Canned Tuna calories & macros
116 calories per 100 g · 99 calories per 3 oz (85 g). Canned Tuna (canned in water, drained).
Canned tuna in water is one of the leanest, cheapest proteins available: 100 g delivers about 25 grams of protein for only 116 calories and almost no fat. That makes it a go-to for anyone chasing a high-protein, low-calorie day. Tuna packed in oil carries far more calories, and water-packed is the pick when you are counting.
