Which tuna has less mercury albacore or yellowfin?

It's also high in omega-3 fatty acids. Canned light tuna is the best option with less mercury, according to the FDA and the EPA. Canned albacore and yellowfin tuna have a higher mercury content, but you can still eat them. Bigfoot tuna should be completely avoided, but that species isn't used for canned tuna anyway.

If you are a fan of sushi or you like to cook steaks on the grill, this is what you want. When choosing, the main thing to consider here is the size of the fish and the amounts of mercury. As a general rule, the larger the fish, the more mercury it contains. Some of the largest varieties with the highest mercury content are bluefin tuna, bigeye, yellowfin and albacore, but yellowfin and albacore contain half as much mercury as bigeye tuna.

It gets even more confusing: both bigeye and yellow-fin tuna are commonly referred to as “ahi tuna”. You can ask your waiter to specify the next time you place your sushi order. What types of tuna do you use? Our “light” tuna is mainly sautéed or yellow-fin tuna. Our “white tuna” is white tuna.

Nutritionally speaking, all types of canned tuna offer lean proteins, omega-3 fats, selenium and other important nutrients. Albacore tuna is found in tropical and temperate waters of all oceans, including the Mediterranean Sea. While white tuna is slightly higher in fat and calories, the difference is small enough not to deter you. The worst case scenario is when the nets are used with floating fish aggregation devices (FAD), which attract all types of marine life, not just tuna, says Carrie Brownstein, global seafood quality standards coordinator at Whole Foods Market.

According to Hocevar, tuna fishing kills millions of sharks and hundreds of thousands of sea turtles every year. Canned tuna meets all health and safety standards set by the FDA, which has set the maximum safe level of methylmercury allowed in commercial seafood at 1.0 parts per million. Five of the most commonly consumed low-mercury fish are shrimp, canned light tuna, salmon, pollock and catfish. Most other albacore tuna fisheries, including those for canned albacore tuna, use longlines, which often catch sea turtles, seabirds and sharks.

The calories are about the same for both of them (white tuna has about four more calories per ounce) and each has about 20 grams of protein per three-ounce serving. Light tuna in chunks is a smaller type of tuna; when canned, it has a softer, flakier texture and may have a stronger flavor. Canned tuna packaged in water and oil is delicious (especially the sophisticated imported types packaged in olive oil), but all that oil increases fat and calories. Adults, including pregnant women, can safely eat this type of tuna up to three times a month (women, 6-ounce servings; men, 8-ounce servings).

And don't assume that that expensive can of tuna packed in oil means anything other than, well, that it's packed in oil instead of water. Tuna species tend to be highly migratory species, but blackfin tuna differs from most other tunas in that it is limited to the western Atlantic Ocean, which is found approximately from Rio de Janeiro (Brazil) to Massachusetts.
