In many parts of the world consumption of fish and seafood comprises a key proportion of man's diet and health. Despite of having many benefits, eating fish can be dangerous for instance the existence of nonorganic material, especially heavy metals, in some fish is dangerous. There are numerous fish breeding pools across the Lorestan province of Iran and the majority of the people living in these areas consume these kinds of fish, so, we were impelled to carry out a study to compare the nutrients and also heavy metals existent in freshwater fish and seawater fish available to the public across Khorramabad city of Iran. In this cross-sectional study, 9 samples of each five species of freshwater and sea water fish were purchased and their total protein, fat, omega 3, 6, and 9 fatty acids and also their heavy metals content including mercury, lead and cadmium of them were measured. There were no significant differences between mean protein content of the two types of fish. The amount of total fat and omega 3, 6 and 9 fatty acids of freshwater fish was higher than of seawater fish (P>0.001). The levels of cadmium in seawater fish was significantly higher than freshwater fish (P>0.001), and as for the level of mercury and lead, no significant difference was observed between the two types of freshwater fish and seawater fish. According to the results, we recommend that people can secure a part of their protein and unsaturated fatty acids need by consuming freshwater fish.
