Have Peanut Allergy? You May Also Have Other Food Allergies, Thanks to Cross-Reactivity

According to recent research, an allergy to one particular food may also trigger allergic reactions to another food through a phenomenon known as cross-reaction.

It is estimated that 4-8% of children and 1-4% of adults have at least one food allergy, with the most common allergens being peanuts, tree nuts, fish, shellfish, dairy, wheat, eggs, and soy, though more than 170 different foods have been known to cause allergic reactions. In addition to these allergens, there are a number of foods that may cause symptoms through cross-reactions.

Cross-reactions study from Norway

Research on mice by doctoral candidate Nina E. Vinje focused on the legumes lupin and Fenugreek. Her research resulted in a model that can be used to test whether legumes – such as peanuts – can trigger allergic reactions in mice that already have allergies to Fenugreek or lupin. Both lupin and Fenugreek are allergens which have been found widely in processed foods over the past decade, and they have been found to cause serious cross-reactions in people who are allergic to peanuts.

By studying mice, Vinje and her team of researchers hope to gain insight into the clinic reactions associated with food allergies involving cross-reactions, in order to better understand these reactions in humans.

The research project was carried out at the Norwegian Institute of Public Health, with researchers from the Norwegian Veterinary Institute and the Norwegian School of Veterinary Science, and the results have recently been published byScience Daily.
