Lettuce: The Greeks believed that lettuce was a sad and depressing food that would sap one’s youth and kill one, because of its connections with an old Greek myth. The belief was that one of Aphrodite’s lovers, Adonis, was killed on a lettuce field and Aphrodite forever cursed lettuce as a result. Currently lettuce is considered a very healthy vegetable and is featured in salads, sandwiches and multitudes of food.
