> A study from the Jaffe Food Allergy Institute at New York's Mount Sinai hospital found that from 1997 to 2008, peanut allergies tripled from 1-in-250 children to 1-in-70. Someone who has more knowledge in biology correct me if I'm wrong, but it's virtually impossible for this to be "hereditary" issue with such a drastic change in such a small amount of time, right? I think it's much more likely to be something either related to diet (the types of foods found in the supermarket) or environmental (local pollution/dirty water, etc sources causing it).
