Go organic for health benefits, research revealsDate: 06/07/2007 08:59:52

Organic fruit and vegetables could be better for our health than food grown in conventional ways, a new report suggests.
A ten-year long study compared organic tomatoes with their conventional counterparts, finding they contained double the levels of antioxidants - or flavonoids - known to have health giving properties.
Flavonoids are thought to fight heart disease, blood pressure and stroke, as well as being linked to fighting against cancer and dementia.
Dr Alyson Mitchell, food chemist at the University of California looked at the amounts of flavonoids - quercetin and kaempferol - contained in dried tomato samples.
Research, published in the Journal of Agricultural and Food Chemistry, linked the higher levels of flavonoids to nitrogen in the soil and the absence of fertilisers.
Commenting on the research to the Times, Peter Melchett, Soil Association policy director, said: "We welcome the now rapidly growing body of evidence which shows significant differences between the nutritional composition of organic and non-organic food.
"As further scientific evidence emerges from new research looking at differences between organic and non-organic food, the Soil Association will be asking the Food Standards Agency to keep their nutritional advice to consumers under review."
According to the Soil Association, sales of organic food jumped by 30 per cent in 2005.
