Let'stalkaboutthedietinEurope500yearsago.Oneimportantfoodwasmeat.Europeansatemanykindsofmeat,includingbeef,lamb,goat,andpork.Europeansalsoatedairyproducts,milkandcheesemadefromthemilkofcowsandgoats.TheEuropeansateseveraldifferentgrains:Mostpeopleatewheat,andsomepeopleaterice,whichcamefirstfromAsia.
