It is a common misconception that carbohydrates cause the body to produce or store fat. However, this only occurs when they are consumed in excess, which can also happen with fats and proteins. If you consume too many calories from any source — be it carbohydrates, fats, proteins, or alcohol — and your calorie intake surpasses your output, you are likely to gain weight.
When consumed in appropriate amounts, carbohydrates form an essential part of a healthy, balanced diet. Bread provides a staple food for a significant portion of the global population, serving as the primary source of energy required for bodily functions. Additionally, it facilitates the intake of essential vitamins and minerals.
