Article on Impotance of Nutrition for Healing

Macronutrients Energy

Provision of adequate Kcalories (energy) is the primary

concern in facilitating wound healing. If insufficient energy

is provided, this leads to a loss of fat stores and overall

weight loss. Muscle atrophy and decreased muscle function also

results as protein is being used as an energy source.

The opposite however is true, excess kcalories may lead to

obesity, itself a complicating factor in wound healing.

Adipose (fat) tissue is poorly perfused and can be more

susceptible to breakdown. Energy sources: cereal, potatoes,

bread, pasta, sugars, oils and spreads.

Protein deficiency impairs wound healing by inhibiting

fibroblast proliferation and collagen synthesis. When protein

status is depleted, wounds have decreased tensile strength and

retarded connective tissue formation (Wallace, 1994). An

inadequate protein intake, often in conjunction with excessive

losses of protein via heavily exudating wounds (~80-100g

protein/day), will lead to deficiency which can prolong the

inflammatory response and result in oedema secondary to

hypoalbuminaemia, thereby impairing the healing process

(Brylinsky, 1995).

Protein depletion also has wider implications for wound

healing in that it depletes the systemic protein pool,

affecting all organs of the body as a result of muscle loss eg

decreased respiratory rate, reducing oxygen saturation of the

blood, and decreased cardiac output limiting tissue perfusi...
