Which class of nutrients serves as the body’s primary and most readily available source of energy?

Explanation

Carbohydrates are generally considered the body’s primary and most readily available source of energy, since they are broken down relatively quickly into glucose, which cells use directly for fuel. Common dietary sources of carbohydrates include grains, fruits, vegetables, and sugars. While proteins and fats can also be used for energy when needed, carbohydrates are typically the body’s preferred and most efficient energy source under normal conditions.
