Eight top allergens account for 90 percent of all food allergies. The 8 top allergens can be remembered by the mnemonic TEMPS WFS.
Two of the few studies showing a correlation between "inhalation" of food particles and allergic reactions consisted only of self-reported events. Please see the discussion below.
Skin contact and inhalation
Allergic reactions occur after ingestion. Skin contact or inhalation are unlikely to cause systemic reactions in food-allergic patients.
Contact urticaria to peanut is not uncommon but systemic reactions secondary to skin exposure are unlikely.
There is a difference between smelling a food and inhaling an aerosolized food.
In inhalation of aerosolized food, there is a contact between actual food matter and the respiratory mucosa in the nose and lungs.
Aerosolization of food can occur in boiling, frying, grating, shredding, grinding.
Inhalation of aerosolized food can induce wheezing in sensitive individuals.
