Question for milk, or non-milk people, to be exact. Would Kefir or yogurt (from cow milk) be considered as bad or unhealthy as regular milk? I'm not sure if the fermentation process does anything to improve it, besides add the extra bacteria.
I of course mean plain kefir/yogurt too. Once you add tons of sugar, it automatically becomes unhealthy. There are some relatively low-carb-ish yogurts out there, so the glucose load shouldn't be too bad. But I'm not sure about the milk element itself.
