Oily Fish Lowers Allergy Risk
New research from Sweden suggests that children who regularly eat oily fish, such as salmon, may have a reduced risk of allergic rhinitis--inflammation of the mucus membrane inside nasal passages.
To conduct their study, researchers at the Karolinska Institute in Stockholm had parents and kids complete questionnaires detailing how often the children consumed 98 foods and beverages common in Sweden. For fish, they were asked specifically about oily varieties such as herring, mackerel and salmon, as well as less oily alternatives like codfish, Pollock, pike, tuna and fish fingers. Within the group, 19 percent of the children indicated that they had symptoms of rhinitis. Of the children who didn’t have rhinitis at age eight, 21 percent developed allergic rhinitis and 15 percent developed non-allergic rhinitis by age 16.
The results suggested that eating oily fish dropped the risk of developing allergic rhinitis by roughly half. The researchers noted that fish consumption during pregnancy or even during infancy could have influenced the results, but these factors were not measured.
Experts not involved with the study pointed out that young children who regularly eat salmon may generally follow healthier diets.
