I have four kids, all born in the US where we lived for the last 14 years. All had developed food sensitivities in the US. I was raised in CH, never had any allergies, but started having bad hay fever at age 26 after moving to the US (it got really bad every summer when coming to visit Switzerland). We now have moved back to Switzerland and this is the first summer I had no allergies since I had left Switzerland 14 years ago. My kids' food sensitivities seem to have disappeared completely over the last 4 months that we have lived here.
Our neighbors here who lived in the US until 2 years ago said that their son's asthma has disappeared since they don't live in the US any more.
Has anyone had similar experiences? I know that the genetically modified foods in the US cause a lot of harm and possibly food allergies. Is it possible that there are other toxins making people sick over there and not here? (Thinking of heavily chlorinated water in the US for example).
