As a common respiratory disease, bronchitis not only affects patients' respiratory health but also imposes certain dietary requirements.

Among various foods, fruits are considered a healthy choice by many due to their rich content of vitamins and minerals.

However, for patients with bronchitis, extra caution is required when selecting fruits to avoid potential allergic reactions or symptom exacerbation.

Fruits are rich in various vitamins, and these nutrients play important roles in controlling inflammation and participating in airway repair. Therefore, moderate fruit consumption is beneficial for bronchitis patients, with the key being choosing fruits that don't trigger allergic reactions.

For example, fruits like mangoes, peaches, lychees, and longans contain special alkaloids that may induce allergic reactions in patients, leading to worsening airway spasms.

Thus, when selecting fruits, patients should be mindful of their allergy history and try to avoid consuming these potentially allergenic fruits.

From the perspective of Traditional Chinese Medicine, patients with bronchitis should also consider the nature of their phlegm and physical condition when selecting fruits.

Yellow phlegm (phlegm-heat accumulation in lungs): These patients should avoid consuming warm-natured fruits such as durian and tangerines, as these fruits may increase phlegm production and hinder disease control.

Cold phlegm lodging in lungs: Patients presenting with clear/thin phlegm and aversion to cold should limit intake of cold-natured fruits like watermelon. Excessive consumption may lead to spleen deficiency, thereby exacerbating symptoms of phlegm-dampness accumulation in lungs.

When trying new fruits, patients should monitor their physical reactions. Symptoms like dyspnea (difficulty breathing) or skin itching should prompt immediate discontinuation of consumption and medical consultation.
