HDL (high-density lipoprotein) is the "good" cholesterol carrier that helps remove excess cholesterol from arteries and deliver it to the liver. Lifestyle changes - exercise, quitting smoking, and healthy fats - help improve HDL; overall heart risk depends on the full lipid profile.
Animal foods contain dietary cholesterol, but saturated and trans fats have a larger impact on LDL. Lower your cholesterol by choosing plant-based foods, unsaturated fats, fish, and soluble fiber while limiting red/processed meat, full-fat dairy, and trans fats.
Lowering LDL cholesterol works best by cutting saturated/trans fats, boosting soluble fiber, and choosing plant-forward foods. Dietary cholesterol (only in animal foods) matters less than the type of fat and overall pattern.
Limit fatty red meats, many fast-food items, and high-fat dairy like whole milk and butter to reduce saturated fat and lower LDL cholesterol. Practical swaps: lean cuts, plant proteins, low-fat dairy, and unsaturated oils.
Cholesterol balance matters for heart and stroke risk. Combine diet, exercise, weight control, smoking cessation, stress management and, when needed, medications - guided by regular testing - to lower your risk.
