What are carbohydrates considered in terms of energy for humans?

Carbohydrates are considered the best source of energy for humans because they are the body's primary fuel source. When consumed, carbohydrates are broken down into glucose, which is readily used by the body's cells to produce energy. This is especially important during high-intensity activities, where glucose serves as the main source of quick energy needed by muscles.

Additionally, carbohydrates are essential for proper brain function since the brain primarily relies on glucose for energy. They also play a crucial role in metabolic processes, as they can be stored in the body as glycogen in the liver and muscles, ready to be utilized when energy demands increase.

While fats and proteins can also provide energy, they are not as readily accessible for quick energy compared to carbohydrates. This efficiency makes carbohydrates the preferred energy source during physical exertion and day-to-day metabolic activities.
