Nuts...why are they so bad

Nut allergy

Can someone please explain the fact that 54 years ago I started school and did 14 years without meeting anyone allergic to nuts...now everyone is and I can't enjoy a snickers without feeling guilty.

It is actually a serious question how we have got to the situation where so many people are in trouble if I open a packet of dry roasted.

I grew up in the 60s and 70s. We simply didn't eat nuts much. The bars I remember didn't have nuts in them for the most part. Maybe hazelnuts, but peanuts weren't included in everything.

I wonder too if the predeliction of urban forest planners for male trees has affected our allergic response - male trees spread a huge amount of pollen, which may sensitise people.

I could be dead wrong.

True. Nuts were a Christmas treat. And peanuts were in chocolate which was more of an adult thing. We also had jam rather than peanut butter.

My daughter has eaten nuts most of her life and developed a brazil nut allergy aged 11 after having previously eaten them before.

Interesting. This can happen if you have a break from a food then when you eat it your immune system recognizes it and fights it. Like how it's the second beesting that gives you an allergic reaction.
I remember children getting hives from strawberries as we only had them for a couple of months during summer. Don't seem to see hives now, probably because fruit is available year round in some form.

On Spotify the Zoe science podcasts are excellent, interviewing cutting edge scientists (not influencers!) they have just done one on allergies with a British professor who explains the change in rates well worth a listen

What I hadn't realised with nuts is that often the person with the allergy doesn't have to ingest them personally. I was told (though have not researched/verified) that reactions can happen from airborne particles, or touching something which has recently been touched by someone who has been handling nuts. So in a playground for example, child a eats their snickers, gets peanut residue onto their hands then uses the rails to climb the stairs to the slide. Child b is next on the slide, puts their hand on the nutty rails, touches their face and that's enough!

So I assume with more awareness comes more rules and restrictions

Also there's genuinely double the number of people on the planet than there were 50 years ago so your interpretation that there's more of it about is not inaccurate.

Egg allergy is like that as well.

SweetnsourNZ · 23/05/2026 17:26

I'm not allergic but was prone to coldsore breakouts. Someone told me peanuts cause it so I took them out of my diet and haven't had one since. Apparently they repress a mineral, can't remember what its called but begins with L.

Aethelred · 23/05/2026 17:25

My daughter has a peanut allergy. She would probably have died during her first reaction as a toddler a few decades ago but survived because of modern medicine and awareness of the issue. When she first had it we poured modern antihistamine down her throat which saved her life (it was touch and go with her breathing) and we knew it was an allergic reaction. It may well have been put down to a different cause in the past.

johnd2 · 23/05/2026 17:24

My son ate nuts, eggs, fish and more from weaning, and we ate them regularly before that,, no rubbing things on his skin or any other weird stuff, and it was all fine. It was only at 1 that he suddenly became allergic and had to get an EpiPen. He absolutely loved fish and seafood so it was a real shame that he couldn't have them any more.
So I think all this information about experiencing things through the gut first or not having things until age 2 is universally true.
No other food allergies in the family, just him.

@shazshaz I developed hayfever in my teens and the only summers I didn’t have it after that was when I was pregnant

You were lucky. I, like many got it worse when pregnant and you can't take anything for it during pregnancy.

SweetnsourNZ · 23/05/2026 17:17

I was a new mother when these guidelines came in. We were also told to avoid egg white. Just recently they have changed it back to the old way. Can't remember being told to avoid them in pregnancy though. Allergies were already rising though even then.

Peanuts were avoided anyway as they are a choking hazard and can cause pneumonia if inhaled.

SweetnsourNZ · 23/05/2026 17:17

Fluffybuns88 · 22/05/2026 22:59

There's a scientific reason for this!

Up until the early 2000s women were told to avoid nuts in pregnancy if they had certain health conditions like asthma, up until 2015 parents were told to avoid giving children any nuts until 3 years of age.

Studies now show that starting at 6 months and giving them regularly reduces allergy likelihood by over 80%.

54 years ago a lot of them will have died before they made it to school age.

SooticaTheWitchesCat · 23/05/2026 16:56

I know someone who did a study on this. I can’t remember what outcome was completely but there was a connection between the rise of allergies and pollution and also of high cleanliness standards.
the cleaner you are the more likely you are to get allergies.
it’s very interesting. I didn’t know anyone with a nut allergy when I was a child either.
A friend from South Africa said it’s practically unheard of out there too, which makes you wonder why.

imaravenGRONKGRONK · 23/05/2026 16:55

Loads of people have airborne reactions, surely. My friend’s husband couldn’t be in the M&Ms store in London because of his allergy and I was reading a journal article recently about allergy parenting and they cited the case of a child with an airborne wheat allergy who couldn’t go near the bread aisle in supermarkets.

One of my DC has anaphylaxis and I am thankful that it isn’t airborne!

Yes this. We have done it to ourselves. And the western trend for avoiding particular foods in pregnancy and when weaning is travelling across the world and there are growing numbers of allergy sufferers in countries that tradtionally have high intake of nuts and other allergens because they are avoiding them too.

Airbourne reactions are incredibly rare and ar worst cause a minor reaction. No one has ever died from it. I’m shocked up thread someone’s kid was hospitalised due to it, aybe the only person ever.

If you’re talking about my post about my DB he’s actually had a reaction to airborne particles more than once and been hospitalised twice, the second time they could barely get oxygen in as his airway was so swollen they thought they were going to have to give him a surgical airway so about as far from a ‘minor reaction’ as you can get. It is a bit different as in the first 2 instances they had been burning peanuts in the room a while before he came in so there would be a greater amount of particles in the air but his consultant has advised that it’s absolutely not worth risking it on a plane now that he’s had such a severe reaction he’s more prone to more.

Thank you for taking time to reply. It's good to feel some validation that having never had digestive problems all my life, since I started eating beans, seeds and nuts things have become quite bad. I reckon my system is not geared up for them.

Many people’s aren’t but it doesn’t fit with the modern ‘plants are best’ mantra.

Good luck moving forward.

KnittyKnotty · 23/05/2026 14:59

There was one girl in my school (1990's 300 pupils) who suddenly developed a severe peanut allergy. Full blown anaphylaxis nearly died etc.

The school didn't do anything about it, she was basically left responsible for avoiding nuts while we were chomping on Snickers from the vending machine. Totally crazy there was no total ban put in place, thankfully taken more seriously these days.

I think their must be a TUI crew member at Newcastle with an allergy as just about every flight I've been on in the last 10 years or so has had an announcement that nuts are banned on that flight.

Perrygreen · 23/05/2026 14:52

Yabu-ish.
A lot of those people who choked on nuts actually had anaphylaxis.

Recently there was also the
misguided guidelines for introducing nuts later and weaning quite late.

I used to work in an office with something severely allergic to nuts. He was out one day, so a visitor used his desk. The next day he came in, wiped down his desk and equipment and still had a reaction almost soon as he’d sat down. The visitor was there again, and it turned out he’d had peanut butter on toast for breakfast the previous day. We could only imagine that traces of peanut butter were on the mouse/desk/chair.

Also, we didn’t eat as much massively processed food containing peanuts/groundnuts and the oil as much in the 70s, 80s & 90s.

You can do your own research as lots online but you are by no means the only one who has issues with nuts, or indeed, other supposedly healthy plant based foods. Beans , nuts, seeds etc. are all used by plants to reproduce and therefore have evolved strategies not to be fully digested.

Nuts are very high in omega 6 which is a known driver of inflammation. They also contain phytates, oxalates, lectins & tannins which are known mineral chelators. So not only do we struggle to absorb the minerals from them but they can actually deplete us of minerals. Oxalates are the worst as they build up in the body over time - see Sally Norton for more info.

Nuts also are often grown in areas that are heavily sprayed with synthetic fertilisers and pesticides which are directly toxic.

Some nuts contain high levels of FODMAPS which can trigger IBS etc.

I would love to believe that nuts are healthy but my body and what we know about them tells me otherwise. Some people may do well on them but I don’t as do many others.

mrsbowes · 23/05/2026 14:40

Nuts aren't particularly bad, all allergies are increasing.

Probably multiple reasons - changes in the way food is cultivated, grown and processed.
More chemical exposure.
Cleaner homes.
Fewer parasites to battle so our immune systems overreact to food
More people with allergies, asthma and eczema surviving to adulthood to pass on their genes

imaravenGRONKGRONK · 23/05/2026 14:28

My great grandfather had what I would now view as an anaphylactic reaction to shellfish - but back then everyone thought it was his asthma, and because the adrenaline that he had to carry (he had very bad asthma) seemed to work in either case, he was never diagnosed. Just had asthma attacks if anyone slipped him a prawn.

ItsNotRocketScienceSteven · 23/05/2026 13:41

The theory that fewer intestinal worms is related to the rise in allergens is pretty strong. Plenty of research has shown this.

Intestinal worms release a chemical that dampens down the immune response (in order that they are not destroyed by the host).

Children began being treated for intestinal worms more regularly when the medication became readily available in the 60's, 70's, 80's and beyond. There is a correlation between a huge reduction in intestinal worms and the rise in allergic reactions to food stuffs.

Interesting. Parents in Australia and New Zealand used to routinely worm children, as we do dogs. They were shocked that we wait until there are signs of worms. I wonder if their rates of allergy are higher?

Whyhaveibeencutoutofmamsnot · 23/05/2026 14:25

We are too clean and used creams and cleansers on babies and young children which contained arachis oil from peanuts.
Mine were never fully bathed - top and tailed (I was too lazy and bathroom was cold) and my children have done the same with their babies and have no allergies yet.
