Food allergies are on the rise globally, with around 32 million people in the U.S. diagnosed. New Swedish research indicates that exposing infants to diverse foods during their early months may lower allergy risks. Specifically, children who had 13–14 different food exposures by 9 months showed a 45% reduced risk of developing allergies compared to those introduced to fewer foods. The study emphasizes the importance of early and varied diets but notes uncertainty about the timing and benefit of introducing other allergenic foods.
However, there is more uncertainty about timing and diversity of other allergenic foods.
The researchers observe a high-certainty evidence that early introduction of egg and peanut is associated with reduced egg and peanut allergy, respectively.
Children who tried 13 to 14 foods by 9 months decreased the odds of food allergy by 45% compared to those who ate 0 to 10 foods.
Interestingly, no association was seen between diet diversity at age 6 months and food allergies at age 18 months.
