I stumbled across this little bit of info on canned salmon.....
Canned salmon is one of nature's healthiest and pure foods. Canned salmon contains only salmon sections with a little added salt to enhance the flavor. Nothing else is added in most cases. This analytical work was conducted by the Department of Food Science at the University of British Columbia (UBC), and summarized in a report entitled "Nutritional Analysis Of British Columbia Canned Salmon" This study reafirmed that BC canned salmon is a good nutritional source of well balanced and easily digestible protein, polyunsaturated fatty acids (PUFA), omega-3 fatty acids, calcium, potassium, vitamin 'D', the 'B' vitamins, and phosphorus. Calcium is an added bonus offered by canned salmon. The bones in canned salmon are soft and edible making canned salmon an excellent source of dietary calcium.
You can try different things with either of them. Just whatever you prefer.. I like it mixed with a little Dijon mustard or straight out of the can... I have heard others putting a little pickle juice in it to add a different flavor..
