The bullet tuna or japuta has a meat of high nutritional value, with a very consistent and dark fat content that lightens considerably with culinary preparation. Indeed, it is a fatty fish, as its lipid content is 5g per 100g of edible portion. In addition, it has a high protein content, higher than many other fish. Among the trace elements, it provides selenium, phosphorus, potassium, and iodine. Regarding vitamins, vitamin B12 is once again the most abundant, with contents per average serving equivalent to six times the recommended daily intakes for this mineral (RDIs). In the bullet tuna, vitamin B12 is present in significant amounts that exceed those found in eggs and a large part of meats, animal-derived foods, which are a natural source of this vitamin. It is also a source of vitamin B6 and niacin. These three vitamins contribute to normal energy metabolism. Among the fat-soluble vitamins, it stands out for its content of vitamin D (maintenance of normal bones and teeth) and vitamin E (protection of cells against oxidative damage). One serving of bullet tuna covers 128% of the recommended intakes of vitamin D for men and women aged 20 to 39 who engage in moderate physical activity.
