What is a Food Allergy?
A food allergy occurs when the immune system mistakenly identifies certain food proteins as harmful and overreacts. About 6-8% of infants have food allergies.
Note: According to research, most food allergies improve with age. Milk, egg, wheat, and soy allergies naturally resolve in over 80% of children before school age.

|---|---|---|
| Milk | 2-3% | 80% (by age 5) |
| Eggs | 1.5-2% | 70% (by age 5) |
| Wheat | 0.4-1% | 65% (by age 5) |
| Soy | 0.4% | 70% (by age 5) |
| Peanuts | 1-2% | 20% |
