Which dietary component is essential for maintaining blood glucose levels in diabetic patients?

1. Fats

2. Proteins

3. Carbohydrates

4. Vitamins

The correct answer is: Carbohydrates

Carbohydrates are the primary source of glucose in the diet and play a crucial role in maintaining blood glucose levels, especially for individuals with diabetes. When carbohydrates are consumed, they are broken down into glucose, which enters the bloodstream and provides energy. It is important for diabetic patients to manage their carbohydrate intake effectively to prevent spikes or drops in blood glucose levels. While fats and proteins are also important dietary components, they do not have the same direct impact on blood glucose levels as carbohydrates. Fats provide energy and support cell function, whereas proteins are vital for tissue repair and growth but do not significantly influence blood sugar levels in the same way that carbohydrates do. Vitamins are essential for overall health but do not directly regulate blood glucose levels. Therefore, understanding the role of carbohydrates is key in diabetes management and helps patients maintain their blood glucose within the target range.
