Watermelon is one of my favorite fruits of all time. It is highly cleansing, alkalizing and mineralizing – excellent for flushing the kidneys and bladder, curing and preventing a wide range of ailments.

Watermelon is a member of the Cucurbitaceae family that includes fruits such as melon, pumpkin and similar plants that grow on the ground on vines.

Watermelons can be round, elongated or spherical; light to dark green in color, with lighter speckled stripes.

The juicy flesh is usually bright red in color, but there are also other varieties with dark brown, orange, yellow, pink and even white meat.

Watermelon Nutrition Data

The water content in watermelon is extremely high at 92%. It is rich in beta-carotene, folate, vitamin C, vitamin B5 and smaller amounts of B1, B2, B3 and B6.

This large fruit is a rich source of essential minerals such as calcium, magnesium, phosphorus, potassium, sodium and smaller amounts of copper, iron and zinc.

Just like tomatoes, watermelon is full of lycopene, the red carotenoid pigment that gives the fruit its red color. This important antioxidant is powerful in neutralizing harmful free radicals in our body.

Perhaps one of the most important compounds in watermelon is citrulline. Read on for more information about what citrulline can do for your body.

Health benefits of watermelon juice

Watermelon juice is very cleansing, alkalizing, diuretic and mineralizing.

Watermelon is so rich in vitamins, minerals, enzymes and phytonutrients. The advantage of drinking watermelon juice is that it is easily digestible and that the nutrients are quickly absorbed by your body at the cellular level.

Utilizing the rich antioxidant and beta-carotene, the health benefits of watermelon are huge.

Eating foods that are highly acidic causes your blood to become acidic, potentially lowering your immune system and increasing the chance of developing a chronic disease.

The key to controlling and preventing diseases is then creating an alkaline environment in your body. Because of the high water content, watermelon has a very basic pH, making it an excellent food for reversing the symptoms of acidosis (over-acidification).

Harmful pathogens – parasites, harmful bacteria, viruses, fungi and yeasts – thrive in an acidic body, while an alkaline environment neutralizes the toxic state and prevents cell damage and aging.

Watermelon has a water content of 92% and is rich in electrolytes, making it excellent againmoisturize food. This is important, such as thehydration ensures that the body is acidic.

  • Reduces inflammation in the body

Recent studies have found that watermelons have 1.4x the lycopene content of tomatoes compared to the same volume.

Lycopene is the phytonutrient in the fruit that gives it its red-pink color. And in watermelon this antioxidant is available in abundance.

Unlike tomato lycopene that needs to be processed for the best bioavailability, watermelon lycopene is immediately available to the human body after consumption. What this means is that no processing of the watermelon is needed to enjoy the benefits of lycopene.

Thanks to lycopene and other powerful nutrients in watermelon juice, they work as inhibitors for various inflammatory processes. Reducing inflammation provides relief and healing to people suffering from body and muscle pain and various forms of arthritis.

  • Protects against asthma and allergic attacks

The presence of high concentration of lycopene in watermelons, plus the easy bioavailability, helps reduce oxidative stress and inflammation in case of asthma and allergies.

Several studies reported lower rates of wheezing and allergic rhinitis in children who consumed antioxidant-rich foods such as watermelon.

Oxidative stress as a result of excessive free radicals in the body, can have a harmful effect on the airway function and cause asthma and allergy attacks. In this case, the consumption of watermelon juice helps to increase immune responses in preventing attacks.

The arthritis.org website agrees that watermelon is beneficial for people suffering from various forms of arthritis.

Studies show that watermelon can lower C-reactive protein (CRP) – a measure of body-wide inflammation associated with arthritis and heart disease.

Watermelon is rich in carotenoid beta-cryptoxanthin, which is beneficial for people suffering from rheumatoid arthritis and reducing painful inflammatory conditions.

  • Treats disorders in the kidney system

Of all fruits, watermelon has the highest amount of amino acid citrulline, a word derived from citrullus, a Latin word for watermelon. This compound is found in the highest concentration in the white skin (the white substance just below the skin).

That is why it is useful to add the zest when making watermelon juice, especially if you have kidney or bladder problems.

High concentrations of citrulline and vitamin C (ascorbic acid) in watermelon rind juice help break down kidney stones, clean the kidneys and bladder and reduce inflammation caused by free radicals.

The citrulline in watermelon is also important to make this fruit richly moisturizing and naturally moisture-repellent. The natural diuretic effect ensures that your kidneys and bladder are effectively flushed with toxins, reducing fluid retention in the body.

Ladies who have PMS problems with water retention may find relief when drinking watermelon juice a week prior to their period, and also prevent bloating.

Start with the first sign of a urinary tract infection (UTI) freshly extracted watermelon juice – meat, seeds, zest and everything – until the symptoms have disappeared.

  • Calms the gastrointestinal tract

Like most fruits, watermelon juice has a natural laxative effect that helps improve regularity for a healthy digestive system.

Watermelon juice helps to calm the gastrointestinal tract, regulates the pH, reduces inflammation and acidity. This makes it an excellent, healing drink for people suffering from acid reflux.

Watermelon juice is one of the best juices to drink when you are hidden. If you have chronic constipation, make sure you drink a glass of watermelon juice daily to improve regularity. This is especially useful for children with constipation – most children love watermelon juice and it is easy to make them drink it.

To relieve that occasional constipation, drink a large jumbo glass of watermelon juice (about 20-30 ounces) on an empty stomach.

  • Gives electrolytes to your body

Watermelon juice is rich in various minerals (calcium, magnesium, potassium, sodium and phosphorus) to replenish electrolytes that have been lost after proper training.

If you have any of these symptoms, chances are that you have a disturbed electrolyte balance: muscle aches, spasms, muscle twitches and weakness; restlessness, frequent headache, insomnia, palpitations, tiredness, numbness and pain in joints and dizziness.

Consistently drink watermelon juice every day to provide your body with these rich minerals until your symptoms disappear.

Watermelons contain a lot of beta-carotene (pro-vitamin A) that is converted in your body into vitamin A (retinol).

If you have read that vitamin A is toxic at high levels, this only refers to additional sources (synthetic) and does not apply here. Dietary sources (natural foods) of vitamin A are not toxic at all, not even in large quantities.

Beta carotene is the red pigmentation that gives watermelon meat its color. It is an antioxidant that protects your eyes against damage caused by free radicals.

One of the main causes of eye problems is due to a low intake of antioxidants and vitamin A in the diet. So it makes sense that when you flood your system with watermelon juice (or other high-antioxidant juices) that are rich in these compounds, they help nourish and improve your eye health.

Vitamin A is essential for good vision, and it protects your eyes from various eye problems such as age-related macular degeneration, cataracts, retinal degeneration, night blindness and the like.

  • Lowers the risk of strokes and heart attacks

The health benefits of watermelon are simply endless. The combination of high antioxidants, lycopene and other essential vitamins and minerals in this fruit plays an important role in reducing the risk of heart attacks and strokes.

Studies show that the rich nutrients in watermelon, along with lycopene, are health-promoting agents that reduce the risk of cardiovascular disease.

It has been observed that a high consumption of lycopene in watermelon reduces the thickness of the internal layer of blood vessels, thereby reducing the risk of a heart attack.

Risks of heart attacks, ischemic strokes and artheroslerosis are also greatly reduced when oxidation of LDL is prevented by drinking watermelon juice.

The diuretic effect of watermelon juice flushes toxins and excess salt from your body. This process ensures that the walls of your blood vessels relax and widen, thereby improving blood flow and lowering blood pressure. This can even be observed after drinking just one glass of watermelon juice.

  • Removes toxic waste from your body

Watermelon is one of the best fruits that are included when cleaning juice. Alternatively, you can only do a watermelon detox because it is effective for removing toxic waste from your body that slows down your metabolism.

When toxins are eliminated, it goes without saying that your largest organ, your skin, has a healthy glow. You can expect clearer, smoother skin that is well hydrated.

Persons suffering from itching on the skin due to acidosis toxicity may also find relief after a detox of watermelon juice.

  • Protects against various types of cancer

Watermelon is a valued source of natural antioxidants with special reference to its lycopene, ascorbic acid and citrulline. These compounds have been shown to act as protection against chronic health problems such as cancer.

In fact, watermelon has the highest concentration of lycopene of all fresh fruit or vegetables. Lycopene has been extensively researched due to its antioxidant and cancer preventative properties.

It is reported that it is primarily protective against prostate, lung, colorectal, endometrial and breast cancer.

As discussed above, watermelon juice relaxes and drinks your blood vessels and increases your overall energy and endurance. This works well for both athletes and men who need extra energy in bed!

Watermelon acts as a natural viagra, according to an Italian study. It has been found that consuming watermelon juice with a high content of citrulline improves erection hardness in men with mild erectile dysfunction.

In the study, men with mild erectile dysfunction (erection hardness score 3) received L-citrulline supplementation for one month. L-citrulline is the natural form of citrulline.

50% of the men appeared to have an improvement in erection hardness score from 3 (mild ED) to 4 (normal erectile function), with no adverse effects.

The number of private parts per month increased and all participants indicated that they were very satisfied with the treatment.

Like all fruit and vegetables, watermelon has very few calories. Consumption of 100 grams of watermelon yields approximately 30 kcal. It contains almost 92% water and 7.55% carbohydrates, including 6.2% sugars and 0.4% dietary fiber.

Eating watermelon or drinking its juice is very satiating and fulfills your body's need for all the nutrients it needs. You feel full longer.

And because watermelon helps keep your gastrointestinal tract healthy, prevents constipation, water retention and bloating and removes toxins from the body – these all contribute to gradual weight loss.

As your body becomes healthier, weight loss often comes naturally.

Watermelon for people with diabetes mellitus (type 2)

Experimental studies have shown that patients with high blood sugar levels (hyperglycaemia) are more susceptible to risk of coronary complications. Increased oxidative stress and LDL oxidation are important factors that contribute to this.

As discussed above, watermelon juice is excellent in combating both of these conditions: oxidative stress and LDL oxidation.

Lycopene in watermelon has the potential to reduce oxidized cholesterol in the diabetic state. It has the ability to lower glucose in the body and to increase insulin levels in type 2 diabetes.

In one study, watermelon extract was administered to diabetic rats. At the end of the study, a 37% increase in insulin level was observed, while a 33% drop in glucose was observed. The study concluded that watermelon extract is a hyperinsulinemic and hypoglycemic product.

So, can you get watermelon if you have diabetes?

The answer depends on your overall diet. If you generally pay attention to your diet and eat foods that are usually low in sugar, it would not hurt to eat watermelon, or even drink watermelon juice in moderatioin. Here are a few tips:

Although watermelon extract may not be readily available (per study above), opt for people with diabetes – choose watermelons that are less ripe. This article tells you how to pick ripe watermelons, the contrasts are true for picking unripe watermelons.

The flesh of a less ripe watermelon is light pink, not red, and has a low sugar content.

Wash the watermelon clean, incorporate the watermelon skin and skin into your juice to enjoy the full benefits of kidney cleansing.

Health benefits of watermelon seeds

Eating a small amount of watermelon seeds can give you the chance to enjoy the many nutrients and benefits.

Watermelon seeds are packed with healthy fats. These fats can reduce your appetite, help you feel full and strengthen your hair, skin and nails.

Watermelon Consumption tips

So the question is: is eating too much watermelon bad for you?

Although watermelon is great and beneficial for all the health issues we discussed above, eating too much anything in the long term can have an adverse effect.

However, it is fine to eat watermelon or drink the juice for a season, therapeutically, depending on the severity of your health condition.

Here are some tips on preparing and consuming watermelon.

  • The best time to eat watermelon or drink its juice is on an empty stomach earlier in the day. Drinking watermelon juice later in the night can cause you to urinate when you sleep, which disrupts your sleep.
  • Watermelons grow on the ground, so wash thoroughly before cutting to prevent contamination.
  • If you can't finish a whole watermelon, wrap it with a cling film and keep it cool to preserve freshness and prevent it from drying out. This also prevents it from absorbing odors from other foods in the refrigerator.
  • Watermelon can be eaten alone, in fruit salads or juice. You can also freeze pureed watermelon in ice cube trays. Kids love this, especially on a hot day! You could try a watermelon and kiwi popsicle.
  • Watermelon peel contains 95% of the nutritional value and can be pressed together with the seeds.
