It is not suitable to eat in the early stage of a cold

Traditional Chinese medicine believes that no matter it is a wind-cold cold or a wind-heat cold, its early stages are all external symptoms and should be treated with a dispersing treatment method that allows the pathogenic factors to be eliminated from the surface. It is also believed that attacking the cold before the exterior is resolved will aggravate the condition, and watermelon has the effect of clearing heat, so eating watermelon at this time will aggravate the cold or prolong the course of the disease.

Eating watermelon immediately after exercise, especially chilled watermelon, can replenish lost water, but it can easily irritate the digestive tract and damage gastrointestinal health.

Moreover, eating a large amount of watermelon before meals will take up stomach volume, which greatly reduces the intake of multiple nutrients during the meal, especially for the health of children, pregnant women and nursing mothers.
