What is the caloric value of carbohydrates per gram?

The caloric value of carbohydrates is 4 calories per gram. This value is widely accepted in nutritional science and reflects the energy that carbohydrates provide to the body. Carbohydrates are one of the three macronutrients essential for human health, alongside proteins and fats.

When consumed, carbohydrates are broken down into glucose, which serves as a primary energy source for the body, especially for the brain and during high-intensity exercise. Understanding the caloric value of carbohydrates is important for meal planning and nutritional education, as it allows individuals to calculate their overall energy intake based on their dietary choices.

The other options do not accurately represent the caloric content of carbohydrates. For example, while fats provide 9 calories per gram and proteins offer about 4 calories per gram as well, the values of 2 calories and 6 calories are not relevant for any of the macronutrients. Thus, recognizing that carbohydrates provide 4 calories per gram is essential for proper dietary management and energy balance.
