Showing the top 50 of the 437 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, last checked 2026-09-18.
Scan your own shop with FoodSussed: calories and macros from the barcode, plus an estimated processing level from 1 to 4 with the reasons. Or start with the fat-loss guide built around Irish food.
Median across all 437 of them is 2.5g of protein per 100 calories. 6 clear 10g of protein per 100 calories — about one in 73, and 10g is the line Keith uses for a food that pays for its calories.
Calories run from 44 to 545 per 100g inside this one group, a 12-fold spread, so “breakfast cereal” on its own tells you almost nothing about what a portion costs you.
Own-brand is not the compromise here. The supermarket own-label median is 2.5g of protein per 100 calories across 35 products, against 2.5g for the 402 name-brand ones.
Most of what is sold as breakfast cereal is not a protein food. The 6 that clear 10g per 100 calories sit at the top of the table and are the exceptions, not the rule.
101 of the 437 carry 400 calories or more per 100g — the ones worth weighing rather than eyeballing.
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 calorie app.
Real barcode-matched products with a confirmed photo — the same rule as Calories in Ireland: a photo only shows where we have a confirmed Open Food Facts match, never a guessed stock image.
We track 437 breakfast cereal products across Irish supermarkets and brands. 437 of them carry 20 calories or more per 100g, which is the point below which protein per 100 calories stops being a real number, so those are the ones ranked and averaged here.
The table is sorted highest protein per 100 calories first, so the answer is the top row. The more useful number is that the median for the whole group is 2.5g per 100 calories and 6 products clear 10g — that tells you whether breakfast cereal is worth buying for protein at all, which protein per 100g does not.
