lipid theory

The lipid theory suggests that cholesterol and other fats (lipids) in the blood play a key role in the development of atherosclerosis, a condition where arteries become clogged. Elevated levels of low-density lipoprotein (LDL) cholesterol can lead to the buildup of fatty deposits on artery walls, narrowing them and increasing the risk of heart disease and strokes. Conversely, high-density lipoprotein (HDL) helps remove excess cholesterol from the bloodstream. Managing lipid levels through diet, exercise, and medication can help reduce these risks and promote cardiovascular health.
