What Surprising Ingredient Was Once Considered Poisonous in Food History?

One of the most surprising twists in food history involves the tomato, which was once widely regarded as poisonous. Originally native to South America, tomatoes were introduced to Europe in the 16th century, but their adoption was met with skepticism. The plant belongs to the nightshade family, which includes many toxic species, leading to fears that tomatoes were harmful. In fact, aristocrats often avoided them, believing that eating tomatoes could lead to illness or even death. It wasn't until the 18th century that tomatoes began to gain popularity, particularly in Italy, where they became an essential ingredient in dishes like pasta and pizza. Today, the tomato is celebrated worldwide, forming the basis of countless cuisines and culinary traditions, showcasing how perceptions of food can drastically change over time.
