Beef up on your burger stats

Burgers are a thing of the past for me -- I stopped eating red meat a little more than a year ago, which struck burgers right from my diet. Turkey burgers never really did anything for me so a burger-free girl I am. Makes me think I'm in the minority when I stumbled upon this statistic in the June 2008 Redbook magazine: Americans eat 13 billion burgers per year. Now that's a lot of beef. Check out these other stats:

• The year a burger was first served on a bun: 1891

• Ounces of meat in a Wendy's "Where's the beef?" hamburger: 4

• The cost of a hamburger at White Castle when the chain first opened its doors in 1921: 5 cents

• Pounds gained by Super Size Me star Morgan Spurlock after eating McDonald's for one month: 25
