Watermelon is undoubtedly one of the most beloved fruits, especially during hot weather. It is refreshing, naturally sweet, and packed with water, vitamins, and quick energy. Because it is made up mostly of water, watermelon also acts as a natural diuretic, helping the body eliminate excess fluids.

On hot days, when temperatures rise above 30°C, enjoying a slice of watermelon can be extremely satisfying. It helps cool the body, supports hydration, and provides a light source of natural sugars that can boost energy without feeling heavy.

This fruit is often recommended for its many health benefits. It is widely available, affordable, and convenient. Another advantage is that a whole watermelon can remain fresh for several days if stored properly.

However, watermelon is not always as harmless as it seems. Despite its healthy reputation, there are certain risks associated with it that can lead to health problems if ignored.

Although it may sound surprising, watermelon can sometimes cause serious issues when its quality is compromised. Understanding how to recognize warning signs can help you avoid potential danger and protect your health.

For example, when you cut open a watermelon, you might occasionally notice large cracks or hollow gaps inside the flesh. Many people ignore this and continue eating it, assuming it is harmless. In reality, this could be a sign of a chemical growth agent called forchlorfenuron, which may have been used to speed up the fruit’s growth.

Watermelons with internal cracks should be avoided. These cracks can indicate that the fruit developed too quickly due to artificial growth stimulants. Forchlorfenuron is a plant growth regulator sometimes sprayed on watermelons to increase size and speed up ripening.

The main concern with forchlorfenuron is its potential impact on human health. When it accumulates in the body, it may increase the risk of cancer and neurological problems, which are difficult to detect and treat early. Although not all cracked watermelons contain this chemical, the visual sign should be treated as a warning signal.

How to Keep Watermelon Fresh

If you do not plan to eat a watermelon immediately, proper storage is essential to maintain its quality and safety.

First, selecting a good watermelon makes a big difference. Look for the following signs:

• A firm and smooth rind

• A yellow ground spot (where the watermelon rested on the soil)

• Heavy weight for its size

• A hollow sound when tapped

• Clear surface stripes spaced about two finger-widths apart

These features usually indicate ripeness and good internal quality.

Once you have chosen a watermelon, it is best to keep it whole until you are ready to eat it. Whole watermelons stay fresh longer than cut ones. Storing it in a cool place slows down the ripening process. While it can be kept on a kitchen counter away from sunlight, placing it in the refrigerator will extend its freshness even further.

After a watermelon is cut, it loses freshness much more quickly. To preserve it, refrigerate it immediately. Wrap the pieces tightly in plastic wrap or place them in an airtight container before storing them in the fridge. This prevents moisture loss and reduces the risk of bacterial growth.

Keeping both whole and cut watermelon chilled helps preserve its flavor, texture, and nutritional value for as long as possible.

Final Thoughts

Watermelon is a delicious and hydrating fruit that offers many health benefits, especially during summer. However, it is important to inspect it carefully before eating. Watermelons with unusual internal cracks should be avoided, as they may be linked to artificial growth chemicals.

By choosing quality fruit and storing it correctly, you can enjoy watermelon safely while minimizing potential health risks. Like all foods, it is best consumed in moderation and with attention to freshness and appearance.
