About Tuna in salt water
Tuna in salt water is a preserved form of tuna fish that has been canned with added salt and water. Tuna is a popular seafood staple, originating from global coastal regions, and is especially important in Mediterranean, Asian, and American cuisines. This variety typically comes in chunks or flakes. Nutritionally, tuna is an excellent source of lean protein, omega-3 fatty acids, selenium, and B vitamins, while being relatively low in calories and fat. A 3-ounce serving provides approximately 20 grams of protein, less than 1 gram of fat, and substantial amounts of vitamin B12 and niacin, making it a nutrient-dense option for a healthy diet. The added salt increases sodium content, so portion control is ideal.
Health Benefits
- Supports heart health due to omega-3 fatty acids, which help reduce triglycerides and inflammation.
- Promotes energy production with vitamin B12, which plays a key role in red blood cell formation and DNA synthesis.
- Strengthens the immune system and offers antioxidant protection from selenium, a trace mineral abundant in tuna.
Dietary Considerations
