97 peer-reviewed publications from 1980 to the present were examined. Of
these, the authors found enough similarities to compare 236 “matched pairs”.
Matched pairs take into account co-measurability issues. As an example, tomatoes
grown organically on one farm and grown conventionally on another close by, with
climate, aspect, soil types, plant genetics, irrigation, nitrogen levels and
harvest practices all relatively similar.
For 61% of these 236 matched pairs, organic food was shown to have
higher nutritional levels. For 8 out of 11 of the nutrients studied organic food
had on average 25% higher nutritional levels.

Härligt att få lite siffror på det här ämnet! Det behövs för att kunna övertyga.
Bra om man glädjer någon. Sedan är det bara att nöta in dem.
