There may never be an end to arguments over whether organic food is more nutritious. But a new study is the most ambitious attempt so far to resolve the issue — and it concludes that organic fruit and vegetables offer a key benefit.
It’s a scientific reply to an analysis that some researchers at Stanford University published two years ago. That paper, which generated lots of media coverage and much controversy, reviewed more than 200 studies of organic and conventional food, and concluded that organic foods do not really offer any significant nutritional benefit.
This new analysis, from a group of scientists mostly based in Europe, crunched data from an even bigger pile of studies: 343 of them, carried out over the past several decades. It will be published Monday in the British Journal of Nutrition.
The new analysis repeats some of the Stanford group’s findings. It finds that organic and conventional vegetables offer similar levels of many nutrients, including minerals, vitamin C and vitamin E. Conventional crops are higher in protein. And there are fewer pesticide residues on organic foods, as you’d expect.
