Eat to beat cystitis

Drink: Cranberry juice

Why: Substances called proantho-cyanidins in cranberries help prevent the E coli bacteria, which is responsible for most bladder infections as it sticks to the bladder wall. For protection against repeated bouts of cystitis, you need to have at least 300ml a day of a cranberry drink that contains around a quarter pure juice. A good choice is Ocean Spray Cranberry Classic, 95p for a litre, from supermarkets. But don’t go overboard – too much of this juice will stain your teeth.
