## Articles

- [Does vitamin C stop you catching colds?](https://dr-schwartz.com/does-vitamin-c-stop-you-catching-colds.html): Decades of Cochrane trials find no meaningful drop in cold risk for ordinary adults, only a modest shortening of colds once they start.
- [How we weigh the evidence](https://dr-schwartz.com/how-we-weigh-the-evidence.html): Every claim we assess carries the same two marks: how strong the evidence is, and which way it points. This is the method behind them, and the reason we sometimes say "we don't know."
- [The evidence pyramid: why not all studies are equal](https://dr-schwartz.com/the-evidence-pyramid.html): "A study found" tells you almost nothing until you know what kind of study it was. A quick tour from anecdote to meta-analysis.
- [Relative vs absolute risk: the trick behind scary headlines](https://dr-schwartz.com/relative-versus-absolute-risk.html): "Doubles your risk" and "raises it from 1 in 10,000 to 2 in 10,000" can describe the exact same finding. One sells papers; the other tells you what to do.
- [What scientists mean by "consensus"](https://dr-schwartz.com/what-scientists-mean-by-consensus.html): A scientific consensus is not a vote, and not a demand for silence. It is what remains standing after decades of people trying to knock it down.
- [How a single study becomes a myth](https://dr-schwartz.com/how-a-single-study-becomes-a-myth.html): The pipeline from a modest finding to a confident health myth is short, well-worn, and easy to spot once you know the stations it passes through.
- [Does sugar make children hyperactive?](https://dr-schwartz.com/verdict-sugar-and-hyperactivity.html): It is one of the most confidently repeated claims in parenting. It is also one of the most thoroughly tested, and the tests do not support it.
- [Do you need eight glasses of water a day?](https://dr-schwartz.com/verdict-eight-glasses-of-water.html): The famous rule is everywhere. A clear scientific basis for it is not.
- [Where the evidence stands: physical activity](https://dr-schwartz.com/where-the-evidence-stands-physical-activity.html): On a subject where much is contested, this one is not: across an enormous body of research, regular movement is among the best-supported things you can do for your health.
