The claimEvidence A · guideline-tier
Organic food is more nutritious and safer
The evidence
Organic and conventional food have nearly identical nutrient content (Smith-Spangler 2012, Stanford, 237 studies). Organic certifies how food is produced, not its nutrition or safety.
The mechanism, in brief
The nutritional difference between organic and conventional produce is small, and there is no strong evidence that this small difference matters for health. What decides how much you get from a plate is how much you ate and how many colors, not whether it wore that sticker.
