Over half of US calories are from ultra-processed foods
Nutrition research has shown for years that ultra-processed foods make up a big chunk of the US diet, especially for kids and teens.
For the first time, the US Centers for Disease Control and Prevention has confirmed those high levels of consumption, using dietary data collected from August 2021 to August 2023.
Overall, about 55 per cent of total calories consumed by Americans age one and older came from ultra-processed foods during that period, according to the report. For adults, ultra-processed foods made up about 53 per cent of total calories consumed, but for kids through age 18, it was nearly 62 per cent.
The top sources included burgers and sandwiches, sweet baked goods, savory snacks, pizza and sweetened drinks.
Young children consumed fewer calories from ultra-processed foods than older kids, the report found. Adults 60 and older consumed fewer calories from those sources than younger adults. Low-income adults consumed more ultra-processed foods than those with higher incomes.
The results were not surprising, said co-author Anne Williams, a CDC nutrition expert.
What was surprising was that consumption of ultra-processed foods appeared to dip slightly over the past decade. Among adults, total calories from those sources fell from about 56 per cent in 2013-2014 and from nearly 66 per cent for kids in 2017-2018.
Williams said she couldn't speculate about the reason for the decline or whether consumption of less processed foods increased.
Concern over ultra-processed foods' health effects has been growing for years, but finding solutions has been difficult. Many studies have linked them to obesity, diabetes and heart disease, but they haven't been able to prove that the foods directly cause those chronic health problems.
One small but influential study found that even when diets were matched for calories, sugar, fat, fibre and micronutrients, people consumed more calories and gained more weight when they ate ultra-processed foods than when they ate minimally processed foods.
Research published this week in the journal Nature found that participants in a clinical trial lost twice as much weight when they ate minimally processed foods - such as pasta, chicken, fruits and vegetables - than ultra-processed foods.
Part of the problem is simply defining ultra-processed foods.
The new CDC report used the most common definition based on the four-tier Nova system developed by Brazilian researchers that classifies foods according to the amount of processing they undergo. Such foods tend to be "hyperpalatable, energy-dense, low in dietary fibre and contain little or no whole foods, while having high amounts of salt, sweeteners and unhealthy fats," the CDC report said.
US health officials recently said there are concerns over whether current definitions "accurately capture" the range of foods that may affect health. The US Food and Drug Administration and the Agriculture Department recently issued a request for information to develop a new, uniform definition of ultra-processed foods for products in the US food supply.
Most Americans get more than half their calories from ultra-processed foods, those super-tasty, energy-dense foods typically full of sugar, salt and unhealthy fats, according to a new report.

Passenger reveals what caused diarrhoea that stopped a plane
An American nanny who went viral for her airplane diarrhoea horror story has revealed the true cause behind the mortifying incident. Meghan Reinertsen, 29, was aboard a United Airlines flight from Newark to Indianapolis in the United States when she experienced 'biohazard diarrhoea', resulting in a hazmat crew boarding the plane and the next flight being cancelled. A TikTok she posted about the experience, which has now had more than 20 million views, spoke about the July 2024 incident in detail. 'I (was) in agonising pain, I (was) just full body sweating, crying, my insides cramping,' she said in the clip. If you'd like to view this content, please adjust your . To find out more about how we use cookies, please see our Cookie Guide. While social media comments and news outlets were quick to attribute Reinertsen's situation to norovirus, she has since confirmed the cause was something a lot simpler … food poisoning from a hamburger. 'I had eaten part of an undercooked burger before I left to get back to Indiana,' she confessed to the Daily Mail, saying she had only consumed a couple of bites of the bloody patty. Although most cases don't occur in a United Airlines plane toilet, Ms Reinertsen's mid-flight gastrointestinal struggle isn't that uncommon. Meghan Reinertsen's bathroom dilemma was caused by an undercooked burger consumed before the flight. Credit: @meghanreinertsen / Instagram According to the Centre For Disease Control And Prevention, one in seven Americans experience food poisoning annually with 128,000 people admitted to hospital due to the condition every year. In the video, Ms Reinertsen reported the 'disturbance' in her stomach developed five hours into the flight, which aligns with the usual onset of foodborne illnesses. Food poisoning symptoms typically start anywhere from two to six hours after a person has consumed the offending item. Despite the tale of her destructive diarrhoea being seen by millions, Ms Reinertsen hasn't let the experience phase her — saying she is able to enjoy the humorous side of her bathroom battle and is grateful her video was able to bond people over similar experiences. 'I have had an egregious amount of people reach out to me with their own plane horror stories, which I love to hear,' Ms Reinertsen told the Daily Mail. 'I'm happy that I have been able to make people feel better about their own situations.'

Ask Fuzzy: What were Dr Williams' Pink Pills?
In 1899, what could best be described as an advertorial appeared in The Geelong Advertiser. The claims it made were astonishing and, if only half of them were true, everybody should be taking Dr William's Pink Pills For Pale People. The list of ailments for which it promised "certain cure" was apparently limitless: indigestion, pimples, skin diseases, liver and kidney troubles, biliousness, anaemia, sleeplessness, rheumatism, lumbago, loss of physical strength, neuralgia... Women should be especially keen because it included "all female irregularities", whatever that meant. If that wasn't enough, it was said to cure "debility" and "sick headaches", but they kept the best till last: "loss of vital forces". Indeed, one wonders why billions of dollars on medical research since then has been necessary since the Pink Pills would doubtlessly also cure COVID and AIDS. Dr Williams, of course, was just one in a long tradition of snake oil companies harvesting money from gullible people. The quack cure originated in Canada in the late 1800s and was marketed in numerous countries around the world, including Australia. In an early example of using influencers, advertisers enlisted prominent people to endorse their product. One (probably fictitious) Dr Guiseppi Lapponi - "Physician to the Vatican" - proclaimed that he had used Dr Williams' Pink Pills in his practice "with good results". Oddly enough, the pills might actually be helpful for "pale people" with anaemia. A 1909 examination by the British Medical Association found, along with liquorice and sugar, they contained iron supplements. Unfortunately, a third of the iron in the pink sugar-coated pills had oxidised. The pills, they noted, had been "very carelessly prepared". MORE ASK FUZZY: Pill contents varied over time, and some variants included aloe laxatives. There were, however, concerns and, to control fake medicines, Theodore Roosevelt passed the 1906 Pure Food and Drug Act, which led to the establishment of the Food and Drug Administration. That forced vendors to list active ingredients' purity levels on labels. While that may have had some effect, shelves today are lined with products that tap into nutrition anxiety. Concoctions promise "anti-aging" and "fusion health". They will even "fuel your cells"! In a curious coda to this story, George Fulford of G. T. Fulford & Company, who marketed the pills, died in a car accident in 1905, making him the first Canadian on record to die by automobile accident.

The 'deceptive' drug that's ravaging parts of the US
Your web browser is no longer supported. To improve your experience update it here Kratom, a natural supplement derived from a tree native to South-east Asia, is getting a lot of attention in the US because it's highly addictive, and many people who think it's perfectly safe are finding themselves unable to stop using it. Alabama is one of only a few states where it's illegal, but it is still a problem here. Angela Edwards is living and working at the Lovelady Centre in Birmingham, the state's capital; she's dealing with addiction, and most recently, her drug of choice was kratom. Kratom is a deceptive drug that is causing problems in US states like Alabama. (CNN) "Every day. I was taking it every day. All day," she said. Experts call it a deceptive drug, because it's plant-based and all natural, there's the belief it must be safe; it's even marketed as an alternative to alcohol. Frank Long, with the Lovelady Centre said, "It's an opioid-like effect. You know, some people describe it like a warm hug. "You know, it's kind of that feeling of peacefulness and that everything's OK. "Or maybe you just don't care about anything. "So, it kind of makes you forget your worries." Long said it's highly addictive and users quickly develop a tolerance to it, so they're compelled to use more and more to get the same effect. And when they try to quit, withdrawal symptoms are reportedly worse than those associated with coming off heroin. "I was on kratom for about two years, if not longer," Edwards said. "And at the time when I was on kratom, you know, it was good when I was on it, but when I was coming off kratom, I thought I was going to die, you know, the withdrawals were worse than any kind of withdrawals that I've ever had." An estimated 1.7 million Americans 12 and older used kratom in 2021, according to the Substance Abuse and Mental Health Services Administration's National Survey on Drug Use and Health. Kratom is often consumed in tablet form. (AP) In July, the Food and Drug Administration recommended a scheduling action to control certain 7-hydroxymitragynine (also known as 7-OH) products under the Controlled Substances Act. Kratom is illegal in Alabama, but Long said manufacturers have created synthetic versions, and by changing just one molecule, they can skirt the law and sell the products here. Edwards has been sober for a while now, but she's not out of the woods. "It took me months to feel even normal. I still don't have my full energy back," she said. Her advice to anyone thinking this might be a good idea? "Don't do it. It's not, it's not worth it, it's not worth it." CONTACT US
