Dr Anitra Carr, Researcher at University of Otago, New Zealand, presentation at 1st International Symposium on Kiwifruit and Health: http://www.kiwifruitsymposium.org/presentations/health-and-immune-function-benefits-of-kiwifruit-derived-vitamin-c/
Vitamin C is an essential micronutrient. Unlike most animals, we have lost the ability to synthesise our own vitamin C and must therefore obtain it from our diet. Fresh fruit and vegetables are the best source of vitamin C, and regular and adequate daily intake of vitamin C is required to prevent marginal vitamin C status (hypovitaminosis C) and the potentially fatal deficiency disease scurvy. Kiwifruit are an outstanding source of vitamin C with one kiwifruit providing twice the Recommended Dietary Intake (RDI) of vitamin C.
