( In one of the most comprehensive and de...)Organic is healthier: Kiwis prove that green is good

In one of the most comprehensive and definitive studies of its kind to date, a team of researchers at the University of California, Davis have proven that organically grown kiwifruit contain more health-promoting factors than those grown under conventional conditions. The research is reported in the SCI’s magazine Chemistry & Industry. The debate over the relative health benefits of organic versus conventional food has raged for years, with UK environment secretary David Miliband declaring in January that buying organic is just a lifestyle choice.

The Davis scientists, led by Drs. Maria Amodio and Adel Kader, showed that organically grown kiwifruit had significantly increased levels of polyphenols, the healthy compounds found in red wine and coloured berries. They also had a higher overall antioxidant activity, as well as higher levels of ascorbic acid (vitamin C) and important minerals compared with their conventionally grown counterparts (Journal of the Science of Food and Agriculture DOI 10.1002/jsfa.2820). Their work differed to previously inconclusive studies, as they were able to compare like-for-like with kiwis grown next to each other on the same farm at the same time, in the same environmental conditions. Kader added: “[previous] studies did not include phenolic compounds in the comparison.?

The two categories of kiwifruit showed other differences which Kadel believes are most likely due to the fruits having to be able to survive against pests in the absence of pesticides. For example, organic kiwis had thicker skins, which could help the fruits resist insects, and higher antioxidant activity which is thought to be a natural by-product of stress.

However, some people are still unsure about the potential benefits of antioxidants and other compounds elevated in organic farm produce. Carl Winter, director of the FoodSafe Program at UC Davies, asks whether these increases in nutrients and antioxidants are of any appreciable healt
