We've all heard about eating fish to get more Omega-3's fatty acids in our diet. I was browsing through CNN.com and ran across an
article on omega-3 in canned fish. Of the types of canned fish discussed the focus was on tuna and salmon. Tuna varieties have varying amounts amounts of omega-3's. Albacore, also called "white meat tuna," has the most with a four-ounce serving packed in water having 1.06 grams. You get 0.5 grams from a four ounce serving of albacore packed in oil. I thought this was interesting that the water pack is better for you having more omega-3's. The article says, "Since omega-3s are oils, they don't disperse when the fish is packed in water, and draining the water allows most of these beneficial fatty acids to remain in the fish. But tuna packed in oil provides an environment where the fish's natural oils intermingle with the packing oil, so when the can is drained, some of the omega-3 oils are lost."
I didn't realize that canned salmon has even more omega-3's than tuna, with a four ounce serving having 2.2 grams. Unlike tuna, the omega-3 levels among salmon varieties are basically the same.
