How to Eat Tuna
Fresh tuna can be seared, grilled, or served raw in sushi and poke bowls. Canned tuna is versatile for sandwiches, salads, pasta dishes, and casseroles. For fresh tuna, cooking to medium-rare (125°F) preserves moisture and flavor. Canned tuna packed in water is lower in calories than oil-packed. Mix canned tuna with Greek yogurt instead of mayo for a healthier option.
Selection and Storage
Fresh tuna should have a deep red color without brown spots and smell clean, not fishy. Use within 1-2 days or freeze. For canned tuna, check expiration dates and choose low-sodium options when available. Light tuna (skipjack) is lower in mercury than albacore. Store canned tuna in a cool, dry place.
Dietary Considerations
Tuna is naturally low-carb, gluten-free, and suitable for keto, paleo, and Mediterranean diets. Due to mercury content, FDA recommends limiting albacore tuna to 6 ounces per week; light tuna can be consumed more frequently. Pregnant women should be especially mindful of tuna consumption.
