Watermelon: green on the outside, red on the inside — and full of benefits

Fresh, sweet, refreshing. Watermelon is not just a berry (although botanists insist on this definition), it is a symbol of summer, picnics, childhood, and carefree pleasure. But behind its bright appearance and pleasant taste lies a real treasure trove of useful substances. It does not just quench thirst on a hot day — it takes care of our heart, skin, muscles, and even mood. In this article, we will understand why watermelon deserves to be on our table not only as a dessert but also as an important element of a healthy diet.

Short history: from the Kalahari Desert to the whole world

The birthplace of watermelon is the Kalahari Desert in South Africa. Wild varieties of this plant, which, by the way, are not sweet and bitter in taste, are still found there. About five thousand years ago, watermelons began to be cultivated in Ancient Egypt. Images of watermelons can be found on the walls of tombs, and seeds of this plant were even found in the tomb of Tutankhamun. From Egypt, watermelon spread to Asia, and then, thanks to Arab traders, to Europe. In Russia, it appeared in the 13th-14th centuries and quickly became popular for its ability to quench thirst in the hot summer. Today, watermelons are grown almost in all warm regions of the world, and breeders have bred hundreds of varieties — from giant to miniature, from classic red to yellow and even white.

What's inside: the nutritional composition of watermelon

The main thing to know about watermelon is that it consists of water almost 92%. This makes it an ideal drink that you can also eat with a spoon. However, the other 8% are not just \"empty\" calories. In this small amount, there is an impressive set of vitamins, minerals, and bioactive compounds.

• Vitamin C: a powerful antioxidant, necessary for immunity and skin health.
• Vitamin A: important for vision, cell growth, and maintaining skin and mucous membrane health.
• Vitamins of the B group, especially B6: play a key role in metabolism and the functioning of the nervous system.
• Potassium: an electrolyte that regulates water balance, heart function, and muscle contractions.
• Magnesium: involved in hundreds of biochemical reactions, helps cope with stress.
• Lycopene: a powerful antioxidant that gives watermelon its red color and has numerous beneficial properties.
• Citrulline: an amino acid that improves blood circulation and lowers blood pressure.

It should be noted that the calorie content of watermelon is not high — about 30-40 kcal per 100 grams. This makes it an excellent option for those who are watching their weight.

Health benefits: science and tradition

Hydration and kidney health

Thanks to its high water and potassium content, watermelon is a natural diuretic. It helps the kidneys excrete toxins, prevent the formation of stones, and maintain normal water balance. Moreover, unlike many other products, watermelon does not burden the digestive system and is easily digestible, providing the body with moisture without a feeling of heaviness. On a hot day, a few pieces of watermelon can replenish fluid loss more effectively than a glass of water.

Heart and blood vessels

One of the most impressive abilities of watermelon is to take care of the cardiovascular system. Citrulline, contained in watermelon, is converted into arginine — an amino acid that promotes the expansion of blood vessels and improves blood flow. This helps to lower blood pressure, reduce the risk of heart attack and stroke. Lycopene, in turn, protects blood vessels from oxidative stress, slows down the development of atherosclerosis, and maintains the elasticity of blood vessel walls.

Muscles and recovery after exercise

It's no coincidence that watermelon juice is becoming increasingly popular among athletes. Citrulline not only improves blood circulation but also reduces muscle pain after intense physical exertion. Studies show that drinking watermelon juice before or after exercise accelerates recovery, reduces the level of lactic acid in muscles, and improves overall endurance. So watermelon is not just a dessert but a real natural sports drink.

Skin and vision

Vitamins A and C make watermelon an ally of beautiful and healthy skin. Vitamin C stimulates the production of collagen, which is responsible for the elasticity and firmness of the skin, prevents the formation of wrinkles. Vitamin A, in turn, protects the skin from harmful ultraviolet radiation and promotes cell renewal. Moreover, beta-carotene contained in watermelon is important for eye health, especially in conditions of bright sunlight.

Immunity and fighting inflammation

Lycopene is a powerful weapon against free radicals. It has anti-inflammatory properties, protects cells from damage, and even reduces the risk of developing certain types of cancer, especially prostate cancer. Vitamin C, in turn, actively supports the immune system, helping the body fight viruses and infections. During the flu and virus season, watermelon is no less useful than common lemons and ginger.

Myths and truths about watermelon

Watermelon is associated with many myths. One of the most widespread is that it contains a lot of sugar. In fact, the glycemic index of watermelon is quite high, but the glycemic load, that is, the actual impact on blood sugar levels, is low due to its high water content. Eating watermelon in reasonable amounts is not dangerous even for people with diabetes, although, of course, it is worth consulting a doctor.

Another myth is that watermelon contains nitrates that can harm health. Indeed, dishonest producers may use chemical fertilizers to accelerate growth. However, the content of nitrates in a quality, ripe watermelon is minimal and does not pose a threat. To ensure safety, it is worth choosing watermelons in season (August-September), buying them in trusted places, and not eating the flesh all the way to the rind.

And finally, the famous myth that watermelon should not be eaten at night due to its diuretic effect. Yes, watermelon does have a diuretic effect, and if you have a sensitive bladder, it is better not to eat it right before bedtime. However, in moderate amounts, it will not cause discomfort and will bring much more benefits.

How to choose and store watermelon

Picking a good watermelon is an art. Experienced buyers recommend paying attention to the following signs:

• Sound: a ripe watermelon makes a dull, not a ringing sound when tapped.
• Shell: it should be firm, shiny, without cracks and soft spots.
• Yellow spot: on the side on which the watermelon lay on the ground, there should be a yellow or orange spot — a sign that it ripened in the sun.
• Stalk: a dry stalk indicates that the watermelon has ripened and was picked at the right time.

It is better to store a whole watermelon at room temperature for up to three weeks. Cut watermelon should be immediately placed in the refrigerator and eaten within a day, otherwise it loses its useful properties and can become dangerous.

Not just food: watermelon in cosmetology

Watermelon is useful not only when consumed internally but also externally. Watermelon juice is used in homemade facial masks — it moisturizes, tones, and lightens the skin. The vitamins and antioxidants contained in it help fight the first signs of aging, soothe irritated skin, and give it a healthy glow. To make a simple mask, just mix a little watermelon juice with oatmeal flour or yogurt. But, of course, watermelon works best from the inside.

Conclusion: a berry that takes care of us

Watermelon is not just a delicious treat. It is a natural cocktail of vitamins, antioxidants, and essential minerals. It takes care of our heart, blood vessels, kidneys, muscles, and skin, helping us stay healthy and energetic, especially in the hot season. It is affordable, cheap, and brings genuine pleasure to everyone who tries it. And if you haven't included watermelon in your diet yet, maybe it's time to do so. Because, besides sweetness, it gives us something that cannot be bought — care for health and good mood.
