About Subway tuna sandwich
The Subway Tuna Sandwich combines flaky tuna mixed with mayonnaise and is served on fresh bread with optional vegetables and spices. Originating from Subway’s classic American fast-food menu, it represents a quick, customizable meal choice. The nutritional profile of the tuna sandwich varies by ingredients, but a typical 6-inch serving contains around 480 calories, 20 grams of protein, and 25 grams of fat. Tuna is rich in omega-3 fatty acids, known for supporting heart health, while the bread and vegetables provide carbohydrates, fiber, and micronutrients like vitamin C and potassium. However, it is high in sodium (approximately 600 mg), which should be factored when considering overall daily intake.
Health Benefits
- Omega-3 fatty acids in tuna support cardiovascular health and reduce inflammation.
- Tuna provides high-quality protein essential for muscle repair and cellular function.
- Vegetables like lettuce and tomatoes add dietary fiber and antioxidants such as vitamin C.
Dietary Considerations
Selection and Storage
Consume the sandwich fresh. If stored, keep it in the refrigerator and eat within 24 hours to maintain texture and avoid spoilage.
Common Questions About Subway tuna sandwich Nutrition
How much protein and calories are in a Subway Tuna Sandwich?

Is a Subway Tuna Sandwich suitable for a keto or low-carb diet?
A standard Subway Tuna Sandwich is not keto-friendly due to the bread, which contains roughly 38 grams of net carbs in a 6-inch serving. However, you can make it keto-compatible by skipping the bread and opting for a tuna salad bowl with low-carb vegetables and no sugary dressings.
What are the health benefits or concerns of eating a Subway Tuna Sandwich?

However, the mayonnaise used in the tuna mix contributes significant fat and calories, and some concerns exist regarding the sodium content, which is about 580-600 mg per 6-inch serving. Moderation is key, especially for those monitoring fat or sodium intake.
What is the recommended portion size for a Subway Tuna Sandwich?
A 6-inch Tuna Sandwich is a standard serving size and works well as a meal for an average adult. If you're looking to reduce calorie and sodium intake, consider pairing half a sandwich with a side salad or swapping high-calorie sauces for lighter options.
How does the Subway Tuna Sandwich compare to other Subway sandwich options?
The Tuna Sandwich is one of the higher-calorie options due to the mayonnaise in the tuna mix. For a lower-calorie alternative, you might consider the Turkey Breast Sandwich (250 calories for a 6-inch) or Veggie Delite (230 calories). However, the Tuna Sandwich offers more omega-3 fats and protein compared to these alternatives.
