Saturated fats can adversely affect the heart, as excessive consumption is linked to an increased risk of heart disease. High levels of saturated fats can raise LDL cholesterol levels in the bloodstream, contributing to arterial buildup and increasing the risk of cardiovascular events. The American Heart Association recommends limiting saturated fat intake to maintain heart health. Instead, replacing saturated fats with unsaturated fats, such as those found in olive oil, nuts, and fatty fish, can promote better heart health and reduce disease risk.
