Tuna is a saltwater finfish, choose wild caught tuna not farmed. When purchasing canned tuna, select pole and line caught, in brine or spring water (this will prevent the tuna being stored in unhealthy oils), also choose in a BPA free can. Read your labels and look at the origin. Tuna is a good source of omega 3 fatty acids, protein and vitamin D.
