Sardines are generally better than tuna as they're more nutrient-dense, lower in mercury, and packed with significantly more omega-3s, calcium, vitamin D, and B vitamins, supporting heart, brain, and bone health, while tuna, though high in protein, can have higher mercury levels, especially certain types. Both are great protein sources, but sardines offer superior nutritional value per serving.
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.
