Where It Grows
Tuna, being a type of fish, does not grow in the typical sense of cultivation but rather lives and thrives in various oceanic environments. They are predominantly found in the Atlantic Ocean, Pacific Ocean, and Mediterranean Sea. The largest species of tuna, the Atlantic bluefin, is common in the western and eastern Atlantic Ocean as well as the Mediterranean Sea. Major tuna fishing nations include Japan, the United States, and Spain. Tuna prefer warm waters, and are often found in the open ocean, rather than close to shore.
Best Way to Eat
Tuna can be eaten in a variety of ways and is a versatile ingredient in many dishes. It can be eaten raw as in sushi or sashimi, which are popular preparations in Japanese cuisine. This method retains the full nutritional benefits of the fish. Tuna can also be grilled or baked, often marinated beforehand to enhance its flavor. It's important to cook tuna properly to avoid overcooking and drying it out. Tuna is also commonly canned, providing a convenient option that retains much of the nutritional value. Regardless of the preparation method, consuming tuna with a source of vitamin C can enhance the body’s ability to absorb the iron present in this fish.
