A new study published in the American Journal of Hypertension analyzed data from 8,670 French adults and found that salt consumption wasn’t associated with systolic blood pressure in either men or women after controlling for factors like age.
Why not? One explanation, the authors write, is that the link we all assume between salt and blood pressure is “overstated” and “more complex than once believed.” It should be noted, however, that even though the study found no statistically significant association between blood pressure and sodium in the diet, those patients who were hypertensive consumed significantly more salt than those without hypertension—suggesting, as other research has, that salt affects people differently.
As for the factors that did seem to influence blood pressure, alcohol consumption, age, and most of all BMI were strongly linked to a…
