The medieval Catholic Church banned eating of meat on religious days, and in C7 the number of such days was dramatically expanded. The fast for Lent was increased to 40 days, and Fridays, the day of Christ's crucifixion, were included. In all, nearly half the days of the year became 'lean' days, and the laws were strictly enforced. Under English law the penalty for eating meat on Friday was hanging. On lean days sex was forbidden, and you were only allowed one meal. Red meat was out bc it was "hot" and so associated with sex. But meat from water creatures was ok bc it was "cold", so beavers, porpoises and whales acceptable.
