The science behind nutrition and wellness is all about learning the kind of foods which human body needs at different life stages so as to meet the dietetic requirements for suitable growth and also to maintain good health and disease prevention. Normally, from birth a toddler requires very high nutrient and energy intake for each body weight unit so as to facilitate fast growth. This is because the growth rate is highest in the first-year period and goes down slowly when the child is two years old, with equivalent decrease in energy and nutrient requirements (Thibodeaux 1).
During this stage, nutrition needs drastically increases until this duration of fast development is over. Adulthood starts at 14 to 15 for girls, while for boys is from 18 to 19 years. At this age, one requires to take a lot of calories for fuelling his/her busy lifestyle. In addition, this is the period to take a lot of calcium to help the bones grow strong and also folic acid and iron.
It is commonly at this particular age where young adults begin to gain body fat and reduce their physical activities and this results to fat accumulation around the abdominal. This is why bad nutritional practices like eating food with a lot of fat, low carbohydrate and excessive amount of meat, causes obesity even in young people. In this case, lack of consistent physical activities and the indulgence in reckless foods become the major causes.
Reducing one’s intake of energy is very significant at the adulthood onset as well as making sure that every nutritional requirement is met. To accomplish this, one should ensure that he/she consumes adequate energy amount depending on someone’s body weight, physical fitness as well as muscle versus body fat. Therefore, foods which are selected for providing the energy should be very nutritious and contain high amounts of vital nutrients like vitamins, proteins and minerals (Thibodeaux 1).
A middle-aged person requires to balance his/her intake of energy depending on the level of physical activities to avoid accumulation of body fat. Therefore, the need of caloric slightly decreases during this stage. Another thing is that, people within this stage requires to take more fatty acids which is said to contain unsaturated fat and thus helps to lessen inflammation as well as improving cholesterol. It is also vital to ensure that one meets iron needs to help keep from sluggish feelings and to boost the function of immune system.
Nutritional practices as well as the choices of food are associated with wellness and has an impact to fitness, health, management of weight and chronic diseases prevention like cancer, diabetes and cardiovascular diseases. For grown-ups aging from 18 to 50 years, management of weight is usually a primary factor to attain good health and wellness. In this case, for people in middle age to maintain good health, they have to be learn about their body energy requirements. At this level, people needs to balance their intake of energy in accordance to level of physical activity.
This stage begins at 50 whereby the number of calories required in someone’s body each day decreases. This is because metabolism decelerates during this stage and so foods with low calories are the ones recommended. On the other hand, energy requirements start to decline mainly due to the decrease of activity levels. These variations in decrease of energy requirements and body composition can be avoided by maintaining consistent physical activities, which facilitates maintaining lean muscle mass as well as preventing deposition of surplus body fat. Most of the elderly people should take medications in order to control various diseases such as, diabetes, cardiovascular disease and hypertension (Thibodeaux 1).
