Are we sicker or has the Internet (and drug companies) simply made us more aware of being sick?E.g. There were always hyperactive (or ornery) kids but now they are ADHD. People have always had diabetes but they used to just die from it. Same with heart disease etc. However I do think the excess asthma and allergies we see are due to kids not playing outside anymore and the overuse of hand sanitizers etc.
I agree with ginnyrose on the concern over GMO foods. My 7 year old daughter seems to have serious allergic reactions to such foods. She's been hospitalized and there have been serious intestinal problems. After placing her on an organic wheat and gluten free diet she stopped having those reactions.
