Colesterol LDL, often referred to as "bad cholesterol," is a type of lipoprotein that carries cholesterol through the bloodstream. High levels of LDL can lead to the buildup of plaque in the arteries, increasing the risk of heart disease and stroke. It is important to monitor LDL levels as part of overall cardiovascular health. To maintain healthy LDL levels, individuals can adopt a balanced diet low in saturated fats and trans fats, engage in regular physical activity, and avoid smoking. Regular check-ups with a healthcare provider can help assess cholesterol levels and provide guidance on maintaining heart health.
