Saturated fat, present in red meat, butter, cheese, and tropical oils such as coconut and palm, raises serum LDL cholesterol when consumed beyond recommended thresholds. Major cardiology guidelines advise keeping saturated fat below ten percent of daily caloric intake to limit atherosclerotic cardiovascular risk. This section explains how saturated fatty acids disrupt lipid metabolism, contribute to arterial plaque buildup, and interact with other dietary components like trans fats. Readers will learn to identify hidden saturated fat on nutrition labels, select heart-healthy cooking alternatives, and plan meals aligned with clinical dietary recommendations. All content is grounded in peer-reviewed research to support practical food choices.
