Nutrition is a part of science that studies, as well as analyzes and interprets, the relational effect of nutrient in food and other food substances to the growth, life and health maintenance, reproduction, and diseases of people and also of living organisms. This includes the food intake, absorption and assimilation, biosynthesis, catabolism and excretion.
The food intake or diet of a person represents the kinds of food he/she eats, and which is determined by the availability of the food, how the food was processed or prepared, and how good the food was. In order to gain a healthy diet, food must be cared for in such a way that it is stored well, prepared and cooked properly, so that the nutrients in it are preserved from oxidation, heat or leaching, and from the risk of food poisoning. Nutrients that are organically derived are made up of carbohydrates, fats, proteins and amino acids, and vitamins, as well as water, oxygen, and minerals.
When we age, our dietary needs will change and this kind of process will continue all through life, and with that, the food nutrients that we take will also undergo adjustments as we grow older. It is not just the stages of age where the diet of people changes, but there are also factors that contribute in the dietary change, such as economic, psychological, and social aspects.
