I’ve gone non UPF, I just can’t believe the difference it’s made in a week

I feel like such an idiot. I can’t believe how well I feel, how much I’m ready for bed and how much better I sleep.

this shit is radical. I was eating 40% upf (a teenagers diet is 80% 😱) and I feel brand new.

i have zero pain in my joints, during the day loads of good energy

does anyone else do this ?

I take it you read 'The' book? (Sorry, no time to RTFT).

It made me so mad and I made some immediate changes that I do think massively improved my health.

Dropping out the crap has majorly helped my auto immune condition (I'm now in remission). I have less head aches and my BP is down, as is my weight.

The things that really made the difference for me were replacing junk food/snacks with healthier alternatives, switching to sourdough and completely removing sweeteners from my diet, I think.

I have to admit, a year in and I DEFINITELY abuse my 20% some days. Life just gets in the way of cooking sometimes and other times I just need a packet of pickled onion Monster Munch to stay sane, so I have them.

Word of warning - be ready for UPF bread to become literally disgusting over time. Last week we stopped at McDonalds on the way back from Alton Towers water park and I was ravenous enough to order a burger. That fluffy, gummy, marshmallowy bun is so alien in your mouth after a while. It literally turned my stomach.

Also sweeteners, After literally 5 decades of drinking diet pop, I cannot even stand a sip of the stuff.

If you’re starting out, use the free food facts app to work out what is and isn’t UPF.

Got a Panasonic bread maker for Xmas. Genuinely takes about 2 or 3 mins to chuck the ingredients in and press go. Total game changer for us.

I dont eat bread any more (sort of) but got rid of my bread maker years ago because I couldnt manage the paddle in the middle of the bread, how do you get it out or slice around it?

WarriorN · 18/08/2025 12:02

I also agree you start to taste it when you do have it!

some supermarket breads are ok, there’s one we were already having by Sainsbury’s that is.

Holluschickie · 18/08/2025 11:53

People are confusing UPF and processed food. Rice or pasta or wheat or chicken are not UPF. They may be processed but that's ok. Rice or pasta or chicken in a readymeal or microwave rice with a ton of additives is UPF.

Regardless if you eat too much rice like I used to, it may lead to diabetes!

How do you know though? There’s a pasta at Sainsbury’s that just says pasta, tuna, tomato, cream. Like what you would put in a pasta dish at home. So what says upf there? So confusing

Just eating less bread. It’s like a drug withdrawal 😂 our sourdough starter lives in the fridge and gets used for a loaf at the weekend and occasional flatbreads in the week. Dried yeast in the UK tends to include emulsifiers.

Yes I gave up bread about 5 years ago before I discovered I have an actual problem with it and other similar things. I felt completely different. I still have some now and then, plus my cakes I make. Not ideal but very tasty.

Ive just put slices of it in the freezer so its out of sight and out of mind.

LaurieFairyCake · 18/08/2025 12:10

justsawjohnny - yep, not eaten upf bread in over a week. I’ve not missed it at all which I was surprised by.

I use Sainsbury's and cannot find this item that just has just tuna, pasta, tomato and cream. If its their tuna bake, there are at least a dozen other ingredients including preservatives, additives, emulsifiers etc.

Happy to be proved wrong if such a thing exists without preservatives etc.

igivein · 18/08/2025 12:15

There will be some form of acidity regulator in the tinned tomatoes. There has to be because tinned tomatoes can contain botulinum spores which are neutralised by a pH below 4.0. It's normal practice to check the pH and adjust to 4 to prevent botulism.
I used to work in a food science lab for a supermarket chain and this was one of the checks we had to make.
Edited to add - I'm not saying this makes them upf - it doesn't, I'm just saying that if the acidity regulator isn't citric acid it will be something similar.

Tuna bake, not a UPF

Honestly I did this for so many threads and most ready meals (fresh ones anyway) are not UPFs

Someone may already have suggested as not raft but Jason’s is UPF

Not always. Look up the NOVA system: world.openfoodfacts.org/cgi/search.pl?search_terms=jason&search_simple=1&action=process

Foods ranked 1, 2 or 3 are not UPF, 4 is UPF. Some Jason bread is 4 but others are a 3.

Yep, I just went and looked at Sainsbury's ready meals out of curiousity and the only ones I could find that had anything I'd consider a UPF were those that contained bacon/sausage. Anything chicken or tuna or veggie based only had 'normal' ingredients.

party4you · 18/08/2025 12:25

Kindly it’s only been a week so you’re really getting ahead of yourself. I find you obsession with telling us how little you eat a bit strange too.

Very interestingly on another thread where I spammed the thread with varying ready meals, it was Tesco from memory, someone was comparing with 'posh' ready meals because posters seemed to believe these were 'better for you' than bog standard Tesco basic stuff because it was 'cheap', Charlie Bingham being one of them, and waddya know, they are UPFs!!

The cheaper basic stuff I often find has less artificial about it. Not always but often.

Interestingly, according to that website, most cereals aren't UPF either, despite someone upthread saying they were. Crunchy Nut Cornflakes are apparently not, nor are Frosties...

soupyspoon · 18/08/2025 10:50

I know a lot about it

I havent eaten artificial sweetners for over 30 years. I was viewed as a bit of a quack about this, bit weird, a bit unnecessary. Even now people dont really see the issue with artificial sweetners, in my view its one of the biggest sources of harm in terms of how our bodies function and we are now paying the price

In terms of spiking, you can create dysfunction by overuse, of course you can. But to cite that as a reason not to eat a fruit smoothie, or some porridge is not where that overuse is coming from. The overuse and resistance comes from years and years of overeating, putting on excess weight, lack of balance and periods of rest inbetween overeating and eating consistently high levels of refined sugar/carb food stuffs.

Its not about a smoothie with a bit of honey, banana or some morning porridge

Or even, as someone earlier on the post threw up about pasta. Whole civilisations have managed to feed themselves, their descendents on white flour based products. Our health is compromised in modern times due to two main areas, over eating considerably and eating out of balance.

Thats pretty much it. Eat less, eat a wider diversity of foodstuffs and include lots of plant matter. (bit like my bloody chickpea salad which I hope to see the end of sometime this week)

The history of white flour use is interesting as its extraction was such a labour intensive process that it was reserved for the wealthy. As a result there is evidence of more tooth decay in the upper classes than in the peasants, more digestive complaints (due to lower fibre diets) and greater incidence of gout and obesity than among the peasants.

It wasn't until milling in the 19th century when white flour use became more widespread that beriberi (thiamine deficiency) and pellagra (niacin deficiency) become common amongst the masses. The recent fortification of flour is a reflection of the need to replace the nutrients which have been removed.

Well this is why I wouldnt use an app or a rating score. If its got the general ingredients in it that I would use in my kitchen to make it, then its normal food.

And also why demonising something as a UPF as if thats the be all and end all of 'healthy' is a nonsense.

Look at my fudge, which I am unfortunately looking at. Even though I dont really believe in 'healthy' or 'not healthy' foods, no one in their right mind would say it serves any nutritional benefit really. Its got tahini, salt, sesame oil, condensed milk. Some nutrition from the seeds I might argue, but nothing else

But you know, its not a UPF and I cooked it from scratch!!

This thread is a living proof that critical thinking needs to be applied to any book. This is my lunch today - it contains several UPFs, mainly thickeners in Korean sweet potato noodles and in tofu. I’d rather have this vile thing than a bag of clean good UPF-free crisps 🤷‍♀️

LaurieFairyCake · 18/08/2025 12:37

party4you someone asked how much I eat. I can only eat 1000 calories as I’m very short so I responded. It’s important that people who can eat more as they’re taller or have different needs scale up. I literally said this is what I eat and detailed everything I ate, it’s not other people’s calorie needs.

No crisps can be UPF free.

The clue is in the name- crisps.

Unless you're making your own kale crisps in the oven.

Maybe you need to do some critical thinking?

You need to RTFT :-), there’s a whole section about UPF free crisps.
