Organic nutrition

Hello, my name is Amy and I'm a college freshman doing a paper on organic food. I've been doing reasearch for this topic and I came across your site. I noticed you said that organic food had more "vitamins, minerals, enzymes, and trace nutrients" than food grown in pesticides. According to my other sources, though, I found that they can't tell if there are more nutritional values of organic food besides there being more vitamin C. I was wondering if you could tell me where you got your information or how you came to that conclusion. Help would be greatly appreciated.
