According to a new study by the Environmental Working Group (EWG), a child who eats a bowl of kids cereal a day consumes 10 pounds of sugar in a year. The researchers analyzed 1,550 cereals, including more than 180 that are specifically for children. Here are the five national cereal brands with the most sugar: Kellogg's Honey Smacks Malt-O-Meal Golden Puffs Post Golden Crisp Kellogg's Apple Jacks with Marshmallows Kellogg's Froot Loops with Marshmallows Here are the six national cereal brands with the least sugar: Kellogg's Rice Krispies, Gluten-Free General Mills Cheerios Post 123 Sesame Street, C Is For Cereal Kellogg's Corn Flakes Kellogg's Rice Krispies Kellogg's Crispex Cereal EWG also analyzed again 84 popular children's cereals it had studied in 2011, and found that none of the cereal's on that years "worst" list had lowered their sugar content.
