Non-organic fruits and vegetables are grown with synthetic pesticides and fertilizer. Studies show that more than 90% of children in the U.S. "have detectable residues of at least one neurotoxic pesticide in their urine." Neurotoxins are poisonous to your brain and nervous system.
Pesticides have been found to change hormones and reproductive systems of animals in the wild. A lot of our human systems are similar, so they must be hurting us too. These chemicals are considered hormone mimics and endocrine disruptors.
According to a study outlined in a 2003 Environmental Health Perspectives article, children "eating organic fruits and vegetables had six times lower levels of pesticide byproducts in their blood versus children eating conventional produce."
Choosing organic foods also provides more nutrients. Mother Earth News reports that organically raised chickens lay eggs that contain:
* 1/3 less cholesterol
* 1/4 less saturated fat
* 2/3 more vitamin A
* 2 times more omega-3 fatty acids
* 3 times more vitamin E
* 7 times more beta carotene
There are more than 30 studies comparing the nutrient content of organic crops and those produced conventionally with chemical fertilizers and pesticides. In these studies, various individual nutrients in individual crops were compared, such as zinc in organic versus conventional carrots, or Vitamin C in organic versus conventional broccoli. In the more than 300 comparisons performed in these studies, organic crops had a higher nutrient content about 40% of the time.
For three individual nutrients, Vitamin C, nitrates and protein quality, there is enough evidence to suggest that organic crops are superior to conventional ones. Compared to crops grown with chemical fertilizers and pesticides, organically grown crops generally have a higher Vitamin C content, a lower content of carcinogenic nitrates and better protein quality.
