Patients in the early stages of a cold should avoid eating watermelon.
According to Traditional Chinese Medicine, when the exterior of the body has not yet been relieved, one should not attack the interior, otherwise the condition will worsen. In the early stages of a cold, the pathogen is on the surface of the body. Eating watermelon is equivalent to taking medicine to clear internal heat, which will draw the pathogen inward, worsening the cold or prolonging its course. Patients with weak spleen and stomach, gastritis, enteritis, etc., should not eat too much.
Watermelon is a sweet and cold food. Those with cold accumulation, abdominal pain from cold, or frequent urination should consume it with caution. Eating too much watermelon at once will dilute the gastric juice with its high water content, leading to indigestion and a decrease in gastrointestinal resistance. Eating a large amount of watermelon that has been frozen for too long can also damage the spleen and stomach, or cause pharyngitis.
Patients with diabetes should best avoid eating watermelon.
Watermelon contains a large amount of fructose, which is converted into glucose in the body. Eating watermelon is like drinking sugar water, which will raise blood sugar, increase the burden on the pancreas, raise urinary sugar, and worsen the condition of diabetic patients.
When eating watermelon, one should avoid eating spoiled watermelon or watermelon that has been open for too long. This is because the temperature is high when watermelon is in season, which is suitable for the breeding of bacteria. Eating spoiled watermelon contaminated by bacteria can lead to intestinal infectious diseases.
