Live Yogurt - Good for You!
These bacteria feed on sugars and produce acid which in turn produces an environment in which it is difficult for other, more harmful, bacteria to live.
To be effective the yogurt should be eaten in fairly large quantities and every day.
When the bacteria reach your stomach the acid there kills a lot of them. But the ones that survive have been proved to be very beneficial in many ways.
The problem is that live yogurt tends to be expensive.
The solution? Make your own! Just buy one container of plain live yogurt. Mix a few teaspoonfulls of it into some fresh milk or soya milk in a clean sealed container. Place that in a warm (not hot) place for a few hours until it sets. The top of the fridge is a great place usually that keeps it at just about blood temperature. Then as soon as it has solidified, refridgerate it.
