Irregular sleep patterns may be linked to harmful bacteria in your gut, new research suggests. The study is the first to find multiple associations between social jet lag – the shift in internal body clock when sleeping patterns change between workdays and free days – and diet quality, diet habits, inflammation and gut microbiome (bacteria) composition. According to the findings, even a 90-minute difference in the midpoint of sleep – half-way between sleep time and wake-up time – can encourage microbiome that has negative associations with health. Previous research has suggested that working shifts disrupts the body clock and can increase risk of weight gain, heart problems and diabetes. This is the first study to show that even small differences in sleep timings across the week seems to be linked to differences in gut bacterial species Dr Wendy Hall King’s College London However, according to researchers from King’s College London there is less awareness that the body’s biological rhythms can be affected by smaller inconsistencies in sleeping patterns. This is due to people working regular hours waking early with an alarm clock on workdays compared to waking naturally on non-workdays. Senior author Dr Wendy Hall from King’s College London, said: “We know that major disruptions in sleep, such as shift work, can have a profound impact on your health. “This is the first study to show that even small differences in sleep timings across the week seems to be linked to differences in gut bacterial species. “Some of these associations were linked to dietary differences but our data also indicates that other, as yet unknown, factors may be involved. “We need intervention trials to find out whether improving sleep time consistency can lead to beneficial changes in the gut microbiome and related health outcomes.” First author Kate Bermingham, from King’s College London and senior nutrition scientist at ZOE, said: “Sleep is a key pillar of health, and this research is particularly timely given the growing interest in circadian rhythms and the gut microbiome. “Even a 90-minute difference in the mid-point of sleep can encourage microbiota species which have unfavourable associations with your health.” Researchers suggest the composition of the microbes in the gut may negatively or positively affect health by producing toxins or beneficial products. Specific species of microbes can correspond to an individual’s risk of long-term health conditions such as diabetes, heart disease and obesity. The microbiome is influenced by what food someone eats, which makes the diversity of the gut adjustable. Researchers assessed a group of 934 people from the ZOE Predict study, the largest ongoing nutritional study of its kind. They looked at blood, stool and gut microbiome samples, as well as glucose measurements in people whose sleep was irregular compared to those who had a routine sleep schedule. Unlike past research, the group consisted of mainly lean and healthy individuals with most of them getting more than seven hours sleep throughout the week. The study, published in The European Journal of Nutrition, found that just a 90-minute difference in the timing of the midpoint of sleep is associated with differences in what the gut microbiome is made up of. According to the findings, having social jet lag was associated with lower overall diet quality, higher intakes of sugar-sweetened beverages, and lower intakes of fruits and nuts. This may directly influence the abundance of specific microbiota in the gut, researchers say. Three out of the six microbiota species more abundant in the social jet lag group have what researchers describe as unfavourable associations with health. They are linked with poor diet quality, indicators of obesity and cardiometabolic health, like heart attack, stroke, and diabetes, and markers in your blood related to higher levels of inflammation and cardiovascular risk. Previous research has found social jet lag is associated with weight gain, chronic illness and mental fatigue. Dr Sarah Berry from King’s College London and chief scientist at ZOE added: “Maintaining regular sleep patterns, so when we go to bed and when we wake each day, is an easily adjustable lifestyle behaviour we can all do, that may impact your health via your gut microbiome for the better.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live N-Dubz cement comeback with first new album in 13 years Babies as young as four months have taste in fine art, study shows ADHD symptoms in children can be transformed with brain stimulation therapy

SALINAS, Calif.--(BUSINESS WIRE)--Sep 21, 2023--

A 20-year-old has swapped veganism for raw meat, eating uncooked items including beef, chicken, heart and liver on a daily basis for the past four years, and claims he has “never gotten sick”. Jones Hussain, from Stockholm, Sweden, has eaten raw chicken as well as raw cuts of beef, minced meat and fish, without batting an eyelid – even if they are brown or smell slightly. He says he would happily eat any kind of meat provided it is good quality, from “wild boar to camel” but that he prefers minced beef because it is cheap, accessible and does not smell compared with chicken. Jones took the decision to eat raw meat just a few months after quitting veganism in 2019 “in the name of health” after he watched a YouTube video with the late American alternative food nutritionist, Aajonus Vonderplanitz, whose “Primal Diet” has inspired people worldwide. Health has always been important for Jones, who supplements his raw meat diet with fruit and juiced vegetables. He said he would not eat cake for £10,000 because of the sugar and claims to have not had a slice since the age of 13. “If any food safety expert looked at the food I eat, I think they would have a heart attack because the beef is sometimes brown, the liver looks green, the chicken stinks,” Jones told PA Real Life. “But I eat that and then nothing happens. “I did the experiments on myself to see whether what we have been led to believe is actually true and surprise, surprise, it wasn’t.” Jones, who said he has always been driven by “health”, came across the raw meat diet plan in 2019 a few months after quitting veganism. “My starting point has always been health,” he said. “So I’ve experimented with a bunch of things in the name of health.” The diet was designed by Vonderplanitz, who touted the benefits of eating raw foods, in particular meat and dairy. “I found one of his lectures on YouTube and started listening,” he said. “At first, I was just as shocked as anyone would be to see someone eat such a diet.” But Jones said he found Vonderplanitz’s arguments to be “honest and convincing” and so decided to give it a try. “I ate raw meat for the first time in November 2019 and I felt great,” he said. “It was just a straight cut of raw beef.” Having not fallen ill, Jones then decided to try raw ground beef. “That was the scary part because that’s when you enter into uncharted territory,” he said. “I was like, if I get sick then I won’t do this anymore. “Lo and behold, again, I didn’t get sick, so I started eating raw ground beef because it’s much cheaper than straight cuts.” To start with, Jones would flavour the raw meat with spices and garlic. “But then I felt that I didn’t need them, even from a taste perspective,” he said. “So I just started consuming it by itself and ever since then I’ve eaten raw ground beef almost every day.” By the summer of 2020, Jones had become accustomed to eating all types of meat. “I had no problems eating raw chicken because I had found a fairly good source in the supermarket so I ate it like KFC,” he said. “I also started buying raw liver here and there, and eating a small amount every day.” The raw meat Jones kept in his fridge soon started to turn “green”, but this did not stop him from eating it. “Since I was so convinced about what Aajonus was saying, I was not worried and just consumed it,” he said. “But if there was any white mould, then I got rid of the batch, although this did not happen very often.” Jones has continued eating raw meat ever since, although his family prefers ground beef to chicken because of the smell. “Nowadays I don’t so much eat raw chicken because it stinks up the house,” he said. In a single sitting, Jones said he is capable of consuming around 400g of raw liver. He said he believes dumping veganism for raw meat has improved his gut health and helped get rid of his acne. “The thing with raw meat is that the nutrients are more easily absorbed and unaltered,” he claimed. “It’s not that raw meat has some kind of special super power, it’s just that by not cooking it, I get more nutrients and no byproducts.” NHS guidelines, however, state that “cooking meat properly” kills harmful bacteria which can cause food poisoning. Jones had been a vegan for two years, from 2017 to 2019, before eventually converting to the primal diet. “It’s not that I was struggling to get enough nutrients,” he said. “It’s that a human being cannot survive on a vegan diet successfully. “Of course you can take supplements but it’s not the same thing, because they are processed. “There is no other way of getting these nutrients naturally other than by eating animal products. “So veganism on that basis, falls on its face.” Jones also eats raw fish such as salmon and tuna and said he is happy to eat any type of meat provided he can find a reliable supplier. The Primal Diet also includes fruit and vegetables, all of which are consumed raw. “I eat cucumbers and tomatoes, as well as oranges and apples when they are available to me,” he said. “The philosophy is don’t cook the food, but there is a variety.” Jones’ unusual diet often shocks people, including his parents who are concerned for his wellbeing. He explained: “Usually people have the same reaction, at first they think what the hell is this guy doing? He’s going to die in a few days. “Then they speak to me and find out that I’ve been doing it for three and half years, that I’ve never gotten sick, that my arguments are logical and that I look healthy. “They are like all right, that’s a new perspective that I had not heard before.” People behave differently on social media, however, said Jones, who has his own YouTube channel, Excellent Health. He also works part time at an elderly day care centre and has written a book titled The 6 Health Commandments. “The only time I ever got food poisoning was from a frozen bag of raspberries before I started eating meat,” he said. “I decided not to act out of fear, but to see what is true and what isn’t true.” To find out more about food safety, visit www.food.gov.uk/safety-hygiene/cooking-your-food.
