Healthy sources of fats in a balanced diet include avocados, nuts, seeds, and fatty fish like salmon or sardines. These sources provide essential fatty acids, such as omega-3 and omega-6, and contribute to heart health. Olive oil and coconut oil can also be beneficial options for cooking and salad dressings. Incorporating these healthy fats supports cellular function, hormone production, and aids in nutrient absorption. Balancing fat intake within a well-rounded diet promotes overall health without excessive calories.
