Frequently asked questions
Are Frosted Flakes just Corn Flakes with sugar?
Essentially yes. Frosted Flakes start from the same extruded corn base and add a sugar coating, roughly 12g of added sugar per serving. That coating is the main processing difference between the two.
Which cereal is less processed?
Corn Flakes scores lower in our analysis thanks to its shorter ingredient list. Both are extruded, fortified cereals, so neither is minimally processed; plain oats are a common less-processed swap.
