You can eat any fruit when you have a runny nose. Eating fruit has no effect on a runny nose, but you cannot hope to eat fruit to cure a runny nose. Runny nose is a common symptom, which may be caused by allergic rhinitis or upper respiratory tract infection. Fruits are nutrients other than water, including rich vitamins, fats and carbohydrates, etc. Nutrients have no therapeutic effect and cannot relieve the symptoms of runny nose. By the same token, the ingredients in fruits also have no effect on runny nose and will not aggravate the symptoms of runny nose. If the runny nose is caused by allergic rhinitis, some people may be allergic to certain fruits, such as mangoes and grapes, etc. At this time, they should avoid eating fruits that are easy to cause allergy, so as not to induce allergy and aggravate the symptoms of runny nose.
