New study shows devastating impact of ultra-processed foods — and the packaged food industry isn't happy about it
Ultra-processed foods — which often contain high levels of sugar, salt and unhealthy fats — are believed to make up over 70% of the US food supply.
A new analysis examined data from the US and seven other countries to estimate the percentage of premature, preventable deaths due to the consumption of UPFs like packaged snacks, sugary drinks, processed meats and sweetened breakfast cereals.

'We looked at the risk of a person dying from eating more ultra-processed foods between the ages of 30 and 69, a time when it would be premature to die,' study co-author Carlos Augusto Monteiro, emeritus professor of nutrition and public health in the School of Public Health at Brazil's University of São Paulo, told CNN.
Monteiro's team found that the risk of early death rises by nearly 3% for every 10% increase in calories from UPFs. The findings were published Monday in the American Journal of Preventive Medicine.
Prior research has linked UPFs to 32 negative health outcomes, including elevated risks of heart disease, cancer, Type 2 diabetes and mental health woes.
Some 124,000 premature US deaths were attributable to UPF consumption in 2018, said Eduardo Augusto Fernandes Nilson, lead investigator of the new study.
Fernandes Nilson and his colleagues built a computer model that estimated percentages of UPF-related early deaths based on data from nearly 240,000 people and almost 15,000 deaths.

The results ranged from 4% in countries with lower UPF consumption (Colombia) to almost 14% in countries with higher UPF consumption (the UK and US).
The other countries studied were Brazil (low consumption), Chile and Mexico (intermediate) and Australia and Canada (high).
'The findings support that ultra-processed food intake contributes significantly to the overall burden of disease in many countries, and its reduction should be included in national dietary guideline recommendations and addressed in public policies,' the researchers wrote in their paper.
However, the study could not determine if the deaths were 'caused by UPF consumption,' nutrition scientist Nerys Astbury — an associate professor of diet and obesity at the UK's University of Oxford who was not involved in the study — pointed out to CNN.
The research also drew criticism from Sarah Gallo — senior vice president of product policy for the Consumer Brands Association, which represents the food industry.
'This is another example of a misleading study that will ultimately lead to consumer confusion. Currently, there is no scientific agreement on the definition of ultra-processed foods,' Gallo said.
'Demonizing convenient, affordable and shelf-ready food and beverage products could limit access to and cause avoidance of nutrient-dense foods, resulting in decreased diet quality, increased risk of food-borne illness and exacerbated health disparities.'

Opioids: Parasitic Worm Discovery Could Lead to Safer Painkillers
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The evolutionary trick of parasitic worm that sneakily burrows into the skin of its victims could provide new alternatives to opioid-based pain treatments. Opioids are currently used to treat moderate to severe pain, as well coughing and diarrhea. Although they can provide effective relief, long-term use can also lead to dependence, with negative physical and mental health consequences. Researchers discovered that the worm—Schistosoma mansoni—suppresses neurons in the skin to evade detection in a mechanism likely developed to enhance its own survival. The molecules responsible for this suppression of sensation could help in the development of new painkillers, according to the team at the Tulane School of Medicine. Schistosomiasis is a parasitic infection caused by helminths, a type of worm known to survive in their mammal hosts for many years. Their larvae can infest freshwater bodies like lakes, ponds and rivers—infecting people who, for example, swim, fish or wash clothes in the water. "While bacteria often cause painful cutaneous reactions, host skin invasion by the human parasitic helminth Schistosoma mansoni often goes unnoticed," the researchers wrote in their paper. Medical microscopy showing parasite. Medical microscopy showing parasite. defun/Getty Images S. mansoni often evades detection by the immune system, unlike other bacteria or parasites that cause pain, itching or rashes—a feat the team set out to investigate. After conducting experiments on mice, the researchers found that S. mansoni produces molecules that suppress the activity of TRPV1+, a protein used to send signals that the brain interprets as heat, itching or pain. As part of the pain-sensing process in sensory neurons, TRPV1+ regulates immune responses in scenarios including allergy, autoimmunity, cancer, infection and even hair growth, the researchers explained. It is likely the parasitic worm evolved its ability to block TRPV1+ because it enhance its survival, the researchers said. "If we identify and isolate the molecules used by helminths to block TRPV1+ activation, it may present a novel alternative to current opioid-based treatments for reducing pain," said paper author and immunologist professor De'Broski R. Herbert| in a statement. "The molecules that block TRPV1+ could also be developed into therapeutics that reduce disease severity for individuals suffering from painful inflammatory conditions." Open spillage bottle of opioid pain killing tablets. Open spillage bottle of opioid pain killing tablets. BackyardProduction/Getty Images The study also revealed that TRPV1+ is necessary for initiating host protection against S. mansoni. Activation of the protein leads to rapid mobilization of immune cells, including gd T cells, monocytes and neutrophils, which induce inflammation. This inflammation, the researchers explained, plays a crucial role in host resistance to the larval entry into the skin. These findings highlight the importance of neurons that sense pain and itching in successful immune responses. "Identifying the molecules in S. mansoni that block TRPV1+ could inform preventive treatments for schistosomiasis. We envision a topical agent which activates TRPV1+ to prevent infection from contaminated water for individuals at risk of acquiring S. mansoni," said Herbert. In the study, mice were infected with S. mansoni and evaluated for their sensitivity to pain as well as the role of TRPV1+ in preventing infection. "S. mansoni infection significantly reduced thermal pain sensitivity evoked by TRPV1+ neurons. Consistently, isolated skin sensory neurons from infected mice had significantly reduced calcium influx and neuropeptide [chemical messenger] release in response to the TRPV1 agonist capsaicin [an irritant for humans and mammals] compared to neurons from naïve controls," the study authors wrote. "Using gain-and loss-of-function approaches to test whether TRPV1+ neurons initiate host-protective responses revealed that TRPV1+ neurons limit S. mansoni skin entry and migration into the pulmonary tract." The researchers are now planning to identify the nature of the secreted or surface-associated helminth molecules that are responsible for blocking TRPV1+ activity and specific gd T cell subsets that are responsible for immune responses. They also seek to further understand the neurons that helminths have evolved to suppress. Newsweek has reached out to the researchers for additional comment.

What Is Creatine? The Gym Bro Supplement Is Suddenly Everywhere
It's the most studied supplement in sports medicine, but it's not just for athletes anymore. Courtesy of Amazon; Getty Images; Thorne All products featured on WIRED are independently selected by our editors. However, we may receive compensation from retailers and/or from purchases of products through these links. Learn more. First, it was mushrooms in your coffee. Then protein in your soda. The latest wellness staple sneaking into your pantry is creatine. In the days of yore, creatine supplements were a muscle-bro staple, relegated to the lockers of collegiate linebackers and bodybuilders. Lately, it has muscled its way into Pilates studios, gym girlies' TikToks, and longevity wellness retreats. This content can also be viewed on the site it originates from. 'Creatine has been gaining popularity among women across different age groups,' says Gretchen Zimmermann, a registered dietitian. 'We do see women who are lifting heavier, and there used to be this thing that was circulating a decade or two ago, where women thought that if they lifted heavy, they would get bulked up. Now we know that's not true, and naturally there's some interest in creatine for that reason.' But what is creatine? Here's everything you need to know. Creatine is a compound your body produces in the liver, kidneys, and pancreas, according to Federica Amati, a medical scientist and registered public health nutritionist. Most of it ends up in your skeletal muscles, where it's stored as phosphocreatine and used to regenerate adenosine triphosphate (ATP), the molecule that powers muscle contractions, nerve signals, and protein synthesis for tissue repair. The rest—less than 5 percent—is found in brain tissue and the testes. You make about a gram of creatine a day from three amino acids: arginine, glycine, and methionine. You also get more from animal-based foods like red meat, fish, and poultry. For most healthy people, that's enough. So, creatine supplements aren't essential for general health, but they can boost performance and recovery under the right conditions. Photo by Steve Mitchell/EMPICS via Getty Images ATP is your cells' main energy source. High-intensity exercise drains it fast, breaking ATP down into adenosine diphosphate (ADP). Creatine phosphate donates a phosphate group to ADP, recycling it back into ATP almost immediately. The more phosphocreatine stored in your muscles, the faster you can regenerate ATP and the more power you can produce in short bursts. Creatine is most useful for activities that demand short, intense effort: sprinting, weightlifting, and high-intensity interval training, to name a few. It's far less relevant for endurance sports like marathons. Some evidence suggests creatine also increases muscle glycogen storage, which could help with recovery and energy replenishment between sessions. Creatine doesn't directly build muscle, but paired with resistance training and adequate nutrition, it can help preserve muscle strength and lean body mass. It's particularly important if you're recovering from an injury, or as you age, when sarcopenia (age-related muscle loss) becomes a risk, as it activates specialized stem cells known as satellite cells. Zimmerman points out that women, especially in perimenopause and menopause, may see health benefits. 'As women get older—starting in our forties—we lose body mass 1 to 2 percent a year, and that can affect bone health later on in life,' says Zimmermann. 'Creatine [supplements] support keeping and building lean muscle mass.' Zimmermann adds, 'Women tend to have lower muscle mass than men, just naturally, so I think women may actually respond better to supplementation, because they're at baseline.' While the effects of creatine supplementation on athletic performance are well-documented, its effects on mental performance are still emerging. Early findings are promising. Studies suggest it may reduce mental fatigue, especially during high-stress situations, such as sleep deprivation or exhaustive exercise. It may also improve certain aspects of memory, particularly in groups with lower baseline creatine levels, such as vegetarians and older adults. Some preliminary research even suggests it could help with symptoms of depression by supporting brain energy and boosting the production of feel-good neurotransmitters like dopamine and serotonin. That's particularly relevant for women experiencing perimenopause and menopause, says Zimmerman. 'Estrogen shifts affect brain health, our mood, brain fog, and being able to think clearly.' Nowadays, step into any GNC and you'll find several forms of creatine: creatine hydrochloride, magnesium creatine chelate, creatine citrate, creatine nitrate, creatine ethyl ester, and buffered creatine. But creatine monohydrate is the most studied, the most effective, and usually the cheapest, according to the International Society of Sports Nutrition. No other form has shown any additional benefits, confirms Amati. Creatine monohydrate is typically sold as a flavorless, white powder that you can mix into water or a shake. The standard dose is three to five grams per day, says Amati. Some athletes may 'load' with higher doses, but studies show this offers no long-term benefits and can put unnecessary stress on the kidneys, says Amati. For most healthy adults, creatine is a safe and well-tolerated supplement for months or even years of use. Short-term and long-term clinical trials have found no significant health risks. The main side effects are minor: weight gain from temporary water retention in the first week of supplementation, bloating, and mild gastric discomfort, usually from oversize doses.
