What is the prudent consumption frequency for an average healthy adult eating Grouper?

Occasionally, perhaps once or twice a month.

For the average healthy adult, the consumption strategy for Grouper should reflect its status as a species positioned in a 'tricky middle ground'—offering good nutrition but carrying a noted mercury concern due to its predatory nature. While general fish consumption is encouraged twice weekly for cardiovascular and brain health, treating Grouper as a 'weekly staple' is deemed less prudent due to its risk profile. The most cautious approach suggested is incorporating Grouper as an 'occasional' indulgence, limiting intake to perhaps just once or twice a month. This moderation strategy allows enjoyment of its texture and protein content while mitigating consistent exposure to higher levels of common environmental contaminants found in top-level predators.
