Is tuna salad healthy?

It certainly can be! On its own, tuna is a very healthy protein, containing B6, B12, vitamin A, iron, zinc, magnesium, potassium and omega-3 fatty acids. When buying canned tuna, choose the fish packed in water instead of oil to avoid extra fat and calories.

The other ingredients in the tuna salad recipe—especially mayonnaise or dairy—will determine if it’s healthy. With reduced-fat mayo, onion, celery, tomatoes and herbs, this one is a nicely healthy tuna salad recipe.

Tips for Healthy Tuna Salad

What’s the healthiest type of tuna?

When choosing between oil- or water-packed tuna, water is usually the healthier option. Oil-packed tuna generally has a richer taste but you won’t know the quality of the olive oil used. Water-packed tuna may have higher levels of omega-3 fatty acids, as well as fewer artificial ingredients.

To buy more sustainable tuna, look for labels that say the tuna was caught by pole or line fishing. These methods are more environmentally sustainable than other options. These are our Test Kitchen’s favorite tuna brands.

What are some good substitutes for mayo in tuna salad?

While mayonnaise is almost always linked with tuna salad, it has no special powers that make it the only option for tuna salad magic. Mayonnaise is used to smooth out the tuna salad and bind the ingredients together, but these alternatives work just as well and add additional flavor:

  • Mustard
  • Hummus
  • Plain Greek yogurt
  • Mashed avocado
  • Chimichurri
  • Olive tapenade
  • Cottage cheese
  • Olive oil and red wine vinegar
  • Pesto
  • Aioli
  • Tzatziki sauce
  • Ricotta cheese
