Nitrogen fertilizer focuses way too much on the nitrogen part. It in fact causes heightened levels of starches which crowd out other nutrients, especially antioxidants. The antioxidant content alone of organic fruits and veggies means the equivalent of eating a couple extra servings a day(1)!
GMO foods actually cause stomach problems, autoimmune issues, and even have a xenoestrogen which mimics estrogen. That will result in fertility issues(2).
Commonly cheaper price tags in stores are NOT representative of the real costs of GMO and conventional foods.
