Food energy is defined as the energy released from carbohydrates, fats, proteins, and other organic compounds. It  is chemical energy that animals (including humans) derive from food through the process of cellular respiration. The energy value of a particular food is calculated from a knowledge of macronutrient composition and the modified Atwater factors for these macronutrients. Foods and drinks fuel the body. Energy-boosting examples include bananas, avocados, apples, and coffee. Generally speaking, all food supposedly gives you energy. But some foods are better at providing the energy kick you need to conquer the world. It gives us energy by providing energy to the cells inside our body. Carbohydrates in food are used first. Every living being has a different and individual relationship with the energy contained in food. The intimate connection between all living beings and energy is important for their survival.
