Causes of Food Allergies

Food allergies occur when the immune system mistakenly identifies a harmless food protein as a threat and mounts an attack. The exact cause of food allergies is not fully understood, but several factors are believed to contribute:

• Genetics
  • A family history of allergies increases the risk of developing food allergies.

• Environmental Factors
  • Early exposure to allergens and changes in diet and lifestyle may influence the development of food allergies.
• Hygiene Hypothesis

• Age
  • Food allergies are more common in children, though they can develop at any age.
