“…Improved healing of leg ulcers and wounds has been reported following three months' zinc supplementation given as 70 mg of zinc three times a day (38). However a review on nutrition and wound healing by Albina concluded that while supplementation of hospitalised patients with zinc and vitamin C may be reasonable (40), routine use of vitamin C supplementation alone is unlikely to be beneficial (41). The UK Department of Health currently recommends a reference nutrient intake of 40 mg of vitamin C daily (42), but not routine supplementation.…”

Current European recommendations are based on studies in younger age groups, which have then been extrapolated to the elderly. The quality of evidence for the specific effects of dietary intervention in older age groups is poor.The most recent European recommendations for adults with diabetes are shown in Table 10.1 (15). They emphasise energy balance and weight control, and recognise a wide variation in carbohydrate intake as being compatible with good diabetic control. The target of nutritional management is to help optimise glycaemic control and reduce the risk of cardiovascular disease and nephropathy. However, the quality of life of the individual person must be considered when defining nutritional objectives and health care providers must achieve a balance between the demands of metabolic control, risk factor management, patient well-being and safety. Compliance with all treatment modalities is likely to be compromised by increasing physical and mental disabilities, which occur more frequently in the ageing population.If beneficial changes to the diet of an elderly person with diabetes are to be achieved, access to dietetic services is needed. The following topics should be considered: body weight, physical activity and the specific micronutrient composition of the diet including carbohydrates, protein, alcohol, sodium, vitamins and minerals.

Vitamin C or ascorbic acid is a hydrosoluble vitamin derived from glucose metabolism. It acts as a reductor agent required for synthesis of collagen fibers through hydroxylation of proline and lysine. It also protects the body against damage caused by the free radicals. Humans cannot synthesize ascorbic acid as they lack an enzyme called gulonolactone oxidase. Concentrations in plasma and leukocytes reflect the levels of the diet and body deposits respectively of this vitamin. Among foods with high vitamin C levels are tomatoes, potatoes, and citrus fruits such as limes, oranges and lemons. The current recommendation of daily intake of vitamin C is 90 mg/d for men and 75 mg/d for women. Patients with chronic diseases such as cancer or diabetes or those who smoke need higher doses in their usual diet. Ascorbic acid deficiency gives rise to the appearance of scurvy. This disease is rarely seen in developed countries. The symptoms develop with plasma levels below 0.15 mg/dL. Scurvy is characterized by the presence of weakness, joint pain or skin lesions in form of petechias, gum bleeding, ease of developing bruises or delay in wound healing. The most characteristic skin manifestations are purpuric perifollicular hyperkeratotic papules and the presence of kinky hair.
