What the porridge & oats numbers show

442 of the 443 porridge & oats products carry 20 calories or more per 100g, which is the floor below which protein per 100 calories stops being a real number. Across those the median is 3g of protein per 100 calories. 4 clear 10g of protein per 100 calories — about one in 110, and 10g is the line Keith uses for a food that pays for its calories.

Calories run from 25 to 501 per 100g inside this one group, a 20-fold spread, so “porridge & oats” 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 3.3g of protein per 100 calories across 52 products, against 3g for the 390 name-brand ones.

What to actually pick

Most of what is sold as porridge & oats is not a protein food. The 4 that clear 10g per 100 calories sit at the top of the table and are the exceptions, not the rule.

67 of the 442 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 calorie app.

FAQ

How many porridge & oats products are in this database?

We track 443 porridge & oats products across Irish supermarkets and brands. 442 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.

What's the most protein-dense porridge & oats product?

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 3g per 100 calories and 4 products clear 10g — that tells you whether porridge & oats is worth buying for protein at all, which protein per 100g does not.
