Dietary myths are common misconceptions about food and nutrition that can lead to confusion and unhealthy choices. For example, many people believe that eating fat makes you gain weight, but the body needs healthy fats for energy and nutrient absorption. Understanding the role of different nutrients is essential for a balanced diet. Another prevalent myth is that all carbohydrates are bad for you. In reality, whole grains, fruits, and vegetables provide essential vitamins and minerals. It's important to distinguish between refined carbs, which can be unhealthy, and complex carbs, which are beneficial for overall health and energy levels.
