Why It’s Rare in East Asia

1 Peanut Allergy May Be Due to Dry-Roasting

The source of peanut allergies may be not so much the peanut itself as how and whether it is cooked. Researchers at the University of Pennsylvania and Oxford University performed a series of experiments with mice and determined that those exposed to dry-roasted peanut proteins developed a much stronger immune system response, an indicator of an allergic reaction, than mice exposed to raw peanuts, and that their heightened allergic reaction persisted for peanuts whether raw or roasted. Researchers suspect that dry roasting alters “the physiochemical properties of peanut proteins,” and that this may explain why peanut allergies are far more common in Europe and North America, where peanuts are usually eaten roasted, than in East Asia, where they are typically eaten raw, fried or boiled.
