Protein needs plateau at 1.6 g/kg/day (Morton et al., Br J Sports Med 2018). Per 100 g dried: 339 kcal, 11.7 g protein, 968 mg sodium. Whey is a by-product of cheese-making — mostly sugar with some protein.
How should I track Whey, acid, dried?
Whey, acid, dried is high in calcium. The best way to track Whey, acid, dried 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.
