New research suggests that vitamin C may reduce some of the health problems associated with diabetes. Vitamin C is an antioxidant – one of the ‘good guys’ that goes around the body mopping up damaging molecules called free radicals. Diabetics produce more free radicals which is why they are more susceptible to tissue damage leading to amputations, heart disease and blindness. The authors stress that they would not encourage people to start taking vitamin C supplements. You can obtain plenty of vitamin C from fresh fruit and vegetables such as citrus fruit, berries and green leafy vegetables.
