EATING FISH

 Recent studies have found salmon fraud in many eateries. Farmed salmon being mislabeled as wild salmon. Wild Caught definitely has more nutritional value due to its higher levels of omega 3 fatty acids and lower levels of pollutants (mercury, etc.). Alaskan salmon is wild caught, Atlantic is farmed.

 If you are ordering salmon or other fish in a restaurant or market it is helpful to know where they buy the fish and what part of the world it came from.
