Who’s allergic or intolerant to Quorn (mycoprotein) ?

93 replies

QuestioningQuorn · 25/09/2025 21:04

Inspired by a few threads of late; who is allergic or intolerant to Quorn? Or unbranded it is called mycoprotein.

I am. Took a few times to figure it out (TMI - projectile vomiting about 6 hours later). And have been subsequently caught out a few times eating as a guest.

It sent me down a rabbit hole about mycoprotein. Some studies say it is a more common allergen than even peanuts; yet many haven’t been exposed to it enough or ever for it to be commonly known yet.

So I checked the school dinners and it’s on there 3 times a week; plus ‘Plant x’ which no idea what that contains so potentially all of the meals. Should I be asking for no Quorn options for my kiddo? The more you eat it the more likely sensitivities and then allergies develop. And they can do rapidly and quite severely apparently. I avoid it as much as I can! Is this sensible for my kids or is this crazy parent realm?

Yes I am. Severe vomiting. Dr had to give anti emitic injection as v dehydrated.
Also allergic to penicillin

Sharona39 · 26/09/2025 04:08

Yes! After eating it I had projectile vomiting and felt like I was going to spontaneously combust,as I was so hot.
A good few years later I thought I would try some again.
Same result occured. 🙅‍♀️

Another one intolerant to Quorn. Had to take several days off work as a result of the last excruciating episode. Couldn't hold down water for days. Mushrooms too, very sadly.
My dd has a penicillin allergy. I'll make sure she avoids Quorn.after reading this thread.

DumpedByText · 26/09/2025 03:15

I'm allergic to it as well, makes me vomit a lot! I'm not veggie anyway so easy for me to avoid.

I used to eat it lots but I started to get bloating, cramps and wind after eating it, the symptoms gradually got worse until it was like full blown food poisoning so I stopped eating it. I'm also allergic to penicillin interestingly.

Yes, I am too. And erythromycin

It causes me to bloat like a helium balloon and have ‘digestive urgency.’ I used to like a Quorn sausage too, removed the element of mystery meat, shame.

I am intolerant to it. It gives me stomach cramps and diahorea As is my daughter. It’s meant my daughter won’t eat at school as they do not clearly label food nor are they honest. The chicken wrap for instance is chicken unless they have run out at which point they start shoving the vegan chicken in - (waste not want not) without telling the kids. My daughter knows because she later feels pain (and the embarrassment of the shits in a school toilet)

Wow that’s really not on! It can kill people!

It's so interesting to hear how many people have made a link between penicillin allergy and Quorn.
We are a veggie family, myself and DC2 don't like it, my mum and DC1 can't go anywhere near Quorn. Both are allergic to penicillin! I've never come across this before

TheSpiritofDarkandLonelyWater · 26/09/2025 00:00

Not me but my grandad was. My mum made him cottage pie from Quorn one time and that is how they found out.

ButterPiesAreGreat · 25/09/2025 23:59

I stopped eating about 10 years ago, as it was making me uncomfortably gassy. Nothing worse but as I have other allergies, one of which nobody has been able to pin down but regularly gives me hives, it was better to stop.

LemondrizzleShark · 25/09/2025 23:51

DH gets awful stomach cramping from it. I’m fine with Quorn but react to Beyond Meat - don’t know what is different ingredient-wise.

Cauldron sausages FTW.

Wiseplumant · 25/09/2025 23:36

I am ,quorn on the twice I ate it made me . threw up violently .

BeautifulNights · 25/09/2025 23:32

My cousin can’t eat quorn, but then he can’t eat quite a few things, beef, pork, tomatoes, egg. That’s the only person I know who can’t eat quorn and I know a lot of vegetarians/vegans who eat quorn once a week or so.

Blessedbethefruitz · 25/09/2025 23:27

I cant eat quorn. I used to but the results were worse each time, severe pain and diarrhea. Like pp im also anaphylaxis allergic to penicillin, asthmatic, and have random other allergies. Currently under investigation for IBD also. Very weird.

Edit - i know of an older man (former boss) with the same quorn/meat substitute reaction as me too. And it's served at my son's school several times a week, although he never wants it.

RitaFromThePitCanteen · 25/09/2025 23:17

Me. Had it twice. Both times gave me diarrhoea (sorry for the TMI). I don't understand how I've ended up sensitised to it because until then I'd never had Quorn before.

50Balesofgrey · 25/09/2025 23:02

Not allergic, but it's way too processed.

A couple of years ago I was all alone with my daughter and baby and I ate it…face swelling eye itching and my throat felt like it was narrowing…had sister get some pills from the chemist for allergic reactions…honestly thought I was going to die…never had it again. I’d rather have proper veg as a sub.

Gosh you definitely need to visit the doctor about that and maybe get an EpiPen? (Do they work on this?!)

It’s really easy to eat this accidentally unfortunately and as some say subsequent reactions can get quickly worse. Please don’t leave that.

It can’t be classed as an allergen if it’s the main item for 3 - potentially all meals in school dinner V / VG option.

@34ransum

No it’s an open menu. So each morning the teacher brings the menu and asks what they want. I just looked and unfortunately the Quorn is dressed up quite appetisingly that my 3 year old would choose it in all likelihood on numerous days. Ie. Quorn Hotdog, ‘Quorn burger’ ‘Quorn Dippers’. He’s just going to hear hotdog, burger and dippers here.

Show quote history

It’s also an ultra processed food, I do eat it and like it but wouldn’t eat it 3x a week. It gives dh an upset stomach.

MargaretThursday · 25/09/2025 22:58

My Brother has the same reaction, and worse each time he's had it.

jonthebatiste · 25/09/2025 22:56

I’m not allergic to anything except codeine, but quorn and every meat substitute I’ve ever tried give me the runs and a headache. I eat mushrooms regularly.

Murfmeister · 25/09/2025 22:53

I can't eat the stuff either...very bad stomach reaction.
