Fine in a portion — worth keeping an eye on.
A single cup of Frosted Flakes carries about 12 g of added sugar, before milk adds its own natural lactose on top. At 37 g per 100 g, over a third of the cereal itself is sugar coating.
Compare that to plain oatmeal at around 1 g per bowl, or even sweetened granola at a similar 12 g. The difference is that cereal bowls are rarely measured to a single cup — a normal breakfast portion of 1.5–2 cups can put away 20 g of sugar before the day starts.
Lower-sugar swaps
- Plain oatmeal or unsweetened cereal topped with fruit for natural sweetness
- Mix half a sugary cereal with half a plain one to cut the total in half
Frequently asked questions
- How does Frosted Flakes compare to plain cereal?
- Much higher. Plain cornflakes or oats have very little sugar; the frosting coating on Frosted Flakes adds about 12 g per cup on its own.
- Is granola better than sugary cereal?
- Not always — many granolas carry a similar sugar load per serving. The real fix for both is checking the label and measuring the bowl you actually pour.
