When I was a little kid, I would wake up early in the morning before school and watch cartoons. I remember watching, among other things, George of the Jungle and Popeye.
Popeye, of course, was the sailor who had a romantic interest in Olive Oyl. Unfortunately for Popeye, so did his archnemesis Bluto (later known as Brutus), a burly, bearded brute who liked to give Popeye trouble. But there was never any real concern that Bluto would win the day. All Popeye had to do was gulp down a can of spinach, and with his bulging muscles, pound Bluto into oblivion.
Spinach, in other words, was among America's first superfoods. Alas, science shows that "superfoods" aren't real.
