How can energy content of food be worked out?
A calorie is the amount of energy required to raise a volume of water a certain amount. This historically was determined by completely burning food surrounded by water. The Atwater system averages the components of food to determine a calorie count, because our bodies do not derive energy from certain types of food. In this system protein and carbohydrates add 4 kilocalories per gram to a food's total, whereas fat adds 9 kilocalories per gram.

The amount of heat that a food gives off is measured in?
Energy from food is measured in calories or kilocalories (or Calories with a capital "C"). On food labels, the Calorie (kilocalorie) form is used.A calorie is the amount of energy it takes to heat up one gram of water one degree Celsius. It is about 4.2 Joules.A Calorie (or kilocalorie) is the amount of energy it takes to heat up one kilogram of water one degree Celsius. It is about 4.2 KiloJoules.
