What Is the Most Common Vegetable in the World?

The vegetables that are grown in the largest quantities around the world are the tomato and the potato. But the most widely used vegetable is the onion.

The onion appears in more dishes and in more countries than any other vegetable. In some places, the onion is used to flavor dishes, while in other countries it’s eaten by itself as a vegetable.

The ancient Egyptians ate onions both ways, for the onion was the most common vegetable in Egypt 5,000 years ago. During the Middle Ages, the onion and a relative of the onion, the leek, were the only common vegetables in Europe.

Today, more than 20 billion pounds of onions are produced around the world each year.

Emperor Nero of Rome ate leeks because he thought they would improve his singing voice.

  1. Funny you’re the one calling someone an idiot Jessie..

    Scientifically speaking, a tomato is definitely a fruit. True fruits are developed from the ovary in the base of the flower, and contain the SEEDS of the plant

    Tomatoes,Cucumbers,Squash and Peppers are ALL fruits, despite their savory or even spicy flavor.

    In MY opinion. The most commonly used vegetable is either the onion or the potato.

  2. Tomato is a vegetable. Just because something is a fruit, doesn’t mean that it’s not a vegetable. The two are not mutually exclusive. There is a scientific definition for fruit that tomato falls under- yes. But no such definition exists for vegetable, because “vegetable” is a culinary term, not a scientific one. Jessie never said that tomato is not a fruit. He merely claimed the obvious: that a tomato IS a vegetable. Which indeed it is. So learn your facts before you call someone an idiot, idiot.

  3. It I also worthy to note that all plants are vegetables under the botanical definition of a vegetable- since you wanna get all scientific. And since fruits are plants, and a tomato is a fruit, then that makes your precious tomato a vegetable too.

  4. Oh dear Jessie, get your facts straight before mouthing off. The idiot is correct – Tomato is a fruit not a vegetable :-)
