Watermelon is one of the most beloved fruits of the summer season. Its juicy, refreshing taste and high water content make it a perfect choice for hot days, keeping both kids and adults hydrated and satisfied. However, while watermelon may seem like a simple and harmless fruit, there are important things to look for before eating it. In fact, there’s one warning sign that should never be ignored. If you cut open a watermelon and it looks a certain way, it’s best to throw it out immediately. Knowing what to look for can protect your health and ensure you’re getting the best quality fruit possible.
When buying a watermelon, you can’t always tell what you’re getting just by looking at the outside. That’s why it’s important to understand a few key indicators before making your purchase. First, check the shape and weight of the watermelon. A ripe and healthy watermelon should feel heavier than it looks, indicating that it’s full of water. The shape matters too—avoid irregular or asymmetrical melons and instead go for those with a consistent, oval or round shape. Uneven melons may not have developed properly and could have poor texture or taste.
Next, examine the field spot. This is the area where the melon sat on the ground while ripening. A creamy yellow spot suggests it was allowed to ripen naturally in the sun. If the field spot is white or green, that’s a sign the fruit may have been picked too early and isn’t ripe. Additionally, the melon’s skin should be smooth and shiny, not dull or wrinkled. Some people also use the tapping method—tap the melon with your fingers and listen. A ripe watermelon will sound hollow.
One major red flag is the presence of large internal cracks in the flesh of the melon. If you cut into a watermelon and notice deep splits or hollow areas inside, do not eat it. These cracks often indicate that the melon may have been grown with chemical growth accelerators or artificial fertilizers. Some farmers use these methods to speed up growth or increase size for market appeal, but they can compromise the safety and nutritional value of the fruit. Cracked melons are more than just unappetizing—they could be potentially harmful if exposed to synthetic chemicals during cultivation.
On the flip side, watermelon offers numerous health benefits when it’s grown naturally and eaten fresh. Not only is the red, juicy flesh packed with vitamins and hydration, but the seeds and rind also provide surprising health perks. Watermelon seeds are particularly nutrient-dense. Just 150 grams of dried watermelon seeds contain around 30.6 grams of protein—roughly 61% of the recommended daily intake. These seeds also provide essential amino acids like tryptophan, glutamic acid, lysine, and arginine, which supports blood pressure regulation and reduces arterial tension.
Niacin, a B vitamin that helps with digestion, nervous system function, and maintaining healthy skin, is another nutrient found in watermelon seeds. They also contain other important vitamins such as thiamine, riboflavin, B6, and pantothenic acid. On the mineral side, watermelon seeds are rich in magnesium, phosphorus, iron, potassium, sodium, copper, manganese, and zinc—all of which help support strong bones, joint function, and overall metabolic health.
The watermelon rind, particularly the white part near the peel, contains citrulline—an amino acid known to help the liver eliminate ammonia, a waste product. Citrulline also aids in expanding blood vessels, boosting energy levels, and reducing oxidative stress in the body. It’s a hidden nutritional powerhouse that most people toss in the trash without a second thought.
The fruit itself contains high levels of antioxidants and immune-boosting compounds. It’s rich in vitamins A, C, D, E, B6, and B12, along with key minerals like iron, calcium, magnesium, potassium, phosphorus, zinc, and selenium. These nutrients play a crucial role in supporting heart health, reducing inflammation, and preventing certain types of cancer, including colon, prostate, breast, and cervical cancers.
One standout antioxidant found in watermelon is lycopene. This compound is responsible for the fruit’s red color and is known for its powerful ability to combat free radicals. Interestingly, watermelon contains more lycopene than tomatoes, making it a superior choice for those looking to reduce bad cholesterol, prevent cataracts, protect against cardiovascular disease, and even improve bone health.
In summary, while watermelon is an incredibly healthy and hydrating fruit, it’s important to be cautious when selecting and preparing it. Always inspect for visual signs of freshness, check the weight and shape, and most importantly, watch for internal cracks. If you spot deep splits inside the melon, discard it immediately—it may be a sign of chemical contamination. By following these simple tips, you can enjoy the full benefits of watermelon without compromising your health.
