Barbecue sauce, packet gravies and sauces are also offenders; almost all brands contain extremely high levels of sodium. Olives, capers, and anything pickled are on the bad list too, because pickling requires salty brine. It’s also important to realise that the salt content in condiments is often listed for small quantities, so those who eat ketchup on everything or like their pasta with lots of sauce could be eating double or triple the dose of the sodium listed. And that dehydrated onion soup mix used to make so many party dips? It’s one of the worst traps of all, with more than 3,000 mg of sodium in one packet!
