A decade after a landmark study proved that feeding peanut products to young babies could prevent development of life-threatening allergies, new research finds the change has made a big difference in the real world.

Peanut allergies began to decline in the U.S. after guidance first issued in 2015 upended medical practice by recommending introducing the allergen to infants starting as early as 4 months. The rate of peanut allergies in children ages 0 to 3 fell by more than 27% after guidance for high-risk kids was first issued in 2015, and by more than 40% after the recommendations were expanded in 2017.

    Unfortunately, this strategy didn’t work to prevent my kid from having the same milk allergy that I do. In fact, it’s worse.

    Not fatal or anything. His lips become bright red, swelling slightly and peel later, he obviously gets days of the shits, and if it’s repeated exposure he will get rashes all over. And we’re talking some small amount of milk powder or unexpected butter deep in the ingredients of a baked good - if he actually consumed something like real milk, butter, or cheese, it would be much worse.

    Goat cheese seems fine. It’s something about the cow milk proteins.

    For me, it’s just a serious case of the shits when it’s the real deal. I guess my millennial upbringing of a glass of milk daily conditioned some small amount of tolerance.

      Obviously nowhere near that extreme, but I know a shockingly large number of millennials (and not just the Asian babies) who, for one reason or another, had soy or nut milk as a baby, dairy milk almost our entire lives, and then realized we were lactose intolerant like late 20s/early 30s.

      It, again, is obviously not that extreme. But there is very much the idea that being gassy and having “weird poops” was normal because… it was. In the sense we were constantly poisoning our bodies.

      It always makes me wonder about a friend who talks about how peanut butter “makes me puffy”. Is it just a body reaction to the high fat content or is it a mild allergic reaction?

        you can gain lactose intolerance later in life, or produce less galactase to be able to break it down.

        its not inherently what youre born with.

        Im definitely of the group whose tolerance has decreased overtime.

          I mean literally noone is born lactose intolerant. You’d just starve.

          Genetic lactose intolerance develops some time later through a variation in gene expression. But the effects of lactose intolerance also vary more than that, because if you continue to consume milk your gut biome changes to reflect the abundance of nutrients.

        It’s also possible for lactose intolerance to get worse as you get older - I say, as a 40+ year old who has had to cut milk out of his regular diet to have normal poops again.

        That’s how lactose intolerance works. You start out getting milk from your mother, you don’t become intolerant usually until the end of puberty.

    East Asians have a lot of peanut products in everyday meals so the allergy is nearly non-existent in East Asia. It was some dumbass suggestion to stop pregnant mothers from consuming peanut products or expose babies to peanuts that caused all this.

    This has given me an idea. I will avoid giving my children any crystal meth, in the hopes they will become allergic to it.

    I would think that if both parents were highly allergic, you might want to give baby that first taste of peanut butter in a medical setting.

      First exposure, even if anaphylactic is not as bad or life threatening. Second and subsequent exposures are rapid and pronounced.

      So, if they are super high risk, then that is a good idea, but it’s not as important as avoiding nuts for someone with a previous exposure that caused a reaction.

    There was a science versus podcast on this a few years ago. One of the ideas was that if a child makes contact with peanuts through skin prior to eating it, then they’re likely to have an allergy. That always confused me. Anyone have any more information on this?

      i would think the more allergic you are the more sensitive to peanuts touching the skin, instead of a person only getting a reaction from eating it. if you have chronic allergies to something, you can have your IGE levels checked, although its not part of a normal test. anything over 1000(concentration of IGE levels) puts you susceptible for allergic rhinitis, asthma or atopic dermatitis, the higher it is, the more severe the “trifecta of allergy is”.

      and also susceptible to allergens too of the skin. food specific might be very different though.

      its only when its >2000 its a different disease altogether( a very rare immune-allergy disease)_

        There’s a lot in your comment that I don’t know much about, but the point the podcast was hypothesizing was that how contact with peanuts occurred first determined whether someone was allergic to them at all. So a baby that ate something containing peanuts did not have allergies to them, but a baby whose first exposure was somehow dermatologically was more likely to develop severe peanut allergies.

        Again, it’s the only time I’ve heard that, but I thought it was really interesting and so was asking if anyone had more information. Thank you for the reply!

    Israeli people feed Bamba snacks as a first food to babies and have almost no peanut allergies. Bambas.are basically peanut butter Cheeto like puffs. I introduced peanut butter super early on with mine, because of the allergy thing, but I wish I knew about the Bambas. My friend gives them to his daughter and she loves them. I don’t know if a non Israeli equivalent exists for people avoiding supporting that country, but they are a great snack for babies.
