Do salty foods cause a cough to get worse?

Salty foods can sometimes aggravate a cough, especially if they lead to dehydration or irritation in the throat. High salt intake may cause the throat to feel dry or scratchy, which can exacerbate coughing. Additionally, if a cough is related to an underlying condition like acid reflux, salty foods might worsen symptoms. However, the effect can vary from person to person.
