Which nutrient is known as a primary energy source?

Carbohydrates are recognized as the primary energy source for the body. This is because they are easily broken down into glucose, which is the fuel that cells use to generate energy. When carbohydrates are consumed, the body converts them into glucose, which is then either utilized immediately for energy or stored in the liver and muscles as glycogen for later use. This quick conversion process is crucial for maintaining energy levels, especially during physical activities and exercise.

Fats and proteins can also provide energy; however, carbohydrates are more readily accessible and efficient for the body to utilize in everyday functions. Fats serve as a secondary energy source, essential for longer-duration activities, while proteins primarily play a role in building and repairing tissues rather than serving as a primary energy source. Vitamins do not provide energy; instead, they support various metabolic processes.
