Cholesterol is a key factor in heart attacks and strokes. Your body makes this fat-like substance for use in cell walls and some hormones. You also get some in foods, especially from animal sources. Cholesterol travels through the bloodstream on carriers called lipoproteins: low-density lipoprotein (LDL), and high-density lipoprotein (HDL).
Plaque-narrowed artery with reduced blood flow 
High levels of LDL, called “bad cholesterol," can lead to plaque buildup that hardens and blocks arteries (atherosclerosis). According to the American Heart Association, atherosclerosis increases risk for heart attack and stroke. HDL, "good cholesterol', takes cholesterol to the liver to be removed from your body, which may protect against heart disease . The CDC cites that nearly 32% of American adults have high LDL, and only 1 in 3 have it controlled .
There are no symptoms to high cholesterol. The National Cholesterol Education Program recommends getting your cholesterol checked once every 5 years . You can minimize your risk of high cholesterol by:
1. Eating a low-fat, high-fiber diet
2. Maintaining a healthy weight
3. Getting 2.5 hours of exercise/week
4. Not smoking
