Kiwifruit better than tablets

You're better off eating a kiwifruit than chewing a vitamin C tablet, suggests new research from the University of Otago.

In a study recently published in the American Journal of Clinical Nutrition, the highest ranking journal for human nutrition research, New Zealand researchers discover that a natural fruit source of vitamin C - kiwifruit - is better absorbed than a vitamin C supplement.

Lead researcher Associate Professor Margreet Vissers says that humans require a certain level of vitamin C in all body tissues and organs to be healthy. However, like some other mammals (guinea pigs for example), we can't make vitamin C so we need to get it from our food. A lot of people use vitamin C supplements as back up.

Professor Vissers' study involved testing the uptake of vitamin C in deficient mice over a month. Mice were fed either kiwifruit or an equivalent amount of pure vitamin C. Results shows that mice fed kiwifruit absorbed vitamin C much more efficiently than those given the supplement. The vitamin C also stayed in their bodies for longer. An equivalent human study is now underway.
