Key Nutritional Benefits of Tuna
Protein Powerhouse
Tuna is an excellent source of protein, which is crucial for building and repairing tissues, supporting immune function, and promoting overall health. Including tuna in your diet can contribute significantly to your daily protein intake.
Omega-3 Fatty Acids
Tuna is a good source of omega-3 fatty acids, particularly DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). These essential fats are known for their numerous health benefits, including supporting brain health, reducing inflammation, and promoting heart health (5, 6).

Vitamins and Minerals
Besides protein and omega-3s, tuna provides various essential vitamins and minerals. It is a good source of vitamin D, which is vital for bone health and immune function. Tuna also contains selenium, an antioxidant that helps protect against cell damage, and iodine, which is necessary for thyroid function (1, 2, 3).
Considerations for Choosing Tuna
- Canned in Oil vs. Water: As shown in the table, canned tuna packed in oil tends to be higher in calories and fat compared to tuna packed in water. If you are watching your calorie or fat intake, opt for water-packed tuna.
- Sodium Content: Canned tuna generally has a higher sodium content than fresh tuna. If you are sodium-sensitive, check the label and choose low-sodium options or rinse the tuna before consuming it.
