Creatine's Brain Benefits Are Real, Small, and Suspiciously Dependent on You Being Tired or Old

Walk down the gluten-free aisle of any supermarket and you'll find pasta, bread, and crackers marketed to people who've never been diagnosed with celiac disease. They're not wrong…

One-third of American adults take a multivitamin, and roughly a quarter of kids and teens do too, according to the NIH Office of Dietary Supplements. That's not a niche habit. It's…

Walk into any pharmacy and the melatonin aisle has grown year over year, yet the single most-cited piece of evidence against it is a meta-analysis old enough to vote. Published in…

Somewhere between the salmon-oil capsules at CVS and the "ask your doctor" fine print sits one of the most persistent health beliefs in America: that omega-3 fatty acids protect yo…

I've covered this ground three times now. Each time, the evidence has pointed in the same direction: intermittent fasting produces results roughly comparable to calorie restriction…

Back in May, I wrote about how probiotics probably work — just not for you, specifically. The core argument was that strain specificity and individual microbiome variation make bla…

I've covered the coffee-heart story three times now — in May, in June, and in July — and each time the headline conclusion has been roughly the same: moderate coffee consumption ap…

I've now covered this territory three times — in July, again in late July, and here we are again. Each time, the story has been essentially the same: the observational data looks p…

I've covered intermittent fasting three times now (May, June, July), and the story has been stubbornly consistent: when you control for calories eaten, fasting's special metabolic…

I've now written about this topic twice before, and each time the honest conclusion has been the same: the observational evidence linking red meat to heart disease is real but mess…

For years, cardiologists were the people most likely to tell you to cut back on coffee. Arrhythmias, blood pressure, downstream stroke risk — the concerns were real enough that the…

I've covered this territory twice before — in June on bone health, and in July on respiratory infections specifically. The short version from that last piece: the evidence was cond…

I've covered this ground twice before — in May arguing that IF's "metabolic magic" was mostly calorie reduction in disguise, and in June when a new wave of trials still couldn't de…

When I last wrote about this topic, the central argument was that the headline-level claim — "red meat causes heart disease" — was doing a lot of work that the underlying epidemiol…

A quick note before we start: this topic overlaps with my June 3rd issue on vitamin D and bone health. That post focused on fractures and skeletal outcomes. This one takes a differ…

A few weeks ago, I wrote about coffee timing and cardiovascular mortality — specifically, the finding that morning drinkers fare better than all-day drinkers. That piece focused on…

Back in May, I argued that intermittent fasting's metabolic "magic" is probably just eating less. A fresh wave of research has landed since then — including a BMJ network meta-anal…

Here's a question that should make you suspicious of every red meat headline you've ever read: when researchers find that people who eat more red meat have higher rates of heart di…

For decades, the advice was so routine it barely registered as advice. Older adult? Take your calcium and vitamin D. Keep your bones strong. Stay on your feet. It was the kind of r…
