read the label if you're worried about your foods. Personally, I would worry that Ketchup has more sugar per ounce than a Coke. As for sodium, we need a certain amount each day to be healthy, going over or under isn't ideal. However, unless you are using huge amounts of ketchup and eating refined foods with extra salt on them, I wouldn't be overly worried about sodium intake.
