Sardines with bones and skin are delicious, too, and they look awesome on top of a salad or platter. P.S. The bones and skin are both edible. Those tiny bones deliver calcium too!
You can even buy skinless, boneless sardines, but don't be put off by the skin and bones – these are actually very nutritious, and because the sardines are canned, the skin and bones are often very soft and easily digested. Just be aware that varieties packed in olive oil will be a bit higher in calories and fat.
Fish such as sardines, pilchards and herring are delicious to eat whole, but not everyone likes all the small bones – although they are edible.
You can buy tinned sardines that are skinless and boneless, but the skin and bones are completely edible, supply a good amount of sardines' calcium content, and are soft enough that most people don't even mind (or notice) them.

Sardines are at the bottom of the food chain and feed entirely on plankton. For this reason, they are much safer for eating, even with their guts, than many larger species of fish that build up heavy metals and contaminants in their tissue throughout their lifetime.
Sardines are high in protein, rich in omega-3 fatty acids (associated with heart health benefits), and filled with certain important vitamins (especially D and B12) and minerals (such as calcium). However, sardines packed in oil are high in sodium and cholesterol, so daily consumption of them is not advisable.
Sardines are also superior to canned tuna in their calcium and vitamin E content—an average serving provides 182 mg of calcium (14% DV) and 1.75 mg of vitamin E (8% DV), while a serving of tuna contains only 11 mg of calcium (1% DV) and . 75 mg of vitamin E (3% DV).
While they are both excellent sources of protein and add to your nutrient profile, the benefits of fish tend to be slightly higher than chicken, especially when it comes to the Omega-3 content in it.
Sardines
Sardines provide 2 grams of heart-healthy omega-3s per 3 ounce serving, which is one of the highest levels of omega-3 and the lowest levels of mercury of any fish.
You can simply eat canned sardines as are. You may want to drain the liquid they come in. You can easily add some oil, mayonnaise, hot sauce, mustard, or other seasonings; put them into a salad, or grill with some onions and garlic to seal in additional flavour.
Because sardines are fish, they do have heads. Although sardine heads are perfectly safe and healthy to eat, most modern consumers of tinned sardines would prefer not to eat the heads or innards, and so they are removed at the factory before being cooked, flavored, and packaged.
Sardines contain significantly less mercury than salmon, so even if you had two standard-sized cans of sardines (~3 ounces / ~84 grams drained), that's still only ~6 ounces of a safer fish in terms of heavy metals. In fact, you could have 4–5 cans of sardines and still be safe!
Still, tuna is high in protein, omega-3 fatty acids, and Vitamins B and A. This fish is also a good source of iron, phosphorous, and selenium. Sardines do not have a lot of mercury in them, so they're healthier in that regard.
There are a whole lot of options when it comes to sardines, but the best are packed in olive oil. Water-packed sardines just won't have the same rich flavor and can taste a bit water-logged. Oil, however, locks in the fish's flavor and keeps each sardine super-moist.
They're entirely different species. Anchovies (Engraulis encrasicolus, if you wanted to know) are smaller than sardines (Sardina pilchardus)—4 to 10 inches long compared to 6 to 12. Anchovies are more likely to be salt cured, and the tiny dark-brown filets are sold canned or jarred in olive oil.
Yes, that is sardine roe. In Portugal it is considered a delicacy on a par with caviar.
Because sardines contain purines, which break down into uric acid, they aren't a good choice for those at risk of kidney stone formation. The high sodium in sardines can also increase calcium in your urine, which is another risk factor for kidney stones.
Fortunately, just one can of sardines goes above and beyond your daily vitamin B12 needs, providing 137 percent of the amount that you need in a day. High in Selenium. Sardines also provide high levels of selenium, containing nearly 70 percent of your daily needs in just one can.
