The average Canadian eats twice the sodium he or she should, says Health Canada, and those extra pinches of salt can lead to an increased risk of heart disease and stroke. This salt-savvy app from the Canadian Stroke Network helps you cut down on sodium by tracking the salt content in packaged and takeout foods. Sodium 101's other features include a sodium thermometer to chart your daily intake, a recipe converter and a simulated saltshaker that monitors the salt in your favourite dishes.
