9 Nutritious Ways to Add Tuna to Your Diet

Looking for a quick, high-protein meal that doesn’t sacrifice nutrition? Tuna is one of the most versatile and affordable options you can keep in your kitchen. Whether you choose canned tuna or fresh tuna steak, this lean fish delivers impressive health benefits.

A 3-ounce serving of canned tuna in water provides about 16.5 grams of protein and just 73 calories, while tuna steak offers even more protein around 26 grams per 3 ounces. Tuna is also rich in omega-3 fatty acids, which support heart and brain health.

Here are nine of the healthiest ways to eat tuna without relying on heavy sauces or excess sodium.

1. Canned Tuna Grain Bowl

Turn canned tuna into a balanced, fiber-rich meal.

• Drain tuna and add it to cooked farro or quinoa.

• Mix in roasted vegetables like butternut squash, carrots, fennel, or broccoli.

• Add fresh herbs such as basil or chives.

• Top with tahini dressing and freshly ground pepper.

Because canned tuna can contain around 210 milligrams of sodium per serving, taste before adding extra salt.

2. Tuna and Cannellini Bean Salad

This Mediterranean-inspired combination is rich in both protein and fiber.

• Toss tuna and cannellini beans over arugula.

• Add sliced red onion, cherry tomatoes, parsley, or capers.

The fiber from beans helps support digestive health and stable blood sugar levels.

For a quick dinner:

• Toss canned tuna and artichoke hearts with whole-wheat pasta.

Avoid overcooking tuna can become dry quickly.

7. Broiled Tuna with Asian-Inspired Marinade

Marinate tuna steak for 15 minutes in:

• Soy sauce

• Sesame oil

• A touch of honey

Broil until just done. Serve with bok choy or asparagus and a side of brown rice for added fiber.

8. Seared Tuna Over Salad Greens

Lightly seared ahi tuna makes a restaurant-worthy meal at home.
