Some Helpful Facts Regarding Cholesterol

Cholesterol is theoretically known as lipids or fats. It looks like a waxy powder that looks like candle wax shavings. It is pale yellow in color. All animals need cholesterol to survive. Lipids provide chemical energy as fuel for the cells which construct our body. And it is responsible for the protective shell or covering of cells. It is also essential for digestion as well as absorption of nutrients from food.

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

Different sorts of Lipoproteins.

Your bloodstream is the medium that delivers cholesterol and other lipids to each cell in the body. Since lipids and blood don't easily mix properly, the body knows to wrap protein around cholesterol particles making it easy to flow within the bloodstream. This is where the word lipoprotein gets its name. Your bloodstream carries lots of dissimilar sizes of lipoproteins which are grouped based on the density or fat composition. More fat equals lower density. Low fat and more protein means higher density. There are in fact 4 dissimilar fat containing particles in the blood. HDL or high density lipoproteins have the least total of fat (and triglycerides) and the most protein. The largest and least dense is somewhat called chylomicrons which contain the most fat; specially triglycerides. The other 2 are low density lipoproteins or LDL and VLDL or very low density lipoproteins. Most of the fat from our food and the non-cholesterol fat in our bloodstream is triglycerides. Triglycerides are made up of three fatty acids and glycerol, an alcohol. Triglycerides are vital for our health and provide much of the energy our tissues need, but excess of a good thing, similar to cholesterol, can be dangerous to your circulatory health.

How LDL is created

Since triglycerides are removed from VLDL and chylomicrons, they become smaller and denser. Ultimately all that leftover is the protein and cholesterol and a minute amount of triglyceride. The liver filters out the chylomicron and recycles any leftover unlike VLDL which even after it has lost its triglyceride components, carries on to circulate. VLDL continues to change and finally ends up as LDL particles. LDL carries the most of our cholesterol. Practically all cells in the body can utilize LDL for their energy needs. However there is normally more LDL in the bloodstream than is required and the liver must clear the extra from the blood. It may use it for more bile acids for digestion or as new lipoproteins. If the liver is not able to keep up with the excess LDL, it ends up being deposited in areas it does not belong.

HDL, the Savior

High density lipoproteins are identified as the "good" cholesterol and for valid reasons. HDL is even made in the liver and intestines but it is very different than LDL. There is a maximum concentration of protein and not much fat in HDL. The two primary roles of HDL are to provide chylomicrons and VLD the protein component that allocates the liver to know they should have their fat removed. HDLs also act as scavengers and collect extra cholesterol from blood vessel linings and other locations to be transported to the liver to be disposed of.

Cholesterol Awareness. Acknowledge Your Risks For Cardiovascular Disease
Cholesterol awareness has become a very popular topic over the past 10 years or so. It seems that once we reach age 40, we are all tracking our cholesterol numbers as close as we watch our waist lines. Unfortunately both seem to increase after 40.

Finding Out About The Significance Of High Cholesterol
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.

Describing A Low Cholesterol Dietary Regimen And How To Design One For Yourself
The best low cholesterol diet, and there are many good ones to choose from, is the one you can stick to. In order to have a cholesterol lowering diet, you will need to watch the amount and types of fats you eat as well.

Revealing The Likely Causes Of Too Much 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
