Get excess salt out of our diet

Added salt in our diets is unnecessary and contributes to health problems such as high blood pressure and strokes, write Dr. Ken Flegel and Dr. Peter Magner and the CMAJ editorial team http://www.cmaj.ca/press/pg263.pdf. Consumers must be vigilant, read food labels, avoid food with high salt content and demand low salt food in stores and restaurants.

"Of the estimated one billion people living with hypertension, about 30% can attribute it to excess salt intake," write the authors. They note that populations, such as the Yanomami Indians in South America, with very low levels of salt intake do not have hypertension. In contrast, Japan, with a salt intake of 15 g per person, has high rates of high blood pressure and the highest stroke rates in the industrialized world.
