A bowl of cereal alone shouldn’t give you or your kids the shakes first thing in the morning. But considering the amount of sugar in these breakfast favorites, don’t be too surprised if you start feeling a little rattled. Here are some of the least healthful breakfast cereals marketed directly to children according to the Rudd Center for Food Policy and Obesity at Yale University, which studied 277 different types of cereal and ranked them based on a variety of health factors. Don’t be surprised if they’re among your adult favorites too. (This might just change your grocery shopping habits.)

10. Froot Loops 
These colorful loops, not surprisingly, are among the least healthful breakfast cereals. Regular Froot Loops are 41 percent sugar and 10 percent fiber, plus red, blue and yellow dyes. But the Marshmallow version is even worse. They’re 48 percent sugar and 7 percent fiber.

9. Corn Pops 
Certain cereals are just as sugary as a glazed doughnut, according to Consumer Reports findings last year. “We studied how 91 youngsters, ages 6 to 16, poured their cereal and found that, on average, they served themselves about 50 percent to 65 percent more than the suggested serving size for three of the four tested cereals,” it said. Corn Pops are 41 percent sugar and have no fiber at all, according to Rudd Center studies.
