AIBU to think peanuts should not be eaten on the Tube?

I was on the Tube yesterday and the man next to me had an open packet of peanuts which he was eating. It's such a common allergy and I know quite a few people, including my own brother, who would have had a serious reaction if they had been on that Tube.

Should I have said to him he shouldn't eat peanuts on thevTube even though I would not be impacted because I was worried about other potential sufferers in the carriage, as it's a very confined space and it was rush hour.

AIBU - It's a free world
YANBU - peanuts are a very common allergen and people should not eat them in confined public spaces.

That would be your choice. Do keep in mind though that no one tells the cleaners or cabin staff, or indeed the passengers, to refrain from eating peanuts in the clothes that they are travelling in.

Yeah, good point. I am actually a squirrel in disguise. 😀I eat a lot of nuts so there must be residue on all my clothes.

If it had been you with the allergy, fine to say something. As you weren't personally affected, 'telling him off' would come across as being a busybody.

If you feel strongly about this issue, you should raise it with TFL. As it stands, the man was doing absolutely nothing wrong.

The aerosol thing is a complete myth when it comes to peanuts, long debunked. The nut proteins (which cause reactions in allergic individuals) are too large to aerosolise. It just goes to show how poor allergy education is, even for many doctors. Lots of GPs etc haven’t got a clue and give out misinformation that goes on to wrongly cause major anxiety for sufferers and their families.

We ended up paying to see one of the best allergy consultants in the country for DD as she had become so nervous about going into anaphylaxis again. The relief when we finally saw him was huge and we were able to risk assess things a lot more clearly with accurate and up to date advice.

There is nothing special about peanut allergies other than the public obsession that they are somehow the worst/most dangerous allergen. This is totally incorrect and severe reactions can and do happen with any food. The most recent, heavily publicised anaphylaxis deaths in the UK have all been to milk.

But many of us have directly experienced airborne nut reactions. It does happen.

I don’t think you are allowed to eat food on the tube.

Of course you are allowed to eat food on the tube lol

Bubble567 · 24/07/2026 13:11

I have allergies to dogs yet people take them on the tube, they are allowed in shops and restaurants. It's very annoying but people just do whatever they like with no regard for others. I think it would be a good to dis-allow nuts on the tube but you'd have to bann loads of things such as pets, sesame seeds, other types of nuts, people are allergic to all sorts of things,not just peanuts. If someone is likely to have a severe reaction and risk of death then you'd think they would carry an epi-pen and things in place to help themselves.

I have severe peanut allergy in my family and I don't think peanuts should be banned anywhere.

We know the protein from peanuts doesn't travel far so airborne anaphylaxis isn't a thing. There's much more risk from someone eating peanuts and then touching things which are then touched by the person with the allergy. But they might have eaten the nuts at home or on the way to the tube.

It's very, very unusual for airborne particles to cause anaphylaxis in any allergy, it might cause a reaction ie hayfever from pollen but it doesn't cause life threatening reactions. Cooking seafood can be a bit more intense if you have that allergy.

This isn’t true for milk allergy. My daughter’s paediatrician said the risk of anaphylaxis from an airborne milk allergy is the highest. My daughter hasn’t had full on anaphylaxis from being in a coffee shop, but her breathing has been very bad and lips have gone blue. She just avoids them obviously and doesn’t eat out.

incidentally, my sister has a severe peanut allergy and has found it a lot easier to avoid peanuts in her 42 years than my daughter has milk in her 18!

Because it was an almond flour cake baking and there was an instant reaction when the door was opened.

that's not the same. for one thing its flour and not nut particles. For another there will be an actual strong directional gust of air coming from a hot oven when the door is opened. No one is saying its safe to throw peanut flour into the air and fan it at someone who is allergic

Tryagain26 · 24/07/2026 14:53

The problem is there are no many allergies.
I don't think the man was doing anything wrong. He wasn't feeding the nuts to anyone else and if someone is so allergic sitting next to some one eating nuts is going to affect them. They could move.
I say this as someone with a family member with nut, and dairy allergies. They are also allergic to perfumes and scented soaps but you can't stop people wearing perfumes or using soaps

RosieRR · 24/07/2026 15:25

YABU to ask for a ban but there is absolutely nothing wrong with explaining to someone close by what the problem is and asking them not to eat them! Just be polite.
Hopefully your child will have grown out of this by the time they want to go to the pub!!

The man was causing no problem. OP has no authority to go around telling people when they can eat nuts or not, especially when she’s not even allergic..! Total mountain out of a molehill

Livpool · 24/07/2026 15:51

I’m allergic to dogs (sets off an asthma attack) and they are fucking everywhere!

Seems some posters missed the word confined. 🤔, also lots of people touch the handrails, arm rests. Most tube journey are quite short so it is unusual to need to eat.

That’s not true. My commute to work can be an hour on the tube, from one end of the line to the other. Many, many people have similar commutes.

nocoolnamesleft · 24/07/2026 16:35

I love nuts. I work in healthcare. I never eat nuts before or at work. But that’s my choice.

Did you see Dr Adam Fox? His knowledge is incredible.

j would urge people on this thread to look up Dr Adam Fox on instagram. There is a lot of misinformation on this thread. As a parent of a now young adult with a life threatening milk allergy - which is an airborne substance - it drives me mad that everyone thinks nut allergies are the most severe. My daughter will never grow out of her milk allergy and she has a lifetime of anxiety ahead of her. She never eats out - we take all food on holiday. The only thing she will trust is McDonald’s chips and a m&s chicken and bacon sandwich. She can’t go away to live in halls at university. Her whole life is dominated by this. There have been mistakes over the years when she did eat out abroad which have meant we have had to use the EpiPens and She has been hospitalised and the risk is just too great. At one point it was touch and go whether she would live.

Please can we all work together to stop spreading the myth that peanut allergies are the only serious allergies. More people die of anaphylaxis to milk and this needs to be better understood.

Yes! We saw Prof Adam Fox (isn’t his Instagram account just brilliant!!) when she was younger and more recently have gone to his close colleague Prof Stephen Till now that DD falls under adult care. Two absolutely fantastic consultants, worth every penny. I found their explanations fascinating - you can just tell that both are leaders in their field. So kind & patient with DD as well.

I’ve never even considered this. I won’t eat peanuts on the tube again though!

I'm in this camp.

I would not have considered it unless mentioned (like now) its like one of those things thats so bloody obvious when said!

Viviennemary · 24/07/2026 17:22

It wouldn't ocvuf to me not to eat peanuts. But if somebody on the tube told
me not to eat them because they were allergic then I wouldn't, pubs and cinemas sell peanuts.

What child? The allergic person is the OP's brother, who may well be an adult and wasn't even there.

It was the front door of the house . Not the oven door.

But where does it end? A friend of mine has a life-threatening allergy to celery. Shall we ban all allergies in public, and basically at all times unless you can wash your hands and change your clothes straight afterwards to avoid touching something after you’ve eaten nuts, or have any traces on your clothes? It’s simply not practical/possible to ban all allergies from public spaces.

My husband has a severe pet hair allergy; should we ban all cats, dogs, rabbits, guinea pigs etc. My friend is allergic to seafood, so that's a number of food choices banned. Chuck in all the nut, wheat, and dairy allergies into the mix and what a messed up society we'd live in.
Allergies unfortunately need to be managed by the person with the allergy. We can all show some consideration, but let's keep it proportional.
