Tuna Salad Calories

Key takeaways

• 1 cup (205 g) of classic tuna salad has 383 calories on average, according to USDA data.
• The macro split for that serving is about 54% fat, 15% carbs, and 31% protein.
• A lighter homemade version can be as low as 194 calories per cup while still providing 17 g of protein.
• Calories vary depending on whether the tuna is packed in oil or water, and whether you use mayonnaise, Greek yogurt, or a fat-free dressing.
• Tuna salad can fit into Keto, Paleo, Mediterranean, Weight Watchers, and Pescatarian eating patterns when built with lean ingredients.
• Tuna provides high-quality protein, omega-3 fatty acids, vitamin D, and B vitamins, nutrients associated with heart, brain, bone, and immune support.

If you’re wondering how many calories are in tuna salad, the short answer is: it depends on the recipe. A traditional tuna salad made with mayonnaise is much richer in calories than a lighter version made with tuna packed in water and a yogurt-based dressing. It also depends on how the tuna was packed: tuna in oil or tuna in water.  

For example, this classic tuna salad recipe has only 194 calories for a 1 cup serving while still delivering 17g of protein. And you can also personalize your nutritious tuna salad by incorporating extras. Consider adding ingredients such as capers, pickles, cucumbers, tomatoes, or boiled eggs.

Why does 1 cup equal 7.2 ounces instead of 8? Because cup measurements depend on density, and tuna salad contains ingredients like tuna, mayonnaise, and chopped vegetables that affect volume and weight.
