What is the primary source of energy for the body?

The primary source of energy for the body is carbohydrates. Carbohydrates are broken down into glucose, which is utilized by the body's cells for energy. This is especially important for brain function and during physical activity, as glucose is the preferred energy source for most tissues. Carbohydrates can be quickly mobilized to provide energy when needed, making them a vital component of a balanced diet.

Fats also serve as an important energy source, especially for prolonged, lower-intensity exercise, but their breakdown is more complex and occurs at a slower rate compared to carbohydrates. While vitamins and minerals are essential for various biochemical processes and overall health, they do not provide energy in the form of calories. Therefore, carbohydrates are recognized as the primary and most efficient source of energy for the body.
