Why Kefir (plain, low-fat) shows up in protein-forward diets
Nutritionally close to milk with a marginally higher protein count, but the actual reason people choose kefir over milk is the live bacterial culture count, not the protein.
Serving-size math
A 1 cup (240ml) portion delivers 9.1g of protein and roughly 98 calories. Scaled per 100 calories, that works out to 9.27g of protein — useful for comparing against other foods on a calorie-matched basis rather than a weight-matched one.
Prep tip
Shake before pouring — kefir separates more than milk and the top layer alone isn't representative.
