When UK government advice changed

From BSE and baby sleeping positions to face masks and fruit juice, official advice in the UK has sometimes changed course. This archive puts the before and after side by side, with links to the original records.

Every case is fact-checked. Some changes are fully documented. Others turn out to be weaker than the popular story, and we say so.
