Thousands of UK deaths could be linked to ultra-processed foods

Ultra-processed foods have been linked with tens of thousands of early deaths in the UK in a new study.
If you're anything like the typical Brit, you may well be eating dozens of these foods today alone.
They could include cereal and flavoured yoghurt for breakfast (even cornflakes are often UPF), sliced bread with cream cheese or ham for lunch, a ready meal for dinner, and some biscuits or crisps as a snack.
But these foods could be harming our health in ways that are still not fully understood, the study published in the American Journal of Preventive Medicine says.
They looked at data from eight countries around the world and found UPFs made up 53% of people's energy intake in the UK – the second highest in the study after 55% in the US.
The researchers suggested that in 2018/19, some 17,781 premature deaths in the UK could have been linked to UPFs, according to their model.
Premature deaths attributable to UPFs ranged from 4% of premature deaths in lower consumption settings, such as Colombia, up to 14% of premature deaths in the UK and US, according to their mathematical modelling.
Authors called on governments to issue dietary recommendations aimed at cutting consumption of UPFs.
A Department of Health and Social Care spokesperson told Metro: 'This government is committed to tackling poor diets and the obesity crisis to protect future generations.
'We have already taken action to end the targeting of junk food adverts to children, across TV and online and we have handed local authorities stronger powers to block applications for new takeaways near schools.
'We are also commissioning research to improve the evidence on the health impacts of ultra processed foods. Through our Plan for Change, we will shift the focus from sickness to prevention, reducing the burden of obesity on public services and the NHS.'
In recent years, ultraprocessed foods, or UPFs, have been a growing concern, with Facebook groups springing up full of people trying to cut down, and brands such as M&S and Crosta Mollica responding with products free of the additives and emulsifiers that typify industrially produced foods.
It follows the smash hit success of the book Ultra-Processed People by Chris van Tulleken, who went as far as to say many of these new processed substances are not even really 'food' at all.
An exact definition has been hard to pin down, but one popular one is that they include ingredients you wouldn't typically find in a home kitchen, such as E-numbers, emulsifiers, thickeners, and colourings: potentially things like potassium sorbate, soy lecithin, mono and diglycerides, guar gum and aspartame.
Here is a list of common ultra-processed foods to be aware of: Sweetened breakfast cereals
Instant soups
Pre-packaged and microwave-ready meals
Fruit-flavoured yoghurts
Spreads
Reconstituted meat – e.g. ham, burgers, chicken nuggets and sausages
Ice cream
Crisps
Biscuits
Soft drinks and some alcoholic drinks – including whisky, gin, and rum
But it's not just things thought of as 'junk foods': even things like baked beans, coconut milk, low fat spread, fruit snacks and vegan burgers can be ultra-processed.
The Nova classification system sought to break it down, splitting foods into unprocessed, minimally processed, processed and ultraprocessed.
The further something gets from its original ingredients, the more processed it is.
We still don't know for sure.
UPFs have been linked previously to poor health, including to an increased risk of obesity, heart disease, cancer and early death.
It could just be that they are often high in saturated fat, salt, and sugar,so eating them means we have less room in our diets for more nutritious foods.
But it could be because they tend to include additives and ingredients that are unhealthy, such as preservatives, emulsifiers and artificial colours and flavours.
Some emulsifiers, for example, used to bind foods together, have been accused of disrupting the gut biome and causing inflammation.
Lead investigator Eduardo Nilson, from the scientific body the Oswaldo Cruz Foundation in Brazil, said: 'UPFs affect health beyond the individual impact of high content of critical nutrients (sodium, trans fats, and sugar) because of the changes in the foods during industrial processing and the use of artificial ingredients, including colourants, artificial flavours and sweeteners, emulsifiers, and many other additives and processing aids, so assessing deaths from all causes associated with UPF consumption allows an overall estimate of the effect of industrial food processing on health.'
Dr Nilson said the study found 'each 10% increase in the participation of UPFs in the diet increases the risk of death from all causes by 3%'.
Probably not the companies who make UPFs, but aside from them, scientists caution that it is too early to rush to conclusions about the dangers of UPFs.
Nerys Astbury, associate professor from the University of Oxford, said it is known that consuming diets higher in calories, fat and sugar can have detrimental effects on health, including premature mortality.
She said: 'Many UPF tend to be high in these nutrients, and studies to date have been unable to determine with certainty whether the effects of UPF are independent of the already established effects of diets high in foods which are energy dense and contain large amounts of fat and sugar.
'The authors of the study conclude that advice to reduce UPF consumption should be included in national dietary guideline recommendations and in public policies. More Trending
'However, rushing to add recommendations on UPF to these recommendations is not warranted based on this study in my opinion.'
She said the Nova system, which defines foods according to different levels of food processing, 'has many limitations, including arbitrary definitions and overly broad food categories' and added: 'More research is needed to ascertain a causal link between UPF and disease and to establish the mechanisms involved.'
You'd have to balance the health benefits with the joy of a little indulgence.
If you really want to be on the safe side, a boiled egg and an apple would probably be better for you.

I took Mounjaro and the results changed my life

I took Mounjaro and the results changed my life Jess always struggled to manage her weight, however a year after using the controversial Mounjaro vaccine, she has now lost 100 pounds Jessica shared the moment where she was able to travel abroad - without using a belt extender (Image: Jessica Miles ) For Jess Miles, a 37-year-old secretary from Newcastle Emlyn, weight had always been a shadow in her life. It was a battle that stretched back from her childhood and stubbornly into adulthood. "I've been overweight since I was a kid. It got worse after I had my son, nearly 16 years ago," she says. "I've tried everything - Slimming World, Weight Watchers - you name it! I'd lose a couple of stone, then binge eat, put it all back on and give up until the next time." ‌ However, the wake up call came with two gut wrenching moments: stepping on the scale and seeing 24 stone and four pounds, and the whisper of her late mother's final wish. ‌ "I lost my mum just before COVID," Jess shared. "One of the last things she ever said to me was that she wanted me to lose weight. She was a big woman too, but after getting diagnosed with diabetes, she changed everything. She went from a size 26 to a 14 - it was really amazing to see. She did it - and she wanted the same thing for me." This echoed through Jess' mind when she looked at herself last year. "Reaching 24 stone.... I cried. Honestly, I felt ashamed of myself. I thought that if I don't do something, I won't live to see my son turn 18." A year ago, Jessica weighed 24 stone and four pounds (Image: Jessica Miles ) Article continues below That's when she found Mounjaro - a weight loss option that has become increasingly familiar in the public eye - for both positive and negative reasons. Jess had started seeing the name crop up on Facebook and TikTok, the latest buzz in weight loss. "It was everywhere," she recalled. "But I didn't know anyone who had tried it. Back then it was so new, so I was very apprehensive about it." It wasn't just the unknown that made her hesitate. It was the cost - upwards of £250 a month. "I kept putting it off, thinking 'I can't afford this'. But one day I just thought, b****r it! Something has to change and nothing else has worked!" ‌ Armed with this sudden burst of determination, she booked a consultation with Iechyd Teifi Health, a private clinic. On July 4, 2024, she walked in, shaking hands with the consultant with a pounding heart: "I actually said out loud, 'I don't know what I'm doing here.' I was so incredibly nervous." Jess was honest from the start about her biggest worry: the side effects. "The list was terrifying," she admits. "I have read that there are possible cases of thyroid cancer, liver and kidney issues.... not to mention the more common stuff like nausea or constipation." These concerns weren't unfounded. The NHS website notes, "Common side effects, include: ‌ Feeling sick Indigestion Constipation Diarrhoea "There can be some more serious side effects, such as low blood sugar, gallstones and inflammation of the pancreas (pancreatitis)." Fortunately, Jess had no underlying health conditions that would have put her at severe risk with the treatment. Through further discussion with the doctors at her workplace, Jess was given the green light to proceed - with agreement to have regular blood tests to keep everything in check. ‌ From the moment she took her first injection, almost a year ago, Jess says something shifted. "I had my first injection the day of my consultation. That night, I remember sitting down to eat and I just... couldn't," she said. "There was a full plate of food in front of me, and I managed about a quarter of it. I physically couldn't eat more. It was shocking. Normally I'd eat massive portions without a second thought." That initial shock was quickly followed by nausea, a side effect that lingered for the first few weeks and continues to take hold. "I wasn't used to it in the beginning. I felt sick a lot, especially the first weekend. I barely ate anything," Jess says. "But weirdly, I sort of needed that reset. It forced me to stop and think about what I was putting in my body." ‌ That thought struck after a late night stop at her local chippy. "I had a portion of chips and my gosh was I ill that night. It must have been all the grease and fat... From that point on, I realised I had to actually change what I eat." Jess didn't give up all her favourite foods - she didn't need to. But her relationship with them has changed. "Chocolate used to be my downfall. I used to be able to eat a whole bar of Galaxy in one sitting. Now? A square or two and I am genuinely satisfied." Jessica shared that she had always struggled with her weight but since taking the injection has seen an incredible difference (Image: Jessica Miles ) ‌ Her drastic change in appetite has also impacted her daily routine. "I don't eat breakfast now. A coffee keeps me going until about half ten and then I'll have a small portion of fruit before lunch. If I have a proper lunch, sometimes I don't have supper. I have cut down on all my snacking. The injection has changed everything." And yet in those early months, people didn't believe it would last. "I think a lot of my family and friends thought I'd give up like I always had before, and I don't blame them! I had a history of starting strong and then slipping back into old habits. "But this time was different. They started to take notice when I hit that two-stone mark. That's when they realised I was serious." Stay informed on the latest health news by signing up to our newsletter here ‌ Jess' biggest cheerleader wasn't around to see it, but Jess knows that her mother is with her in spirit. "Honestly, she remains my biggest motivator, through all the tough moments. I know my mother is looking down on me and is proud of what I have achieved!" Week by week, stone by stone, the weight has come off. "I weigh myself every morning before work. I go in and tell the girls, 'I lost three pounds!' and they're just as excited as I am. Everyone has just been so amazing and supportive." For Jess, her biggest milestone came during a shopping trip. "I didn't really want to go clothes shopping because of how much my weight was fluctuating, but it got to the point where I was looking stupid going to work because of how oversized my normal clothes were. ‌ "I remember on that trip, picking up a t-shirt in New Look in my usual size 24, without thinking - it drowned me. So I grabbed a size 18 - still too big. I ended up buying a size 16. I hadn't been that size since school." She stood in front of the store, holding the old size against her body - gobsmacked. "I nearly cried. It wasn't about the clothes. It was seeing for the first time how far I come. No matter how much I look in the mirror, I can't register the changes, but in that moment it became undeniable." Now 49 weeks in, Jess has lost seven stone and two pounds - exactly 100 pounds. ‌ Jessica said that her friends and family can't get over the difference Mounjaro has made (Image: Jessica Miles ) "I still can't believe it," she says. "That weight is basically equal to a size of a small child.... it's crazy! It blows my mind." Beyond the physical changes, there has also been a change in mindset. "A small part of me used to dread weekends. I've got a little balloon business on the side, and I'd find myself sweating, exhausted putting party displays up. But I now find myself with this new lease of energy that makes me get up and want to do it." ‌ That renewed energy carried through to every part of her life - even travelling, something that once brought discomfort and embarrassment. "We went to Mallorca last year and to get on that plane and not need a belt extender? Oh my god, that was the best day of my life!" Those kind of moments - picking up a smaller size, getting through the weekend without feeling breathless, not using a belt extender - have defined Jess' year. She is now a comfortable size 18, with aspirations of reaching a size 16. "I'd say lose another two stone and I am happy. I am now preparing for my final injection - I will be stopping after this month. With the £250 a month I have been spending, I plan on putting it towards going to the gym and swimming to tone up! ‌ "I am so proud. I have honestly never been happier and that's really why I am sharing my story. I have seen so much bad conversation surround this injection and people who are on it are too embarrassed to even talk about it - but I am living proof of it working. "If you have no underlying health conditions - and I say this in big, bold, capital letters - then I would 100% advise anyone to take it. The impact it has had on me has been out of this world." There is a slight sting that this injection may become readily available over the counter after a short consultation - at the cost of an NHS prescription. The possibility was difficult pill for Jess to swallow, she confessed. ‌ "I was heartbroken," she says frankly. "One of the girls in work told me and I was swearing, ranting and raving. People are going to be able to walk into a doctors and get it for free when I've spent thousands. "That did hit me quite hard." Still, she understands the benefits of wider access - especially when done safely and with the right medical support. "I know it's safer through the NHS, because they have your full medical history. That's what really matters - making sure it's done properly." ‌ And for Jess, peace of mind was worth every penny. "I know I could've gotten it cheaper online, but I didn't trust it. I wanted to be supported and monitored. I felt safe doing through the clinic and I don't regret that." As Jess prepares to step into the next phase of her journey - one without Mounjaro, but with motivation - she hopes her story helps others feel less alone. She's already had dozens of people reach out through her social media. "Some people message me saying I've inspired them to try it. Others are asking about the side effects. I always say the same - for me it was mainly constipation and some nausea at the start. But nothing major. The nausea only hits if you overeat, because your body just can't handle it anymore." Article continues below Her routine is different now, more mindful. Smaller meals. Higher protein. Regular movement - even if it's just walking the dogs or getting her steps in during her lunch break. Yet her message is clear: "Be honest. Don't take it if you have underlying conditions. It's not a shortcut, it's hard work - but it does work."

Map reveals UK areas with highest rates of erectile dysfunction

Sometimes, no matter how hard you try in the bedroom, the erection just doesn't want to happen. It's sometimes considered a relatively taboo subject, but erectile dysfunction is actually much more common than you might think – and it doesn't need to dim your shine. More than half of men have admitted to experiencing it (58.2%), while just over a quarter (27.3%) say it's cropped up during more than half of their sexual encounters. Hey, no stigma. Now, new research has revealed the top prescription hotspots for erectile dysfunction – and it shows that men in the East Riding of Yorkshire are coming out on top. Here, 3.5% of the local population are taking sildenafil on the NHS (also known under the brand names Viagra, Aronix, Liberize and Nipatra). Northumberland came in second place at 3.3%, while Dorset was ever so slightly behind at 3.2%. Up in Lancashire, Fylde and Wyre residents rank at 3.2%, as do the people of North Yorkshire. 'NHS provision of this treatment can vary from region to region, as can the ratio of underlying disease, which probably explains some of the differences,' consultant urologist Gordon Muir, of London Bridge Hospital, told The Sun of the NHS data. Sildenafil was first discovered by scientists at Pfizer in 1989, who at the time were working to create a treatment for angina (tightness in the chest). After various clinical trials, it was patented in 1996 and approved for use in both the UK and the US in 1998. Love reading juicy stories like this? Need some tips for how to spice things up in the bedroom? Sign up to The Hook-Up and we'll slide into your inbox every week with all the latest sex and dating stories from Metro. We can't wait for you to join us! These days, sildenafil is prescribed for those experiencing either erectile dysfunction or pulmonary hypertension (high blood pressure in the blood vessels that supply the lungs), both by the NHS and private medical providers. However, Viagra mostly isn't available on the NHS, though exceptions are sometimes made for 'special circumstances.' It's worth noting that sildenafil isn't just available on prescription, as it's also possible to pay for it at the pharmacy. You'll need to discuss your symptoms with them, and they'll then assess whether it's safe for you to take it. Thinking about alternative ways to make your erection stronger? As Dr Jeff Foster, men's health specialist and advisor to proven ED topical gel Eroxon, previously told Metro, the little blue pill isn't the only option: a few simple lifestyle swaps might be just the ticket. Regular exercise can also help, particularly workouts to strengthen the pelvic floor and prevent erectile dysfunction, which strengthen the muscles needed to get hard. Likewise, the more aerobic exercises you do – any form of physical activity that increases your heart rate and how much oxygen your body uses, like running, brisk walking or swimming – the more blood flow to your penis, and the harder the erection. Have ever had an allergic reaction to sildenafil or any other medicine Are taking medicines called nitrates for chest pain (angina) Have a serious heart or liver problem Have recently had a stroke, heart attack or a heart problem – your doctor should carefully check whether your heart can take the additional strain of having sex Have low blood pressure (hypotension) Have a rare inherited eye disease, such as retinitis pigmentosa Have sickle cell anaemia (an abnormality of red blood cells), leukaemia (cancer of blood cells) or multiple myeloma (cancer of bone marrow) Have a deformity of your penis or Peyronie's disease (curved penis) Have a stomach ulcer Have a bleeding problem like haemophilia. Improving your diet can similarly go a long way. In 2018, a study published in Andrology concluded that men aged between 18 and 40 who consumed dietary flavones (a compound in food found in fruits, vegetables, tea and coffee) experienced a positive impact on improving erectile dysfunction and soft erections. More Trending Not resting enough? Poor sleep can similarly cause ED or soft erections, either through reduced testosterone levels or just straight up tiredness. A 2023 study of male students found that those with poor sleep quality had a 59.9% higher prevalence of mild ED and a 19% prevalence of moderate ED, compared to those with good sleep quality. So, if you're not sleeping well, it's worth following the 3-2-1 rule to level up your sex life. For three hours before bed, try to avoid consuming food and alcohol, and instead stick to water or herbal tea. Peppermint brew, anyone?

This is why it seems like everyone has ADHD right now — including you

It might seem like 'everyone has ADHD right now' – but that couldn't be further from the truth (Picture: Metro) Opening up to a friend after I was diagnosed with ADHD, I voiced my struggles with time blindness, lateness, general disorganisation, and emotional dysregulation. 'But isn't it normal to get a little bit distracted sometimes? I probably have ADHD too, if that's the case' she said to me. My heart sank, feeling both rejected and my life experiences diminished in one simple interaction. I doubt she meant to upset me, but her words stung. There's an increasing perception that having ADHD is becoming a 'trend' or a 'personality quirk.' Just like OCD has been carelessly thrown about as being neat and tidy, ADHD is starting to become synonymous with making seemingly normal, harmless mistakes like misplacing a purse, or being 10 minutes late to a coffee date. As soon as I first read about ADHD in women, I knew that I had it. I once lost my house keys and paid my landlord for another set, only to find them wedged down the back of the sofa when I moved out. I also impulsively switched subjects during my GCSEs, A Levels and university; I had my library card revoked at the age of 10 after I failed to return the books I'd borrowed, and I'd spent my whole life feeling that my brain was simply a little bit different. So, does everyone really have ADHD now? Or are we just being equipped with the tools to navigate our own brains, and connecting with a like-minded community in the process? Have ADHD diagnoses increased in the last few years? In 2023, a study from UCL found that the number of people being diagnosed with ADHD has increased over the last 20 years, but this doesn't mean that 'everyone' has it now. Between 2000 and 2018, there was a twenty-fold increase in ADHD diagnoses, rising to almost fifty-fold in ADHD prescriptions issued to men aged 18-29. Largely owing to medical misogyny that favours research into symptoms in men and boys, women are still largely going undetected: the ADHD Foundation estimates that between 50 and 70% of the 1,000,000 women in the UK living with ADHD are undiagnosed. There might've been an increase in people seeking help for ADHD in recent years, but that doesn't mean that the condition is becoming more common. It still only impacts between 2% and 6% of the world's population. ADHD impacts between 2% and 6% of the population (Picture: Getty Images) Likewise, a 2025 review from King's College London looked at 40 studies across 17 countries and concluded that the prevalence of ADHD (AKA, the number of people living with a condition within a specific timeframe) hasn't increased since 2020. The author, Dr Alex Martin, noted that while much of the media has been concerned about a 'surge' in ADHD diagnoses, both 'assessments and help-seeking' are snowballing – which goes some way towards explaining why it might feel like more people have it now. There are also multiple barriers to diagnosis, including excessive NHS waiting times (as long as eight years in some parts of the UK), and the hefty cost of a private diagnosis, which averages out at £1,200 for adults. For many, self-diagnosis is their only option – and that's valid. Meeting the threshold for diagnosis Getting an ADHD diagnosis isn't an easy task, and psychiatrists certainly aren't handing them out like they're lollipops. To qualify, adults need to align with at least five symptoms on the DSM-5, the framework that's used to detect it. As psychologist and clinical director Dr Angela Pickering tells Metro, various symptoms of ADHD might seem relatable to the general non-neurodivergent public. But what differentiates these symptoms between being a normal part of life and being suggestive of neurodiversity is the frequency with which they happen and how debilitating they are. 'The key difference is that for someone with ADHD, these symptoms are persistent, pervasive and significantly impact their ability to function in daily life, across multiple settings such as work, school and relationships,' Dr Angela explains. ADHD isn't just being 'scatterbrained' or 'disorganised': in Angela's words, it's a 'neurodevelopmental condition rooted in differences in brain structure and function.' And so, a diagnosis doesn't just require checking off a few traits, but a 'detailed evaluation to understand the full context of a person's life and challenges.' As part of an ADHD assessment, psychiatrists will look at the pattern, intensity, and consistency of symptoms over time, even going as far as to ask a parent or family member to testify that their loved one's symptoms have longevity and started before the age of 12. When I was diagnosed in November 2021, I asked my mum to fill out the forms for me. Thankfully, she was able to recall with colour the school reports that were constantly telling me I was bright but needed to pay attention to detail and listen more; the eye tics that saw me blinking multiple times in a row, and my persistently hyperactive nature. I used to enjoy talking so much that I'd ask my parents if I could read my book aloud to them; my room was almost never tidy, and I had trouble paying attention in the classroom, often doodling into the line margins of my exercise books. So at the age of 23, I almost cried when I heard the words: 'you have combined ADHD' from my psychiatrist, as in one short moment, years of suffering were validated. Thankfully, I'd been able to skip the lengthy NHS waiting queue and had the cost of my private diagnosis funded through Right to Choose, so I was diagnosed within a matter of months, rather than years. Do you have ADHD, or is modern life just overwhelming? The reality is that, in the modern world, many of us will be feeling burnt out and overwhelmed by information. So, is it any surprise that we're increasingly distractible? As Dr Andrea explains: 'There's certainly growing evidence that people feel their environment – especially constant exposure to digital devices, social media and multitasking – can reduce attention spans and increase distractibility, even in people without ADHD.' With this in mind, the 'human brain simply didn't evolve to handle the level of information and stimulation we now face daily.' 'But while modern life can make anyone feel distracted, ADHD is a neurodevelopmental condition with symptoms that are consistent, long-standing and impairing across multiple areas of life,' she reminds us. So, whenever I hear people trivialising ADHD, I can't help but feel angry. It's not a quirky personality trait: it's an incredibly debilitating condition, and it's exhausting navigating a world designed by and for neurotypical people. ADHD isn't just losing your wallet or being a little bit 'scatty': it's so much more than that. Neurodiversity is finally in the limelight, and with awareness increasing, so many more people are sharing their stories. No doubt, it's saving lives. But the truth is that awareness without understanding is useless, and to suggest that 'everyone has it' diminishes the experiences of those who actually live with it. And no, it's not a 'superpower.' You don't have ADHD if you just forget your keys sometimes; you're probably just a regular human being living in an increasingly hectic world. Do you have a story to share?
