Yet another frustrating anecdote about trying to correct the scientific record academic.oup.com/jrssig/artic...

"These findings suggest that longstanding concerns regarding publication bias in CAM publishing have not diminished over time and appear to have intensified..." Reports of positive outcomes have ~doubled, while reports of negative findings remain ~nonexistent. pubmed.ncbi.nlm.nih.gov/42249414/

Yet another spurious non-linear Mendelian randomization paper has been retracted by a journal academic.oup.com/jpubhealth/a... Kudos to the editors of the Journal of Public Health for following through and retracting spurious publications. What is shocking is that many other journals /cont

A huge point about meta-analysis, which begs for reliance on individual patient-level data and adjusting for a full set of covariates.

This!

Meta-analyses in nutrition may pool estimates for completely incomparable effects without realising it, just because of whether/how energy intake is adjusted. @nataliaortega.bsky.social will explain why, share results from a meta-scientific review & offer recommendations for ways forward 👇

Nonsense functional medicine stuff needs WAY more pushback from health professionals. We needed pushback several administrations ago, and now we are here.

In a rationale country, the fact that a surgeon general candidate made any money from selling supplements, let alone $325K in 2 years, should be disqualifying.

I launched version 3.0 of my browser extension "Lazy Scholar", a free in-browser research assistant. It opens automatically when you load an academic article. See: lazyscholar.org/2026/01/10/l...

Sad to see these revised standards for 'integrative and functional nutrition' coming from RDs in the era of MAHA - a time to critically evaluate, not endorse, this psuedoscientific gish gallop of unvalidated diagnostic tests & handwavey rationale for therapy (mitochondria! toxins! epigenetics!)

Gave some quotes to the @nytimes.com in this piece covering saturated fat in some anticipation of potential rollbacks on these regulations from the Kennedy HHS/Rollins USDA Dietary Guidelines. It's a meaty topic but Dr Callahan covered it well for the general public!

No, glucose monitors aren't particularly helpful for people who don't have diabetes or pre-diabetes. Pathologizing insulin spikes is yet another distraction from the reality of an untenable food environment. www.washingtonpost.com/food/2025/09...

My new piece is on the painfully slow process of scientific error-correction and how it harms real people all the time. Also, why cinnamon probably isn't a useful treatment for diabetes. gidmk.substack.com/p/cinnamon-f...

A new expression of concern was published on this randomized clinical trial of cinnamon for diabetes. The study itself has been cited, according to Google, 1,700 times. I first complained about it in 2023, so let me tell you the story of one of the most problematic papers I've come across 1/n

An army of medical contrarians and wellness quacks to take over our health systems. What could go wrong.

"If one group weaponizes retractions to delegitimize studies they find problematic, why shouldn’t another?" Our Ivan Oransky speaks with Alice Dreger of Heterodox Academy

Investigating fraud and errors in health research is obviously laudable. But we need to maintain high methodological standards. That means scrutinising each others’ work, and calling each other out when we err. There are so many errors in error detection. A few recurring errors:

National Science Foundation "is planning to lay off between a quarter and a half of its staff in the next two months," Politico reports. www.politico.com/news/2025/02...

We shared code and outputs on GitHub, but a journal told us: "GitHub unfortunately does not meet our data sharing requirements. Please revert to using the OSF, or a similar suitable repository." ... what??

At least AI will be able to easily fetch us all these absurd AI claims in 5 to 10 years so we can laugh about them.

We've had a paper reviewed by ERROR, which has concluded we had a "major error that affects a core conclusion" Few comments on the conclusion and the process in general 1/n

"We’d urge publishers that have yet to adopt this approach to embrace transparency. The scientific record should reflect what actually happened, not a sanitised narrative that leaves out the messy bits." Amen.

Opened a systematic review of 'RCTs' on creatine and memory, checked the study with the largest reported effect size, and it is clearly not randomized. 🙄

Cool and rare opportunity
