What protein in peanut causes allergy?
The condition is associated with several specific proteins categorized according to four common food allergy superfamilies: Cupin (Ara h 1), Prolamin (Ara h 2, 6, 7, 9), Profilin (Ara h 5), and Bet v-1-related proteins (Ara h 8).
Why are peanut allergies so common now?
Here, we dig into the theories behind why nut allergies are so common. Possibly because most people now eat far more nuts and peanuts (which are not true nuts but legumes) than they used to. There is a genetic basis to many allergies, but some have to be primed before they have any real effect.

What is a Class 2 allergy?
Class 2 food allergens, such as apple and celery, are heat-labile, susceptible to digestion, and highly homologous with proteins in pollens. Class 2 FA (oral allergy syndrome, OAS) is typically the result of sensitization to labile proteins, such as pollens, encountered through the respiratory route.
Are there different levels of peanut allergies?
Manifestations of peanut allergy range from mild to severe, and risk factors predisposing to severe reactions are discussed. However, even in the absence of risk factors, peanut allergic individuals may still experience life-threatening anaphylactic reactions.
