Is the Nutritional Value of Fresh Fish Compromised When Canned?

Does canned fish (salmon or tuna) have any sort of nutritional benefit when compared to fresh fish?

Canned light tuna, ordinarily made from skipjack tuna, actually poses a substantially lower risk in terms of mercury exposure than fresh yellowfin or albacore tuna. So this type of tuna-canned light tuna-is the type that's best for you to buy if you want to eat tuna relatively often, for example, about one meal per week. While canned light tuna might not provide you with more nutrients than fresh light tuna, it is still likely to be saving you nutrient supplies by allowing your body to avoid processing unwanted mercury.

A second type of fish that can have some surprising benefits when canned is salmon. Because canned salmon is often packed in its own oil, you may be getting the benefit of some extra omega-3 fatty acids. Canned salmon also includes the bones (which are safe to eat since they soften during the canning process) and these bones can provide you with some added nutritional benefits as well. For example, a 3-ounce serving of salmon has over half the calcium found in an 8-ounce glass of cow's milk.
