Common misconceptions about nutrition include the belief that all fats are bad, carbohydrates should be avoided, and high-protein diets are only for bodybuilders. In reality, healthy fats, such as those from avocados and nuts, are crucial for bodily functions. Carbohydrates are essential for energy, especially for active individuals; the focus should be on consuming whole grains rather than refined sugars. Moreover, protein needs vary per individual, and consuming protein is beneficial for everyone, not only athletes. Educating oneself on these topics helps foster a balanced and healthy approach to dieting.
