I bring this to your attention because of the potassium link. Most of us have heard that reducing salt (sodium) intake is supposed to be good for us, although even that’s debatable. Fewer have heard that higher potassium may be good for us. Those diet characteristics—low sodium and high potassium—are naturally incorporated into the Paleolithic diet (aka Stone Age, caveman, hunter-gatherer or paleo diet).
Read MedPageToday for details. The association between sodium restriction and lower rates of cardiovascular disease and mortality is a confusing mess. My gut feeling is that strict sodium avoidance is important for only 20% of the population, at most. From MedPageToday:
However, the assertion that reduced salt intake will have beneficial effects on disease outcomes contradicts the results of a 2011 meta-analysis, which failed to show significant relationships between reduced salt intake and mortality or cardiovascular outcomes.
