Miscellaneous


In this episode Danny and Alan discuss the current evidence base related to sodium intake and health, most notably cardiovascular disease. The episode walks through understanding diet-disease relationships, the epidemiology of sodium and health outcomes, the reasons for conflicting conlusions, sodium measurements in research, intervention trials, and more. Importantly, the claim that the sodium-CVD risk relationship exhibits a "J-shaped curve" (i.e. risk is low at moderate intakes and higher at both low and high intakes) is dissected, with recommendations given on how to reconcile all the available evidence.
