Dec. 3, 2012 -- People exposed to higher levels of certain germ- and weed-killing chemicals may also be more likely to develop food allergies , a new study shows. The chemicals are called dichlorophenols (DCPs). They are created by the breakdown of common pesticides, including chlorinated chemicals used to purify drinking water. They also turn up in moth balls, air fresheners, deodorizer cakes in urinals, and certain herbicides sprayed on crops. "They're quite common," says researcher Elina Jerschow, MD, an allergist at Montefiore Medical Center in the Bronx, N.Y. Doctors don't know why, but rates of food allergies are rising in the U.S. A 2008 study by the CDC found an 18% jump from 1997 to 2007. Jerschow wondered if increased protection from germs might somehow be lowering the body's tolerance to foods.

Oct. 5, 2012 -- Some natives of Louisville, Ky., needn't be surprised if they're sneezing while reading this article. Their city tops the list this year as the worst place to live in the U.S. for fall allergies . To earn the No. 1 spot, Louisville received a "worse than average" rating for its pollen counts and allergy medication use by each patient. But it got a "better than average" rating for the number of allergy specialists available in the area. Last year, Louisville placed sixth in this annual ranking of 100 metropolitan areas done by the Asthma and Allergy Foundation of America (AAFA). In all, six Southern cities made the country's top 10. Sacramento, Calif., was named the best place for people with autumn allergies to live. The rankings are based on an analysis of three key factors: pollen and mold scores during fall 2011, the number of allergy medications used by people with allergies last fall, and the number of board-certified allergists per 10,000 patients. This year's 10 worst places for fall allergies are:
Oklahoma City, Okla.
Baton Rouge, La.
This year's five best places for fall allergies are:
Daytona Beach, Fla.
San Francisco, Calif.
