Some Helpful Information Regarding Cholesterol

Cholesterol is technically called as lipids or fats. It resembles a waxy powder that looks like candle wax shavings. It is light yellow in color. All animals require cholesterol to survive. Lipids supplies chemical energy as fuel for the cells that make up our body. Also it is responsible for the protective shell or membrane for cells. It is also essential for digestion and absorption of nutrients from food.

Cholesterol is essential for our sex hormones, testosterone and estrogen, and for vitamin D. Cholesterol is so vital that our body controls it so closely that if you did not eat enough dietary cholesterol, your body would make all it needs on its own. Your liver has the ability to change fats, sugars and proteins into cholesterol for its needs.

Various kinds of Lipoproteins.

Your bloodstream is the vehicle which carries cholesterol and other lipids to every cell in the body. Since lipids and blood don't easily mix well, the body knows to wrap protein around cholesterol particles making it easy to flow through the bloodstream. This is where the name lipoprotein gets its name. Your bloodstream carries many different sizes of lipoproteins that are categorized based on the density or fat composition. More fat equals lower density. Less fat and more protein indicates high density. There are actually 4 different fat containing particles in the blood. HDL or high density lipoproteins have the less amount of fat (and triglycerides) and the most protein. The largest and least dense is something called chylomicrons that contain the large amount of fat; specially triglycerides. The other 2 are LDL or low density lipoproteins and VLDL or very low density lipoproteins. Mainly the fat from our diet and the non-cholesterol fat in our bloodstream is triglycerides. Triglycerides are made up of three fatty acids and glycerol, an alcohol. Triglycerides are crucial for our health and provide a large amount of the energy our tissues require, but too much of a good thing, like cholesterol, can be hazardous to your circulatory health.

How LDL is created

As triglycerides are removed from VLDL and chylomicrons, they become smaller and denser. Ultimately all that remains is the protein and cholesterol and a minute amount of triglyceride. The liver cleans out the chylomicron and reuses any remnants unlike VLDL which even after it has lost its triglyceride components, continues to circulate. VLDL continues to alter and ultimately ends up as LDL particles. LDL carries the majority of our cholesterol. Practically all cells in the body can utilize LDL for their energy requirements. Though there is typically more LDL in the bloodstream than is needed and the liver should clear the excess from the blood. It may use it for more bile acids for digestion or as new lipoproteins. If the liver cannot keep up with the surplus LDL, it results in being deposited in places it does not belong.

HDL, the Savior

High density lipoproteins are known as the "good" cholesterol and for proper reasons. HDL is also made in the liver and intestines but it is very different than LDL. There is a high concentration of protein and not much fat in HDL. The two main roles of HDL are to supply chylomicrons and VLD the protein component that allows the liver to recognize they should have their fat extracted. HDLs also act as scavengers and collect excess cholesterol from blood vessel linings and other areas to be transported to the liver to discard it.

The Cholesterol Coronary Disease Connection
There is no clear scientifically proven explanation as to exactly how a diet high in saturated fat can be the cause of rising cholesterol in the blood.

You Should Avert From High Cholesterol Food To Remain Fit
The best way to get at that overabundance of cholesterol is, of course, to take a look at your high cholesterol food consumption and alter it to reduce the amount of that food in your diet.

Unmasking The Likely Causes Of Excessive Cholesterol
For most people, the cause of high cholesterol is poor lifestyle choices such as diet and our level of exercise, which can be modified. Both men and women can strive to attain and maintain a normal level of cholesterol, get their levels checked and take prompt action if needed.

Raising Awareness About Your Good And Bad Cholesterol Levels
The waxy substance in the human body known as cholesterol comes primarily in two basic forms, HDL and LDL. HDL, or high-density lipoprotein, is often referred to as the good cholesterol, while LDL, or low density lipoprotein, is the undesirable form of cholesterol.

The Priority Of Understanding Cholesterol Prior To Using A Cholesterol Modifying Drug
Because too much cholesterol can damage the heart and the rest of the circulatory system, we are strongly urged to keep our cholesterol at the proper levels. When you have changed what you can, if your lipid and cholesterol numbers are still in an unhealthy range, you and your doctor may decide on using a cholesterol drug.
