2. Different functions

Calorie is the energy consumed by the human body every moment. This energy is provided by the thermogenic nutrients in food. Nutrients in food that produce calories include protein, fat, and carbohydrates.

They are oxidized to produce heat for the body to maintain life, growth, development and movement. Food energy refers to the energy released from food used throughout the entire digestion process in the body to maintain various life activities in the body and perform external work.

3. Different units

The basic unit of heat is usually the unit of thermal energy, that is, the unit is calories. 1 calorie refers to the heat absorbed by 1 gram of water rising by 1°C. Since the average person consumes 2,000,000 calories per day, this value is too large. In nutrition, kilocalories are often used as the unit of food calories, 1kcal + 1000cal.

Energy is produced from carbohydrates, fats and proteins through oxidation in the body. The units for measuring energy are joules, kilojoules and megajoules.
