If you’re looking for a versatile, nutrient-packed protein source, tuna deserves a spot on your plate. It’s rich in lean protein, omega-3 fatty acids, and essential vitamins like B12 and D, making it a favorite among health-conscious eaters.
Whether you’re fueling up after a workout or aiming for a balanced meal, tuna’s combination of quality protein and heart-healthy fats is ideal.
Plus, it’s incredibly convenient since tuna is available with plenty of options to suit your preferences, such as:
Fresh
Frozen
Canned
Today, we’re bringing you 3 high-protein tuna recipes that are nutritious and easy to make at home. From light salads to satisfying mains, these recipes prove that healthy eating doesn’t have to be complicated.
Is Tuna Very High In Protein?
Yes, tuna is very high in protein, making it a fantastic choice for those looking to boost their protein intake.
A 3-ounce serving of canned tuna (in water): around 20 grams of protein (1)
3-ounce serving of fresh, cooked tuna: around 25 grams (2)
To give you some context, that’s similar to skinless chicken breast, which provides about 27 grams of protein per 3-ounce serving (3), and much more than a large egg, which has about 6 grams of protein (4).
What’s even better is that tuna is a complete protein.
In this context, “complete” means that tuna contains all 9 essential amino acids—nutrients our bodies do not naturally produce (5).
Beyond its impressive protein content, tuna is also a nutritional powerhouse.
It’s a rich source of omega-3 fatty acids, which support:
Heart health
Brain function
Inflammation reduction
Tuna is also low in fat and calories, making it an excellent option for those aiming to maintain or lose weight (7).
Mercury content is worth addressing, as it concerns many types of fish, including tuna (8).
While it’s perfectly safe for most people to enjoy tuna in moderation, pregnant women, nursing mothers, and young children should stick to lower-mercury options (9).
Following recommended portion guidelines (e.g., 2-3 servings of fish per week) ensures you get the health benefits of tuna without overexposing yourself to mercury.

What Is The Healthiest Thing To Eat With Tuna?
The healthiest way to eat tuna depends on your dietary goals, but generally, you should pair tuna with nutrient-dense, whole foods to create a balanced meal or snack.
Tuna is high in protein; balance it with complex carbohydrates and additional healthy fats.
Here are some of the healthiest tuna combo options:
1. Leafy Greens And Veggies
Why? They’re low in calories, high in fiber, and packed with vitamins and minerals.
Ideas:
Make a tuna salad with spinach, kale, arugula, cucumbers, tomatoes, and bell peppers.
Why? They’re rich in fiber, vitamins, and antioxidants, making them a tremendous, nutrient-dense carb.
Ideas: Serve tuna on a baked sweet potato or mix it into a sweet potato hash
6. Greek Yogurt
Why? It’s high in protein and probiotics, making it a lighter alternative to mayo.
Ideas: Use Greek yogurt to make a creamy tuna salad.
7. Nuts And Seeds
Why? They add healthy fats, crunch, and extra nutrients like omega-3s.
Ideas: Sprinkle sunflower seeds or chopped almonds on a tuna salad
8. Zoodles Or Veggie Noodles
Why? They’re a low-carb, nutrient-rich alternative to pasta (much more satisfying than a tuna and water diet)
Ideas: Toss tuna with zucchini noodles, olive oil, and cherry tomatoes for one of the best high-protein tuna recipes low carb-style
Is Tuna Good For Building Muscle?
When it comes to building muscle, you can’t overlook the importance of protein.
Tuna is a protein powerhouse, offering around 20 grams of protein per 3-ounce serving of canned tuna in water (1) and 25 grams in fresh, cooked tuna (2).
What makes tuna even better is its status as a complete protein.
It contains all nine essential amino acids—your body’s must-have building blocks for repairing and rebuilding muscle after training.
The Power Of Leucine In Tuna
A standout amino acid in tuna is leucine, a key player in muscle building.
Leucine can trigger muscle protein synthesis, the process your body uses to repair and grow muscle tissue after a workout (13). Some scientific studies have suggested that foods high in leucine may be particularly effective in supporting muscle recovery and growth, making tuna an ideal choice for your post-workout meals (14).
Omega-3 Fatty Acids For Muscle Recovery
Beyond protein, tuna delivers a hefty dose of omega-3 fatty acids.
These healthy fats have anti-inflammatory properties, which help reduce muscle soreness and speed up recovery after hard training sessions.
Omega-3s may also optimize muscle cells, making them work more efficiently (15).
If you’re serious about staying consistent in your workouts, the omega-3s in tuna might make a noticeable difference.
Low In Calories, High In Nutrients
Building muscle doesn’t necessarily mean overeating, especially if your goal is lean muscle. Tuna is also relatively low in calories, which is especially useful if you’re trying to find high-protein tuna recipes for weight loss or building lean muscle without gaining excess body fat.
Compared to other protein sources, such as beef or pork, tuna provides a similar amount of protein with fewer calories and less saturated fat.
A 3-ounce serving of canned tuna in water provides about 20 grams of protein (1), while the same portion of skinless chicken breast delivers roughly 27 grams (3).
While chicken edges out slightly in protein content, the difference is minor, and both are great options to include in a high-protein diet.
Fat And Calorie Differences
Tuna tends to be lower in calories than chicken, especially if it’s canned tuna in water rather than oil.
A 3-ounce portion of tuna has about 109 calories (1), while chicken breast contains around 133 calories for the same serving size (3). Again, there is no significant difference, so we can consider them comparable.
Regarding fat composition, chicken breast is very low in fat, providing just 3 grams per serving, and it is primarily unsaturated.
Depending on the variety, tuna is also low in fat but supplies heart-healthy omega-3 fatty acids, which chicken lacks. These omega-3s are essential fats that promote brain health, support heart function, and may help reduce inflammation (17, 18, 19).

Nutritional Profile
Tuna is rich in omega-3 fatty acids, vitamin D (helpful for bone health), and selenium, a powerful antioxidant (7).
Chicken is an excellent source of B vitamins, such as B6 and niacin (20), essential for energy metabolism, brain health, and healthy skin (21).
Both foods are nutrient-dense, but tuna stands out for its omega-3 content, while chicken is a better source of several B vitamins.
Health Considerations
While tuna has clear perks, it does come with the consideration of mercury content. Larger fish like tuna can accumulate higher levels of mercury, which can be harmful in excessive amounts. To manage risk, opt for canned light tuna, which has a lower mercury content than albacore or yellowfin, and limit tuna intake to 2–3 servings per week (22). If you are pregnant, breastfeeding, or feeding young children, talk to your doctor for specific recommendations.
Chicken, on the other hand, is free of mercury concerns.
However, some processed chicken products, such as cured sausages or deli meats, can be high in sodium or contain preservatives. For health-conscious meals, choosing fresh, minimally processed chicken breast is best.
Versatility And Practicality
Chicken can be a more versatile protein option due to its mild flavor and adaptability in various cuisines.
It’s not about which is “better”—tuna and chicken can be nutritious additions to a balanced diet.
Tuna shines when you want a low-fat protein option with the added benefit of omega-3 fatty acids. Chicken takes the lead for a more flexible protein, richer in B vitamins, and free from mercury concerns.
Choosing between chicken or tuna depends on your:
Nutritional goals
Taste preferences
How they fit into your weekly meal plan.
By balancing both in your diet, you can enjoy both benefits.
Eating tuna every day is not generally recommended due to its mercury content.
While tuna is an excellent source of lean protein, omega-3 fatty acids, and essential nutrients, it can also contain varying levels of mercury, which can be harmful if consumed in excess over time.
Higher Mercury Tuna: Albacore (white) tuna and bigeye tuna have higher mercury levels.
Lower Mercury Tuna: Skipjack (light) and canned light tuna are lower in mercury and safer for more frequent consumption.
The Food and Drug Administration (FDA) suggests limiting albacore tuna to 1 serving (6 ounces) per week. For light tuna, you can safely eat 2-3 servings (12-18 ounces) per week (22).
While it’s safe to have tuna a few times a week, it’s best to:
Refrain from eating tuna daily
Vary your protein sources for a well-rounded diet.
If you’re concerned about mercury levels, opt for other lean protein options like chicken, turkey, tofu, or lentils on alternate days. Additionally, purchasing sustainably sourced tuna can help reduce environmental impacts and potential contaminants (23).
Pregnant or breastfeeding women, young children, and individuals sensitive to mercury may need to limit their tuna consumption more strictly (22).
Talk to your doctor for specific recommendations.
