Cholesterol
Cholesterol is an organic chemical substance and is a steroid of fat. High levels of this steroid fat can cause real problems with humans leading to heart and circularity problems as the fat builds up layers in vital veins thereby restricting blood flow to vital organs such as the heart and can n some cases cause heart failure. On the other hand humans require this essential and important steroid fat to keep us healthy, as it responsible for creating and maintaining membranes within our bodies, the trick is to get the intake balance correct. Cholesterol was first discovered in 1769 in the gallstones.

How accurate are those home cholesterol testers?
Home cholesterol tester kits have nearly a 95% accuracy rate which is very close to the results of laboratory tests performed in hospitals and doctors offices.
What lipoprotein contains the highest percentage of cholesterol and is known as the bad cholesterol?
LDL is about half cholesterol. (HDL is protein rich.)
well im not 100% sure, but i know that water is polar, and only other polar things can dissolve into it. fats, i.e. cholesterol, are not soluble in water, and therefore must be nonpolar. ALSO, cholesterol is made up of four hydrocarbon rings. hydrocarbon rings, obviously, are made of hydrogen and carbon. (side note - polar compounds are formed when the difference of electromagnetivity - how much the element attracts electrons - between the elements causes an imbalance in the direction of attraction). the difference in electromagnetivity between those two elements is too little to be considered a polar molecule.
Cholesterol is a lipid that is essential for the human body to function properly. It is a core ingredient in cell membrane structure in every mammal. Cholesterol also plays an important role in producing vitamin D, bile and hormones.
As with most health issues, cholesterol levels are something that most adults don't really think about on a regular basis. That is, until they learn that they have high levels and require medication to bring those levels down. What most people don't know is that there are two different types of cholesterol carrying lipo-proteins, HDL and LDL. These lipo-proteins are essential to how cholesterol is processed within the body.
LDL And HDL, What Is The Difference?LDL, or Low Density Lipo-proteins, are considered bad, as they carry the cholesterol through the heart. These can sometimes attach themselves to the inner walls of the heart or major arteries and cause a blockage resulting in congestive heart failure, heart attacks and strokes.
The good kind of cholesterol, HDL or High Density Lipo-proteins, carry the cholesterol directly to the liver, where it is then eliminated through urine and feces. This is considered much better than going through the heart where it can cause blockages.
What Are Normal Levels Of HDL And LDL?Years of extensive research by thousands of scientists shows that levels at or below 200 mg/dl for all cholesterol is considered normal for a healthy adult. Normal levels of both LDL and HDL is the only sure-fire way to ensure that your risk for heart-attack and stroke are minimal.
The normal level for LDL is at or below 130 mg/dl, and the normal level for HDL is at or above 40 mg/dl. By increasing one's HDL level, this ensures that this particular lipo-protein is doing more transporting of cholesterol, which helps to lower the need for LDL to do this job. This, in turn, lowers the amount of plaque built up along the arterial walls and heart.
In the end, every adult above the age of 20 should get their cholesterol levels checked every five years to ensure their own good health and to reduce the risk of heart-attack and stroke.
Where can I find info on low cholesterol diet online?

Can you eat foods with fat and no cholesterol and lower your cholesterol?
Yes, olive oils and flax seed oils help considerably, in this regard.
What does it mean if you have high LDL-P?
LDL-P stands for 'LDL-Particles' (as opposed to LDL-C which is LDL-Cholesterol). It's measured with a blood test commonly called "the particle test", and your LDL-P tells you the number of LDL particles in your blood. Usually LDL-P is measured along with LDL-C to obtain a more complete, detailed measure of cardiovascular risk - some doctors believe that particle levels as well as total cholesterol matter. Treatment strategies differ depending on the relationship between LDL-P and LDL-C, so there's not a 'cut and dried' target number for LDL-P (as there is for LDL-C).
phytosterols have also been questioned
What types of fats help lower blood cholesterol?
Unsaturated fats typically is associated with lowering "bad" cholesterol (LDL) and raising "good" cholesterol (HDL)
What food is the best to bring down cholesterol?
Any food rich in soluble fiber like flax seed meal, pitted dried prunes and walnuts.
How does the body control cholesterol levels?
it is controlled by the brain which tells the liver to create good cholesterol in the body. however when bad cholesterol gets inside the body it clogs up the blood vessels leading to high blood pressure and the body can not remove it.
High-density lipoproteins (HDL) are composed mainly of proteins, with only small amounts of cholesterol. HDLs are often referred to as "good cholesterol" because they help remove cholesterol from artery walls and transport it to the liver for elimination from the body. Higher HDL levels actually protect against coronary heart disease.
Low-density lipoproteins (LDL) are composed mainly of cholesterol and have very little protein. They are often referred to as "bad cholesterol" because they are primarily responsible for depositing cholesterol within arteries. High levels of LDLs are associated with an increased risk for coronary heart disease.
