Most Canadians know they consume too much salt, and are well aware of the health risks, including high blood pressure, according to University of Alberta nutrition researchers. But only half of the 890 people surveyed are actually trying to cut down. Young people between the ages of 18 and 24, and families with young children are the least likely to know how much salt is too much. They also tend not to read nutrition labels. The researchers say salt-reduction messaging should target these groups.
