A claim with no receipts is a rumour with good lighting.

This is the list of receipts I ask for, in the order I ask. Was it tested in humans. Who exactly was studied. Compared to what. How big was the effect, in absolute numbers. For how long. Who paid. Most claims fall over by question four.

Every question comes with a real case: the aspirin trial with no women in it, the knee operation that did no better than a pretend one, the pill warning that was accurate and still did harm. Each case names its paper, so you can read it yourself. Each question ends with the phrase that usually means someone is selling.

Then fifteen of those phrases, translated. Then all twelve questions on one page, for the fridge.

It won't tell you what to eat or take. Not once. It will make you harder to fool.
