Which nutrient is the body’s primary source of energy?a) Carbohydratesb) Fiberc) Fatsd) Vitamins

Final Answer

The body's primary source of energy is a) Carbohydrates.

Explanation

Carbohydrates are macronutrients that serve as one of the body's main energy sources. When consumed, carbohydrates are broken down into glucose, which is then used by the body’s cells for energy. This energy is crucial for various bodily functions, including physical activity, cellular respiration, and brain function. While fats and proteins can also be used for energy, carbohydrates are the most readily available source and are used preferentially by the body. Dietary fiber, although a carbohydrate, is not digestible in the same way as other carbohydrates and does not directly provide energy. Vitamins play essential roles in various biochemical processes but do not provide energy themselves. Thus, carbohydrates are recognized as the primary energy source.
