Dietary fats should be consumed in moderation, particularly saturated fats and trans fats, as excessive intake can lead to higher cholesterol levels and increased risk of heart disease. While healthy fats such as monounsaturated and polyunsaturated fats are essential for overall health and should be included in the diet, balance is key. Emphasizing sources like nuts, seeds, and avocados can provide necessary nutrients while limiting unhealthy fats optimizes heart health and supports weight management.
