Frosties Vs. Corn Flakes (Which is Best?)

Frosties and Corn Flakes are pretty similar-looking cereals, but it’s no secret that Frosties are covered with a sugary coating making Corn Flakes feel like the more sensible choice.

But is this really the case, and is there any difference between the two when it comes to nutrition?

In this article, I’ll be comparing Kellogg’s brand Frosties and Corn Flakes against each other to find out if one is better than the other in various categories, from nutrition to cost.

For information, this article relates to UK brand information; if you’re in the USA, click here to see the USA version comparing Frosted Flakes and Corn Flakes.

Ingredients Comparision

When you compare the ingredients of Kellogg’s Frosties against Corn Flakes Ingredients, they look the same, but what we don’t know at this stage is how much of each ingredient is used for each cereal.

Frosties and Corn Flakes are both made from maize, sugar, barley malt extract, salt, and the addition of vitamins and minerals to provide the consumer with a certain percentage of their daily value of each nutrient.

Because the recommended serving size of Frosties is 35g, whereas a serving size of Corn Flakes is 30g, we need to compare on a weight-for-weight basis to get an accurate and fair comparison.

I have included a comparison per 100g weight of each product and included a serving comparison for information only.
