In general, patients with pulmonary nodules can eat dried longan, but it is not recommended to consume too much. The specific analysis is as follows:

Patients with pulmonary nodules may consume dried longan in moderation. Dried longan is rich in glucose, vitamins, and essential minerals such as iron and potassium, which help replenish energy and nutrients for the body. With its mild nature, moderate consumption will not irritate the lungs. Since most patients with pulmonary nodules are relatively weak physically, eating an appropriate amount of dried longan can help supplement daily nutritional needs and support physical recovery.

However, intake should be carefully controlled to avoid excessive consumption that may cause internal heat ("fire"), leading to symptoms such as dry mouth and throat discomfort. A light and balanced diet is recommended, including plenty of fresh vegetables and fruits, while avoiding spicy, stimulating, and greasy foods. Additionally, maintaining regular sleep patterns, undergoing routine follow-up examinations, and monitoring changes in the nodules promptly are important for overall management.
