Packaged Tuna Fish

Canned tuna is widely available and often less expensive; pouched tuna is lightweight and resealable for convenience; premium packed tuna (olive-oil or hand-packed) usually contains larger chunks or higher-quality fillets and is marketed for taste and texture rather than price

Look at the type of tuna (skipjack, albacore), sodium content, added oils or sauces, and calories per serving; check for simple ingredient lists (tuna, water or oil, salt) if you want fewer additives

Mercury levels vary by species and size—albacore tends to have higher mercury than skipjack—so follow dietary guidance for weekly servings; for sustainability, look for third-party certifications or on-package sourcing statements indicating pole-and-line, troll-caught, or MSC certification when available

Lower-priced options are often chunked and packed in water or lower-cost oils, while higher-priced products commonly use whole fillets, premium oils, or specialty preparations; price reflects processing, packaging type, and brand positioning rather than nutritional value alone

Unopened cans or pouches are shelf-stable and should be stored in a cool, dry place; after opening, transfer unused tuna to a sealed container and refrigerate, consuming within 2–3 days for best quality

Check the Nutrition Facts panel for grams of protein and milligrams of sodium per serving; for lower sodium, compare 'low sodium' or 'no salt added' labels and consider rinsing tuna packed in brine to reduce surface salt

Packaged tuna is safe for salads and cold preparations; for sushi-grade raw applications, use products specifically labeled as safe for raw consumption or follow food-safety guidance—most canned and pouched tuna are cooked during processing and are ready to eat
