You probably already know that you're supposed to be eating fish twice a week. Fish are a lean, healthy source of protein and the oily kinds, such as salmon, tuna, sardines, etc. deliver those heart- and brain-healthy omega-3 fats you've probably also heard you should be getting in your diet. (Find out if you need an omega-3 supplement here.)  

 

But then there's also this concern about sustainability and choosing seafood that's sustainable.  

 

It can get confusing. How do you choose fish that are good for you and good for the environment?    

 

Fortunately, Rodale Press has compiled a list of the 10 Healthiest Fish on the Planet, which takes all of these considerations into account.
