Most people know it is healthier to eat foods low in cholesterol, but they don't really know why it is so important. They also don't know exactly what cholesterol is and how it affects the body.
What is Cholesterol?
Cholesterol is an important fat-like substance found in the body's blood and cells that, among other things, helps produce cell membranes and hormones.
Where Does It Come From?
Cholesterol is naturally found in the human body and in certain types of foods people eat. Most cholesterol is made within the body, while what a person consumes accounts for 25 percent of his body's makeup of cholesterol.
What Are Lipoproteins?
Cholesterol is carried through the body by lipoproteins. There is good (HDL, high-density lipoprotein) and bad (LDL, low-density lipoprotein) cholesterol. While the body creates LDL cholesterol, levels can be increased because of genetics and too high an intake of foods laden with cholesterol, saturated fat and trans fat.
Cholesterol Factors
Too much LDL cholesterol causes a fatty build-up in the bloodstream that increases the risk of heart problems or stroke. On the other hand, high amounts of HDL cholesterol appear to lower the risk. A body high in triglycerides (fat in the body) often has high cholesterol levels. Studies show a high level of Lp(a) cholesterol, a mutation of bad cholesterol, causes a more rapid development of blocked arteries.
What is a Cholesterol Count?
A doctor determines if someone has a healthy cholesterol level by drawing blood and measuring the cholesterol count. The body's LDL cholesterol, HDL cholesterol, triglycerides and Lp(a) cholesterol are included in this count. When there is a dangerous amount of cholesterol in the blood, it is called hypercholesterolemia.
Maintain a Healthy Level of Cholesterol
To make sure your is in check, it is a good idea to get a cholesterol screening, maintain a diet low in saturated fat and cholesterol, and avoid being overweight through regular exercise.
