The researchers analyzed information from 8,306 children and adults whose blood samples were taken as part of a national health survey in 2005 to 2006. About 9 percent of participants had an elevated levels of antibodies to peanuts, indicating they had the potential to be allergic to peanuts.
Turns out the children from higher income families tended to be allergic to peanuts. The proposed reason?
The results add support to the hygiene hypothesis, said study researcher Dr. Sandy Yip, of the U.S. Air Force. The hygiene hypothesis is the idea that living in a cleaner environment may make people’s immune systems more sensitive, and increase the prevalence of allergies.
Huh? Are they assuming that lower income people are less hygienic? That’s a leap, in my opinion. However, they continue:
The findings are also inline with those of a study published earlier this year, which found children living in cities were more likely to have food allergies compared with those living in rural areas, which tend to be less expensive than cities.
The study was presented this week at the American College of Allergy, Asthma and Immunology meeting in Anaheim, Calif.
I’ll have to ponder this one a bit… I sense a leap in logic, perhaps a correlation/causation situation… something just doesn’t taste right. But that’s just me.
