Tuna is a saltwater fish belonging to the mackerel family, and is one of the most consumed fish species. There are many different species of tuna, and they’re usually found in temperate and subtropical waters. Tuna is listed as an endangered species and numbers are decreasing in some parts of the world – especially in Japan and Australia – due to over-fishing.
Once you know the health benefits of tuna, it’s easy to see why it’s such a popular choice. Tuna is capable of reducing cardiovascular issues, lowering blood pressure and cholesterol levels, boosting the immune system, increasing energy, maintaining healthy skin, reducing inflammation, aiding weight loss, increasing red blood cell count, and protecting against various kidney diseases.
Tuna doesn’t contain much saturated fat or sodium, and is an ideal replacement for fattier meats like beef. They are an impressive source of many vitamins like vitamin B12, niacin, and riboflavin, and are full of other nutrients and minerals like selenium, phosphorous, iron, magnesium, and potassium.
Tuna can aid sleep because it is rich in vitamin B6, which is essential in making melatonin, that all-important sleep hormone. Tuna is a delicious, cheap and easy addition to your diet. You can include it in a salad, on a sandwich, in a casserole, with pasta, or straight from the can.
