Kellogg's Frosted Flakes: 11g added sugar per 1 cup (41g). Sugar Tier E.

Short answer: Frosted Flakes Kellogg's Frosted Flakes contains 11g of added sugar per 1 cup (41g) — about 44% of a child’s daily 25 g American Heart Association added-sugar limit. Tier E in our Sugar Tier System.

The verdict

Frosted Flakes deliver 11g of added sugar per serving — about 44% of a child's daily 25g AHA allowance in one bowl. The base is a plain corn flake, but the "frosting" is a sugar coating that is the second ingredient by weight. The CDC's NHANES data flags sweetened breakfast cereal as the single largest source of added sugar in the American 2–8 year-old diet, and Frosted Flakes is a textbook example. Tier E — closer to dessert than breakfast.
