Health advice with a bibliography.

The internet is full of confident health claims. Almost none of them come with a citation, and the ones that do usually link to a single mouse study or a supplement company's blog.

Pure Watson is the opposite. Every claim here is traced back to the actual literature — and weighted by how strong that literature is. A randomised controlled trial in humans counts. A breathless headline about one observational study does not.

No miracle protocols, no products to sell. Just what the evidence currently supports about living longer and better — and, just as often, what it doesn't.
