Can I eat watermelon if I have gastrointestinal discomfort during a cold?
Generally speaking, it is okay to eat watermelon during a cold if experiencing gastrointestinal discomfort, but the quantity should be controlled. Detailed explanations are as follows:

Watermelon has a high water content, which can help replenish fluids lost due to a cold. It is also rich in dietary fiber, vitamins, and other nutrients, especially vitamin C, which helps strengthen the immune system to fight cold viruses. Additionally, eating watermelon can help relieve heat and alleviate symptoms such as thirst and sore throat caused by a cold.
However, watermelon is a cold-natured fruit, and excessive consumption may cause gastrointestinal discomforts such as diarrhea and abdominal pain. Therefore, its intake should be moderated to avoid overconsumption. At the same time, one should avoid consuming overly cold, greasy, or strongly stimulating foods, such as ice cream, chili peppers, and coffee, to prevent additional stress on the gastrointestinal tract.
During a cold, it is recommended to choose light and easily digestible foods, such as porridge or boiled noodles, which can help restore gastrointestinal function. Seek timely medical attention when necessary to receive targeted treatment.
