A coalition of Canadian medical groups wants all food companies to be required to clearly disclose on the label if the amount of sodium in their products exceeds Health Canada's targets. The move comes as the World Health Organization recommended new daily consumption limits on sodium for children. The public health advice aims to reduce blood pressure. High blood pressure increases the risk of heart disease and stroke. "Foods that fail to meet Health Canada's sodium-reduction targets …would be required to disclose that fact on food labels so long as that failure persists," the Centre for Science in the Public Interest said in a statement Thursday.
