The popular term ‘cold and cough’ refers to the coughing symptoms that occur in patients with the common cold. These patients should ensure that they are well hydrated and have adequate calories in their daily lives. Drinking enough water daily helps to keep the mucous membranes of the respiratory tract moist and conducive to coughing and phlegm. Also ensure that you consume sufficient protein and vitamins, such as lean pork, eggs, pears and oranges. It is important to note that the severity of each patient’s condition can vary significantly and that diet is only one part of the treatment of the disease. Therefore, if you are unwell, it is advisable to seek medical advice and your doctor will be able to formulate an appropriate treatment plan for you and give you sound dietary advice.
