The body processes different types of fats through distinct metabolic pathways. Unsaturated fats, found in foods like avocados and olive oil, are generally considered heart-healthy and can improve cholesterol levels. Saturated fats, present in red meats and dairy, should be consumed in moderation due to their association with increased LDL cholesterol. Trans fats, often found in processed foods, are detrimental and should be avoided. The body uses fats as a source of energy and they play roles in hormone production and nutrient absorption.
