While true that certified organic producers use fewer antibiotics and that organic foods can't be genetically modified, neither fact demonstrates a lower risk for chronic disease. Organic foods generally had higher vitamin C levels, but conventional foods frequently had higher lycopene and β-carotene levels. Even pesticide residues did not consistently favor organic foods, as some comparisons found higher heavy-metal concentrations in organic samples. That raised a sharper question: was the association driven by eating organic in general, or specifically by replacing conventional produce with organic? However, after reviewing four major studies, they found no consistent evidence that organic foods provide clinically meaningful health benefits over conventional foods.
