U.S public health authorities recommend maximum daily sodium consumption of 2.3 grams a day, in order to prevent cardiovascular disease. But a 2018 multi-country study published in Lancet supports a much different and higher maximum sodium intake level:
Sodium intake was associated with cardiovascular disease and strokes only in communities where mean intake was greater than 5 g/day. A strategy of sodium reduction in these communities and countries but not in others might be appropriate.
The researchers also found, “All major cardiovascular outcomes decreased with increasing potassium intake in all countries.”

You’ll find several cold-water fatty fish there.
My Low-Carb Mediterranean Diet recommends the fish but you’ll find no sodium restriction advice.
