The Olympic Games (of course) Pisa Olympia The inhabitants of Pisa founded the Olympic games in 776 BC & organised them until 572 BC. Pisum derives from Pisa where archaeological remains show that peas were cultivated by the ancient Greeks Sherwood (1898) Garden Peas J.RHS 22: 239-260
Three things I am going to say Food legumes are diverse, with useful nutritional properties Food composition can be controlled genetically This means we can define the genetics of nutritional properties and use this to create or identify functional foods.
