What common attribute contributes to both Chocos and standard Corn Flakes falling short of a truly healthy breakfast standard?

Lack of sufficient fiber and protein

A breakfast cereal deemed truly healthy is expected to provide adequate levels of fiber and protein, which are crucial for stabilizing blood sugar patterns and ensuring satiety until lunchtime. Both Chocos and standard Corn Flakes generally fail to meet this requirement when compared side-by-side with options like muesli or porridge. The low fiber in Corn Flakes is explicitly noted, and processed, sweetened cereals like Chocos typically do not prioritize high fiber content either, resulting in a meal that does not provide lasting fullness.
