Peanut Butter: Spoonfuls and Labels

How many calories are in a spoonful?

A weighed 15 g portion of chunky peanut butter supplies 88 kcal and 3.61 g protein. At 32 g, it supplies 188 kcal. A heaped spoon holds more, so weighing your usual spoonful once can be more practical than repeatedly guessing its weight.

Does crunchy mean sugar-free?

No. Crunchy and smooth describe texture. This salted reference contains 8.41 g total sugars and 486 mg sodium per 100 g. A 15 g serving contributes about 1.26 g total sugars and 72.9 mg sodium. Total sugars cannot all be labelled added sugars.

Peanut-only, unsalted and reduced-fat jars have different formulations. Read the ingredients first, then compare protein, fat and salt on the same 100 g basis. Texture alone does not establish that one product is healthier or higher in protein.

For a branded chunky option such as Fitnut Extra Crunchy, check the current jar separately; the historical figures on that page are not a verified panel for a new pack.

Counting the spread on bread

Even a thin layer contributes: the 15 g reference contains 7.49 g fat. Bread, banana or honey added alongside needs to be included separately. Logging the spread does not also log the bread underneath it.
