Organic Produce

Higher antioxidant and lower pesticide concentrations

  • In 2014 The British Journal of Nutrition conducted a meta-analysis of 343 studies which analyzed differences between conventionally grown and organically grown foods. The data showed that antioxidant concentrations were substantially higher in organically grown crops while pesticide concentration was 4 times higher in conventionally grown crops. [Source]

Increased nutrient content compared to conventional farming

  • In 2007 the Journal of Agricultural and Food Chemistry published a study which measured the levels of two flavonoids – quercetin and kaempferol – in tomato samples grown using both conventional and organic farming systems over a 10-year period. The data showed that the organic samples had 79 percent higher levels of quercetin and 97 percent higher levels of kaempferol compared to the conventional samples. [Source]

Organic vs conventional – Nutrient Content

  • In 2001 the Journal of Alternative and Complementary Medicine published a study which found that organic crops had significantly more vitamin C, iron, magnesium and phosphorus and significantly less nitrates than conventional crops. [Source]

Organic vs conventional – Nutrient Content – no difference shown

  • In 2009 The American Journal of Clinical Nutrition published a review of 55 studies which found no evidence of a difference between nutrient quality between organically and conventionally grown foods. [Source]
