Cholesterol is a fat-like, waxy substance in the body that has adverse effects on our health in excessive amounts. Although too much cholesterol in the blood imposes serious health risks, your body needs it in certain amounts. Proteins in the blood known as lipoproteins carry cholesterol. In contrast to low-density lipoprotein, or LDL, high-density lipoprotein -- HDL or the "good" cholesterol -- may positively impact your health.
Prevents Osteoporosis
Cholesterol may aid in the prevention of osteoporosis. With exposure to sunlight, the body is able to convert cholesterol into vitamin D. Along with calcium, vitamin D builds strong bones by increasing bone mineral density. This aids in the prevention of osteoporosis and the risk of fractures from weak bones.
Decreases Risk of Atherosclerosis
LDL cholesterol increases the buildup of plaque in our arteries, leading to a condition called atherosclerosis. Atherosclerosis increases the risk of heart disease, obesity and stroke. This risk can be decreased by increasing levels of HDL cholesterol in the blood to reduce or eliminate LDL. Select foods that contain healthy unsaturated fats and reduce or avoid those that are high in saturated and trans fat.
Decreases Risk of Cardiovascular Disease
Increased levels of good cholesterol in the blood may prevent the risk of cardiovascular disease. According to a study published in a 2004 issue of the "European Heart Journal Supplements," for each 1 mg/dL increase of HDL cholesterol levels, there is a corresponding 2 to 3 percent reduction in the risk of developing coronary heart disease. One study, the Framingham Heart Study, showed that high HDL levels protect against coronary heart disease even with higher LDL levels in the blood. In general, higher HDL levels coupled with lowered LDL levels may be beneficial in preventing heart, lung and respiratory diseases. Further studies are needed to confirm the independent benefits of HDL cholesterol, however.
Contributes to Necessary Functions
The body needs cholesterol for normal functioning and daily processes. Cholesterol helps to produce hormones in the body, develop cells and tissues, and develop organs for fetus development. Inadequate levels of good cholesterol in the body may hinder proper development, function and growth in the body. Consult with your physician to determine your cholesterol levels. Ideally, healthy HDL levels are greater than or equal to 60 mg/dL of blood.
