Navigating the Seafood Aisle: A Buyer’s Guide

Fresh vs. Frozen:

Both fresh and frozen fish can be nutritious choices. If purchasing frozen fish, ensure it is free of additives and choose options labeled as “wild-caught” for optimal quality.


Consider the environmental impact of your seafood choices by opting for sustainably sourced fish. Look for certifications such as the Marine Stewardship Council (MSC) or recommendations from reputable seafood guides.
