Food is an important source of nutrients or the chemical necessary for the growth and repair of the different body tissues. The type and amount of nutrients essential for the process of growth vary as per the age, gender, and other physiological specifications. The recommended optimal intake of essential nutrients varies as per different established criteria.

Growth model is an important mean of identifying the essential nutrients of an organism, since malnutrition can be considered as an essential indication of a lack of certain important nutrients. Despite the presence of this justification, it is still difficult to identify the level of optimal growth. As an example, during earlier days the bottle fed infants had a lower growth in comparison to the ones who were breast fed. But these days, the advanced and better developed infant formulas have increased the growth of infants, in comparison to the infants who were breast fed. It is therefore important these days for the intake of optimal levels of all the required nutrients for a healthy well being. The different criteria used for identifying normal physiological processes these days are cognitive performance, tissue composition, detailed nutritional status, etc.
