Watermelon – A Brief History
Believed to have originated in South Africa, the watermelon is available in diverse varieties – sweet, bland, and bitter. By the 7th century, watermelons were being cultivated in India. The fruit reached China by the 10th century, and today, the country is the largest watermelon producer in the world.
That’s the brief. Coming to its goodness…
Is Watermelon Good For You?
This juicy fruit that we so lovingly devour in summers is replete with nutrients. It is rich in potassium and vitamins A, C, and B. But what makes the watermelon fruit a must-have is lycopene, the antioxidant that renders the fruit its deep red color.
Numerous studies have supported the beneficial effects of lycopene. The antioxidant is known to reduce the risk of stroke and also lower the blood pressure levels.
It may not have as much fiber as other fruits, but watermelon calories content and fat content is low and contains a lot of water. This was about the importance of watermelon fruit, now have a look at watermelon nutritional benefits.
Watermelon Nutritional Value
|Watermelon (Citrullus lanatus), fresh|
|Nutritional Value per 100 g|
|(Source: USDA National Nutrient data base)|
|Principle||Nutrient Value||Percentage of RDA|
|Total Fat||0.15 g||0.5%|
|Dietary Fiber||0.4 g||1%|
|Pantothenic acid||0.221 mg||4.5%|
|Vitamin A||569 IU||19%|
|Vitamin C||8.1 mg||13.5%|
|Vitamin E||0.05 mg||0.5%|
|Vitamin B6||0.1 mg||3%|
Watermelon is quite low in calories. A single serving of watermelon contains just about 46 calories.
The fruit is replete with vitamins. Two of the major vitamins in watermelon are vitamins A and C. The vitamin A in watermelon is present in the form of carotenoids. Watermelon is also a very good source of vitamin C. A cup of fresh watermelon contains about 12 milligrams of vitamin C.
A cup of diced watermelon contains about 4% of the potassium you would need on a regular basis.
Around 175-200 calories of fresh watermelon gives you 3-4 grams of dietary fiber, which is a nice mix of soluble and insoluble fiber.
A single serving of watermelon contains about 11.6 grams of carbohydrates, which is a combination of dietary fiber, starch, and sugars.
The fruit has very less fat content. A single serving has just about 0.2 grams of total fat.
One of the most important nutrients in watermelon that is responsible for most of its benefits.
Well, that’s about nutritional value of watermelon. Now, let’s see what are the amazing watermelon benefits!
Health Benefits Of Watermelon
1. Keeps Your Heart Healthy
According to research, having a slice of watermelon every day can halt the accumulation of bad cholesterol, thereby preventing heart disease (1). Regular consumption of watermelon has also been linked to fewer fatty deposits inside the blood vessels.
These heart-healthy properties of watermelon can be attributed to citrulline, a chemical found in the fruit. As per a Kentucky study, citrulline can have beneficial effects on atherosclerosis (2). Citrulline has also been found to reduce arterial stiffness in postmenopausal women (3).
2. Helps Treat Inflammation
Another primary compound found in watermelons is lycopene, which has great benefits. In one American study, lycopene was found to exhibit anti-inflammatory properties (4).
Amongst the different carotenoids, lycopene is considered the best (5). In fact, the beneficial effects of lycopene for inflammation are considered even better than beta-carotene, an important carotenoid (6).
3. Keeps You Hydrated
Wondering what percentage of watermelon is water? As the name of the fruit implies, watermelon is 90% water, making it one of the best sources of hydration (7). It is far better than alcohol or caffeine in terms of being a diuretic. As it is a natural source, it increases urination without stressing the kidneys (8).
4. Helps Combat Cancer
Lycopene gets the credit, again. According to a study, lycopene in watermelons has been found to reduce the extent of cancer insurgence (9). Lycopene is the pigment that renders watermelons their characteristic red color, and since it is a powerful antioxidant, it prevents the onset of certain cancers (10).
A two-cup serving of watermelon contains about 20 milligrams of lycopene, which battles free radicals and protects against numerous types of cancer (11). According to a Chicago study, lycopene exhibits chemopreventive properties, especially in prostate cancer cells (12).
Lycopene has also been found useful in the treatment of HPV (human papillomavirus) infection, which might otherwise lead to uterine cancer (13).
5. Might Help Relieve Muscle Soreness
If your sore muscles trouble you after a workout, watermelon might hold the key. The fruit is packed with electrolytes and the amino acid citrulline, which help soothe sore muscles after a heavy workout (14). And as per an Iranian study, citrulline in watermelons can help reduce muscle fatigue (15).
Citrulline has also been externally added to watermelon juice to check its effects, and it has been proven that it is only the naturally occurring citrulline in watermelons that has any effect on muscle soreness (16).
Citrulline has been found to accelerate the process of lactic acid removal, thereby relieving muscle soreness (17). Drinking watermelon juice can also help your muscles receive more oxygen – this helps them recover faster (18).
6. Aids Digestion
Watermelon, as we have seen, contains huge amounts of water, and hence can aid digestion. It also contains fiber, thus promoting digestion and preventing constipation.
7. Is Good For Pregnant Women
Watermelon eases heartburn, a common condition during pregnancy. It also helps alleviate morning sickness (19). The minerals in the fruit can help prevent third-trimester muscle cramps.
Watermelon can be good for pregnant women in other ways as well.
8. Might Prevent Macular Degeneration
As we have seen, watermelons are an excellent source of lycopene – which was found to reduce the risk of macular degenerative disease (20).
According to Mayo Clinic, lycopene has been suggested as a potential treatment for eye disorders like macular degeneration (although further studies are required in this regard) (21).
Antioxidants are essential for eye health as they offer protection against free radicals. The effect of free radicals can be scary – they might lead to the deterioration of the eye lens, and can even cause blindness. Lycopene, being a potent antioxidant, prevents this (22).
9. Prevents Asthma
Hail lycopene, again! Being one of the key antioxidants, lycopene helps with the body’s reaction to cold and flu. And what’s more interesting is this antioxidant has been found to reduce asthma flare-ups in children (23).
Watermelon also allows people who have asthma to breathe properly, without them having to take each breath in panic (24). A study conducted on 17 asthmatic adults showed that lycopene might have a therapeutic effect on the disease (25).
As per a report, adequate intake of lycopene and vitamin A could be beneficial for asthmatic patients (26).
10. Controls Blood Pressure
Watermelon is the richest natural source of citrulline. And according to a study published by the Florida State University, citrulline is closely related to arginine, which is an amino acid essential for maintaining healthy blood pressure (27).
Another study that had volunteers consuming concentrated watermelon juice found increased levels of arginine in them, which was likely to have been converted from citrulline (28).
Watermelon also is a good source of potassium, the nutrient that is known to lower high blood pressure (29). Potassium is also an electrolyte that regulates blood pressure during physical exercise (30).
11. Improves Skin And Hair Health
Watermelon is a good source of vitamin C, the nutrient that is essential for collagen synthesis (31). Collagen keeps your skin supple and strengthens your hair.
The vitamin A in watermelon is another important nutrient that contributes to skin health – it repairs and creates new skin cells. Without the nutrient, your skin would appear dull and flaky.
12. Improves Bone Health
Vitamin C plays a major role here as the nutrient is good for the bones and aids wound healing (34). A Switzerland study suggests that lycopene supplementation can prevent osteoporosis and bone fractures (35).
Vitamin A in watermelons has been linked to bone growth (36).
13. Aids Weight Loss
One of the best watermelon health benefits is that it aids in healthy weight loss too. Yes, given its high water content, watermelon can fill you up for fewer calories (37). Water has also been found to speed up metabolism and flush out toxins and fats, which eventually might contribute to weight loss (38).
One wedge of watermelon has just about 86 calories, less than 1 gram of fat, and no cholesterol. It provides 22 grams of carbs and 5% of your daily fiber requirement, making it a great food for fat burning and weight loss (39).
14. Offers Kidney Support
Though watermelons could be good sources of potassium, the percentage is lower compared to most other foods. This is why it can be good for people suffering from chronic kidney disease (40).
However, in some individuals suffering from chronic kidney disease, the kidneys may not be able to remove the excess potassium from the blood. This can raise potassium levels in the blood and lead to complications.
15. Strengthens Immunity
Watermelon, being rich in vitamin C, strengthens the body’s immune system (41). The fruit also contains vitamin B6 that helps the immune system produce antibodies (42). The vitamin also aids in the formation of red blood cells. The fruit has vitamin A that regulates the immune system and protects it from infections (43).
16. Helps Treat Diabetes
What is the link between watermelon and diabetes? Although watermelon has a high glycemic index, it has a lower glycemic load (the value by which a particular food will raise an individual’s blood glucose levels), and hence is good for diabetics.
In a Nigerian study, watermelon was found to have anti-diabetic properties (44). Another study showed the beneficial effects of watermelon pomace juice – it increases the mass of brown adipose tissue and reduces excess white fat mass, which eventually helps treat diabetes (45).
However, take your doctor’s advice in this regard – as certain small-scale studies have stated otherwise.
17. Can Promote Sexual Health
The amino acid citrulline in watermelon relaxes and dilates the blood vessels and might aid in the treatment of erectile dysfunction (46). Citrulline is converted into arginine, which is a precursor for nitric oxide that helps in blood vessel dilation.
According to an Italian study, oral citrulline supplementation has been found to improve erection hardness in men suffering from mild erectile dysfunction (47).
Watermelon can also act as a natural viagra (48). The ingredients in watermelon, especially the phytonutrients, react with the human body and trigger such reactions.
18. Can Prevent Cell Damage
Watermelon, being rich in lycopene, protects the cells from damage associated with heart disease. Lycopene fights the free radicals and prevents cell damage (49).
19. Prevents Heat Stroke
Given its high water content, watermelon is known to prevent hyperthermia (50).
It has a lot of significance in Chinese medicine as well – watermelon is one of the few fruits that clears heat and relieves irritability and thirst. It also relieves heat exhaustion, for which the outermost layer of the rind is used (51).
20. Promotes Healthy Gums
The vitamin C in watermelon keeps the capillaries and gums healthy (52). The deficiency of vitamin C can cause bleeding gums and gingivitis (inflammation of the gums), and watermelon can prevent these conditions (53).
The vitamin C in watermelon can also kill the bacteria in the mouth that might otherwise lead to gum disease and other gum infections.
21. Boosts Energy Levels
Watermelon is a good source of vitamin B, which is responsible for energy production in your body (54). The fruit is low in calories and high in energy, and it can help you stay active for the better part of the day (55).
Another reason you must have a watermelon to stay at the top of your game is potassium. Potassium is an electrolyte that keeps you from feeling tired after an exhausting day (56).
Watermelon, as we have seen, is not just replete with water – but with great benefits as well. You will be surprise to know interesting facts about watermelon – what we will see now.
Stunning Watermelon Facts

- There are over 1,200 varieties of watermelon (in 96 countries) that are grown across the world.
- Thought tomatoes are the richest in lycopene? Maybe not. Watermelon contains 40% more lycopene than raw tomatoes.
- The Japanese grow square watermelons. They place the growing fruit inside square glass boxes, and the fruit takes the shape of the container as it grows.
- Literary legend Mark Twain loved watermelon and called it the food of angels.

What an amazing frui…vege…frui…well, whatever! The benefits of eating watermelon are incredible. The facts are mind-blowing. And now comes the most important part – how do you buy watermelons and store them? What do you need to keep in mind?
Watermelons – Selection And Storage
- You need to look for a firm and symmetrical watermelon that is free of cuts, bruises, or dents. Any irregular lumps or bumps would mean that the fruit received insufficient amounts of sunshine or water.
- Lift the melon. The fruit must be heavy for its size, which means it is full of water, and therefore, ripe. You can try comparing the melon with another of the same size – the heavier one is what you must go for.
- You need to look for the field spot. This is the spot where the melon sat on the ground in the sun. Hence, the darker the field spot, the better. You will find it on the underside of the watermelon. If the field spot is white or nonexistent, it simply means it was picked too soon (and probably isn’t ripe).
- The perfect watermelon is dark green and looks dull. If the watermelon is shiny, keep it aside.
- In case you are purchasing pre-cut watermelons, choose the pieces with bright red flesh and black or dark brown seeds. Avoid the pieces with white streaks or that have too many white seeds.

- A whole, uncut watermelon can be stored for up to a week in the refrigerator. Ensure you handle the fruit carefully to avoid bruising. Also, make sure you don’t store the fruit below 4 degrees C as doing so can cause chilling injuries to the fruit.
- You can cut the watermelon as you usually do. Simply run the blade of the knife down the sides of the fruit. This will cut the rind from the flesh. Cut the watermelon into round disks, and then cut the disks into 1-inch cubes. If you are not consuming it immediately, you can place the cut watermelon in a covered container and refrigerate for up to 3-4 days.
