Frosties Vs. Corn Flakes Nutritional Comparison
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.
