To think there's a growing amount of people who think food can fix everything?

Was listening to some ZOE podcasts, and love eating healthy foods myself, so it isn't a criticism of nutrition awareness. I'm a bit of a cooking nerd so love all of this stuff and finding new recipes, but I am noticing more and more people who seem to believe that eating low upf and fresh fruit and veg can add 'decades' to a human lifespan.

It certainly won't shorten it!
Surely this is an oversimplification, though?

I have always eaten in a kind of 'ZOE' way, and whilst I don't have any metabolic disease, weight problems or other issues, I am not so confident that I am going to outlive my peers due to this. It's something I can control, yes, and that's great, but I think it's deceptive to think we won't ever get cancer, heart disease, dementia or auto immune diseases if we eat in a 'clean' or ideal way.

Not to mention the 'ideal' keeps bloody changing!

I don't think life is that simple at all, even though I do champion healthy, fresh diets.
I see people who claim their spots, headaches, IBS, brain fog, joint aches and other issues immediately cease when they start eating fresh fruit and veg, or low histamine, or low inflammatory diets...... What puzzles me, as someone who has always enjoyed high fibre and fresh foods, is how nebulous those symptoms are, and not very well understood by GP's.
It allows for all manner of snake oil claims online, since the placebo effect is strong.

Just saw a vid with Tim Spector claiming that eating the ZOE way will certainly add 10 extra healthy years to your life. So if we use myself as an example of this, it doesn't take into account my familial heart disease, stroke risk, potential genetic cancers, and a world of non food related risks, of which there are countless examples.

It reminds me of those people who think they will never get ill because they don't smoke. Neither did my parents, but they died before their time (sepsis and vascular dementia).

Epidemiological studies showing a protective effect of diets rich in fruits and vegetables against cancer have stressed on the possibility that naturally occurring phytochemicals can exert anti-carcinogenic activity. Evidence is also accumulating to support the notion that provision of a combination of dietary bioactive agents is more effective than treatment with a single dietary component. Thus, it is reasonable to assume that combinations of components could be designed to either target multiple pathways or exhibit potentiation or synergy of specific pathways. The interaction of components of the diet clearly requires more focus and further research.

@LadyCrustybread it's work in progress.

Not disagreeing but it's not conclusive from this link.
Which is outdated- more recent stuff is available.

Thanks. Happy to read the newer research. I also don’t think I’ve seen anyone actually post anything arguing that a healthy diet absolutely doesn’t contribute to the systems behind apoptosis and therefore I stand by my point until proven / sourced with a reasonable oppositional argument.

So far nobody seems to actually disagree with me they just seem to want to pick apart my source.

LadyCrustybread · 24/02/2026 11:22

Here’s a 2023 source that states - ‘Reviewing the literature, almost all articles concluded that the transition to one of these diets (health-conscious diets of the Mediterranean, ketogenic, and plant-based diets) was beneficial in preventing cancer incidence or reducing progression (transition to metastases), tumor staging, tumor markers, and inflammatory markers’.

This journal isn't the most reputable in the field. Its peer review process is a little questionable.

There is so much research on this whole topic. Diet is everything. Lowers cancer risk, lowers heart disease incidence, even lowers dementia /Alzheimer’s. Healthy diet as a bedrock for healthy living is a foundation for longevity. Clearly stress levels and emotional well-being play a part too, but managing your diet is the thing most in your control

So not everything then.

I’m certainly not arguing with you. I would be interested to read the research you’re referring to in your posts. But you’ve said you don’t really have any, so I would take that up mean you’re pretty confident that plant food can kill cancer cells but you don’t know how to demonstrate that confidence, which is fine.

but it feeds into the Zoe argument- and really it’s on the same axis as conspriacy theories- it sounds right, it can’t do any harm to follow it right?

The issue is when people who are not emotionally healthy (ie have eating disorders) use these ideas in an unhealthy way- puritanically, the preach, to reinforce their delusions. And that’s what the thread is about.

maskymask · 22/02/2026 21:04

I’m sure recent research said genes are more responsible than originally thought for longevity.

Yeah but longevity isn't the same as 'health span'

I agree OP - having Psoriasis has meant lots of people have lots of views, including about diet. It's exhausting and guilt inducing.

I gree about thinking that rather than increasing lifespan or healthspan with good diet we need to think of shit food reducing the optimum

TwoLeftSocksWithHoles · 24/02/2026 11:49

Food certainly can't "fix everything". I was trying to put up a curtain pole and it kept falling down - the butter just wouldn't hold it.

I had another problem with the sausage draft excluder I had made. My friends dog wouldn't leave it alone.

You’re misquoting me and that is unfair. I have never said that plant food kills cancer.

I said that the food we eat contributes to the systems behind apoptosis (programmed cell death that takes out cancerous cells in the body). Aka the systems that destroy some cancer in the body.

You are misrepresenting my argument, I have shared multiple peer-reviewed journal sources that argue that healthy diet plays a part in apoptosis. How that is conspiracy theories or not really having any research I don’t know. Do you want me to conduct the studies myself?

TBH, a great deal of published diet research is here today, gone tomorrow. It’s not a very well-regarded field. Or at least, any real world recommendations supposedly drawn from the research are treated with a great deal of scepticism. In any case, it’s nearly always faddists who come up with diet-related health stats and conclusions, not the authors themselves.

That's not really true.
The papers I have read are from scientific research across the world . There are stats showing a far better response to immunotherapy in patients with healthy guts compared to patients without.

I understand that ideas change- once upon a time fat was the demon but now it's sugar and UPFs.

This is more to do with advances in medicine and research.

TheNinkyNonkyIsATardis · 24/02/2026 13:00

When I was experiencing a period of high stress, I got put on a coaching programme they were trialling with the NHS.

They went into a lot of the science around stress and diet. Your body will "store" stress in fat, in a way to cope with it (this made a lot of sense as I piled on lbs even though I was hardly eating). Your body also treats UPF and other intoxicants in the same way it rests stress.

Your gut is designed to handle bad nutrition to a certain extent - but low fibre and nutrients and high UPF can damage the gut's ability to do this, causing Leaky Gut syndrome, so that the elements that were filtered out return to the bloodstream. A negative cycle.

Oh, and when you lose weight, the stressors held within it are let out again!

There's also a second "UPF" - Ultra Palatable Food. Moreish food that has been perfectly calibrated to keep you reaching for another without giving you any nutrients.

I'm not looking to live forever, but recalibrating yourself away from this stuff is a no brainer IMO.

NautilusLionfish · 23/02/2026 21:08

This is true. But its also dangerous to peddle that with healthy food all will be well. UK life expectancy is 83 years for women and 79 for men. So Spector giving us 10 more year means women die at 93 and men at 89. We need to have all the other pieces of the puzzle in place to support that. What is more interesting is that UK's healthy life expectancy is much lower, 62 for both women and men. So this is what needs to change and again it will take more than food (including social networks and support). Another discussion that things like Zoe podcasts dismiss is how costly the healthy foods to get you that extra 10 years are for most family (my kids love fennel and cavolo nero. Fennel is £5 a bulb at the local sains. And that not even organic! CN is also expensive but at least we can afford that regularly). To an extremish example and Zoe specifically, the gut health bundle would cost an individual about £33 a month when you subscribe i.e. 133 down from 180 (Excluding other things we "need" like kefir, good quality dark chocolate, etc). So a family of 4 need to add £132 to their monthly bill (but don't despair. That's 4 fancy measuring spoons with it!). To be fair you can make it yourself probably for cheaper.
And then there is the fact that good food is generally home made, knowledgeably made food. Unless you can afford a personal chef or something, this burden will largely fall on the already exhausted, burnt out women of his majesty's United Kingdom of Great Britain and Northern Ireland (Thanks Sir Humphrey Appleby!). Increasingly, at least in our area, I see adverts of professionals seeking a second part time "job" to patch up finances so who has the time or energy to buy and make fresh foods and sprinkle seeds and berries on it, then exercise, meditate, drink 17 cups of green tea or whatever latest herbal tea from the amazon? Apologies @Ghostspritz am putting so many posts into one not just replying to you.
@StructuredChaos take the wisdom and leave the additives. I do think there are great things that people like Spector have done, like increasing awareness of gut health and the importance of fibre. But as it typical in our world there is a part that has been kidnapped by the capitalist monster and starts peddling fluff. Do what you can!

Hear hear, and hear hear again. Spector's variety of healthy eating is out of reach for such a huge proportion of households and it isn't just about money, to anyone pointing out that cooking from scratch is cheaper than KFC or whatever.

Unfortunately I cannot help with that. I’m not the person in charge of access to scientific journals. Maybe you can find it elsewhere with the following information.

The title is: Apoptosis by dietary factors: the suicide solution for delaying cancer growth

Main author: Khan, 2007.

Academic papers are often trapped behind a paywall and generally only academic institutions have access so only academics like me or students can read them.

It was also scientific evidence that stated fish is great for you, and then bad for you. Ditto meat, butter, eggs etc. Science evolves. I have no doubt UPFs are shit for you but the polluted air in the UK is too.

Perhaps it will make more sense to you if you think of it as eating crap (high fat, high salt, low nutritional value foods, UPF etc) that can cause health issues can shorten your lifespan rather than eating well can lengthen it.

Both the same thing really, they just assume different starting points.

This. Its not that it can cure everything OP but I don't think you realise how badly most people eat and yes for them these changes are life changing and will resolve smaller issues like spots and energy that they had issues with.

Do you realise how badly “most people eat” though? How?

Bluedenimdoglover · 24/02/2026 16:06

Just don't eat crap and highly processed food. No-one should deny themselves a treat on occasions, but just a treat. Life's too short to worry yourself unnecessarily about how long you'll live. A lot is down to your genes.

That’s not really true though is it? Chances are good that if you stop smoking, or drug taking, or heavy drinking the last 40 years of your life that you could have a longer halathy life. Bad diet to good diet is very less certain.

I'm not sure this is any more fact based than what I said.

I 💯 agree! The gym bunnies and their protein obsession- I don’t know how they even shit! And yet they harp on about it constantly, especially when they take to social media.

An orthorexic/ protein obsessed friend said to me just yesterday “I eat loads of fibre! For example for breakfast I had poached egg and spinach” 🤣 healthy? Yes. It has next to no fibre though.

however, life is life and the aim of all people to be eating an optimal diet rather than choosing what they like is bizarre.
I have plenty of friends who eat brilliantly and gym but then once a week go out to an amazing restaurant and drink strong 5 cocktails. Why not?

a couple of them were obese by the way, part of your 30%. They’re actually not obese anymore as they’re on weight loss injections. Nothing else has changed in their lives but I imagine the orthorexics excuse them from
the disgust now their BMi is under 30.

No @Itsmetheflamingo, they will probably start banging on about how using WLI is cheating and people just need to eat less and move more ! They still need to find a way to feel superior.

I was thinking this. So maybe it's more 'starting to give a crap about your health in some way makes you more healthy'.

Crikeyalmighty · 24/02/2026 17:12

Pretty sure people like Chris Hoy etc had a pretty healthy diet and a lot of excercise - I certainly think not having a healthy diet is more likely to bring on certain ailments but eating healthily isn’t a total panacea -

Sounds like it's open season on 'gym bunnies' or those you've diagnosed with orthorexia, but WLI shaming is absolutely not ok?
