Nutrition is the process of breaking down food and substances taken in by the mouth to use for energy in the body or it is the process of obtaining and consuming food. By practicing a healthy diet, many of the known health issues can be avoided.[1] There are six major classes of nutrients: carbohydrates, fats, minerals, protein, vitamins, and water. Carbohydrates may be classified as monosaccharides, disaccharides, or polysaccharides depending on the number of monomer (sugar) units they contain. They constitute a large part of foods such as rice, noodles, bread, and other grain-based productProteins are structural materials in much of the animal body (e.g. muscles, skin, and hair). They also form the enzymes that control chemical reactions throughout the body. Each protein molecule is composed of amino acids, which are characterized by inclusion of nitrogen and sometimes sulphur (these components are responsible for the distinctive smell of burning protein, such as the keratin in hair). The body requires amino acids to produce new proteins (protein retention) and to replace damaged proteins (maintenance). As there is no protein or amino acid storage provision, amino acids must be present in the diet
