"Importance of Nutrition on Illness Recovery" is an important example of a paper on food and nutrition.   Proper nutrition is important for the normal functioning of the human body.   Recovering patients in hospitals are  especially at risk due to the weakening of the body, often  due to the illnesses they are recovering from or the medication they are receiving. As such, they require  diets that provide the body with  the  much-needed  strength in order to acquire prompt recovery. This paper explores the importance of nutrition  for recovering patients.     The human body requires energy to  work and move around each day.   This energy comes from the sun, through the plants that provide food  in the form of nutrients  (Sizer & Whitney  2013).   Carbohydrates  are broken into glucose  for the provision of energy  to the body.   Fats  fuel the body,   make up the cell membrane, aid the body in the absorption of vitamins, and act as insulation for the body.   Proteins  help with the repair, maintenance, and growth of body tissues.   Minerals,   such as phosphorous and calcium,   constitute  parts of body structures  like the  bones.   Vitamins and minerals are used by the body as regulators for digestion of food,   disposal of wastes, movement of muscles, healing wounds, obtaining energy from fats, carbohydrates, and proteins, growth of new tissues, and any other processes.   Nutrients  help maintain  the normal function and health of cells,   the  building  blocks of body tissues like muscles and bones, systems such as respiratory and circulatory and organs like liver, heart, and kidney.   Water is also important for the hydration of cells and the whole body, digestion, and removal of wastes.     Different factors influence a person’ s nutrition requirements.

For instance, the energy requirement decreases with age as  younger  people have a  higher metabolic rate than older people (Baillie  2014).   Women have lower energy needs as men have greater muscle mass, resulting in a higher metabolic rate too.   The height and build of an individual and the physical activity they engage in also determine the energy requirement and utilization.

Similarly, pregnant and lactating mothers require high nutrient foods to  cater to the growing fetus as well as  feed the growing infant with  essential nutrients.     Lack of  any or  a number of  nutrients  results in disorders that ultimately affect the normal functioning of the  cell and may lead to disorders that may affect organs, tissues, and systems of the body. For instance, a lack of vitamin E causes impaired speech and vision and loss of muscle reflexes and coordination (Sizer & Whitney 2013).   Protein deficiency may  result in growth failure while a  lack of vitamin C may bring about gum disease.   Other conditions  and diseases  may arise, such as  swollen limbs,   anemia, abnormal heart function, loss of weight and appetite, while  the body’ s immunity is also put at risk.     Nutritional Needs of Parents  Nutritional support has been used in many hospitals to provide  the nutritional substrates required for  the facilitation of all the biological processes of healing and inflammation  (Joshi 2008).   Nutrition Support Service, NST, a scientific and professional  organization is  charged with the role of  providing quality metabolic and nutrition support  within health care.   It reviews the literature, makes  necessary changes in protocols, procedures, and policies  and  educates  other health care team members on any advances in nutrition support.         Recently, scientists have realized that  malnutrition has got very serious negative outcomes on patient recovery  as  it affects  immunity,   all organ systems, and  mental and muscle function.

This will ultimately result in increased mortality, morbidity, period, and cost of convalescence (Joshi  2008).   There  have been advances  in medical  sciences  but  malnutrition remains a problem  for hospitalized patients.   A correlation exists between poor patient outcome and malnutrition.           Various  patients have differing nutrition  and diet needs. In post-operational patients,   the aim is to achieve normal body weight,   through fat deposition, muscle formation, and the achievement  of a positive nitrogen balance (Stanfield & Hui 2010).   The nutritional support should also aim to replace lost tissue,   such as blood, bone, muscle, and skin that may have been lost during surgery.   Plasma protein, which provides  important components used in the synthesis of antibodies, albumin, and enzymes among others,   may be lost through loss of fluids or blood.   It also speeds the healing process of wounds.   Inadequate nutrition  delays tissue rebuilding  process  prevents wounds from  quick  healing  and may even cause muscle weakness and  edema.         Those undergoing treatment because of burns are also in dire need of good nutrition to repair lost tissue.   University of Rochester Medical  Centre  (2014)  advises that  they need to  replace lost energy, proteins, and lean body mass.   Proteins are usually lost through the burn wounds, and since the body requires energy, muscles are broken down for the extra energy.   The diet  should  have a high content of proteins to aid in muscle rebuild.     Carbohydrates on the other hand are broken down into glucose, which is used  for energy for the burn wounds, while fats provide extra calories and essential fatty acids.

The diet however should not have too many fats as they tend to weaken the immune system.     For the elderly, the  nutrition requirements are much more serious.   Victorian State of Government  Information  (2010)  observes that they may be experiencing side effects due to their illnesses or the type of medication they are receiving like loss of appetite, swallowing disorders, cognitive impairment, anxiety, and even depression.   Good nutrition will impact positively on maintaining their skin healthy,   reverse weight loss,   heal wounds, and  fight infections.

Their diets should have higher  contents of energy,   nutrients, and proteins.     For those with diabetes, the NST must be particularly careful with their nutrition due to the imbalance between the demand and supply of insulin.   Their nutrition should aim to attain optimal metabolic results through keeping blood  pressure,   glucose levels,   and serum lipid profiles  as  normal as possible  while treating and preventing  chronic complications that may arise (Munden 2013).   Some carbohydrates have been observed to produce higher levels of glucose than others, thus patients need close individual monitoring to  determine the best nutritional diets for them.     For children,   they may be at a higher risk of infections due to poor immunity as a result of the illness and medication.   Just as underfeeding, overfeeding could also have negative consequences on the child, as too much fat may also interfere with the recovery process  (Koletzko et al.   2008).   They require a wholesome diet, comprising of carbohydrates for energy, proteins for rebuilding body tissues, and vitamins to speed the healing process and prevent re-infection.   Of concern  are  children who are having bouts of  diarrhea  as they need to replace the fluids by having adequate amounts of water  and other fluids  to prevent dehydration.     Good nutrition is essential  for the human body, with or without illness.   Bad nutrition  affects an individual’ s  general  development  and functionality of the body.

During illness, different people require different nutrition  diets  to aid in recovery, replace and rebuild lost tissue and regain lean body mass as well as prevent re-infection.
