Presentations at the International Society of Hypertension in Beijing
Two PhD candidates from the WHO CC team recently presented their research at the 27th Scientific Meeting of the International Society of Hypertension in Beijing, China. Kathy Trieu presented findings on mean 24-hr urinary salt excretion in two regions of Kazakhstan. These populations had extremely high salt intakes, possibly the highest in the world. The […]
Label v. Lab: How do sodium values compare?
A study by Ahuja et al compared the sodium values on product labels with laboratory values of popular sodium-contributing foods in the US. The comparative analysis of 114 foods (1,390 composites, consisting of one or more samples of the same food) showed that a majority of label and laboratory values were in agreement. Periodic monitoring […]
Web based learning improves salt-smarts in children (Victoria, Australia)
