Tag: Ethanol energy

Ethanol, the alcohol in beverages, contains a significant amount of energy, providing about 7 calories per gram—more than carbohydrates and protein. However, the crucial question of whether humans can get energy from alcohol effectively and without negative health consequences is more complex than simple caloric content suggests.

One gram of pure ethanol, the alcohol found in beverages, contains seven kilocalories (kcal) of energy. This makes alcohol surprisingly energy-dense, packing more calories per gram than protein and carbohydrates, and only slightly less than fat.
