Multiple sources, including the National Strength and Conditioning Association and the American Heart Association, explain that despite popular opinion, cholesterol is not inherently bad. According to the AHA, cholesterol can either be consumed through food or inherited genetically and is a key component of the human cell membrane. Cholesterol assists in the production of salt, vitamin D and numerous hormones. There are two types of cholesterol, one good and one bad. High-density lipoprotein is considered the good type, and can help prevent high numbers of low-density lipoproteins, the bad type, from circulating in the bloodstream. High levels of LDL cholesterol are associated with heart conditions and other illnesses.
Benefits of Lowering LDL Cholesterol
High levels of LDL cholesterol can clog arteries and ultimately lead to heart failure or strokes, the AHA reports. Therefore, the primary benefit of reducing LDL is to reduce the chance of heart disease. Individuals with heart disease may experience trouble breathing and decreased endurance when performing physical activity. This is because oxygen cannot travel efficiently to and from the heart when arteries are clogged, the National Institutes of Health explain. This can lead to a painful sensation in the chest known as angina. By lowering LDL, you can see noticeable improvements in breathing and cardiovascular endurance.
Benefits of Increasing HDL Cholesterol
The AHA reports that higher levels of HDL cholesterol have been associated with a decreased risk of heart attacks and strokes, while lower HDL levels may increase the likelihood of heart disease. HDL protects against heart disease by preventing LDL from becoming clogged in the artery walls. Further, HDL prevents strokes by preventing LDL from clogging arteries that connect to the brain.
Tips For Improving Cholesterol Levels
A certain portion of LDL is inherited genetically and cannot be changed; however, the ADA explains, much of the LDL in the human bloodstream is a result of eating fatty foods. By reducing fatty food intake, you can improve your cholesterol levels in a relatively short time. Exercise and weight loss can both increase the amount of HDL in the body, as well as the ratio of HDL to LDL, the NSCA adds. By remaining conscious of saturated fat intake, becoming more physically active and losing weight, if overweight, you can can help prevent adverse effects of cholesterol throughout your life.
Warning
Consult your doctor if you are concerned about your cholesterol levels, and before beginning any new diet or exercise regimen.
