Ingredients Comparision

Starting with the ingredients comparison, you might be surprised to know that Corn Flakes and Frosted Flakes contain exactly the same ingredients, although we don’t know at this stage how much. For example, both kinds of cereal contain sugar, but does one have more than the other?

Corn Flakes and Frosted Flakes are both corn-based cereals that are made from milled corn as the main ingredient.

Both kinds of cereal are also fortified with the same added vitamins and minerals, although the amounts may differ (which I’ll compare later in this article).

Cereal TypeIngredientsVitamins and Minerals
Kellogg’s Corn FlakesMilled corn, sugar, malt flavor, contains 2% or less of salt.Iron (ferric phosphate), niacinamide, vitamin b6 (pyridoxine hydrochloride), vitamin b2 (riboflavin), vitamin b1 (thiamin hydrochloride), folic acid, vitamin d3. Vitamin b12.
Kellogg’s Frosted FlakesMilled corn, sugar, malt flavor, contains 2% or less of salt.Iron (ferric phosphate), niacinamide, vitamin b6 (pyridoxine hydrochloride), vitamin b2 (riboflavin), vitamin b1 (thiamin hydrochloride), folic acid, vitamin d3, vitamin b12.

A recommended serving of Corn Flakes is 42g, whereas the recommended serving of Frosted Flakes is 37g, which means the servings aren’t equal. So, I’ve calculated nutrition based on a weight of 100g per cereal and also included the serving values for information.

The comparisons are based on Kellogg’s Brand Corn Flakes and Frosted Flakes, and you can see the data references at the bottom of this page.

Overall Winner

Each category has been compared, and it’s time to reveal a winner of which is best for nutrition and price between Kellogg’s Corn Flakes and Frosted Flakes, and the winner is – Corn Flakes.

Corn Flakes came out on top for being the lowest in sugar and carbs while being higher in protein and vitamins and minerals.

While although Frosted Flakes contain slightly fewer calories, they are much higher in sugar, so calories are kept lower in other areas to make them look healthier than they actually are.
