the association of cardiovascular disease with various lipoprotein cholesterol transport patterns and high levels of cholesterol in the blood.

Here we attempt to explain what cholesterol is, its causes, risks and how to lower it.

Function

Cholesterol is required to build and maintain cell membranes; it makes the membrane's fluidity - degree of viscosity - stable over wider temperature intervals (the hydroxyl group on cholesterol interacts with the phosphate head of the membrane, and the bulky steroid and the hydrocarbon chain is embedded in the membrane). Some research indicates that cholesterol may act as an antioxidant. Cholesterol also aids in the manufacture of bile (which helps digest fats), and is also important for the metabolism of fat soluble vitamins, including vitamins A, D, E and K. It is the major precursor for the synthesis of vitamin D, of the various steroid hormones, including cortisol and aldosterone in the adrenal glands, and of the sex hormones progesterone, estrogen, and testosterone. Further recent research shows that cholesterol has an important role for the brain synapses as well as in the immune system, including protecting against cancer.

Recently, cholesterol has also been implicated in cell signaling processes, where it has been suggested that it forms lipid rafts in the plasma membrane. It also reduces the permeability of the plasma membrane to proton and sodium ions.

Primary causes of high blood cholesterol

The problems caused by cholesterol

When excessive amounts of cholesterol are deposited in the arterial walls, they go on narrowing and hardening. After some time, the blood supply to the heart decreases. Your chances of suffering from heart disease like angina and heart attacks as well as stroke increase. 

Different types of cholesterol

Cholesterol consists of two main types: one offers protection against heart problems while the other is responsible for it. Proteins are the carriers of the cholesterol in the blood. Hence both of them together are called lipoproteins.

High density lipoproteins (HDL) move the cholesterol away from artery walls. They prevent heart disease and hence are called “good”.

Low density lipoproteins (LDL) deposit the cholesterol on the artery walls. In long run, this can cause blockage, giving rise to heart problems. Hence it is called “bad”. Ensure your LDL level is low.

Foods that contain cholesterol

Liver produces cholesterol from the saturated fats present in your diet. Hence, ensure that your diet is low in saturated fat.

The main foods rich in cholesterol are:
