Why is the consumption of tuna advantageous?
Tuna belongs to the family of predatory fish known as mackerels. There are many species of it, such as Bluefin, Bonito, or Albacore. Over the course of a year, it travels thousands of kilometers and migrates over very long distances. It has a high nutritional value for the fish. It contains many health-promoting compounds that have a positive impact on the human body. Tuna is rich in vitamins and minerals, but also in protein and, most importantly, healthy fats. The polyunsaturated fatty acids present in it have a range of positive effects, such as reducing the risk of certain types of cancer, such as colon and pancreatic cancer (J. Zalega, D. Szostak-Węgierek 2013), as well as cardiovascular diseases (M. Kołodziejczyk, Ł. Bułdak, B. Okopień 2021). The European Food Safety Authority (EFSA) does not recommend eating tuna during pregnancy. The same applies to swordfish and marlin. This is due to the presence of significant amounts of heavy metals, especially mercury, in some fish, particularly long-lived predatory fish, which can enter the fetus and cause developmental disorders (J. Alexander et al. 2004). It is also worth noting that tuna should not be consumed more than 2 times a week.

There exist several of its variants, such as in oil, in its own sauce, or in tomato sauce. Herein, we present several recommendations for the utilization of tuna.
