Iic. Read and translate text c. What is food?

Food is essential to the nutrition of any human being or any form of life. If there is no food there is no life; if the amount or kind of food is inadequate, growth is stopped and the capacity to work is lost.

The term «food» is commonly refered to those substances that we eat. Milk, eggs, tomatoes, and flour are accepted as foods. Scientifically speaking foods are not so much substances that we eat, as substances that supply us with certain nutrients when they are eaten. Foods supply us with energy, build and repair tissues, and regulate body processes. Foods which we eat are often complex substances, which meet more than one of these body needs. One food may supply with both energy and building material, another may regulate body processes and give energy. The contribution that a food makes to the body depends on its constituents and the ability of the body to utilize them. The chief constituents of foods are classified into six groups: carbohydrates, proteins, fats, minerals, vitamins, and water.

The body's need for energy is met through carbohydrates, fats and proteins. Its need for building and repairing tissues is mainly met by proteins and minerals. The regulation of body processes is commonly regarded as particular function of water, proteins, vitamins, minerals, organic acids and cellulose. Though water, proteins, carbohydrates, and fats make up the largest quantity of the food constituents, the others constituents are also important.
