The article says "Yogurt...is a kind of fermented milk produced by cows. ... Yogurt is a key part of the diet in places such as Mongolia (where it is made from goat or yak milk)."
Would anybody mind if the first sentence just said "Yogurt...is a kind of fermented milk."? The bit about "produced by cows" is falsified by the later mention of goats and yaks. And the milk is what is produced by cows, not the yogurt. PaulBurnett 23:04, 6 June 2009 (EDT)
