Calories in Breakfast Cereal (Ireland)

Breakfast Cereal ranked by protein density

Showing the top 50 of the 346 breakfast cereal products that carry a comparable calorie figure, ranked by protein per 100 calories. Figures per label, sourced from Open Food Facts and tracker user logs.

What the breakfast cereal numbers show

Median across all 346 of them is 2.4g of protein per 100 calories. Not one of them clears 10g of protein per 100 calories, which is the line Keith uses for a food that pays for its calories.

Calories run from 70 to 519 per 100g inside this one group, a 7-fold spread, so “breakfast cereal” on its own tells you almost nothing about what a portion costs you.

Name brands do lead this one: 2.4g of protein per 100 calories at the median across 310 products, against 2g for the 36 own-label ones.

What to actually pick

Nothing here is a protein food, so treat it as calories. At a median of 2.4g of protein per 100 calories this group is a taste and energy decision, not a macro one.

67 of the 346 carry 400 calories or more per 100g — the ones worth weighing rather than eyeballing.

Where this fits

The practical half of this — counting calories without weighing everything.

For one specific product rather than the whole group, the 20,000-product database is searchable on Calories in Ireland, and the same figures are built into the free calorie tracker.
