AI deepfakes of real doctors spreading health misinformation on social media

1 day ago

TikTok and other social media platforms are hosting AI-generated deepfake videos of doctors whose words have been manipulated to help sell supplements and spread health misinformation.The factchecking organisation Full Fact has uncovered hundreds of such videos featuring impersonated versions of doctors and influencers directing viewers to Wellness Nest, a US-based supplements firm.All the deepfakes involve real footage of a health expert taken from the internet.However, the pictures and audio have been reworked so that the speakers are encouraging women going through menopause to buy products such as probiotics and Himalayan shilajit from the company’s website.The revelations have prompted calls for social media giants to be much more careful about hosting AI-generated content and quicker to remove content that distorts prominent people’s views.

“This is certainly a sinister and worrying new tactic,” said Leo Benedictus, the factchecker who undertook the investigation, which Full Fact published on Friday,He added that the creators of deepfake health videos deploy AI so that “someone well-respected or with a big audience appears to be endorsing these supplements to treat a range of ailments”,Prof David Taylor-Robinson, an expert in health inequalities at Liverpool University, is among those whose image has been manipulated,In August, he was shocked to find that TikTok was hosting 14 doctored videos purporting to show him recommending products with unproven benefits,Though Taylor-Robinson is a specialist in children’s health, in one video the cloned version of him was talking about an alleged menopause side-effect called “thermometer leg”.

The fake Taylor-Robinson recommended that women in menopause should visit a website called Wellness Nest and buy what it called a natural probiotic featuring “10 science-backed plant extracts, including turmeric, black cohosh, Dim [diindolylmethane] and moringa, specifically chosen to tackle menopausal symptoms”.Female colleagues “often report deeper sleep, fewer hot flushes and brighter mornings within weeks”, the deepfake doctor added.The real Taylor-Robinson discovered that his likeness was being used only when a colleague alerted him.“It was really confusing to begin with – all quite surreal,” he said.“My kids thought it was hilarious.

“I didn’t feel desperately violated, but I did become more and more irritated at the idea of people selling products off the back of my work and the health misinformation involved,”The footage of Taylor-Robinson used to make the deepfake videos came from a talk on vaccination he gave at a Public Health England (PHE) conference in 2017 and a parliamentary hearing on child poverty at which he gave evidence in May this year,In one misleading video, he was depicted swearing and making misogynistic comments while discussing menopause,TikTok took down the videos six weeks after Taylor-Robinson complained,“Initially, they said some of the videos violated their guidelines but some were fine.

That was absurd – and weird – because I was in all of them and they were all deepfakes,It was a faff to get them taken down,” he said,Full Fact found that TikTok was also carrying eight deepfakes featuring doctored statements by Duncan Selbie, the former chief executive of PHE,Like Taylor-Robinson, he was falsely shown talking about menopause, using video taken from the same 2017 event where Taylor-Robinson spoke,One video, also about “thermometer leg”, was “an amazing imitation”, Selbie said.

“It’s a complete fake from beginning to end.It wasn’t funny in the sense that people pay attention to these things.”Sign up to First EditionOur morning email breaks down the key stories of the day, telling you what’s happening and why it mattersafter newsletter promotionFull Fact also found similar deepfakes on X, Facebook and YouTube, all linked to Wellness Nest or a linked British outlet called Wellness Nest UK.It has posted apparent deepfakes of high-profile doctors such as Prof Tim Spector and another diet expert, the late Dr Michael Mosley.Wellness Nest told Full Fact that deepfake videos encouraging people to visit the firm’s website were “100% unaffiliated” with its business.

It said it had “never used AI-generated content”, but “cannot control or monitor affiliates around the world”.Helen Morgan, the Liberal Democrat health spokesperson, said: “From fake doctors to bots that encourage suicide, AI is being used to prey on innocent people and exploit the widening cracks in our health system.“Liberal Democrats are calling for AI deepfakes posing as medical professionals to be stamped out, with clinically approved tools strongly promoted so we can fill the vacuum.“If these were individuals fraudulently pretending to be doctors they would face criminal prosecution.Why is the digital equivalent being tolerated?“Where someone seeks health advice from an AI bot they should be automatically referred to NHS support so they can get the diagnosis and treatment they actually need, with criminal liability for those profiting from medical disinformation.

”A TikTok spokesperson said: “We have removed this content [relating to Taylor-Robinson and Selbie] for breaking our rules against harmful misinformation and behaviours that seek to mislead our community, such as impersonation.“Harmfully misleading AI-generated content is an industry-wide challenge, and we continue to invest in new ways to detect and remove content that violates our community guidelines.”The Department of Health and Social Care was approached for comment.The best public interest journalism relies on first-hand accounts from people in the know.If you have something to share on this subject, you can contact us confidentially using the following methods.

Chocolate tart and zabaglione: Angela Hartnett’s easy make-ahead Christmas desserts – recipes

When you’re the cook of the house, you spend quite enough time in the kitchen on Christmas Day as it is. And, after those time-consuming nibbles, the smoked salmon starter and the turkey-with-all-the-trimmings main event, the last thing you want is a pudding that demands even more hands-on time at the culinary coalface. For me, the main requirement of any Christmas dessert is that it can be made well in advance, not least because, by the time the pudding stage comes around, I’ll be completely knackered and more than ready to put up my feet and finally relax (or, more likely, fall asleep on the sofa).Prep 15 minRest 3 hr+Cook 40 minServes 6-8For the sweet pastry500g plain flour, plus extra for dusting 150g caster sugar 250g cold butter, diced2-3 eggs, lightly beatenFor the filling640g 70%-cocoa dark chocolate, broken into small pieces800ml double cream 64g glucose syrup 64g cold butter, cubed 100g roasted hazelnuts, lightly choppedPut the flour and sugar in a large bowl, stir to combine, then add the diced butter and work it in with your fingertips until the mix takes on the consistency of rough breadcrumbs. Add two of the beaten eggs, then mix until the dough comes together into a ball; if need be, add the third beaten egg, but take great care not to overwork the dough

I called my recipe book Sabzi – vegetables. But the name was trademarked. And my legal ordeal began

Vegetables, in my experience, rarely cause controversy. Yet last month I found myself in the middle of a legal storm over who gets to own the word sabzi – the Hindi, Urdu, Punjabi, Persian, Dari and Pashto word for cooked veg or fresh greens. It was a story as absurd as it was stressful, a chain of delis threatened me with legal action over the title of a book I had spent years creating. But what began as a personal legal headache soon morphed into something bigger, a story about how power and privilege still dominate conversations about cultural ownership in the UK.When the email first landed in my inbox, I assumed it must be a wind-up

Choice taste test: the best Australian supermarket Christmas ham is also ‘one of the cheapest’

Consumer advocacy group Choice has found when it comes to supermarket Christmas hams, pork price is not necessarily an indicator of quality.In a blind taste test of 12 Christmas hams from Aldi, Coles, IGA and Woolworths, the best and worst-ranked pork products retail at almost identical prices.The best-scoring product was the Coles Christmas Beechwood Smoked Half Leg Ham, with a price per unit of $8/kg. Judges awarded it a score of 80% and described it as a “good overall ham” for its “mild but pleasant” aroma with “a nice balance between sweet and smoky flavours”.The worst-performing product, the Aldi Festive Selection Australian Half Leg Ham On-The-Bone, is similarly priced at $7

How to turn excess nuts and seeds into a barnstoming festive pudding – recipe | Waste not

Last Christmas we visited my in-laws in Cape Town, where, at over 30C, a traditional Christmas pudding just didn’t feel quite right. But my mother-in-law and her friend created the most delicious feast: a South African braai (barbecue) followed by an incredible ice-cream Christmas pudding made by mashing vanilla ice-cream with a mix of tutti frutti, candied peel, raisins and cherries. This semifreddo is a take on that dessert: a light frozen custard that still carries all the festive flavours.Tutti frutti semifreddo Christmas puddingWe stopped using clingfilm in our kitchen 15 years ago now, because it’s not easily recycled and because of health concerns about the possible transfer of microplastics into our food. Most semifreddo recipes tell you to line the freezer container with clingfilm, but I suggest using no liner at all, or silicone-free, unbleached baking paper instead

The great Christmas taste test: I tried seven fast food offerings. Which will make me feel festive?

From a cranberry katsu curry to a dozen thickly glazed doughnuts, the biggest chains are getting Christmassy. I found out which seasonal meals will leave you carolling and carousing – and which will leave you coldBy now, most major fast food outlets will have launched their festive special. There is no established framework for what “festive” means, and no recognised metrics of Christmassyness. It could be indicated by a lurid green/angry red colour in a place you’re not expecting it (McDonald’s Grumble Pie, I’m looking at you); or an existing thing, made into a more seasonal shape, or the introduction of a quintessential Christmas ingredient, such as a brussels sprout (though seriously, food giants, get over yourself if you think it’s cinnamon – this is an autumn spice).I am not here to critique the essentials of fast food (I love it)
