What is the significance of the timing of peanut introduction to infants?

  1. It has no effect on allergy risk

  2. Late introduction increases risk of allergy

  3. Only raw peanuts should be introduced

  4. Allergic reactions can occur immediately

The correct answer is: Late introduction increases risk of allergy

The timing of peanut introduction to infants is critical because research has shown that late introduction of peanuts increases the risk of developing a peanut allergy. Studies have demonstrated that introducing peanuts in the first year of life, particularly between 4 to 6 months, can significantly reduce the likelihood of an infant developing an allergy to peanuts later on. This relationship is rooted in the understanding of oral tolerance, which suggests that early exposure to allergenic foods can help the immune system learn to tolerate those foods, reducing the chances of an allergic response. Not introducing peanuts until later in childhood can prevent this tolerance from developing, thereby heightening the risk of an allergy. By focusing on this timing aspect, caregivers can implement dietary practices that not only foster healthy eating habits but also potentially safeguard infants against future allergies.
