Look, Americans might not always make the healthiest eating choices.  But at least we know not to leave work at noon and scarf down a dozen DONUTS.

--A market research company called Scarborough surveyed adults on fast food lunches.  More than three-quarters of people ate fast food for lunch in the past month . . . but only 2% went to Dunkin' Donuts, making it the least popular spot.

--McDonald's was the most popular . . . 43% of Americans ate lunch at McDonald's in the past 30 days.  Even Americans who consider themselves "health conscious" eat lunch there . . . 36% of them had McDonald's for lunch in the past month.

--The rest of the 10 most popular fast food lunch spots are:  Subway, Wendy's, Burger King, Taco Bell, Chick-fil-A, Arby's, KFC, Panera Bread, and Pizza Hut.

--On the other end, Dunkin' Donuts is the least popular, just below Papa John's, White Castle, Church's Chicken, and Long John Silver's.
