Were you looking for information about Cholesterol? Cholestreol is a common misspelling of cholesterol.
Cholesterol, a substance found in your body's cells, helps the body hold cells together and make hormones, vitamin D, and substances that digest foods. While some cholesterol is necessary to help the body function properly, high cholesterol levels can cause serious medical problems. Cholesterol is not only made by your body, but it can also come from the food you eat (such as meat, cheese, and eggs). The only way to determine your cholesterol level is to have a blood cholesterol test.
