Cold and flu patients can usually eat loquat, but need to eat in moderation. Colds are infectious diseases of the upper respiratory tract caused by viral infections, which are mainly characterized by symptoms such as nasal congestion, runny nose and cough. If the symptoms are mild, generally no medication is needed, and the symptoms can be relieved by general treatment, such as paying attention to rest, eating a light diet, and avoiding exertion. In case of influenza caused by influenza virus, antiviral drugs such as oseltamivir should be used at an early stage. Loquat is a kind of food, which is rich in sugar, protein, fruit acids, vitamins, carotene, crude fiber, minerals and other nutrients, which can replenish the nutrients needed by the human body and maintain the normal physiological function of the body. Therefore, patients with colds can eat loquat. Because loquat contains a lot of sugar, may stimulate the throat to aggravate cough symptoms, it is recommended to eat in moderation. In addition, diabetic patients can increase blood sugar after consumption, so it is recommended that diabetic patients eat a small amount to avoid aggravating their condition. If the symptoms of cold and flu are more serious, it is recommended to consult a doctor in time and standardize the treatment under the doctor’s guidance to avoid delaying the condition. Patients can eat more fresh vegetables and fruits in their daily life, and increase the amount of exercise appropriately, which will help to enhance the immunity.
