The foods you need to reduce to improve heart health
The study, published in Nature Metabolism, indicates that excess protein, especially the amino acid leucine found in animal sources, triggers mTOR signalling in immune cells crucial for arterial plaque formation.
Lead author Dr. Babak Razani identified 22 per cent of daily calories from protein as a risk threshold, though some experts, like cardiologist Dr. Stephen Tang, consider the study's scale too small for definitive conclusions.
Despite reservations about the study's size, Dr. Tang noted that the findings support a growing inclination among heart specialists towards plant-forward diets for improved cardiovascular health.
Current dietary guidelines suggest protein should make up 10 to 35 per cent of daily calories, with the American Heart Association endorsing plant-based proteins and advising limits on red and processed meats.

Gwyneth Paltrow appears in unusual Coldplay kiss-cam scandal response from Astronomer
Gwyneth Paltrow has made an unusual appearance in a video response from Astronomer after their CEO and head of HR were caught canoodling at a Coldplay concert causing an ' affair ' scandal. Paltrow, who is the ex-wife of Coldplay front-man Chris Martin, addresses questions in the tongue in cheek video that the business has received in the last week relating to the scandal by reeling off facts about the business instead. Astronomer's CEO Andy Byron and Head of HR Kristin Cabot, who have now both resigned, were panned to on the jumbotron 'kiss cam' and immediately hid from the camera. Chris Martin called it out at the time saying, "Either they're having an affair or their just really shy."

World's most premature baby celebrates first birthday
An Iowa toddler who was born when his mother was less than five months pregnant isn't only the most premature baby recognized by Guinness World Records after recently turning one. As his mother, Mollie Keen, put it, Nash Keen is also 'very determined, curious … and he's just all smiles all the time' after surviving against what Guinness described as 'phenomenal odds'. 'Nash is going to be able to … say, 'You know what? I came into this world fighting,'' the boy's father, Randall Keen, said in an interview that Guinness published Wednesday. ''And I'm going to leave fighting.'' The organization's database of about 40,000 records has long inspired fascination from the public. And Nash's path to that database began on 5 July 2024, when he was born at the gestational age of exactly 21 weeks in the University of Iowa Health Care Stead Family Children's hospital in Iowa City. Nash's birth came 133 days ahead of Mollie's expected due date, based on a typical full-term pregnancy of 280 days, an article on said. His birth was the second time in less than two years that Mollie had given birth prematurely. She recounted how she and Randall lost their daughter, McKinley, after she was born at a gestational age of nearly 18 weeks. After the couple became pregnant with Nash, 'we were so excited, but also very nervous,' Mollie said. 'We didn't get our hopes up.' Nash weighed only 10 ounces (283 grams), which is about the size of a soap bar, when he was born. He had to spend the next six months in the hospital's neonatal intensive care unit (NICU) before he was allowed to go home in January to Ankeny, Iowa. Mollie recalled to Guinness that she and Randall 'weren't sure if he'd even survive those first critical hours. But we wanted to give him the best chance.' The baby underwent 'highly specialized care, constant surveillance and frequent monitoring' while he faced a series of substantial 'challenges early on', Dr Amy Stanford – a neonatologist who helped care for Nash – told Guinness. Yet 'he showed remarkable resilience,' Stanford added. 'After those first few extremely delicate weeks, he began to make steady progress, which was truly extraordinary to witness.' As the Associated Press noted, Nash's story illustrates the growing number of extremely premature infants who are receiving life-saving treatment and surviving. Nash emerged from his NICU stay with as good an outcome as could be hoped for by medical science, as his doctors see it. At just over a year old, Nash still required oxygen to help him breathe, and he was nourished exclusively through a feeding tube. His parents had been preparing for him to try pureed foods. Nash's doctors were optimistic that a minor heart defect would resolve itself as he grew up. And he was not quite yet crawling, though he had started rolling over. None of those developmental realities had barred him from demonstrating his budding personality, Randall told Guinness. 'Whenever you call him 'Nash potato', or you cheer him on when he's trying to pull himself up … he just hams it up,' Randall said. 'It makes him want to succeed and do more.' A small gathering of family close friends joined Nash and his family to celebrate his first birthday. He was feted with new outfits, educational toys, diapers and the certificate from Guinness – now that he had beaten out by a single day the organization's previous most premature baby record holder, who was born in 2020 in Alabama. Mollie told Guinness she and Randall are as happy as Nash has been. 'I love waking up to him,' she remarked. 'He's truly … the best thing that could have happened to us.' AP contributed reporting
