A mice study conducted by Oxford University researchers has found that roasted peanuts are more likely to trigger allergic reactions than raw ones.
The researchers exposed the mice to proteins in the peanuts either through skin or the stomach. They report that mice exposed to dry roasted samples had a stronger immune response as compared to mice exposed to raw peanut samples.
"This is the first time, to our knowledge, that a potential trigger for peanut allergy has been directly shown," lead researcher Prof Quentin Sattentau told the BBC. "However our research is at an early stage and we think that it would be premature to avoid roasted peanuts and their products until further work has been carried out to confirm this result."
The research appears in the latest issue of the Journal of Allergy and Clinical Immunology.
