Calories in Peanut Butter (Ireland)

Peanut Butter ranked by protein density

Showing the top 50 of the 61 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.

What the peanut butter numbers show

Median across all 61 of them is 4.1g of protein per 100 calories. Exactly one clears 10g of protein per 100 calories, which is the line Keith uses for a food that pays for its calories.

Calories run from 164 to 653 per 100g inside this one group, a 4-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 4.4g of protein per 100 calories across 31 products, against 2.7g for the 30 name-brand ones.

What to actually pick

Most of what is sold as peanut butter is not a protein food. Exactly one product clears 10g per 100 calories, and it sits at the top of the table — an exception, not a rule to shop by.

44 of the 61 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.
