Can I eat cold or cool fruits while taking medication?
Generally, it is not recommended to consume cold-natured fruits while taking medication. The specific reasons are as follows:
Cold-natured fruits, such as watermelon and bananas, may cause cooling effects in the body, potentially affecting the normal absorption of medications. Additionally, these cold fruits might increase the burden on the gastrointestinal system, reduce the effectiveness of the medication, and hinder the recovery from illness. For example, the diuretic effect of watermelon may increase urine output, causing the medication to be excreted more quickly from the body, thereby reducing its effectiveness. Hence, it is generally not advisable to consume cold-natured fruits while taking medication.

To ensure safety, it is recommended to consult a doctor or pharmacist for advice while taking medication, to understand potential interactions between the medication and food. Additionally, paying attention to your own constitution and health condition and making appropriate dietary choices can help promote recovery from illness.
In daily life, it is also recommended to maintain a balanced diet with appropriate intake, while observing your body's responses to avoid excessive consumption or eating when it is unsuitable.
