What Breakfast Cereals Have More Sugar Than Is Recommended Per Day?

While one serving of any cereal does not exceed the recommended daily sugar allowance on its own, many cereals offer half of the recommended sugar amount, including Kellogg's Honey Smacks. It tops the list of the most sugary cereals, with Froot Loops, Cap'n Crunch's Crunch Berries, Apple Jacks and Smorz close behind. Other cereals with an abundance of sugar are Honey Gram Oh's, Cap'n Crunch's Original, Cap'n Crunch Oops! All Berries, Froot Loops with Fruity Shaped Marshmallows and Golden Crisp.

Kellogg's Honey Smacks is comprised of 55.6 percent sugar. One cup of the cereal contains more sugar than a Hostess Twinkie, with 15 grams in a serving. Post Golden Crisp is 51.9 percent sugar, and Kellogg's Froot Loops with Marshmallows is 48.3 percent sugar. Quaker Oats Cap'n Crunch's All Berries is 46.9 percent sugar, while Cap'n Crunch's Original and Quaker Oats Oh's are comprised of 44.4 percent sugar.

The World Health Organization recommends that people consume no more than 5 percent of their calories from sugar. For an adult with normal body mass index, this equals approximately 25 grams, or 6 tablespoons, of sugar in a day. The American Heart Association follows similar guidelines by stating that the average male should consume 9 tablespoons of sugar at most each day and the average female should have no more than 6 tablespoons of sugar in a day.
