When did you expose your child to peanuts? The changing advice of doctors…

peanuts2My first-born child is almost 12. When I was pregnant with her, the advice from the medical community was to stay away from peanuts during pregnancy and not to feed them to your child until the age of 2 or 3. Adhering to this, I did not eat any peanuts nor give them to my infant daughter. Fast-forward to when she was 18 months old, was having some symptoms that prompted food allergy testing — the results showed allergies to eggs, avocado and cashews (all of which I ate a lot of while pregnant), but not peanuts. Phew, I thought, at least not peanuts.

And then I still didn’t give her peanuts. We were avoiding all nuts due to her cashew and some other nut allergies, so giving peanuts seemed uncomfortable I guess. But two years after that first skin-prick test, at age 3 1/2, she tested positive for peanuts, after never having eaten one in her life.

Now, the medical community believes that was the problem — not being exposed to peanuts early in life. In fact, the current recommendation is to give your child peanuts (please consult your own doctor before giving your child peanuts). Our pediatrician told me that it is indeed strange to be giving the opposite advice to her patients than she had been giving for so many years.

The conclusions of a February 2015 study published in the New England Journal of Medicine were that “The early introduction of peanuts significantly decreased the frequency of the development of peanut allergy among children at high risk for this allergy and modulated immune responses to peanuts.” Studies of Israeli children had prompted the focus on the rates of peanut allergy here in the United States. It was hypothesized that that the very low rates of peanut allergy in Israeli children were a result of high levels of peanut consumption beginning in infancy because Israeli children begin consuming peanut-containing snacks (a product called Bamba) early in life. I was fascinated to learn that there is now a new peanut-based food product for babies called Hello, Peanut!, designed by a U.S. doctor to reduce the occurrence of peanut allergies in infants.

I would love to know — when did you give your child peanuts for the first time and does he/she have a peanut allergy?

  1. Hi Alison,

    Great question., Alison. Our journeys are very similar. I did not give my (allergic) son any peanuts, at doctor’s recommendation, as he had eczema, an early possible sign of food allergies when he was just an infant. Today, at age 13, he remains allergic to peanuts (although he has never had any) AND he Is allergic to a number of other foods which I ate a lot of during pregnancy (and while breastfeeding) such as cow’s milk, mustard and peas.

  2. We didn’t avoid peanuts when I was pregnant with my oldest child in 2010. I ate peanut butter all the time during pregnancy and breastfeeding, and she was diagnosed with peanut allergy at 7 months old. She broke out in hives a couple of times, and we noticed it was when my husband was holding her just after mixing natural peanut butter that had separated (apparently he’s not a very tidy mixer!). They only tested for peanut then because she was so young, but it was positive and she has since tested positive for a few tree nuts, including some she’d been exposed to and some she hadn’t. We cut out all peanut products right away and eventually became a nut-free house. I wouldn’t change anything about our approach given what the research is showing, but I don’t think early exposure to allergenic foods will prevent all food allergies…

  3. Thank you for your thoughtful and informative site. We just finished trick or treating, and I needed some ingredient information.
    My oldest daughter was exposed to tree nuts and peanut butter early on and has no allergies. For my younger daughter, we avoided tree nuts and peanuts, as doctors were instructing. My youngest is now allergic to peanuts. We have been avoiding exposure to tree nuts “just in case” but now I’m concerned we may be making things worse. I appreciate this forum and am curious about other people’s experiences.
    Thank you,
