There is a story, which may be apocryphal, that in the late 16th century Sir Walter Raleigh brought potatoes into the gardens and court of Queen Elizabeth.

Once they'd grown and were harvested, the cooks having no familiarity with the plant, promptly discarded the tubers, and instead used the stalks & leaves in various dishes.

As a result, at a banquet featuring this wonderful new plant, everyone was violently ill, resulting in the potato being banned from the court.
