Roasted peanuts are less commonly eaten in East Asia - where peanut allergies are rare
Roasted peanuts are more likely to trigger an allergic reaction than raw peanuts, according to an Oxford University study, involving mice.
Scientists say chemical changes caused by dry roasting processes may prime the body's immune system - sparking future allergic reactions.
But much more work is needed before humans should consider swapping roasted nuts for raw ones, they say.
