There is no fastest dietary treatment for cold and cough, because dietary treatment generally does not have the exact effect of relieving cough, but through dietary modification, it may have some help in the recovery of the disease. When you have a cold or cough, you need to make dietary adjustments, such as eating a light diet, eating some apples, oranges and other fruits. The above mentioned diets are only for regulating the cough and do not have a clear effect of relieving the cough quickly; however, improper diet may not be conducive to the recovery of the cold and cough, for example, eating chili peppers or drinking cold beverages is not conducive to the recovery of the disease. Therefore, when the symptoms of cold and cough are prominent, it is necessary to consult a doctor in a timely manner, under the guidance of the doctor to standardize the treatment, rather than simply through the diet to deal with.
