What are the risk factors?

There are several 

  1. Family history. If food allergies are common in your family, you may be at risk.
  2. Other allergies. If you're already allergic to one food, you may be at higher risk of becoming allergic to another.\
  3. Age. Food allergies are more common in toddlers and infants. Children normally outgrow allergies to milk, soy, wheat and eggs. But nuts and shellfish are more likely to be lifelong.
