Current evidence suggests that moderate dietary sodium intake (2.3-4.6 g/day) is not associated with increased cardiovascular risk, whereas risk increases when sodium intake exceeds 5 g/day.
Does low sodium intake (<2.3 g/day) reduce cardiovascular disease compared to moderate intake?
This review challenges universal low sodium guidelines, arguing that moderate intake (2.3-4.6 g/day) does not increase cardiovascular risk and that reduction targets should focus on populations consuming >5 g/day.
Several blood pressure guidelines recommend low sodium intake (5 g/day, while awaiting the results of large randomized controlled trials of sodium reduction on incidence of cardiovascular events and mortality.
“Some researchers have propagated a myth that reducing sodium does not consistently reduce CVD but rather that lower sodium might increase the risk of CVD. These claims are not well-founded and support some food and beverage industry's vested interests in the use of excessive amounts of salt to preserve food, enhance taste, and increase thirst.”
O’Donnell et al. (Fri,) conducted a review in Cardiovascular disease. Low sodium intake vs. Moderate sodium intake (2.3-4.6 g/day) was evaluated on Cardiovascular disease occurrence. Current evidence suggests that moderate dietary sodium intake (2.3-4.6 g/day) is not associated with increased cardiovascular risk, whereas risk increases when sodium intake exceeds 5 g/day.
