Were tomatoes ever thought to be poisonous?

Americans may be in love with tomatoes today, but the relationship got off to a rocky start. During Colonial Times, we wouldn’t put a tomato near our mouths, let alone try to eat one. Folklore had it that if you ate a tomato, its poison would turn your blood into acid. Instead, the colonists grew tomatoes purely for decoration.

In the late 1700s, a large percentage of Europeans feared the tomato.

A nickname for the fruit was the “poison apple” because it was thought that aristocrats got sick and died after eating them, but the truth of the matter was that wealthy Europeans used pewter plates, which were high in lead content. Because tomatoes are so high in acidity, when placed on this particular tableware, the fruit would leach lead from the plate, resulting in many deaths from lead poisoning. No one made this connection between plate and poison at the time; the tomato was picked as the culprit.
