The average was nearly 4, mg of sodium a day. Yet the range was huge, from mg a day among the Yanomamo people of Brazil to 10, mg in northern Japan.
Four groups of people—the four countries with salt intakes less than 1, mg per day—had low average blood pressures and little or no upward trend of blood pressure with age.
The authors conducted a re-review and update on the Intersalt data. In each of the studies, small decreases in blood pressure were seen with sodium reduction over months.
