On the container of my yogurt that I eat in the mornings, it says, "Contains live cultures including acidophilus and bifidus." I'm sure I can look that up and get a scientific explanation somewhere, but I'm not very scientifically inclined... can someone tell me what that means in layman's terms? I'm assuming it's good for you, but what does it do, exactly?
Also, "live" cultures... does that mean there's something living in the yogurt?
Pardon my ignorance, by the way.
