I just came back from Tesco's and decided to drink the YOP drink that I purchased there.
For anyone who doesn't know, it's a yoghurt drink that comes in loads of flavours.
Anyway... looking at the bottle, I start to read:
* source of calcium
* low in fat
* no preservatives
* with live cultures
* suitable for vegetarians
* no artificial sweeteners
but what the hell is "with live cultures"???
