An interesting concept is that if you take your child to be tested for allergies, have you ever thought about asking the doctor, “when you are testing my child to see if they are allergic to corn, is it the version that has been implanted with insecticidal toxins to help the corn grow (that was introduced in the 1990’s) or is the corn source that has been in our food supply for 1000’s of years? There is a pretty good chance the testing doesn’t differentiate between GMO and non-GMO corn (or other products).
