Different types of fats significantly affect health, with distinctions between saturated, unsaturated, and trans fats. Unsaturated fats, found in sources like avocados, nuts, and olive oil, are beneficial as they support heart health and lower bad cholesterol levels. Conversely, saturated fats, often found in red meats and full-fat dairy, can raise LDL cholesterol if consumed excessively, contributing to heart disease. Trans fats, largely present in processed foods, are particularly harmful, increasing the risk of cardiovascular issues. A balanced approach to fat consumption—prioritizing unsaturated fats while minimizing saturated and avoiding trans fats—is essential for overall health.
