True or False: Early introduction of peanuts can decrease the risk of developing a peanut allergy.

The statement is true because research has shown that the early introduction of peanut-containing foods can significantly reduce the risk of developing a peanut allergy in children, especially when introduced between 4 to 6 months of age. This finding aligns with guidelines released by health organizations such as the American Academy of Pediatrics, which recommend introducing allergenic foods, including peanuts, to infants early rather than delaying their introduction.

This approach is based on the "hygiene hypothesis," which suggests that early exposure to certain allergens may help to develop immune tolerance, thereby preventing allergies from forming. By incorporating peanuts into the diet of infants—preferably in a safe, age-appropriate format—parents can help mitigate the chances of sensitization and allergy development later on.

In contrast, the other options suggest limitations based on age or family history, which do not encompass the broader guidance of early introduction. The evidence primarily supports early introduction without necessarily restricting it to specific age groups or children with a family history of allergies. This understanding contributes significantly to current practices surrounding allergenic food introduction.
