understanding Nutrition

The word nutrition comes from the Arabic of Ghidza which means food. Food is anything that is worn or used by humans to be alive. (Yuniastuti, Ari. 2008)

Nutritional status (manutrition status) is a picture of a state of balance between the needs of substance intake - nutrient for the growth process. The imbalance between the intake to the needs of substances - nutrients will lead to disruption of metabolic processes in the body which in turn affects the growth process of physical and non physical. Real picture of the imbalance caused by the need for intake of nutrients will be visible on the physical growth that is taking into account height, weight, and body size. (BOHKASIM. 2009)

Nutritional science is the study of processes occurring in living organisms, including retrieval and processing of solid and liquid substances from food (digestion, transport and excretion) are needed to maintain life, growth, proper functioning of body organs and produce energy.
