This month, we requested Dr. Julia Upton questions concerning the early introduction of allergens for the prevention of meals allergy.
I’ve launched allergens early and my child didn’t react. Can I test early introduction off my listing?
Congratulations for taking step one and introducing all kinds of meals. We’re encouraging “eat it early, eat it typically” to offer the bottom danger of allergy.
In Canada, meals like peanut are in our home mud so we’re uncovered to it by way of the pores and skin in tiny quantities. Even when not consuming it, our our bodies are nonetheless being uncovered to the meals. If the immune system solely sees the meals on the pores and skin, it may well make a mistake and suppose the meals appears like a menace that must be fought. This almost certainly happens within the first few years of life, though we’re nonetheless studying concerning the causes of the onset of meals allergy at later ages.
The easiest way to scale back the probabilities of the immune system making a mistake is to eat meals early and infrequently. This routine ingestion exposes the intestine to the meals protein and sends a message to the immune system that these proteins are certainly meals and never a menace.
As soon as my child has eaten the meals and there’s no response, how lengthy does it must be saved of their food plan to keep up tolerance?
We don’t for certain know the precise quantity of meals required, or what number of occasions every week, or for what number of years it’s required to eat a meals to attenuate the possibility of allergy. We do know from a serious research (LEAP and LEAP-ON) that early introduction and common ingestion of age-appropriate peanut merchandise till the age of 5 years is protecting towards peanut allergy. After age 5, even those that prevented peanut for a yr continued to tolerate peanut.
From these research the advice is to eat it early, eat it typically, outlined as age-appropriate serving sizes just a few occasions every week.
Though the LEAP research centered on peanut, we will apply the identical studying to different allergenic meals, similar to milk, egg, wheat, sesame, tree nut, soy, and so forth.
