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).

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.

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.

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?

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.

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

LadyCrustybread · 24/02/2026 11:18

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.

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.

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’.

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.

Your interest in the source is then your own prerogative and access to the paper yours to organise if you want to get it. I can’t magic it out from behind a paywall.

You can't outrun your genes.
More and more discoveries are being made about how genes affect health outcomes.
We're all products of our parents and previous generations' genes.
There is now increasing evidence that parents' lifestyles and health pre-conception affects their children- fat people pass on 'fat gene DNA 'and ill health.

All we can do is maximise our chances of staving off chronic diseases and those related to lifestyle with our behaviour.

Edited

Yes you're so right. Unfortunately my 'pre-conception' conditions were very far from ideal - Mum didn't get enough to eat and was in an abusive relationship. It cannot have helped me. Still, can't dwell on that and have to just get on with things as they are.

I’m not particularly healthy but I do see a huge improvement when I eat better and drink water, my hair changed first, then skin, I get less stomach issues and move easier. Sadly one of the healthiest people I know died of cancer age 38 leaving behind two young kids, and she died quickly because she had so little body fat so no stores. She was so unlucky though, that’s how I think of it, she was a yoga teacher and sold foods at the local market so literally as healthy as they come and I think her dh is very caught up on the unfairness of that which is so sad and fair enough she was absolute light to everyone, so lovely

Icanthinkformyselfthanks · 22/02/2026 15:04

@StructuredChaos , note that Tim said ‘healthy years’ so he’s referring to health span not life span ie the number of years we live well and disease free. There are always going to be unlucky people who succumb to illness despite having eaten well and exercised and also those who frankly abuse themselves and live well to a grand old age. 🤷🏼‍♀️
The evidence supporting the impact of our diet and lifestyle on our chances of being ill or remaining well is so overwhelming now it’s pretty difficult to dismiss. It’s definitely not all about what we consume other factors are at play but I do strongly believe the more we try to incorporate the science that is currently understood the better we are likely to live for longer. You are correct however insofar as science evolves so more will be uncovered and some of what we think is true now may be debunked. Apart from keeping up with current scientific understanding I’m not sure what we can do about that really.

I really like this term "health span", and it's what motivates me to eat and exercise the way that I do (with the obvious caveat that obviously not all health conditions or illnesses can be avoided or controlled with a healthier lifestyle). As others have pointed out to the OP, it's not about extending your lifespan but increasing the number of healthy, active years you have within it.

As a nurse, I saw people whose bodies and minds were "elderly" at 60 years old, whilst others remained fit and active at 95. If there's an element to this that I can influence, then you're damn tooting I'm all over it!

NautilusLionfish · 24/02/2026 10:13

Womaninhouse17 · 24/02/2026 08:10

@NautilusLionfish 10 more healthy years doesn't mean adding 10 years to life expectancy. It means that you'd be healthy for 10 more years of your life instead of unhealthy with heart trouble or diabetes etc. So you'd be less likely to be a drag on the NHS rather than more.

Indeed. That is why am saying if UK healthy years expectancy is 62 but life expectancy is 79 then the focus (as we discuss this) should be that 62. If people who live 17 more years but not in greatest of health then better eating (and many other things) can give them more healthy years e.g. healthy life can improve to 72 rather than being 62. I put it crudely and honestly combined a part where I was being sarcastic and another where I was trying to bring facts in so you are completely correct in correcting me. even for me as a 48 year old, if I had lived a healthier life (more plants, more excercises, more meditaton, more socialising) I could have had healthier years at 48.

Ceramiq · 24/02/2026 10:13

Humans are mortal so obviously food choices can't prevent death. However, nutrition research is now very advanced and it is clear that much industrially processed food is exceedingly bad for human health and ought to be avoided. Whole foods from reasoned agriculture on the other hand have all sorts of positive health benefits which not only prolong life but prolong healthy life.

@LadyCrustybread don't worry - I understand what you and others are saying! I was just articulating my own struggle with hearing this message. I get that it is at a population level, but somehow my brain converts it into a more personal message and I have to remind myself that the cancer was not my fault!
