Butter ranked by protein density

Showing the top 50 of the 172 butter 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.

What the butter numbers show

Median across all 172 of them is 0.1g of protein per 100 calories. 2 clear 10g of protein per 100 calories — about one in 86, and 10g is the line Keith uses for a food that pays for its calories.

Calories run from 36 to 774 per 100g inside this one group, a 22-fold spread, so “butter” 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 0.1g of protein per 100 calories across 44 products, against 0.1g for the 128 name-brand ones.

What to actually pick

Most of what is sold as butter is not a protein food. The 2 that clear 10g per 100 calories sit at the top of the table and are the exceptions, not the rule.

129 of the 172 carry 400 calories or more per 100g — the ones worth weighing rather than eyeballing.

Where this fits

Front-of-pack claims on this stuff rarely match the back, so scan it with the label checker.

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.
