Generally, nutrition is defined as a branch of science which studies and interprets the relational effect of nutrients and substances in food to the life growth, maintenance, reproduction, health and illnesses of people, including that of other living organisms. Food digestion, absorption and assimilation, biosynthesis, catabolism and excretion are processes that are taken up also in nutrition.
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 are composed 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. Contributary factors to the dietary change, aside from the aging process, are economic, psychological, and social aspects.
Options – Getting Started & Next Steps
For the first six months of a baby’s life, nutritionists strongly recommend that mothers must breastfeed their babies since breast milk is complete and full of nutrients and has antibodies which the infants need. After six months, solid food can already be given to the baby together with the mother’s breast milk.
Discovering The Truth About Wellness
The dietary nutrition for the pre-school age group considers the following food combination – carbohydrates, fruit and vegetables, milk and dairy foods, protein and good quality fats, as well as vitamins A, C, calcium, iron and zinc.
When the child reaches school age, which stretches to puberty, proportions of the nutritional requirements according to their age and physical, mental and social activities will now vary, such that it is imperative that a healthy balance of food nutrients be afforded to ensure a healthy lifestyle. At this age group level, nutritional requirement that contains proportional balanced diet of the essential foods including calcium, iron and protein with vitamin supplements must be found in the three meals taken each day – breakfast, lunch, dinner.
As we enter adulthood, the majority of our body’s growth and development will be over and the gradual slowing down requires a shift more on adult nutrition to maintain a physically active life. The dosage of food intake, at this age level, should be limited into individual portions but not forgetting to still have three meals a day and that snacking should be choosing healthier options, like whole grain toast, fruits. Since the portions are small and preparations to it can be taxing, it is best to cook large meals then freeze the rest so that the nutrients are still preserved until the next meal.
As we continue to age until we reach the elderly stage, our bodies continue to change but the appetite to eat may also change drastically to poor appetite out of biological and hormonal factors, including the limited physical mobility which can hamper in buying and preparing for the right kinds of food. It is, therefore, recommended to buy food, that are already pre-cooked and are equally nutritious, and can be frozen at a long period of time, so that small portions of it can be taken as the need arises.
