Patients with acute upper respiratory infections display various clinical symptoms due to differences in the immune function of their bodies. If some patients with upper respiratory infections show only symptoms such as nasal congestion, runny nose, and sneezing, without fever or cough, they can eat mangoes. Mangoes are highly nutritious and can enhance the immune system and also have anti-cancer properties because they contain a high amount of Vitamin C, often more than other fruits, especially when fresh. Eating mangoes can strengthen the immune system, aiding in the recovery from symptoms of upper respiratory infections. However, it is generally not recommended to eat mangoes when acute upper respiratory infections involve fever and cough, as mangoes are tropical fruits and might exacerbate coughing symptoms in some patients.
