A common misconception about fat in diets is that all fats are harmful and should be avoided. In reality, fats are an essential macronutrient necessary for various bodily functions, including hormone production and nutrient absorption. Healthy fats, such as monounsaturated and polyunsaturated fats found in avocados, nuts, and fish, can support heart health and aid in maintaining a balanced diet. It's crucial to differentiate between healthy fats and trans or saturated fats, which can pose health risks when consumed in excess.
