Foods Involved

Key Messages

  • Milk and egg are the foods most commonly causing food allergy in young children, so careful dietary management is key to ensure normal growth and development
  • These allergies often resolve in childhood so testing is important to assess the continued need for dietary exclusion
  • Peanut and tree nut allergy also most often starts in infancy or childhood but new onset reactions can occur in adult life, although reactions to nuts in this group is more likely to be due to pollen-cross reactivity
  • Sesame seed allergy is increasingly common and usually presents in early childhood,
  • Pollen food syndrome (PFS), also known as oral allergy syndrome, is the most prevalent new onset food allergy in adults, and involves usually mild reactions to raw fruits, tree nuts and occasionally peanuts and some vegetables
  • Another less-common cross-reactive plant food allergy is called Lipid Transfer Protein allergy; it involves more severe reactions to both cooked and raw plant foods
  • Seafood allergy is the most common food allergy worldwide, with allergy to fish usually starting in childhood, whereas adults often present with new-onset reactions to shellfish
  • Wheat allergy often starts in early childhood and usually resolves in childhood, whereas adults can develop a wheat allergy, but symptoms may only occur when wheat is eaten in proximity to specific co-factors such as exercise, alcohol or pain relief
