Antioxidant impact of juice not due to vitamin C

Posted Oct 19 2009 10:06pm

One major source of antioxidants in the diet is fruit juice, particularly orange juice which is rich in vitamin C. Vitamin C is used widely in food manufacturing to prevent spoilage (oxidation). In the same way, vitamin C is believed to protect human cells from oxidation by free radicals. However, a number of clinical trials, involving vitamin C supplementation, produced disappointing results. This has left researchers wondering whether the antioxidant capacity of orange juice might be due to other nutrients, not vitamin C.
