Cereals remained the most important staple during the early Middle Ages. Barley, oats and rye were eaten by the poor. Standard foods included bread, porridge, and gruel. Fava beans and vegetables were important supplements to the cereal-based diet of the lower orders. Meat was expensive and prestigious. Game was common only on the tables of landowners. The most prevalent butcher's meats were pork, chicken, and other domestic fowl; beef, which required greater investment in land, was less common. Cod and herring were mainstays among the northern populations; dried, cooked or salted, they made their way far inland, but a wide variety of other saltwater and freshwater fish was also eaten.[11]
