"An allergy expert says almost every school in the country now has at least one pupil with a nut allergy - compared with a generation ago when this would have been a rarity."
"The number of children developing nut allergies has risen sharply - leaving schools with tough decisions about protecting pupils from potentially fatal exposure to food such as peanuts, walnuts, almonds and Brazil nuts."
"The Anaphylaxis Campaign, which aims to help people with allergies, says there are studies suggesting a threefold increase in the numbers of people with nut allergies since the mid-1990s. "
"But he says that research in Britain, the US and Canada has clearly demonstrated a steep increase since the mid-1990s. "

"400,000 U.S. kids allergic to peanuts
Regardless of the group's position, a growing number of schools have implemented bans. A recent survey of 1,174 U.S. districts by the Virginia-based School Nutrition Association found that 18 per cent of schools had peanut bans in 2007, a 50 per cent increase from two years earlier.
The increase in peanut bans corresponds to an increase in students diagnosed with peanut allergies. Between 1997 and 2002, the prevalence of peanut allergies in children under age five doubled, said Dr. Hugh A. Sampson, president of the American Academy of Allergy, Asthma & Immunology.
Today, there are 400,000 school-age children in the U.S. with peanut allergies."
As far as mathematics performance, I am referring to Canadian data. I don't know the methodology of the US data (nor how performance across all age groups - i.e. not just two grades compares to a decade or more ago).

"Former deputy prime minister John Manley said the results, which show that the math scores of Canadian 15-year-olds have dropped 14 points in the past decade, were on the scale of a national emergency.
