Well the article does not provide any source to its claims, does not even attempt to prove anything, yet you accept USA today repeating something as a proof that "beer was a safe alternative to water". Is it even as established fact that water was unsafe to drink ? if so where ? when ? Unsafe water in large overcrowded cities such 19th century London is proven but an exception not the general situation for the whole world over time.
