This is exactly what I'm talking about though, evolution was already proven long before the 1930s, and yet doctors went against an obvious evolutionary truth that breastmilk from a healthy, well-fed mother is superior to processed formula all because a few "studies" proved it?? (cough studies funded by formula companies cough)
Well I would tend to agree but I think in many cases the alternative wasn't mother's milk exactly but that of a wet nurse. Perhaps they thought this was a vector for infection.
