Copy-paste from Wikipedia (although I heard it before a couple of times):
“Popeye the Sailor Man has a strong affinity for spinach, becoming physically stronger after consuming it. This is partially due to the iron content being mistakenly reported ten times the actual value, a value that was rechecked during the 1930s, where it was revealed that the original German scientist, Dr. E von Wolf, had misplaced a decimal point in his calculations. In truth, spinach actually has about the same iron content as a lot of other vegetables, and even less than others. Cooked broccoli and cauliflower, for example, have almost double the iron content of spinach.”
