A full cup has 12 g of added sugar, just over the 10 g per-meal ceiling in the 2025–2030 Dietary Guidelines; a ¾-cup bowl has 9 g. The 190 mg of sodium is about 13% of the under-1,500 mg daily limit for ages 4–8. Dry cereal is not on the AAP or CDC choking lists.
Swaps and pairings
With 2 g of protein and 1 g of fiber, a cup is under the FDA's 10% Daily Value marks (5 g protein, 2.8 g fiber). With ¾ cup of skim milk, Kellogg's lists 8 g of protein. Fruit adds fiber. Plain corn flakes cereals are also sold; compare the "Includes Xg Added Sugars" line.

Kellogg's sells chocolate and other versions, and store brands sell frosted corn flakes under their own names. Their labels differ; the numbers here are for the original Kellogg's cereal only.
