Why is albacore better

But several species of tuna — like other large ocean fish — contain higher-than-average amounts of mercury, a highly toxic metal that can cause severe health effects. This is of particular concern for young children, since their nervous system, brain, heart, kidneys and lungs are all susceptible to the harmful effects of mercury. Mercury comes from both natural sources — like volcanoes — as well as man-made sources like air pollution from power plants and other industrial sources that burn fossil fuels.

Chunk indicates the size of the pieces of tuna in the can. Solid tuna means that it has larger, firmer pieces with fewer flakes; whereas chunk tuna comes in smaller pieces that vary in size. But through it all, keep in mind that only albacore will do. Nutritionally, all types of canned tuna offer lean protein, omega-3 fats, selenium, and other important nutrients. We like solid and chunk tuna for different reasons, and tend to use both for a variety of canned tuna recipes.

According to a June study published by the Society of Environmental Toxicology and Chemistry , hair mercury levels in university students consuming tuna three to 20 times per week were significantly higher than in non-tuna eating students, with those eating the most tuna having mercury levels of concern. Mercury levels from eating tuna are of particular concern when it comes to pregnant and nursing women and small children.

The U. Food and Drug Administration FDA recommends 8 to 12 ounces of seafood per week for pregnant or nursing women. The FDA's recommendation cites high levels of protein, vitamin D, selenium, B12, omega 3 fats and trace minerals. However, chunk light tuna is the only type of tuna recommended by the FDA as a "best choice," with two to three servings per week considered safe for consumption. White albacore tuna is a "good choice," but only recommended for consumption once a week, due to its higher mercury levels, which can be up to three times the amount of yellowfin tuna mercury, or that found in other fish, according to the University of California, San Diego.
