Urban areas increase chance for allergies in kids
Children living in urban centers have a much higher prevalence of food allergies than those living in rural areas, according to a new study, which is the first to map children’s food allergies by geographical location in the United States. In particular, kids in big cities are more than twice as likely to have peanut and shellfish allergies compared to rural communities. Click to read more about the affect of allergies in cities.
The allergic potential of pollens is greater than we could have imagined.
There are pollens — and there are pollens, as scientists from across Europe discovered while investigating the allergic potential of pollens from the three main triggers of hay fever in Europe: birch, grass and olive. Different people can have very different allergic reactions to a particular type of pollen, however, and as the Hialine study researchers have now found, the allergenicity of the pollens also varies. Depending on the time of year and region, the pollens produce different quantities of protein compounds. These are ultimately responsible for the allergic immune reaction.
Up until now, the only way to ascertain how seriously patients will be affected is by measuring the airborne pollen concentration. However, this method gives very little indication of how aggressive the pollens are. Read more about the intensity of certain pollens.
