Tuna can be a good source of omega 3 fatty acids. Tuna is also a good source of protein. Try Unico Tuna in Extra Virgin Olive oil all on its own, in sandwiches and even salads. It is our policy to only source products from fisheries that follow the guidance of the WWF supported and science based organization specifically focused on ensuring the continued health and survival of the worlds tuna stocks, the ISSF (International Sustainable Seafood Foundation).
