(USA TODAY) Taco Bell's latest mantra: Protein matters.

It matters so much, apparently, to Taco Bell customers that the Mexican fast-food chain late Thursday announced that it's overhauling its entire Cantina platform and replacing it with bowls and burritos packed with at least 20 grams of protein that weigh in at 500 or fewer calories.

"People are not looking for diet food," said President Brian Niccol, in a conference call with reporters. "They want food that gives them energy."

(WXIA) -- Krispy Kreme is preparing for its 77th birthday. To celebrate, it is offering customers a special deal on its signature donut, the Original Glazed.

"Made from a recipe dating back to the 1930's, our uniquely delicious Original Glazed donuts help set Krispy Kreme apart from any other sweet treat retailer," Krispy Kreme chief marketing officer Dwayne Chambers said in a release.

On Friday, July 11, Krispy Kreme customers can buy a dozen Original Glazed donuts for only 77¢ with the purchase of another dozen donuts. The offer is available all day at participating restaurants.
