You don't have a vitamin D deficiency. No one does. At least, that's according to the Endocrine Society guidelines. My new piece:

My new piece is on cocoa supplements and why chocolate probably isn't going to stop you aging. https://t.co/DUZW8tU27g

Please follow and bookmark to see me and my guests Dr. Gideon Meyerowitz-Katz (@GidMK), Dr. Tyler Black (@tylerblack32) and Adam Zivo (@ZivoAdam) as we have a nuanced conversation from across the political divide on the evidence and politics around pediatric gender affirming care

New piece looks at remarkably bad research integrity cases on hugely impactful studies where the journals took years to respond. This is bad, it's an ongoing problem, no one is trying to fix it. https://t.co/zZkUdwK4S2

My new piece looks at headlines saying that peanuts are the key to longevity and why it's just bad science. Wherein I get to unironically use the term Big Nut. https://t.co/Ai1tvZq34L

I've never written about pandemic origins, because as someone with no stake in the discussion I never really cared one way or the other. But since people being disastrously wrong, here's my opinion about why COVID-19 was almost certainly not a lab leak

There have been some incredibly misleading headlines about metformin for older women's longevity recently. Turns out they are based on some very meagre data. My new piece: https://t.co/xqCXrvTUYc

My new piece looks at recent headlines, and why oats probably aren't helpful when it comes to PFAS in your body. https://t.co/IaPnwYVMxd

Recent headlines have been fearmongering about pesticides in tampons. Turns out, the data shows that there is nothing to worry about. The amount of glyphosate (not a pesticide) in tampons was actually vanishingly low. https://t.co/R9ZrThje9q

Biden has prostate cancer. Should you get a test? Maybe. The data is very mixed, and for men his age screening is not even recommended without symptoms. https://t.co/FRFt0Y9feb

Measles is an incredibly infectious disease. Even minor dips in vaccination rates can cause big outbreaks. I wrote about why this is, and why I'd expect the U.S. measles epidemic to continue to grow. https://t.co/DJc3EziwjB

Measles Is Dangerous https://t.co/hdhYrrdjg9 by @GidMK The long-disproven myth the MMR vaccine causes autism "used to be popular mostly in the bizarre corners of the internet." But "it has become mainstream due to RFK Jr. & the current U.S. government endorsing it."

Two children are dead in Texas from measles. Here's why, as an expert in the topic matter, I make sure my daughter gets her vaccines on time. Measles is a dangerous disease. https://t.co/BbfrSaezGm

A common MAHA claim is that diabetes rates are skyrocketing, with the blame usually on food additives or dietary guidelines. But it's not really true. In fact, it's provably true to say that diabetes rates have been falling in the U.S. for over a decade. https://t.co/3tiUW6HX31

No, despite recent headlines, coffee is probably not giving people heart attacks. If anything, the opposite is more likely. https://t.co/92R75lVq0F

Vitamin A supplements are not a replacement for vaccines when it comes to measles (and for American kids may not help at all). This is not a contentious fact. https://t.co/XRQ3WQcmb7

"...no reason to believe that vaccines are destroying anyone’s immune system. The new study is scientifically inadequate, and cannot possibly tell us anything about health issues related to vaccination." COVID Vaccines Aren’t Causing AIDS https://t.co/dgqNjpDR3W by @GidMK

There's been a lot of noise recently about the idea that COVID-19 vaccines are causing immune damage. Some rather woeful commentators have even used the term AIDS. My new piece explains why this is gibberish based on bad science. https://t.co/7kq4nh01Xo

INSPECT-SR is a massive Delphi consensus study, I've never met or corresponded with most of the 37 other authors. Specifically, I've met 4 of them online, 4 in person, and have published with 5 of them to some extent.
