A common misconception about carbohydrates in diets is that they are inherently unhealthy or lead to weight gain. In reality, carbohydrates are a vital source of energy, particularly for physically active individuals. The key lies in choosing the right types of carbohydrates; whole grains, fruits, and vegetables are nutritious options that support overall health. Refined carbs and added sugars can contribute to weight gain and health issues, but not all carbohydrates are created equal. Moderation and quality should guide carbohydrate consumption rather than blanket avoidance, allowing for a balanced diet.
