Knowing Nutrition



What is Nutrition ?

Nutrition is provision (persedian/kebutuhan) for cells and organisms, of the materials necessary (in the form of food) to support life. Diet is what organism eats.

Nutrient is including macro element and micro element. We can also define six major classes of nutrients : carbohydrates, fats, minerals, protein, vitamins, and water; where carbohydrates, fats, protein, and water are grouped as macro element, the rest is micro element. Macro element is nutrient that is needed in big propotion for our body.

Macro nutrients (such as carb, fats, protein) can be used to generate energy internally, and in either case it is measured in Joules or kilo calories (often said "Calories" only, with big “C” letter). Carbohydrate and protein provide 17 kJ (4 kcal) approximately of energy per gram, while fats provide 37 kJ (9kcal) per gram. These calculation are not strike. They also depend on many factor such as absorbtion and digestive effort that may different in every human.

What is Malnutrition ?

Malnutrition is insufficient, excessive, or imbalanced consumption of nutrients. In some places at rural area, some person maybe have less diet to eat so they get malnutrition (insufficient), while at urban area people maybe have a lot of food so they get malnutrition (excessive) also. There are places in Indonesia where almost all of people in the village have got goiter. It is caused by less iodin nutrient in their diet. Even though they have a lot of rice, vegetable, or eat meat, but the trace element (iodin) in low state, that this situation is also called malnutrition (imbalance)
