Immobility is a major risk factor for pressure sore development, especially when malnutrition is present. Lack of sufficient nutrients can be the reason that a wound does not heal completely. Nutrients particularly necessary for the health of skin include protein, vitamin C, vitamin A and Zinc.
Protein is primarily found in meat, foul, fish, eggs, milk and milk products, nuts and in dried peas and beans.
Vitamin C is found in citrus fruits, tomatoes, peppers, greens, raw cabbage, strawberries, pineapple and potatoes.
Vitamin A is found in dark green and dark yellow vegetables and fruits, egg yolks, liver and dairy products.
Zinc is primarily found in meat, fish, turkey, whole grain products, sunflower seeds and dried beans.
Adequate fluid intake is also necessary for keeping the skin healthy. In healing, the work of vitamins and minerals depend upon the presence of water in the body. In preventing pressure sores, water strengthens the skin, making it less susceptible to breakdown.
