One of my favorite viners and super knowledgeable foodies, CuriousG seeded this story from another source a few days ago, but Rodale has some wonderful resources that might get used if we get more than two folks reading it this time!
No one knows what causes food allergies—they're one of the great mysteries that science has yet to solve. But it's doubtful that any allergist had suspected that your lawn, or your tap water, could be the cause.
That could change, based on the findings of a new study published in the Annals of Allergy, Asthma and Immunology. The authors found that a breakdown by-product of a pesticide used on genetically modified crops, lawns and golf courses, and of chlorine-treated drinking water, was associated with higher rates of food allergies.
