Movie Popcorn Has Shocking Amount Of Calories Fat In It

CBS reports on a study by the Center for Science and Public Interest that analyzed nutritional makeup iof movie popcorn; the results are eye-opening. Consuming a medium size popcorn and soda is the equivalent of eating three Quarter Pounders from McDonald's, along with 12 pats of butter.

The caloric and fat content of this theater staple will have you thinking twice before you order:

the concessions from Regal, the country's biggest movie chain, have 1,160 calories and three days worth - 60 grams - of fat. Regal said that the medium popcorn had 720 calories and the large had 960, but CSPI's tests found those numbers to be understated. A small popcorn at Regal had 670 calories - the same as a Pizza Hut Personal Pepperoni Pan Pizza. Even if you share a small popcorn - it's still about a day's worth of saturated fat per person, according to CSPI.

In related news, a study sponsored by the United Health Foundation, Partnership for Prevention, and American Public Health Association found that 40 percent of the U.S. will be obese by 2018: "the states most in danger of a ballooning obesity epidemic are: Kentucky, Maryland, Mississippi, Ohio, Oklahoma and South Dakota."
