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 think there is definitely something about "foreign" foods.

My great grandmother could have been allergic to kiwis or soy or brazil nuts, but she died in 1954 and such exotic foods wouldn't have reached her rural village.

There is much more to be allergic to now. Food in itself has become more complicated too, coming from all over the world and being (ultra)processed into other food items.

Exactly

also more vegetarian/vegan foods contain nuts. I love it so feel very lucky
Im not allergic!

Newsenmum · 23/05/2026 20:25

I agree with the poster who said nuts are now in a lot more foods

Newsenmum · 23/05/2026 20:24

They were pretty common in my childhood in the 90s. I remember a girl dying from one round the corner. We also just care more about not killing those people now!

There's a lot of evidence that exposure to the outdoors, particularly mud, reduces the likelihood of allergies and autoimmune conditions.

For example, studies comparing schools with natural playgrounds vs artificial surfaces have found far less incidence of a whole range of childhood illnesses. Something to do with early exposure to a wide range of immune boosting stuff.

It’s because doctors prescribe antibiotics to tiny babies all the bloody time before their guts are established (sometimes before they are even born when their mothers are pregnant or in labour for “preventative reasons”). This eradicates the gut bacteria and it all grows back wonky as there hasn't been enough time for a healthy foundation to have developed. The damaged gut leads to eczema, which in turn leads to food allergies developing.

My daughter has a lot of allergies unfortunately because she was given preventative antibiotics as soon as she was born.

It’s not just food allergies that are common - also IBS, IBD, bowel cancer, autoimmune diseases - all different expressions of our country’s poor gut health.

I had a completely different experience, my GP has done everything to not prescribe antibiotics to my daughter, it's a last resort. Same experience as my mum friends.

Actually, same as me over the last couple of years, our GP is very reluctant to prescribe antibiotics unless absolutely necessary.

My LO had antibiotics at birth as she had a serious infection, thankfully she's as healthy as a horse.

A few good points raised here, but also, like autism and ADHD, it's probably an awareness thing as well.

DustyMaiden · 23/05/2026 19:54

After 12 miscarriages and 1 still birth I was advised not t eat nuts in my next pregnancy. I gave birth to my lovely DS who has a nut allergy.

GentleSheep · 23/05/2026 19:52

I grew up in the 60s and recall having packets of salted peanuts occasionally. I don't recall anyone with allergies - although I developed a bad grass pollen allergy at age 15. I don't think it has anything to do with vaccines, I think it's a dietary issue, that diets are more deficient now than back then.

CuteOrangeElephant · 23/05/2026 19:44

I have read that c-sections are associated with higher food allergy rates.

My baby DD has been referred to a specialist for potential egg and dairy allergies and she was born by c-section. Cue major mum guilt of course despite not really having had a choice.

I also grew up in the 60s and 70s and, quite honestly, you just never heard of food allergies. Even as a younger adult it wasn't something that was common.

I have read similar to a PP that exposure from an earlier age can reduce allergies. I think the main reason people used to avoid giving young children nuts was the choking risk rather than allergies.

I remember a lot of kids at primary being allergict, with the t, to strawberries.

I do wonder if it's because ( historically) most of the allergens are " foreign ".
We don't live in a country where peanuts and peppers have always grown and been eaten. Even in the US, most people haven't been there beyond a few hundred years.
My theory is loosely based in the fact that I grew up in rural Kent, definitely exposed to fruit trees, grasses and hay, but didnt develop awful hay fever until I moved to Cornwall as an adult and was suddenly exposed to foreign pollens. Damn you, white flowering trees! 🙄

There was a really interesting Zoe podcast recently with a doctor who specialises in allergies. He said that research suggests babies get nut allergies by being exposed to nuts through their skin before eating them. The immune system doesn’t recognise them as food. It’s more likely to happen if a baby has eczema and so the skin isn’t an efficient barrier. Also more likely with sticky products such as peanut butter. In cultures where humous is eaten more then sesame allergy is more prevalent than nut allergy.
I haven’t heard it all yet so not totally sure how this explains the rise in allergies. More peanut butter? More eczema?

That's interesting @Pandorea . I was pregnant in 2001 and ate lots of 'nutritious wholemeal rolls with peanut butter ' as that was the advice in my pregnancy guide at the time (as long as no food allergies in the family). I presume I passed it on to DS through breast milk. But I remember reading at the time that there was no incidence of nut allergy in North Africa and I couldn't see why that would be when nuts are prevalent in their cuisine.

I knew a young person with walnut allergy born in 1966 or 1965, It wasn't unheard of.

Ace42 · 23/05/2026 19:13

I didn't restrict any kinds of foods when I was pregnant. Neither me nor my eldest son's father have any food allergies yet my eldest son had CMPA from word go, asthma and severe eczema. He was exclusively breastfed until 5.5 months and even reacted to what I ate through the milk and had a very severe anaphylactic reaction to peanut butter on a rice cake when he was just 9 months old. He now has to carry two epi-pens everywhere he goes. I wish I knew why these allergies are increasing in children but I think it must be multifactorial. My youngest child is allergic to nothing at all and is in perfect health.

Yes they worried about the whooping cough vaccine and doctor delayed one of my kids having it in the 70s. He got whooping cough which was awful.

I wasn’t allowed the whooping cough vaccine as my sister reacted badly to it. I’d not heard it was a whole allergy thing, super interesting.

I have a nut allergy, had it since the 70s and I wasn’t the only kid in my class with an allergy.

dizzydizzydizzy · 23/05/2026 18:41

I don’t think anyone knows for sure why people are more allergic now. I have heard numerous theories.

One thing I do know is that allergies can come and go. Also DC2 was misdiagnosed with peanut allergy in about 2007. Apparently, someone discovered that when doing skin prick tests, the body cannot always tell the difference between grass pollen and peanut, so many people get a positive reaction to peanut if they are allergic to grass pollen. Anyway, in about 2015, DC2 had a blood test to confirm the misdiagnosis.

There was an egg based vaccine some years ago that you couldn't have if you had allergies but I am sure that was changed. Never heard of a peanut one.

I’m 59. I have a tea nut alert diagnosed when I was 7. When I was at school no one believed me. So UABU.

TheignT · 23/05/2026 18:25

I don't know anyone with a nut allergy. My kids, their partners, eight GC, nieces and nephews and their kids.

My husband is allergic to penicillin, does that count.

Epi-pens only became in common usage in the uk between the 90s and 00s. Before then peoples survival rate was lower from being exposed. There is definitely survival bias going on.

There is some argument that lack of exposure at all as a baby or during pregnancy can cause it as well.

Allergies are so strange. I used to get the worst hay fever ever, now I don't get any at all. After my first pregnancy I developed a tree nut allergy, confirmed after serious reactions and then allergy tests at hospital. Last week I made a mistake and didn't read some packaging properly and accidentally ate hazelnut. I had no reaction at all. So it seems I'm no longer allergic to hazelnut. The only difference between then and now is I've gone through menopause. For me I think major hormonal shifts have affected my allergies.

It like asthma. Some people only have it in childhood. Others have it for life.

When I was young (primary school) I remember being told more than once that children before the age of 3 shouldn’t eat nuts because their throats were too small and they could choke on them. Looking back on it I suppose some young children with nut allergies died and it was perceived as choking.

The oil can also cause pneumonia if inhaled during choking as well.

ShetlandishMum · 23/05/2026 07:28

No it isn't.
Standard childhood and adult vaccines are generally safe for those with peanut allergies as routine immunizations.
There is no credible scientific link between vaccine ingredients and the development of food allergies such as a peanut allergy.
