Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of
spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach.
Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many
people's diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does
not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a
mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that
spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted
it.
Today, we know that the little iron there is in spinach cannot make a difference in how strong a person
is.However, spinach does have something else which the body needs-folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic
acid that made Popeye strong all along.
