But, you are far more liable to die from dangerous cholesterol levels than dangerous airspeeds. Everyone has and needs cholesterol for such things as building cells, making hormones, and making vitamin D. Young children especially need it for development of the nervous system. Problems begin only when the level of cholesterol becomes too high. Elevations in cholesterol are directly related to the risk of having a heart attack . The LDL is then calculated from these numbers.
Triglycerides are the chemical form in which most fats exist in food as well as in the body.
High levels are associated with heart disease. The higher the HDL the better. I would like to see it over 50. A high HDL is great news. Even if you eat no cholesterol or saturated fat, your liver will still make as much cholesterol as your body needs, often way too much if you are genetically predisposed.
