Health Benefits of Tuna
1. Lean Source of Protein
Tuna is high in lean protein, supporting muscle growth and repair, while helping you feel satisfied after meals.
- A 3-oz serving contains about 18–22g protein.
- Protein promotes satiety and aids healthy weight management.
2. Rich in Omega-3 Fatty Acids
- Tuna delivers essential omega-3s (DHA, EPA) that combat inflammation, protect heart health, and promote optimal brain function.
- DHA and EPA have been linked to lower cardiovascular risk and improved mood.
3. Support for Bone Health and Immunity
- Vitamin D in tuna builds strong bones and boosts immunity.
- Most diets fall short in vitamin D—tuna provides a natural, substantial source.
4. Powerful Antioxidant Protection
- Selenium in tuna acts as an antioxidant and binds mercury, reducing its absorption in the body.
- Supports thyroid function, cardiovascular health, and cell protection.
5. Energy and Heart Health
- B Vitamins (B6, B12, niacin) found abundantly in tuna help convert food to energy.
- May lower the risk of heart disease, support brain health, and fight anemia.

6. Weight Loss & Management Benefits
Tuna’s combination of low calories, high protein, and minimal fat can be especially valuable for those trying to lose or manage weight:
- Low-calorie content helps reduce overall energy intake.
- High protein increases fullness and regulates appetite, reducing the desire for unhealthy snacks.
- Switching from higher-calorie meats (like beef) to tuna can cut calorie consumption by 4–9%.
Types of Tuna: Which to Choose?
Tuna comes in several varieties, each with its own characteristics:
- Skipjack (Light) Tuna: Lower mercury content, commonly available canned, and usually more affordable.
- Albacore (White) Tuna: Milder flavor, higher mercury levels than skipjack.
- Yellowfin (Ahi) Tuna: Firm texture, used for steaks and sushi, moderate mercury content.
- Bluefin Tuna: Most prized for sushi, highest mercury and tends to be overfished.
For regular consumption, light (skipjack) tuna is recommended due to its lower mercury content. It’s important to enjoy higher-mercury varieties like albacore and bluefin occasionally and not daily.
