Oysters are seen by many as a food for the rich and famous. It certainly hasn't always been the case and need not be now. The Romans had a passion for Oysters (well they did for most food didn't they) and it was they who began cultivating them in Colchester. Their reputation grew so much that they were transported even back to Rome.
The majority of Oysters are eaten raw and are often associated with love and romance. It is possible that this is down to how good they are for you and more specifically the high amount of zinc they contain.
There are three types of Oysters cultivated and eaten in Britain: the native or European oyster; the Pacific oyster; and the Portuguese or rock oyster.
The beds on which these bivalves are cultivated are often in shallow estuaries and they have in the past suffered from pollution with over-industrialisation.
In recent years the cleanliness of our coastal waters have improved significantly and with that Oyster farming is doing well.
