Popeye the Sailor Man(《大力水手》)first became a popular cartoon in the 1930s. The sailor in that cartoon ate lots of spinach(菠菜)to make himself strong. People watched him,and they began to buy and eat a lot more spinach. This cartoon helped sell 33% more spinach!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(铁)in spinach made the sailor strong,but it is not true. Spinach does not have any more iron than other green vegetables.

Earlier,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 other kinds of vegetables. The group made a mistake,but everyone accepted it.

Today,we know that spinach can't make a person very strong. However,spinach does have something else that the body needs—a vitamin called folic acid(叶酸)．
