Some children's breakfast cereals are more than 50 percent sugar, according to research from Consumer Reports.
Of the 11 brands Consumer Reports looked at, Post Golden Crisp made by Kraft Foods and Kellogg's Honey Smacks are more than 50 percent sugar by weight, containing about as much sugar as a glazed doughnut.
The nine other brands tested contained at least 40 percent sugar, Reuters reported.
Consumer Reports named Cheerios with three grams of fiber per serving and just one gram of sugar, to be one of the healthiest cereals aimed at kids. General Mills' Kix and Honey Nut Cheerios, as well as Life cereal, made by PepsiCo Inc's Quaker Oats unit, were also deemed healthy.
Honey Smacks contains 15 grams of sugar and just one gram of fiber per serving. Kellogg's Corn Pops has 12 grams of sugar and no fiber, according to the report.
