Salted butter carries 583 mg sodium per 100 g (He et al., BMJ 2013). Per 100 g: 731 kcal, 78.3 g fat. Even small amounts used in cooking contribute sodium to the total meal.
How should I track Butter, whipped, with salt?
The best way to track Butter, whipped, with salt is by weight, not volume. A 200 g serving of yogurt or cheese varies in density between brands and fat levels, so the same portion can differ by 20–40 calories. Research shows people underestimate calorie-dense dairy portions by up to 50% when eyeballing (Almiron-Roig et al., Appetite 2013). A kitchen scale keeps things honest. Also check whether the label lists values for the product as sold or as prepared — some powdered or concentrated dairy products show very different numbers once mixed.
