Lettuce

Lettuce was first cultivated by the ancient Egyptians. At first, Lettuce was used to produce oils from its seeds, however, after a few centuries, the Egyptians grew romaine lettuce for its leaves. This new lettuce type had a shorter stem, broader leaves, and a more appealing taste, which transformed lettuce into food for consumption.

The types of lettuce include iceberg, which has a “large, firm head”; Batavia, which is “smaller and softer” than the iceberg lettuce; Romaine, which has long leaves with a “loaf-shaped head” and is the most popular in the US; and Butterhead, which has small, soft, oily leaves.
