Leading Research
One of the organizations leading the research is The Organic Centre, which is dedicated to advancing and communicating evidence-based research on organic agriculture. They’ve looked at some of the differences between organic and conventional that have been discovered so far. From the hundreds of studies, they identified 236 scientifically valid “matched pairs” of organic and conventional foods, and found the organic foods were nutritionally superior in 67% of the cases, vs. 37% for conventional.
