What is Spinach Good For?
Obscurely referred to for years as “the Spanish vegetable” in England, the name of this leafy green was later shortened to what we call it today.1 Spinach cultivation is thought to have originated from ancient Persia, later spreading to Nepal, and by the seventh century, to China, where it’s still called “Persian Greens.” The Moors introduced it to Spain around the 11th century.2
According to the United States Department of Agriculture (USDA), Americans consume nearly 2 1/2 pounds of spinach per year, per capita. This easily quadruples the amount eaten 40 years ago,3 possibly because of a drastic overhaul in image and presentation.
Now greener, tastier and crisper by freezing, fresh spinach is often used for salads and in place of lettuce on sandwiches.
No other vegetable has ever gained the fame that spinach did in the 193 0s through the cartoon character Popeye.4 Parents often encouraged their children to eat their spinach so they would grow up to be big and strong like the cartoon sailor, and there’s actually some truth to this claim.

Studies Done on Spinach
Because of the potentially high incidence of Dichlorodiphenyltri chloroethane (DDT) contamination, be sure to buy only organic varieties of spinach as much as possible. A known cause of cancer, birth defects and reproductive damage,13 DDT has been banned in the U.S. since 1972,14 but it may still be manufactured and exported to other countries, where it’s most often used to fight mosquito-borne malaria.15
What’s worse, DDT can stay in soil for years. In fact, spinaches grown in the soils that have been sprayed with DDT before 1972 are this pesticide, according to a report by the USDA. 16,17
