Two papers from the Prospective Urban Rural Epidemiology or PURE study estimate sodium and potassium intake based on a single fasting morning urine specimen in more than 100,000 adults from 18 countries. Participants were followed for 3.7 years.
Researchers report on the relationship between estimated sodium and potassium levels on blood pressure levels and on death and cardiovascular events, a Forbes article said.
The PURE researchers suggest there might not be benefits to a moderate- or low-sodium diet.
The studies are reported in the New England Journal of Medicine.
Bonnie F. Liebman, nutrition director for the Center for Science in the Public Interest, said the results of the PURE studies shouldn’t change advice by health authorities – such as the American Heart Association and Centers for Disease Control and Prevention – to consume less salt to reduce the risk of cardiovascular disease.
