Tuna canned in water is one of the leanest, most convenient protein sources in the pantry, with about 19 g of protein and only 1 g of fat per 100 g once drained. Oil-packed tuna carries noticeably more calories, even after draining. The biggest additions usually come later, from mayonnaise in tuna salad or sandwiches, so measure it or swap in yogurt.
