From http://en.wikipedia.org/wiki/Yoghurt :
"The Russian Nobel laureate biologist Ilya Ilyich Mechnikov, from the Institut Pasteur in Paris, was influenced by Grigorov's work and hypothesised that regular consumption of yoghurt was responsible for the unusually long lifespans of Bulgarian peasants."
I know it's entirely my choice whether to be eclectic versus 100% paleo but maybe someone can provide an argument. I thought yogurt was one of those foods that was unanimously thought of as healthy (until I found out about paleo the other day).
