Despite most of us knowing we should cut down on salt, Australians consume on average almost twice the recommended daily maximum per day.
Salt has been used in food preservation for centuries, and idioms like “worth your weight in salt” indicate how valuable it was for preserving food to ensure survival. Salt draws moisture out of foods, which limits bacterial growth that would otherwise spoil food and cause gastrointestinal illnesses. Today, salt is still added as a preservative, but it also improves the taste of foods.
