New material Chapter 10What are organic foods?Are they healthier? Yes or no, why?"Current evidence does not support any meaningful nutritional benefits or deficits from eating organic compared with conventionally grown foods, and there are no well-powered human studies that directly demonstrate health benefits or disease protection as a result of consuming an organic diet, http://www.usatoday.com/story/news/nation/2012/10/22/pediatricians-organic-foods/1650013/
