It is wondered what these ancient people ate for protein as each civilization had its own diet for meat.
When it came to hunting, men hunted game in marshes near the oasis in the desert. Hunting was a leisure activity for the wealthy and the poorer civilians benefited as they got some extra food. Poorer Egyptians did eat meat but only special occasions that were part of festivals. Wealthy classes did eat meat since ducks, geese, pigs, cattle, and antelope were domesticated.
As the climate they lived in was hot any meat had to either be eaten immediately or preserved by salting, drying, smoking or adding honey beer and every once in a while fish roe.
