&gt; Absolutely, too much sodium, sugar, etc etc is unhealthy, and this absolutely not nonsense.<p>But &quot;too much is unhealthy&quot; is a tautology. There are a number of studies that show that sodium-restricted diets may increase all-cause mortality. So &quot;too much sodium...is unhealthy&quot; is not nonsense but completely meaningless and unhelpful as advice.<p>We generally know much less about nutrition than is commonly portrayed.
