What It Is

"Whole fresh tuna from named species."

Health Impact

Good protein source but carries a minor mercury concern compared to smaller fish. Tuna is a larger predatory fish that can accumulate methylmercury over its longer lifespan. Fine in rotation; not ideal as the sole daily protein. Score: 8/10.

Why This Grade

A minor caveat applies — usually a processing step (e.g. rendering into a meal), a moderate allergen history, or a named-but-fattier source — but nothing on our risk watchlist. -1 pt deducted.
