IN MICE

which doesn’t translate to humans most of the time

Perhaps my understanding is not correct? Have we not essentially figured out that the increasing frequency of food related allergies is related to the topical application of food derivative proteins in a largely functionless manner in cosmetic and cleaning products? Baby body encounters new protein in wrong context (like peanut derivatives in a skin cream), arranges immune reaction, then later deploys that reaction when the child finally gets around to eating that thing rather than having it rubbed on its skin?

Is that model not well enough validated, or is my understanding flawed?

If this is the major contributor, isn't this an easily soluble phenomenon by subtraction, rather than addition?

Example sources:

And similar citations

Source for this? I was born with lots of allergies tested very soon after birth and they faded over time, the opposite of what the above theory would suggest.

I was just thinking about this the other day. How it would be awesome to go travelling without that constant anxiety in the back of my mind. that there’s a chance I could die at any second

Humanized mouse model. They translate pretty well.

I added example citations. You can find more with a similar search string, like 'topical proteins food allergy theory', which is what I just used.

it's the first I am hearing of your theory..

It seems like allergic reactions are far too varied to explain with one grand theory like this. It's more likely a list of causes ranked in order of occurrence or such, not just one main cause.

So SURE maybe there is some correlation with use of food in other products, but to assume that's the one big cause that causes all food allergies would be a massive leap of faith more than anything science would support.

If you search for your own bias you usually confirm own bias. Soo you're going to only find articles that support your view with a search string like that.

It seems suspiciously like one explanation to RULE THEM ALL to me, a common theme for the human mind, but not so much a good way to do science.

I know right? My spouse has a fish allergy. Not as immediately deadly as most peanut allergies but just from being near it she can still get swelling, irritation, and in extreme cases throat closing. She can't eat certain foods at many restaurants, cant eat at all at certain resteraunts, can't even go in some grocery stores or even walk down certain streets in bad areas. But we live in the Pacific Northwest so it's everywhere. Could we visit Japan? Probably not. Could we visit London? No idea. Fish and chips are popular there but I just don't know if its popular enough that you can smell it in the air.

Hopefully this kind of research continues to make breakthroughs for all allergies.

I hope this actually sees the light of day for people in the near future. This would be so amazing for my son.

Damn, I feel for her. Luckily I'm ok to smell it and only have a minor reaction. And it's pretty easy to avoid as long as you take some basic precautions. Fish I can't even imagine. Not even sushi...

I have a general allergy to most fruits in vegetable in different forms. Also constant pollen and dust allergy. Its probably a mild immune disease but if I could take a pill to just stop it I would try a banana or have a papaya salad

I would love to visit all these countries in Asia but with all the peanuts and the language barrier I'm too afraid to go.

There aren't all that many fish & chip shops in London or the UK. You could easily spend a week in central London and not see any of them. I'd definitely avoid fried food in any pubs though, as they often share a deep fat fryer.

We're so we sign up?

I relate to this so much. I also have a severe peanut allergy, can't go anywhere without some level of anxiety.
