Chapter Soy (Glycine max) Allergens
Clinical reactions to soy are similar to those observed with cows’ milk or egg allergy. Soy allergy may affect the skin, the gastrointestinal tract, the respiratory tract, and cause systemic anaphylaxis (Sampson 2000). Food allergy to soy proteins has been described mainly in young children with atopic dermatitis, who often outgrow their soy allergy after 1-2 years of dietary elimination, and many soy allergies have resolved by 3 years of age (Sampson and Scanlon 1989; Taylor and Kabourek 2003; NDA Opinion 2004). Individuals with severe peanut allergies often also react to soy proteins due to structural similarities of the allergens of soy and peanut.
