Sardines are a type of small, oily fish that contain a lot of important nutrients. Both fresh and canned sardines have health benefits, including helping to fight inflammation and supporting the health of your heart, bones, and immune system.
Sardines may be small, but they make a great addition to a balanced diet, as they are low in saturated fat and calories, but high in protein. They also offer a good array of vitamins and minerals.
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.
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.
The fully processed products include canned tuna, salmon, shrimp, crab, sardines, and other fish, fish balls, and so on. The heating process applied to these products is designed to destroy pathogenic bacteria and normal numbers of other organisms.
The fact that a serving of sardines serves up a whopping 136% the RDV certainly helps its case as a superfood.

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.
The FDA recommends a weekly intake of two to three servings of sardines, or 8 to 12 ounces for adults and 4 to 6 ounces for children age 4 to 7. The FDA recognizes the health benefits of eating fish, especially for pregnant people and young children. Pregnant people can eat up to 12 ounces per week.
Similar to shrimp, sardines are a potent seafood source of cholesterol. An ounce of sardines contains as much as 40 milligrams of cholesterol, and it's easy to eat more than an ounce at a time.
Too much sodium can lead to high blood pressure, stroke, and heart disease —but “in the context of a varied diet, [tinned fish] likely won't make too much of a difference,” Rumsey says. Basically, if you don't eat it every day, at every meal, you're probably good.
The Dietary Guidelines for Americans states that to consume those higher amounts, children should only be fed fish from the “Best Choices” list that are even lower in mercury – these fish are anchovies, Atlantic mackerel, catfish, clams, crab, crawfish, flounder, haddock, mullet, oysters, plaice, pollock, salmon, ...

Omega 3s are good fats, and contributes to about 30% the brain's weight, and alter dopamine and serotonin, which are brain chemicals linked to mood. Adding omega 3s to your diet is good for your brain's health, and keeps brain cells flexible and have it work more efficiently.
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.
A study places salmon, sardines and anchovies among the most beneficial types of fish due to their high protein content. Grilled, boiled or steamed, fish is nutritionally far more highly recommended than meat. In fact, there's little that can trump it.
Grilling canned sardines is the perfect way to bring them to life, add some flavour, and give them a little more dignity if the whole 'canned' thing turns you off. Yes, they're already cooked so you just reheat them and give them a little charred edge.
Sardines are canned by one of two methods; Mediterranean or Norwegian. In the Norwegian method the sardines are held alive until their guts are empty. They are then smoked before being beheaded. In the Mediterranean method they are beheaded and gutted.
Did you know? Canning fish does not destroy omega-3s. Get more omega-3 fatty acids with canned salmon, tuna, sardines and herring. Omega-3s are a type of fat.
Adding sardines to a balanced diet can help improve blood vessel function, ease inflammation, and more. A Harvard study found that consuming just one to two servings of sardines every week provides enough omega-3 fatty acids to reduce your chances of heart disease by more than one-third.
"While canned tuna, especially light varieties, has relatively low average levels of mercury, individual cans can sometimes have much higher levels," Consumer Reports said.
Oil vs Water
Tuna packed in water will contain fewer calories and less fat but also allows for the loss of omega 3 fatty acids to occur. Water-packed also dilutes the natural juices and flavors contained within the fish and can lead to a more rounded and less refined taste.
