摘要

Broadly speaking, East Asians and Westerners suffer the same types of food allergies in about the same proportions. But there is an exception. Westerners are roughly twice as likely as East Asians to be allergic to peanuts. This is a puzzle-as is the question of why anyone is allergic to peanuts in the first place. A paper in the Journal of Allergy and Clinical Immunology sheds light on both matters. The study it describes, conducted by Quentin Sattentau of Oxford University and his colleagues, found that mice are more likely to develop a peanut allergy in response to dry-roasted nuts than raw ones. Since dry roasting is more common in the West than in East Asia, that may explain the disparity of incidence. And the chemical changes induced by dry roasting help explain what causes peanut allergy in the first place.
