In a healthy diet, it is crucial to limit saturated fats and trans fats, commonly found in processed foods, red meats, and full-fat dairy. High intake of these fats can raise cholesterol levels and increase the risk of heart disease. Instead, focus on incorporating unsaturated fats from sources such as olive oil, avocados, and nuts, which promote heart health. Maintaining a balanced approach to fat consumption can support overall wellness and reduce negative health impacts, making dietary choices vital for long-term health.
