Albacore tuna is specifically Thunnus alalunga; bonita tuna and skipjack tuna are different species. A 100‐g portion, canned, is a rich source of protein, niacin, and vitamins B12 and D; a source of iodine. When canned in oil and drained it contains about 9 g of fat, of which 20% is saturated and 30% mono‐unsaturated; supplies 200 kcal (840 kJ). When canned in brine the fish contains little fat and the portion supplies 100 kcal (420 kJ).
