However, consumers often question whether this processed pantry item is truly a healthy choice, especially when it comes to specific brands and preparations like StarKist Chunk Light tuna in water. A comprehensive evaluation requires looking beyond the protein content to consider factors like the type of tuna, canning liquid, sodium levels, and potential mercury exposure.

Omega-3 Fatty Acids
While light tuna has lower levels of omega-3s than fatty fish like salmon, it still contributes beneficial amounts of DHA and EPA, which support heart and brain health. The water-packed variety of Chunk Light tuna provides around 160 mg of EPA and DHA omega-3s per serving. These essential fatty acids are crucial for reducing inflammation and maintaining overall wellness.

Canned Tuna: Water-Packed vs. Oil-Packed
Your choice of canned tuna can significantly alter its nutritional impact. Packing tuna in water versus oil has different effects on its calorie, fat, and flavor profile. This table highlights the key differences:
| Feature | Water-Packed Tuna | Oil-Packed Tuna |
|---|---|---|
| Calories & Fat | Lower in calories and fat, which is beneficial for weight management. | Higher in calories and fat due to the added oil. |
| Flavor | A cleaner, more straightforward flavor since no oil is infused into the fish. | Richer, more pronounced flavor with a more tender texture. |
| Texture | Firmer and drier texture, which works well in salads, casseroles, and tuna patties. | Softer and more succulent texture due to the oil permeating the fish. |
| Best For | Lighter meals, sandwiches, or dishes where you control the added fat. | Flavor-forward dishes like antipasti or gourmet sandwiches where the richness is desired. |
Addressing Health Concerns: Mercury and Sodium
Managing Mercury Levels
One of the most persistent concerns about canned tuna is its mercury content. The good news is that Chunk Light tuna is considered a safer, lower-mercury option than other varieties.
- Light Tuna vs. Albacore: Research shows that canned light tuna has significantly lower total mercury levels compared to white (albacore) tuna, a larger species. This is because skipjack tuna (the primary type of light tuna) are smaller and have a shorter lifespan, accumulating less mercury over time.
- Safe Consumption: For most healthy adults, consuming canned light tuna a few times per week is considered safe. The FDA and EPA provide guidelines to help people, especially vulnerable groups like pregnant or breastfeeding individuals and young children, make informed choices to minimize exposure while still reaping the health benefits of fish.
Controlling Sodium Intake
Standard canned tuna contains a moderate amount of sodium. A 5 oz can of StarKist Chunk Light tuna in water has 360mg of sodium, or 16% of the daily value. For individuals monitoring their sodium intake, StarKist offers a 25% less sodium version of its Chunk Light tuna, which is a great alternative. Rinsing the tuna can also help to further reduce the sodium content.
Health Benefits of Incorporating Tuna into Your Diet
Adding canned tuna to your diet offers several notable health advantages, beyond just protein and omega-3s. These benefits include:
- Supports Heart Health: A higher intake of fish is linked to lower rates of coronary heart disease. The omega-3s in tuna, combined with its low saturated fat content, make it a heart-healthy choice.
- Aids in Weight Management: The high protein content promotes feelings of fullness, which can help reduce overall calorie consumption. The low-fat, low-calorie profile of water-packed tuna makes it a smart choice for those on a calorie-controlled diet.
- Boosts Brain Function: The DHA and EPA omega-3s are crucial for maintaining brain health and function throughout your life.
- Contributes to Vitamin D Intake: Tuna is one of the few natural food sources of vitamin D, a nutrient many people do not get enough of.
