Researchers With Opposing Views on Salt Intake Are Ignoring Each Other

Salt
 

Trinquart and colleagues reviewed 269 primary studies, analyses, clinical guidelines, consensus statements, comments and letters on salt intake and health published between 1979 and 2014. They sorted the papers based on whether or not they supported the link between reduced sodium intake and lower rates of heart disease, stroke, and death.

They found that 54% of papers supported the hypothesis, 33% refuted it, and 13% were inconclusive.

Those that supported the hypothesis tended to cite other papers that supported it, too, while those that refuted tended to cite others that refuted also, with little crossover between the camps.
