Organic foods not only have fewer pesticides but also more antioxidant compounds
"A new report, however, says organic foods not only have fewer pesticides but also more antioxidant compounds. The findings, published in the British Journal of Nutrition, used a database of 343 previously published studies. The meta-analysis calculated that organic crops contained 18% to 69% higher concentrations of antioxidant compounds, depending on the type of antioxidant. Researchers said consumers who switch to organic fruit, vegetables, and cereals would get 20% to 40% more antioxidants.
