Why do I need food?
Your body is built and maintained by substances that you obtain from your food. These substances are broken down and absorbed into the body during the process of digestion. They are then rebuilt into useful body-building materials.
Which foods give me energy?
Carbohydrates are substances that the body breaks down to produce energy. Starchy foods such as bread, potatoes and sugars contain carbohydrates. The body also uses some types of fat to provide energy.
Why is protein important?
Protein is an essential body-building substance that you obtain from meat, cheese, eggs, fish and several vegetable sources. Proteins are broken down in the body into amino acids that can be easily absorbed. Later, these amino acids are reassembled into useful proteins. A large part of the protein you eat is converted into muscle tissue.
