If you had to name the greatest food in the history of mankind . . . and I gave you 50,000 guesses . . . you still wouldn't come up with this.

According to the economists behind the book and the website "Freakonomics", the greatest food in human history just might be . . . the McDonald's McDouble.

If you're somehow not familiar, the McDouble is two hamburger patties and a piece of cheese on a bun.  It costs $1 at pretty much every McDonald's in the country.  And that's part of why it's so great.

 

 

 

 

 

Putting aside your feelings on fast food, it's never been possible to get so many calories, so much protein, calcium, fiber, and a few vegetables for so cheap.  Supposedly the entire world could survive forever just eating McDoubles.

 

 

 

 

Each one has 390 calories, 50% of your daily protein, 20% of your daily calcium, and 7% of your daily fiber.

 

 

The runner-up pick for the best food in human history was . . . boiled lentils.
