Also, keep in mind that alien proteins that are completely innocuous in their biology might be very toxic to humans. Even among earth species, there are animals that eat things that kill others quite quickly.
Humans are very omnivorous however (We eat things that make most animals go blind), so I am sure that at some point someone will try anyways.
