Tuna is a popular and versatile fish known for its high protein content and health benefits, including omega-3 fatty acids. However, the macro breakdown is not a one-size-fits-all answer. For a 10 oz portion, the specific calories, protein, carbs, and fat can vary drastically based on whether you choose canned or fresh, and which species you select. Understanding these differences is crucial for anyone tracking their nutritional intake.
Canned Tuna: Water vs. Oil
Canned tuna is a convenient and affordable way to get a significant amount of protein. But, the liquid it's packed in makes a huge difference in the final macronutrient count. Canned tuna packed in water is a champion of lean protein, while oil-packed varieties will naturally contain more fat and calories.
10 oz Canned Tuna in Water (Drained)
For a 10 oz serving of light canned tuna in water, drained, the macros are exceptionally lean.
- Calories: ~244 calories
- Protein: ~55g
- Fat: ~3g
- Carbohydrates: 0g
This makes it an ideal option for those looking to maximize protein intake without adding significant fat or calories. It's a staple for bodybuilders, athletes, and anyone on a low-fat diet. It also provides important micronutrients such as selenium and vitamin B12.
10 oz Canned Tuna in Oil
When tuna is packed in oil, the fat and calorie count increases. While the specific macros depend on the type of oil used and how well the tuna is drained, the general trend is more fat. A 10 oz serving of canned tuna in oil could contain significantly more fat, sometimes adding 20+ grams, depending on the brand and how it's prepared. The oil adds extra calories but can also enhance flavor and provide beneficial fats.
Fresh Tuna: A Species-by-Species Look
Fresh tuna offers a different flavor profile and texture, with macros varying by species. The fat content is the primary differentiator, with some species being much fattier than others.
10 oz Raw Yellowfin Tuna
Yellowfin tuna, a popular choice for steaks and sushi, is relatively lean. A 10 oz boneless, raw portion provides:
- Calories: ~309 calories
- Protein: ~69g
- Fat: ~1g
- Carbohydrates: 0g
This species offers even more protein per gram than canned light tuna, with very minimal fat, making it an excellent choice for a low-fat, high-protein meal. Yellowfin also contains beneficial vitamins and minerals, including a high dose of B6.
10 oz Raw Bluefin Tuna
Known for its rich, fatty flavor, bluefin tuna has a significantly different macronutrient profile. This fattier fish is a delicacy and is often used in high-end sushi and sashimi. A 10 oz raw portion contains:
- Calories: ~408 calories
- Protein: ~66g
- Fat: ~14g
- Carbohydrates: 0g
The higher fat content contributes to its calorie count but also means it's a great source of omega-3 fatty acids, with about 4g per 10 oz.
10 oz Raw Skipjack Tuna
Skipjack is another common type of tuna, often used in canned products. A 10 oz raw portion is also a lean protein source, with macros close to canned light tuna:
- Calories: ~292 calories
- Protein: ~62g
- Fat: ~3g
- Carbohydrates: 0g
It provides a great balance of high protein and low fat, making it a good choice for various dietary needs.
Comparison Table: Canned vs. Raw 10 oz Tuna
| Tuna Type | Calories | Protein | Fat | Carbs |
|---|---|---|---|---|
| Canned in Water | ~244 kcal | ~55g | ~3g | 0g |
| Raw Yellowfin | ~309 kcal | ~69g | ~1g | 0g |
| Raw Skipjack | ~292 kcal | ~62g | ~3g | 0g |
| Raw Bluefin | ~408 kcal | ~66g | ~14g | 0g |
Beyond the Macros: Other Nutritional Highlights
Beyond just the macros, tuna offers a wealth of micronutrients important for overall health.
- Omega-3 Fatty Acids: Particularly rich in EPA and DHA, tuna supports heart health and brain function. Fattier species like bluefin have higher concentrations.
- Selenium: Tuna is an excellent source of this antioxidant mineral, which is vital for thyroid function and protecting against cellular damage.
- B Vitamins: High in Vitamin B12 and Niacin, tuna helps with energy metabolism and neurological function.
- Potassium: An important electrolyte that helps regulate blood pressure. Yellowfin and skipjack are particularly good sources.
Key Factors Influencing Tuna Macros
Understanding what impacts tuna's nutritional values is essential for making informed dietary choices.
- Preparation Method: The biggest factor is how it's prepared. Canning, especially in oil, adds calories and fat that fresh tuna does not have. The liquid used for canning significantly alters the final macro profile. For example, canned tuna in oil contains more calories and fat than canned tuna in water, and if the oil isn't fully drained, those numbers will be even higher.
- Tuna Species: The type of tuna itself dictates its inherent fat content. Bluefin tuna is naturally fattier than yellowfin or skipjack, which is reflected in its higher calorie and fat macros. Choosing a species depends on your specific dietary goals, such as prioritizing a leaner protein source or consuming more beneficial fats.
- Serving Size: While our focus is on 10 oz, it's always important to remember that all nutritional information scales with the serving size. A smaller 4 oz portion will have a proportional decrease in all macros and calories.

Conclusion
To answer the question, "What are the macros for 10 oz of tuna?", you must first clarify the type and preparation. Canned light tuna packed in water provides a remarkably lean and high-protein option, with approximately 55g protein, 3g fat, and 0g carbs per 10 oz. In contrast, fresh bluefin offers a similar amount of protein but with a higher fat and calorie count due to its natural composition. For those seeking leanest protein, canned in water or fresh yellowfin are top choices, while bluefin offers more omega-3s for a fat-inclusive diet. Ultimately, knowing the specifics of your tuna helps you make the best choice for your dietary needs. Healthline's article on canned tuna.
