The tomato was considered poisonous by many Europeans for 200 years after its introduction from the Americas. Wealthy families who ate tomatoes on pewter plates sometimes died, as the tomato's acid leached lead from the pewter. Once people understood this connection, and began using different plates, tomatoes became a staple of European cuisine.
