Excessive salt intake is a major cardiovascular risk factor. The main source of sodium in transitional and developing countries is not the processed food but salt added during the cooking procedure or at the table. The objective of this trial was to examine the impact of home salt containers’ labeling on daily salt intake. A sample of treated hypertensives (N= 139) was randomized in two groups, one receiving just a leaflet about the harmful effects of excessive salt consumption (control, N= 69), and the other one receiving in addition self- adhesive warning stickers for household salt containers (intervention, N= 70). Blood pressure (BP) and 24-hour urinary sodium excretion (Na24) were measured in all the subjects at the start of the trial, and 1, 2 and 12 months later. The average starting Na24 was 211.1±78.7 mmol, similar in both groups. One, two, and twelve months later a significant decrease in Na24 was observed in the intervention group (to 183.5±51.6 mmol ; P 0.286). It is concluded that a marked, long-lasting reduction in Na24 and BP may be achieved with warning labels on harmful effects of excessive salt intake. |
