What Species of Tuna Does StarKist Use?
Yes, StarKist uses real tuna, and the specific species varies depending on the product you choose. All StarKist tuna is wild-caught, meaning it is not farm-raised. The main types you'll find in cans and pouches are Skipjack, Yellowfin, and Albacore. The label on the packaging will indicate whether the product is 'light' or 'white,' which corresponds to the species used.
- Light Tuna (Chunk Light): This is typically made from Skipjack tuna, a smaller species known for its darker, tender, and flavorful meat. Some light tuna products may also contain Yellowfin, a slightly larger and more premium species. Skipjack is the most commonly consumed tuna species globally and has the lowest mercury levels.
- White Tuna (Solid White or Chunk White): This product is exclusively made from Albacore tuna. Albacore has a much milder flavor and a firmer, paler texture, often compared to chicken breast. Due to its larger size and longer lifespan, Albacore generally contains higher levels of mercury than Skipjack.
How Tuna is Processed by StarKist
The journey of StarKist tuna from the ocean to your plate involves a series of stringent quality control measures to ensure safety and quality.
- Catch and Transport: Tuna are caught and immediately frozen on board the fishing vessel to maintain freshness.
- Thawing and Inspection: Upon arrival at the processing plant, the fish are thawed and meticulously inspected.
- Cooking and Cleaning: The tuna is pre-cooked or steamed, then cleaned by hand, and separated into fillets.
- Filling and Sealing: Depending on the product, the fish is either chunked or kept as a solid fillet and packed into cans or pouches. Additional ingredients like water, oil, or vegetable broth are added. The containers are then vacuum-sealed.
- Sterilization: The cans or pouches are cooked at high temperatures in a retort (a large pressure cooker) to sterilize the contents and ensure a long shelf life.
Nutritional Comparison: Light Tuna vs. White Tuna
| Feature | Light Tuna (e.g., Skipjack) | White Tuna (Albacore) |
|---|---|---|
| Appearance | Light tan to pinkish | White to very light pink |
| Texture | Softer, more tender | Firmer, meatier |
| Flavor | Stronger, more pronounced 'tuna' flavor | Milder, less 'fishy' flavor |
| Omega-3s | Good source, but generally lower than Albacore | Slightly higher in Omega-3 fatty acids |
| Mercury Level | Classified as 'low' by the FDA | Classified as 'moderate' by the FDA |
| Dietary Use | Versatile for salads, sandwiches, and casseroles | Ideal for dishes where a milder flavor is preferred |
Incorporating Tuna into a Healthy Nutrition Diet
As part of a balanced diet, tuna offers a wealth of nutritional benefits, including lean protein, Omega-3 fatty acids, and essential vitamins and minerals. The American Heart Association recommends eating two servings of fatty fish, like tuna, per week. Here are some key nutritional takeaways:
- Protein: Tuna is a fantastic source of high-quality protein, which is essential for building muscle, repairing tissues, and helping you feel full and satisfied.
- Omega-3s: Rich in DHA and EPA Omega-3 fatty acids, tuna supports heart health, brain function, and helps reduce inflammation.
- Vitamins and Minerals: Canned tuna provides important nutrients like Vitamin D, B vitamins (especially B12), and Selenium. Selenium is a powerful antioxidant that can help protect against mercury toxicity.
Healthy Ways to Enjoy Tuna
- Salad Enhancer: Toss flaked tuna with leafy greens, vegetables, and a light vinaigrette for a protein-packed meal.
- Whole Grain Partner: Mix tuna with whole grain rice or quinoa for a filling and nutritious meal.
- Wrap or Sandwich: Use whole-grain tortillas or lettuce leaves to make wraps with tuna, sliced vegetables, and a low-fat dressing.
Understanding the Mercury Concern
Mercury is a naturally occurring heavy metal that accumulates in fish over time. It is a valid concern, especially for vulnerable populations like pregnant women and young children. However, canned tuna consumption can be managed safely by following official guidelines.
- FDA Recommendations: The FDA provides guidelines on safe tuna consumption. Light canned tuna (mostly Skipjack) has lower mercury levels and can be eaten more frequently than canned white (Albacore) tuna, which is a larger fish and accumulates more mercury.
- The Role of Selenium: As an antioxidant, selenium binds with mercury, rendering it less harmful to the body. Canned tuna contains significantly more selenium than mercury, providing a protective effect.

Conclusion
So, does StarKist use real tuna? The answer is a clear yes. StarKist offers consumers real, wild-caught tuna, with the specific species varying by product type. By understanding the differences between 'light' (Skipjack) and 'white' (Albacore) tuna, consumers can make informed choices to fit their dietary needs and health goals. Tuna is a valuable source of lean protein, healthy fats, and essential nutrients. While mercury is a consideration, especially for regular consumers, choosing lower-mercury light tuna and consuming it in moderation can allow you to reap the health benefits of this pantry staple with minimal risk.
