According to experts from the Johns Hopkins Health System (USA), watermelon contains a lot of water, vitamin C and lycopene, antioxidants that are beneficial for the heart and skin. However, the nutritional quality of watermelon can be reduced if the fruit is spoiled or stored improperly.
Experts advise buyers to observe the bottom of the watermelon. If the bottom is cream yellow or dark yellow, this is usually a sign that the watermelon has naturally ripened in the field. Fruits with a light white bottom are often not ripe enough.
In addition, the watermelon skin should be uniformly green, slightly rough and have a balanced shape. When gently tapping the fruit with your hand, delicious watermelon usually emits a deep and firm sound. If the sound is too sharp or hollow, the watermelon may be young or porous inside.
According to the US Food and Drug Administration, consumers also need to pay attention to hygiene when using watermelons. Although the inner core is protected by a thick skin, external bacteria can still stick to knives and spread to the flesh of the fruit when cut.
Therefore, watermelons should be washed thoroughly under running water before being cut. For pre-cut watermelons, people should only choose products that are properly refrigerated to limit the risk of infection.
Experts also recommend not eating too much watermelon in a short time, especially in the evening, as it can cause bloating or increase blood sugar in people with underlying conditions.
