Some spinach facts you might not know
Folklore doesn't have much to say about spinach. There aren't any historical myths, fairy tales, or recorded uses for this vegetable. However, like other leafy vegetables, spinach was traditionally sown on days when the moon is in Pisces, Scorpio, or Cancer in order to guarantee an abundant production of lush green leaves.
According to the USDA, the Northeast and the West consume the most fresh spinach, while the South eats the most canned spinach.

Types of spinach
1. Savoy spinach has dark green, wrinkled, curly leaves. This is the type sold in bunches in grocery stores in the United States.
2. Flat or smooth-leaf spinach has broad, smooth leaves that are easier to clean than savoy.
3. Semi-savoy is a hybrid variety with slightly crinkled leaves.

Myth vs. fact
In 1870, Erich von Wolf, a German chemist, decided to analyze the amount of iron found in spinach as well as a number of other vegetable greens, such as collards and kale. When recording his findings, he accidentally misplaced a decimal point, changing the iron content in his results by an entire order of magnitude. While there are approximately 3.5 milligrams of iron in one cup of spinach, the erroneous amount of 35 milligrams per serving became the accepted fact.
Once the incorrect number was printed, spinach’s nutritional value became legendary. When Popeye was created, the executives at Paramount Studios recommended he eat spinach for strength because of its highly acclaimed health benefits. Popeye's endorsement increased American spinach consumption by approximately one-third.
The error was corrected in 1937 after someone rechecked the numbers. But by that time, it had become a widely accepted fact.. The error was so widespread that in 1981, the British Medical Journal made the decision to publish an article discussing the erroneous spinach report in order to debunk the issue once and for all.
