2. Popeye Helps America Survive the Great Depression

Everyone knows Popeye’s secret. Whenever the cartoon sailor is on the verge of losing a fight, he squeezes open a can of spinach, pours the greens down his throat, and uses his supercharged muscles to pummel opponents. But fewer people know that the U.S. government is directly responsible for his dependence on canned vegetables.

In the 1930s, America was mired in the Great Depression, and the government was looking for a way to promote iron-rich spinach as a meat substitute. To help spread the word, they hired one of America’s favorite celebrities, Popeye the Sailor Man. It was a smart plan. In all of the comic strips to that point, Popeye’s superhuman strength had never been explained. But with the government’s campaign in place, Popeye was suddenly more than willing to share the secret to his strength. Sure enough, soon after Popeye took up spinach, American sales of the mighty veggie increased by one-third. Better still, American children rated it their third favorite food, right after turkey and ice cream.

But it wasn’t just spinach the government was endorsing. They were also pushing the merits of canned food. U.S. officials wanted Americans to know that cans were the perfect way to stock up on emergency rations.

While Popeye should be applauded for persuading a nation to eat its greens, he did mislead people a bit. The government’s enthusiasm for spinach was based in part on the calculations of German scientist Dr. E von Wolf, who’d discovered in 1870 that spinach contains iron. When calculating the results, he misplaced a decimal point, thereby making it “official” that spinach had 10 times more iron than it actually did. Not until years later were these figures rechecked. But by then, everyone was downing their spinach, hoping to be as tough as Popeye.
