About Tuna fish
Tuna fish, a saltwater species belonging to the mackerel family, is a staple in many cuisines worldwide, particularly in Mediterranean, Japanese, and Pacific Island diets. Known for its rich, meaty flavor, tuna is often served raw in sushi and sashimi, grilled as a steak, or canned for convenience. Nutritionally, tuna is a lean protein powerhouse, offering approximately 25-30 grams of protein and only about 1 gram of fat per 3-ounce serving. It is an excellent source of omega-3 fatty acids, B-vitamins (especially B12 and niacin), vitamin D, and key minerals such as selenium, magnesium, and phosphorus. Tuna is also low in carbohydrates, making it suitable for low-carb diets.
