But that doesn't mean your kids can pig out on Halloween candy. We've got candy eating tips from a doctor and a dentist and the Top 5 most fattening candies.
There are a lot of little folks doing dress rehearsals for the big day. And whether it's Spiderman or Mario's crew or Anakin Skywalker, they're all after one thing -- candy!
Trick or treating for candy is a part of growing up in America, and eating your loot is the reward.
"Just a few pieces is totally fine, but just remember if you have too much, you're not gonna have a hyped up child but you will have a bellyache," Kelsey-Seybold Pediatrician Dr. Jakeen Johnson said.
Candy is candy, and while there's no nutritional value to eating any of it, some candy is more fattening than others.
The most fattening candy based on calories, fat, sugar and carbs is Peanut M&M's. Just three of the fun-sized packages will cost you 220 calories and 28 grams of sugar! Second worst are Raisinets. They have 200 calories and 29 grams of sugar. Skittles come in third, with 180 calories and 33 grams of sugar. Fourth in place are Whoppers with 190 calories, 26 grams of sugar. And the fifth worst candy on this list is Milky Way, with 190 calories and 25 grams of sugar.
