In this nutritional comparison, I’ll be comparing Kellogg’s brand Frosties against Kellogg’s brand Corn Flakes.
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.
