There are plenty of foods out there that state on the label that then are NON-GMO foods. I go shopping all the time for ME & those are the labels I look for on the foods I buy so that's NOT an excuse for not eating.

I am also cautious about the preservatives in the foods I buy & make sure I don't buy anything with MSG in it...many Chinese foods have MSG in them....but more & more aren't using them.

Paranoid feelings that sometimes can come with schizophrenia might possibly be adding to your feelings about the foods? Though there are many times when shopping that I look at the labels & realize I don't want to buy what looks good because of what's in it...it's a normal concern these days also.
