Watermelon Health Benefits Are Amazing

A big piece of watermelon is a delicious and refreshing treat on a hot day and you will get all the watermelon health benefits.  I love watermelon and can easily eat a quarter of one in one sitting!

Yes, watermelon is 92% water but that other 8% is filled with good nutrition and amazing health benefits; so many benefits that we consider it a very healthy superfood.  Watermelon health benefits range from reducing cancer to having a viagra effect.

Watermelon Health Benefits 

1.  Watermelon may help reduce cancer risk.  Watermelon is the lycopene leader of fresh fruits and vegetables. The lycopene king tomato has been replaced with deep red varieties of watermelon.  The red pigment is also found in tomatoes, watermelon, apricots, pink grapefruit, and papaya and is an important antioxidant.  It has been found to be helpful in reducing the risk of prostate, breast, and endometrial cancers, as well as lung and colon cancer according to research.  Lycopene’s ability to neutralize singlet oxygen radicals was better than the antioxidant abilities of beta-carotene and vitamin E.  – From Archives of Biochemistry and Biophysics in 1989.

2. Watermelon is a natural diuretic and was a homeopathic treatment for kidney patients before dialysis became widespread. Now wouldn’t that be better?


3. Watermelon may have Viagra-like effect: they contain citrulline which can trigger the production of a compound in the body that helps relax the body’s blood vessels, in a way similar to what happens when a man takes Viagra according to scientists in Texas.

4. Watermelon is alkaline-forming in the body.  Find out the health benefits to an Alkaline body here:  Balance Your Body

5. Helps muscle and nerve function, being a very good source of potassium. Can ease inflammation that contributes to conditions like asthma, atherosclerosis, diabetes, colon cancer, and arthritis.

6. Watermelon is a certified heart-healthy food by the American Heart Association.

7. Diabetes and Watermelon 

This is what the Mayo Clinic says:

Question: Can diabetics eat watermelon? Can eating watermelon increase blood sugar?

Answer: Diabetics SHOULD eat fresh fruit. And “You’d have to eat a lot of watermelon to significantly raise your blood glucose level.”

Learn more at the Mayo Clinic.

“When one has tasted watermelon, he knows what angels eat.” Mark Twain

I am thrilled to know all the benefits of this favourite summer fruit of mine.  Watermelon is often all I have for breakfast and it always amazes me that I feel full for hours afterward.

It is also true that watermelon is high in sugar with 10 grams per 1 cup of watermelon but think about it.  What is a better choice a candy bar or a piece of watermelon with all its nutrition and watermelon health benefits?

Is it a fruit or a vegetable?

Did you know that some consider Watermelon a vegetable?  It is related to the squash and pumpkin family and is grown as a vegetable crop, using vegetable production systems.

“Watermelon is the fruit of a plant originally from a vine of southern Africa. Like the pepper, tomato and pumpkin, it is the ripened ovary of a seed plant and its contents, which, botanically speaking, make it fruit.” Calgary Herald

In China, watermelon is stir-fried, stewed and often pickled and used as a vegetable.

Well, whatever! It is a fruit as far as I am concerned.

How to Pick a Good Watermelon

  • They are not one of the dirty dozen (the most heavily sprayed produce). They are one of the fifteen most clean non-organic fruits and vegetables.
  • Decide what size of watermelon you want as there are many different sizes.  Watermelons can weigh anywhere from a few pounds to ninety pounds.
  • Do you want a seedless watermelon?  Most seedless watermelons are often not organic so that maybe something for you to consider.
  • Choose a melon that is medium to light green but not yellowing, with several spots of light green on it.
  • Make sure it feels heavy for its size.
  • It is should not be bruised, shriveled, cracked or moldy.  The purpose of the thick rind is to protect the contents inside. Ripe watermelons should also be dark green in color (minor scratches are okay),
  • Check out the bottom of the watermelon; this should have a creamy yellow spot which is where the watermelon sat on the ground while ripening. If this spot is white or green, it may not be ripe as it was picked too soon.
  • The melon should have a faint aroma and the end should be soft.
  • Tap the watermelon with the palm of your hand lightly several times. What you hear should be a somewhat hollow echo. This indicates the fruit is likely fresh and its flesh is very hard, which when they taste best.  If the sound is a thunk as though it solid, that’s no good and too hollow a sound is also not good.  You just have to do the trial and error thing till you learn which watermelons are the best.
  • Good luck finding the sweetest juiciest watermelon.
  • The best watermelons will, of course, be the ones you grow yourself.  Learn how at How to Grow Watermelons.

Tips for Preparing and Storing Watermelon

  • Always wash the exterior of the melon before slicing to remove any bacteria on the surface.
  • After they have been cut store in the fridge. Watermelons retain more nutritional value after cut and stored in the fridge as most other produce.
  • Before eating a piece that has been in the fridge, pull it out long enough for it to go to room temperature. This maximizes its phytonutrient capacity.
  • Store uncut whole watermelons stored at 70 degrees Fahrenheit:  Watermelon stored at 70 F gained up to 40 percent more lycopene and 50% to 139% extra beta-carotene, when compared to freshly picked watermelon, were the findings in a study by USDA’s South Central Agricultural Research Laboratory in Lane, Oklahoma. Watermelons continue to produce nutrients after they are picked; the chilling slows this process. Refrigerated watermelon starts to decay after a week.
  • Watermelons last from 14 to 21 days at 13 degrees Celsius (55 F) after harvest.

Eating Watermelons

  • Eat watermelon on its own. Melons only take 15 – 30 minutes to digest; they do not combine with any other food, always eat alone and wait 30 minutes before eating something else.
  • Eat room temperature watermelon as it is much easier on the stomach.
  • Every part of a watermelon is edible, even the seeds and rinds.
  • My favourite way is to slice it and cut it into cubes and eat it from a big bowl.
  • Watermelon juice is so easy and a wonderful cooling alkalizing beverage and of course as we know filled with nutrients.  Find just how easy it is to make here;  watermelon juice.
  • Yes, you can eat Watermelon Rinds: We usually throw out the hard green rind of the juicy watermelon, but did you know that the watermelon rind has nutritional and remedy benefits? This wasted food can do good things for your body.   Also, using it will cut down on your garbage helping the environment. Read more about the Watermelon Rind.

  • Thank you Diana for all the useful information!!!

    Like you, I love watermelons to and after reading this I got worried a bit because I’m trying to put on weight (my BMI is below 15). You said that it will burn fat in the body and therefore you lose weight. Will that affect me too? I don’t have much fat in my body and the one I do have I don’t want to get rid off. 😀

    Thanks again for this great article!!!!!

    • You are welcome Silvia! As long as you eat a full range of foods and do not need to lose weight eating watermelon will simply help with cleansing which everyone needs to do regardless of weight. In fact cleansing can help to gain weight if that is what the body requires. Our body has an intelligence and will do what is needed.

    p.s. I never met a watermelon I didn’t like. even the very “seedy” ones. pun intended 🙂

    Was curious about history of WM:

    Watermelon is thought to have originated in the Kalahari Desert of Africa. The first recorded watermelon harvest occurred nearly 5,000 years ago in Egypt and is depicted in Egyptian hieroglyphics on walls of their ancient buildings. Watermelons were often placed in the burial tombs of kings to nourish them in the afterlife.

    From there, watermelons spread throughout countries along the Mediterranean Sea by way of merchant ships. By the 10th century, watermelon found its way to China, which is now the world’s number one producer of watermelons.

    The 13th century found watermelon spread through the rest of Europe via the Moors.

    Southern food historian, John Egerton, believes watermelon made its way to the United States with African slaves as he states in his book, “Southern Food.”

    Great. So what’s the definition of a “vegetable?”
    Our vague friend, the dictionary, defines vegetable as “anything made or obtained from plants.” Basically, that means all fruits are also vegetables. So in the grand scheme of things, vegetables and fruits continue to be amongst the healthiest of foods.
