- Net carbs are total carbohydrate minus fiber: 79.5 g − 3.5 g = 76 g per 100 g. Low-carb plans usually count these.
- Protein per 100 kcal compares how much protein each food gives for the same calories: Corn Flakes gives 1.8 g.
- Energy density is calories per gram. At 3.65 kcal/g, Corn Flakes is medium on the CDC's scale (very low below 0.6, low to 1.5, medium to 4, high above 4); lower-density foods give a larger portion for the same calories.
Logging Corn Flakes: what to know
These are plain corn flakes, so frosted and honey-coated cereals will differ. A cup is 30 g, and a bowl poured by eye can hold more than one cup, so weigh the cereal before the milk goes on. Sodium is 703 mg in every 100 g, and milk is a separate entry.
