           Studies show that eating fish helps cut the risk of heart disease, cancer, Alzheimer's, stroke, diabetes and arthritis. The American Heart Association recommends that adults eat at least two fish meals per week, especially wild salmon, herring and sardines, because those varieties provide the most heart-healthy omega 3s.

            Researchers in Kodiak think that nutrition-minded consumers might buy more canned salmon if producers can promise consistent levels of omega-3 oils in every can. University of Alaska Fairbanks graduate student Trina Lapis has just completed a thesis on this topic based on research she's been performing with a team of scientists in Kodiak.

            The fat content of Pacific salmon varies naturally in wild-caught fish. That variation creates an inconsistency in the amount of omega-3 available in every serving of canned salmon.

            Lapis wanted to test what would happen if salmon oil is added to canned bright or dark pink salmon.

The study investigated how adding various amounts of salmon oil would affect the nutritional content of the product.

The next step was to test what scientists call the "sensorial" aspects of the canned salmon.

            When the results of the nutrition study and the taste tests were combined, the researchers were able to determine what amounts of salmon oil should be added to the canned products.

            Lapis said that federal regulations already allow for the addition of salmon oil to canned salmon. She also said that the oil can be rendered from the heads of the fish which would help processers reduce waste.

            The results of the study were presented Wednesday during a video teleconference between Kodiak and the University of Alaska Fairbanks campus.
