What do carbohydrates primarily provide for the human body?

1. Proteins for cellular function

2. Vitamins for immunity

3. Energy in the form of glucose

4. Minerals for bone health

The correct answer is: Energy in the form of glucose

Carbohydrates primarily serve as a vital source of energy for the human body. When consumed, carbohydrates are broken down into glucose, which is the primary fuel used by cells for various bodily functions. This energy is essential for physical activities, brain function, and overall metabolism. Unlike proteins and vitamins, which play distinct roles in bodily functions, carbohydrates are predominantly recognized for their capability to deliver energy efficiently. This makes them a crucial component of a balanced diet, especially for individuals engaged in regular physical activity or intense exercise, as the body relies on glucose to perform optimally.
