🚨NEW PUBLICATION!🚨 We reviewed virtually every major claim behind the seed oil hysteria, and the evidence doesn’t support the fear. The controversy is largely social media-driven, built on ecological correlations, mechanistic speculation, and flawed trials...

Fun finding: two studies on ostensibly the same research question using the same dataset published in the same journal a few months apart that find the opposite results (Fibre being associated with higher odds of endometriosis in one and lower odds in the other)

We've got ISSUES. Literally. We scraped >100k special issues & over 1 million articles to bring you a PISS-poor paper. We quantify just how many excess papers are published by guest editors abusing special issues to boost their CVs. How bad is it & what can we do? arxiv.org/abs/2601.07563 A 🧵 1/n

Interesting finding: A rather odd meta-analysis in which not a single study meets their inclusion criteria, and nearly 100% of the data presented is incorrect. I have genuinely no idea how the heck you could end up with this (AI hallucinations? Something else?) pubpeer.com/publications...

Remember that cruciferous vegetables and cancer study I wrote about recently? Turns out it's even more borked than I said. Some excellent sleuthing here, the study probably needs to be retracted or extensively corrected.

Hey @gidmk.bsky.social, following this post, I dug into the study further, and it turns out there are a *lot* more issues with it. Only one of the estimates used is actually what they claim it is (odds ratio for the association between highest vs lowest intake of cruciferous veg and colon cancer)..

Academic gut-health microbiome research has not really led to efficacious treatments for specific ailments that can be demonstrated in rigorous studies. But they *have* convinced the public that gut health is somehow, vaguely at the root of all illness, and food companies have profited off this.

Elon Musk casually, and illegally, dismantled USAID. According to a new study in the Lancet, that action will lead to *14 million* premature deaths between 2025 and 2030. Again: Elon Musk is directly responsible for 14 million coming deaths. 4.5 million will be children.

Having read the full MAHA report, what stands out the most to me, as an epidemiologist, is how inexplicably sloppy it is. The US government collects data on every health condition you can think of, and the report doesn’t use any of it.

Oh, it's already happened: A large Norwegian city wrote a report on school closures which cited a slew of AI-hallucinated papers - and this op-ed praised the AI for "pointing to spaces of knowledge", as a way to "inspire and invite the [future] papers we need". www.nordnorskdebatt.no/tromso-feile...

Fortunate to contribute to this edition of @annualreviews.bsky.social and the timing couldn't be more serendipitous as nutrition is at the forefront of many folks' minds and there is active conversations about what future Dietary Guidelines should look like. www.annualreviews.org/content/jour...

As soon as RFK Jr was appointed, it was only a matter of time before Wakefield 2.0 was offered a role in the Trump administration. But still, it is shocking to see.

Thanks to everybody who chimed in! I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist. So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

My prediction: once vaccines are “proven” to cause autism, the people in the “autism registry” will begin receiving information about “better ways to manage autism.” RFK Jr has made clear he’s not pursuing socialized medicine because he thinks the free market is a better option for health care. 🧵

"We'll just terraform Mars," they insist, unable to terraform Earth, a planet that is already perfect except it's like 2° too warm.

The anti-vaccine crowd say they just want to “see the evidence” in the form of placebo-controlled randomized trials. But we've done these trials. And we know our vaccines work. Which is precisely why we can't use placebo to test better vaccines. Read more: epiellie.substack.com/p/first-do-n...

After 21 years at my dream job, I’m very sad to announce my early retirement from the National Institutes of Health. My life’s work has been to scientifically study how our food environment affects what we eat, and how what we eat affects our physiology.

If you're keeping track of the long list of things this admin's done that flies in the face of MAHA, censoring and ultimately losing the top intramural nutrition scientist studying food processing and health is definitely towards the top.

I've never seen a ton of bricks come down so hard on a study. In it, keto enthusiasts test their theory that very high LDL isn't as risky in lean, metabolically healthy people on keto diets as it is in others. The test: plaque progression in that cohort. www.sciencedirect.com/science/arti...

This is from a published randomized trial with 138 citations.
