Energy comes from USDA nutrient 1008. Salt is calculated as sodium × 2.5, with unit conversion to grams. It is not a separately measured salt value.
Preparation
Unsalted peanut butter is 598 kcal per 100 g, the same as the salted row to the calorie — salt has no energy, and removing it changes the sodium and nothing else. It is worth saying plainly, because unsalted and natural versions are often shelved as the lighter option and priced accordingly. If the jar is also unsweetened and unhydrogenated, that is a fat-quality difference, still not a calorie one.
Logging this food
Two tablespoons is 32 g and 191 kcal; a cup is 258 g and 1,543. Unsalted natural butters separate more than salted ones, so stir the jar before weighing or the first spoonfuls are oil and the last are paste. The scale settles it either way, and a spoon does not.
Swaps and alternatives
The salted row is the same 598 kcal per 100 g. Whole peanuts are 567 and slower to eat. If the reason for buying unsalted is blood pressure, this is the right jar; if it is calories, it changes nothing at all, and the portion is the only thing that will.
