Monitoring cholesterol levels is important for overall health because it helps assess cardiovascular risk. High levels of LDL cholesterol (often termed "bad" cholesterol) can lead to the buildup of fatty deposits in arteries, heightening the risk of heart disease and stroke. Regular testing enables individuals to make informed dietary and lifestyle adjustments to manage cholesterol levels effectively. A diet low in saturated fats and enriched with omega-3 fatty acids can promote heart health and mitigate risks associated with abnormal cholesterol levels.
