Frequently asked questions
Why cooked foods often have less calories than uncooked?
Does food lose calories in cooking process?
Often food absorbs water during the cooking process and its mass increases. As a result the amount of nutrients per unit of weight goes down. For example, 100 g of uncooked brown rice contains 367 calories. After cooking rice absorbs 200 g of water and its mass increases to 300 total. It still contains 367 calories in total, however the amount of calories per 100 g now is reduced to 122 calories (367 / 3 = 122).
