Those pesticides which correlated with lower IQ scores are currently sprayed on our nation's non-organic fruits and vegetables.
The research authors' solution? Wash your produce well. Well, how does one completely remove all pesticide residue from conventionally grown produce? Does any kitchen soap get rid of all the chemicals which have been sprayed on then soaked up by a fruit or vegetable? And would you even want scrub down all your fruits with Dawn?
Organic produce is guaranteed to come pesticide-free, as well as being free of fungicides, vermicides, GMO and a whole host of other unnatural chemicals which are applied directly to our food and wash into the water supply.
