And as Instagram constitutes the largest audience for this content, we've shared letter there too, linked below. In case you don't use that, here's the FAQ we added in response to a barrage of trolling. www.instagram.com/p/Dd0pvudCKG...

As a result, we're making the text of the letter public. While ultimately a venue's choice whether to host such events, we hope it's helpful in explaining why there are concerns, and illustrating the life-threatening risks to patients that exposure to such health fictions pose. Here's date / venues

Self-described healer Barbara O'Neill is banned from giving health advice in her native Australia, but is booked for lucrative events in UK & Ireland next month. Health misinformation kills: we've written to venues elucidating why O'Neill's health fictions harm vulnerable patients ⏬

But, EVEN if these tests were done.. those epigenetic clock testing systems don't tell your biological age. In fact, they often disagree with each other by UP TO 17 BLOODY YEARS. Aging researchers don't even agree on them, so the entire exercise is at best pointless, especially as they ALREADY sell

..well firstly, these mysterious trials have never been done, nor are they to my knowledge even registered. With normal pharma products, you'd have to do a trial BEFORE you sell a product, but in the topsy-turvy world of supplements, you sell first and maybe ask questions later. Maybe!

So in all the promotion of this supplement, the claim it actually reverses aging and that there's clinical trial data to show this features heavily in the media blitz. Like this puff piece from the SBP... where it apparent shaves 5.2 years off your biological age. Where do I sign up?! Except...

Hard-right love "Ireland being overrun" narrative on immigration. But as @fotoole13.bsky.social notes, actual numbers small: here's log-plot of raw inward migration [2024-2025] in terms of Croke Park. As @csoireland.bsky.social explain, net immigration falling too.. t.co/lxq09kU7XU

So @jamesheathers.bsky.social & I answer the burning question: does Cake cause Herpes? No, but one can torture the data to give that impression, and that's a problem.

One response it is just a human interest story, but this doesn't negate responsibility of @theguardian.com to check things. As I wrote in The Irrational Ape, Andrew Wakefield's mendacious linking of autism to MMR vaccine only got traction in UK media due to such irresponsible credulity!

The piece has these red-flags without any scepticism. For instance, unhappy with NHS, author sought 2nd opinion from a doctor whose work is presented in glowing terms. Doesn't mention potential vested interest that same doctor charges £399 for online consultations on (fringe) CLD

Donald Trump talking garbage on public health. Incidentally, notorious fraudster Andrew Wakefield also proposed breaking up the MMR into separate vaccines because he had patents on an alternative but like Trump he was feeding into "vaccine overload" myth..

Provocateurs always insist they just want to debate things, because debate gives dubious positions a platform & even veneer of respectability. The reality is that debate too often rewards the most mendacious & leaves us all more divided (too long for tweet, text below🔻) (1/2)

Despite what the NYT seem to think, there's no evidence we were mislead about origins of COVID, & #lableak narratives remain unevidenced, underwhelming conjecture - but the abuse of scientists is very real, as I write in @irishtimes.com today: www.irishtimes.com/opinion/2025...
