How Cholesterol Badly Affects Our Health?

Cholesterol is ldl (low-density lipoprotein) cholesterol. Ldl cholesterol is more likely to clog blood vessels because it carries the cholesterol away from the liver into the bloodstream, where it can stick to the blood vessels. Hdl (high-density lipoprotein) cholesterol, on the other hand, carries the cholesterol back to the liver where it is broken down. Here's a way to remember the difference: the ldl cholesterol is the bad kind, so call it "lousy" cholesterol - "l" for lousy. The hdl is the good cholesterol, so remember it as "healthy" cholesterol - "h" for healthy. What are some foods that have a lot of cholesterol? Meat, eggs and dairy products such as butter, cheese and milk (and stuff that's made with these things, like most cakes) have cholesterol. Fruits, vegetables, and grains (like oatmeal) don't have any cholesterol. In addition to cholesterol, it's a good idea to limit the amount of saturated fats and trans-fats, which can raise cholesterol levels in your blood.

Ldl cholesterol is also known as bad cholesterol, is one of the major risk factors for heart disease. A risk factor is a condition that increases your chance of getting a disease. In fact, the higher your blood cholesterol level, the greater your risk for developing heart disease or having a heart attack. Heart disease is the number one killer of women and men in the United States. Each year, more than a million Americans have heart attacks, and about a half million people die from heart disease. How does cholesterol cause heart disease? When there is too much cholesterol (a fat-like substance) in your blood, it builds up in the walls of your arteries. Over time, this buildup causes "hardening of the arteries" so that arteries become narrowed and blood flow to the heart is slowed down or blocked. The blood carries oxygen to the heart, and if enough blood and oxygen cannot reach your heart, you may suffer chest pain. If the blood supply to a portion of the heart is completely cut off by a blockage, the result is a heart attack. High blood cholesterol itself does not cause symptoms; so many people are unaware that their cholesterol level is too high. It is important to find out what your cholesterol numbers are because lowering cholesterol levels that are too high lessens the risk for developing heart disease and reduces the chance of a heart attack or dying of heart disease, even if you already have it.
