Dietary fats vary in their health effects based on their chemical structure. Unsaturated fats, such as those found in olive oil and avocados, are generally considered beneficial, promoting heart health. In contrast, saturated fats from processed foods and red meats can raise cholesterol levels. Trans fats are particularly harmful, linked to increased heart disease risk. Balancing fat intake by prioritizing healthy fats while limiting saturated and trans fats is crucial for maintaining optimal health, supporting weight management, and reducing the risk of chronic diseases.
