Results of a study including adolescents of Västra Götaland, a Swedish County (pop. 1.5 million) born in 1992: 49 % of the teenagers suffer from physician-diagnosed asthma, nasal symptoms or atopic eczema. The allergies are more common among girls than boys. These allergies have increased by 10% since 2000. The study also points that those who eat more fish and butter tend to have a lower rate of asthma.
