A "Taboo" is a strong social prohibition (or ban) relating to any area of human activity or social custom that is sacred and or forbidden based on moral judgment, religious beliefs and or scientific consensus.
Some examples:
Taboo food:Cats, Dogs, Elephants, Camels, Whales, Primates and of course Human meat.

Taboo drinks:Blood and Human breast milk are common standard taboos...
But some religions can also ban drinks like: Alcohol, coffee and tea.

These were only small examples the lists are much longer and more detailed.
