Dry roasted peanuts may trigger allergy risk
Researchers say specific chemical changes caused by dry roasting process are recognized.
A new study reveals that dry roasted peanuts are more likely to trigger an allergy than raw peanuts.
According to researchers, specific chemical changes caused by the high temperatures of the dry roasting process are recognized by the body’s immune system, priming the body to set off an allergic immune response the next time it sees any peanuts.
They said this is the first time that a potential trigger for peanut allergy has been directly shown.
For the study, the researchers purified proteins from dry roasted peanuts and from raw peanuts.
They introduced the peanut proteins to mice in three different ways injected under the skin, applied to broken skin, and introduced directly into the stomach.
The mice that had been exposed to dry roasted peanuts generated greatly increased immune responses to peanuts, compared to mice that had been exposed to raw peanut proteins.
