Michael Jackson, black and white, get it? Grass jelly sitting in soya milk. It sounds healthy because soya, but the soya milk at most stalls is sweetened heavily and the cincau is soaked in sugar syrup. So you are drinking maybe 30 grams of sugar in a glass.
It is not the worst choice lah, at least you get a bit of protein from the soya, around 6 grams. But do not kid yourself that it is a health drink. Ask for the unsweetened soya version if they have it and you cut a big chunk of the calories straight away.
