Organic food contains more vitamins, minerals, enzymes and micro-nutrients than conventionally raised food. There is a growing body of evidence documenting how farming methods can influence the nutritional content of foods. A 2019 study on dairy products had findings showing antibiotics were detected in 60% of conventional milk samples whereas organic samples did not contain antibiotics. By testing milk straight off store shelves, researchers were able to uncover exactly what consumers are ingesting when they choose conventional or organic milk. An 18-month milk study in 2013 found that organic production enhances milk nutritional quality by shifting fatty acid composition.
Meta-analysis published 2016 in the British Journal of Nutrition, found that organic dairy and meat contain about 50 percent more omega-3 fatty acids. increase is the result of animals foraging on grasses rich in omega-3s, which then end up in dairy and meats.
. Meta-analysis published in 2014, in the British Journal of Nutrition, found that onions and organic crops had significantly higher antioxidants than conventional crops, including 19% higher levels of phenolic acids, 69% higher levels of flavanones, 28% higher levels of stilbenes, 26% higher levels of flavones, 50% higher levels of flavonols, and 51% higher levels of anthocyanines.
A ten year comparison study of tomatoes conducted in 2008, at the University of California, Davis, found that organic tomatoes have almost double the concentration of a beneficial flavonoid known as quercetin, compared with conventional tomatoes grown on an adjacent field. In a 2001 study published in The Journal of Alternative and Complementary Medicine, they look at already published literature to compare the nutrient content in five common organic vegetables versus “conventionally” grown ones. In organic carrots, spinach, lettuce, potato and cabbage there was significantly more Vitamin C, Iron, Magnesium and Phosphorus and less nitrates than the alternatively grown ones.
