Food energy refers to the energy that our bodies obtain from the food we consume. This energy is essential for various bodily functions, including movement, growth, and maintaining body temperature. Food energy is measured in units called calories, which indicate how much energy is released when food is digested. Different types of food provide varying amounts of energy. For example, carbohydrates and fats are primary sources of food energy, while proteins also contribute but are mainly used for building and repairing tissues. Understanding food energy helps individuals make informed dietary choices to meet their energy needs.
