Darker tuna isn't inherently "better"—it depends on the type and preference, as dark meat (skipjack, yellowfin bloodline) often means a stronger flavor, while lighter meat (albacore) is milder, but very dark, reddish tuna might be carbon monoxide-treated to look fresh when it isn't, so natural, deep red (like bluefin) is prized for sushi, while "chunk light" (darker) is great for salads.
Which tuna is better, albacore or chunk light? Albacore has a firm texture and mild flavor, while chunk light offers a softer texture and bolder taste. If you prefer less “fishy” flavors, go with albacore; for stronger flavor, chunk light is better.

If you're cutting back on calories and fat, choose tuna packed in water rather than oil. A 3 oz serving of water-packed light tuna has 73 calories and less than 1 g of fat.
Generally, albacore or white canned tuna costs more than light or chunk light tuna. That's due to several factors, including consumer demand; white tuna is also all albacore, while light can contain a combination of tuna species. Whether the tuna is one solid piece of filet or various pieces can also impact cost.
The healthiest canned fish are small, oily varieties like sardines, mackerel, anchovies, and herring (SMASH), packed with omega-3s, protein, vitamin D, calcium (especially with bones), and lower mercury, with anchovies and sardines often topping the list for overall nutrition and lower cost; salmon is also excellent but choose smaller species like canned sockeye or chum.

Tuna that is old, improperly refrigerated, or beginning to spoil turns brown/gray as myoglobin oxidizes. This discoloration makes it unsellable at full price, especially for sashimi or “ahi” marketing.
Tuna's dark red meat is also rich in an organic compound called selenoneine, which appears to not only be effective in preventing lifestyle diseases, but also in reducing stress and slowing the aging process.
Mercury (Hg) analysis was performed in white and dark muscle of Skipjack tuna fish. Overall, dark muscle contains higher Hg concentration than white muscle. Hg concentration increases significantly along the canning process. Ingestion of this canned product does not represent a risk in terms of human diet.
As per reports, a 243-kg bluefin tuna has become the world's most expensive fish. But the auction also raised questions around who bought it and why it is so expensive.

The Best Canned Tuna, Ranked

Children up to age six shouldn't eat albacore more than once a month (3 oz. portions); children ages 6–12, twice a month (4.5 oz.
Neither is universally “better”—it depends entirely on your personal health goals and taste preferences.

Pre-cooked pasta in sauce is one of the unhealthiest canned foods. While they might be tasty meals, the reason they have that addictive flavour is due to high levels of sugar and salt. For example, a can of Heinz Alphaghetti contains 1,490 mg of sodium and 18 g of sugar.
Yes, sardines are generally considered healthier than tuna because they are significantly lower in mercury, higher in omega-3s (EPA/DHA), and packed with calcium, vitamin D, and B12, though tuna offers more protein per serving, making sardines the more nutrient-dense choice overall with fewer contaminants.
The unhealthiest fish to eat are typically large, predatory species high in mercury like shark, swordfish, king mackerel, and imported tilefish, plus bluefin tuna, which are dangerous for brain/nerve health, especially for pregnant women and children; also, farmed salmon and some imported tilapia/catfish raise concerns for contaminants and antibiotics, while orange roughy and Atlantic cod are often cited for high mercury and overfishing/sustainability issues.
