*2.2.3 Water*

Water represents around 60 percent of the body weight. It is necessary for the use of food materials in the body and for disposal of food excess later on [2].

#### **2.3 Vitamins**

Vitamins (natural carbon-containing composites) adjust many of the body's processes [1]. They are available in small amounts; however, they are essential for physiological functions as growth and development. Vitamins can work as antioxidants, cofactors in metabolic oxidation-reduction responses, and hormones [4].
