Can watermelon be eaten in summer?

Whether watermelon can be consumed in summer depends on one’s individual health condition.

Watermelon contains abundant water as well as essential nutrients such as vitamins and amino acids. Consuming it helps replenish both fluids and nutrients in the body. Especially during summer, moderate intake of watermelon can help clear internal heat and relieve summer-heat syndrome, thereby reducing excessive “fire” (a traditional concept referring to inflammatory or hyperactive conditions) in the body and preventing heatstroke. For individuals in good health, watermelon is generally safe to eat in summer—but only in moderation. As a cold- and cool-natured fruit, excessive consumption may adversely affect the gastrointestinal tract.

Individuals with diabetes should avoid watermelon not only in summer but throughout the year, due to its relatively high sugar content—primarily rapidly absorbable sugars like glucose—which may cause blood glucose levels to rise and hinder glycemic control. Additionally, patients with impaired renal function should also avoid watermelon, as its high water content may exacerbate their condition.
