Even though we all know that chicken soup is good for colds and flu, packaged soups generally contain massive amounts of salt. A tin of soup, for instance, can contain as much as half the daily recommended salt intake. A packet of instant beef noodle soup can contain a whopping 700mg of salt, over 30% of the recommended daily intake. When it comes to soups, it’s best to avoid instant soups altogether (they’re laden with chemicals) and switch to ‘low-salt’ tinned varieties. If they taste bland, which is possible if you’re used to eating the highly salted ones, try beefing them up by adding herbs, spices and freshly ground black pepper.
