Carbohydrates are considered the body's primary energy source from food because they are readily broken down into glucose, which is a crucial fuel for our cells. When consumed, carbohydrates undergo digestion and metabolic processes that convert them into glucose, which then enters the bloodstream and is transported to cells where it can be used immediately for energy or stored for later use. This makes carbohydrates vital for high-energy activities and overall body function, particularly for the brain, which relies heavily on glucose as an energy source.

Fats, while also a significant source of energy, are utilized primarily when the body is at rest or during prolonged, lower-intensity activities. Vitamins and minerals, on the other hand, do not directly provide energy but are essential for various bodily functions and processes that support overall health. Therefore, carbohydrates are uniquely positioned as the primary source of energy in the diet.
