Foods high in acid, like tomatoes, would cause the lead to leech out into the food, resulting in lead poisoning and death. Poor people, who ate off of plates made of wood, did not have that problem, and hence did not have an aversion to tomatoes. This is essentially the reason why tomatoes were only eaten by poor people until the 1800’s. Most likely the first variety to reach Europe was yellow in color, since in spain and Italy they were known as pomid’oro, meaning yellow apples. Italy was the first to embrace and cultivate the tomato outside South America. The French referred to the tomato as pommes d’amour, or love apples, as they thought them to have stimulating aphrodisiacal properties.
