Peanut Butter ranked by protein density

Showing the top 50 of the 198 peanut 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 peanut butter numbers show

Median across all 198 of them is 4g of protein per 100 calories. 14 clear 10g of protein per 100 calories — about one in 14, and 10g is the line Keith uses for a food that pays for its calories.

Calories run from 70 to 690 per 100g inside this one group, a 10-fold spread, so “peanut 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 4.3g of protein per 100 calories across 23 products, against 4g for the 175 name-brand ones.

What to actually pick

Most of what is sold as peanut butter is not a protein food. The 14 that clear 10g per 100 calories sit at the top of the table and are the exceptions, not the rule.

111 of the 198 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.
