How we got a town to drop its salt intake by a tenth
AUSTRALIAN adults are thought to consume 7-12 grams of salt per day, far exceeding the four grams suggested by the Australian government and the five grams suggested by the World Health Organisation.
From high blood pressure and stroke to heart attack and stomach cancer, the health risks of excess salt are well-established. This is why practical ways of bringing levels down are so keenly sought.
In 2011, based on urine samples from 400 people, the town of Lithgow in NSW consumed a mean 8.8 grams of salt per day.
