Wellness
Half a cup of sliced radishes has about 9 calories, plus 8.6 mg of vitamin C (10% DV). (USDA) The NIH Office of Dietary Supplements says the body needs vitamin C to make collagen, which helps wounds heal, and that vitamin C improves absorption of iron from plant foods and helps the immune system work properly.
