"City kids are much more likely to have food allergies."
According to a study published in the journal Clinical Pediatrics, kids who live in urban centers are significantly more likely to have food allergies than rural kids. The study examined 38,465 children and found that 9.8% of children in cities had allergies, as opposed to 6.2% of children in rural areas. Oddly, peanut allergies were more than twice as common among kids in urban areas, with 2.8% of children in cities suffering from them (as opposed to 1.3% in rural areas). Allergies to shellfish were even more pronounced in city kids (2.4%, as opposed to 0.8% in rural communities).
