The answer is simple, it is the consumption of food materials (nutrients) which are essential for the life processes. Nutrition plays a pivotal role in the proper functioning of human body. It has a vital role in encouraging the healing process.
Rising cases of obesity and sedentary lifestyles have led to the deterioration of human health. They increase the risk of diseases like hypertension, diabetes, wound infection, etc. Inappropriate levels of nutrition or malnourishment can slow down the healing process. This is mainly because of the direct relation between nutrition and the process of tissue repair. Wound healing is a complex process which can be impaired due to poor nutritional status. Each stage of wound healing requires certain nutrients to be present above a specified level and the absence of it can retard the process.
Wound healing process include stages like coagulation of blood, removal of bacteria and dead tissue, growth of new tissue and blood vessels, and finally wound closure with the maturation of the scar tissue. An important nutrient which plays a key role in all phases of wound healing is protein. Proteins help in tissue synthesis and repair. The dietary sources of protein include meat, cheese, poultry, etc. Protein along with other nutrients ensure a proper healing process. Anti-oxidants found in Vitamin A, C, and E and in selenium help in neutralizing the free radicals released during the healing process and transform them into harmless entities. For the healing of normal wounds, the primary factor to take care is a well-balanced nutritional diet.
The healing of chronic wounds is impaired by malnutrition. Malnutrition is reversible and early detection can promote the wound healing. The treatment commonly involves a high energy diet with the necessary supplements and nutrition delivery through tubes directly into the gastrointestinal tract or by intravenous feeding of nutrition to the body.
If a wound is developed, nutrients play a pivotal role in speeding up the healing process. The key nutrients should be available in the body in adequate levels to ensure that healing takes place in a proper manner.
