Blue Watermelon: Health Benefits, Nutrition, Calories and How to Eat It

What Is Blue Watermelon and Is It Healthy?

Blue watermelon is an unusual name that can refer to watermelon varieties or novelty fruits described as having blue colouring. However, naturally blue-fleshed watermelon is not a widely recognised commercial variety. Traditional watermelons usually have green skin and red, pink, yellow or orange flesh, depending on the variety. Watermelon is a refreshing fruit known for its high water content, naturally sweet flavour and versatility in healthy recipes. I love to introduce flavours into my diet, and love to eat in volume food, and find new ways to introduce new ingredients to my diet!

What Does Watermelon Contain in Vitamins and Minerals?

Watermelon contains a variety of vitamins, minerals, water and naturally occurring plant compounds that contribute to its nutritional value.

Vitamin C

Vitamin A, provided as beta-carotene in red and pink varieties

Potassium

Magnesium, in smaller amounts

Fibre

Lycopene, particularly in red-fleshed varieties

Natural plant compounds

Its refreshing flavour and versatility make it easy to enjoy in many different ways.

You can eat watermelon:

Fresh as a snack

Added to fruit salads

Blended into smoothies

Mixed into yoghurt bowls

Frozen into refreshing fruit treats

Added to salads with ingredients such as mint and feta

Used in desserts and healthy recipes

If you have come across a product described as blue watermelon, check the variety and its source, as the name does not necessarily mean the flesh is naturally blue.

Is Watermelon Healthy?

Yes, watermelon is a nutritious fruit that can be part of a healthy and balanced diet.

It contains a high proportion of water, alongside natural sugars, vitamin C and other plant compounds. Red-fleshed watermelon also provides lycopene, a naturally occurring pigment that gives the fruit its characteristic colour.

Although fruit contains natural sugars, it also comes with beneficial nutrients that help make it a valuable part of a balanced diet. Mix fruit in with different things, and make a fruit salad!

Healthy eating is not just about avoiding certain foods. It is about choosing a variety of whole foods that provide your body with the nutrients it needs! I love volume eating, and a variety, give me a buffet and it’s my dream! So I like to tell people that it’s not about restricting, it’s actually about finding out how to increase in volume with certain foods in fruit and veg.

Watermelon is a great example of a fruit that offers hydration, flavour and nutrition in one simple food.

Watermelon Contains Natural Plant Compounds

One of the interesting nutritional features of watermelon is its naturally occurring plant compounds.

Red-fleshed watermelon contains lycopene, a carotenoid responsible for much of its red colour. Lycopene has antioxidant properties and has been studied for its role in human health.

Watermelon also contains other plant compounds, although the amounts vary depending on the variety and the fruit’s ripeness.

Antioxidants help protect cells from oxidative stress caused by free radicals.

A diet rich in a variety of plant foods provides a wider range of beneficial compounds.

Other foods containing antioxidant compounds include:

Berries

Citrus fruits

Leafy greens

Tomatoes

Red peppers

Watermelon is another refreshing fruit option that can help add variety to your diet!

Can Watermelon Support Digestion?

Watermelon contains water and a small amount of dietary fibre, both of which contribute to its place in a balanced diet.

Fibre supports:

Normal digestion

Healthy bowel movements

Feeling satisfied after meals

A healthy gut environment

Many people do not get enough fibre in their daily diet, so adding more fibre-rich fruits and vegetables can be beneficial.

Watermelon is not particularly high in fibre compared with fruits such as raspberries, pears or apples, but it can still contribute to your overall fruit intake.

I love finding ways to include different fruits in my meals, whether that means adding them to a fruit salad, combining them with yoghurt or simply enjoying them as a snack.

Watermelon Provides Hydration

One of the main benefits of watermelon is its high water content.

Watermelon is made up of approximately 92% water, making it a refreshing option, particularly during warmer weather.

Water is essential for normal bodily functions, including temperature regulation, digestion and the transportation of nutrients.

Although eating water-rich fruits can contribute to your overall fluid intake, it is still important to drink enough fluids throughout the day.

Other water-rich fruits include:

Strawberries

Oranges

Melon

Grapefruit

Watermelon is an easy and enjoyable way to include more water-containing foods in your diet.

Is Watermelon Good for Skin?

Watermelon contains vitamin C and, in red-fleshed varieties, lycopene. These nutrients and plant compounds contribute to its nutritional value.

Vitamin C supports normal collagen formation, which helps maintain normal skin structure. Lycopene has antioxidant properties, although eating watermelon alone cannot guarantee improvements in skin health.

Healthy skin is influenced by many lifestyle factors, including:

Nutrition

Hydration

Sleep

Exercise

Skincare habits

Sun protection

Adding nutrient-rich fruits like watermelon can be one part of a lifestyle that supports healthy-looking skin.

Rather than relying on one particular food, focus on eating a variety of fruits and vegetables that provide different nutrients.

Watermelon Provides Potassium

Watermelon contains potassium, an important mineral that supports normal bodily functions.

Potassium contributes to:

Normal muscle function

Normal nervous system function

Maintaining normal blood pressure

Including a variety of potassium-containing foods helps support a balanced and nutritious diet.

Other sources of potassium include:

Bananas

Avocado

Sweet potatoes

Beans

Leafy greens

Watermelon contributes to your overall potassium intake, although it is not as concentrated a source as some other foods.

Can Watermelon Help With Weight Management?

Watermelon can fit into a balanced weight management plan because it is naturally low in calories and contains a high proportion of water.

Fresh watermelon contains approximately 30 calories per 100 grams, making it a refreshing option if you enjoy eating larger portions of fruit.

Foods containing water can add volume to meals and snacks, although how satisfying a meal feels also depends on its fibre, protein, fat content and overall composition.

However, healthy weight management is not about focusing on one specific food.

It is about creating balanced habits that include:

Plenty of fruits and vegetables

Protein sources

Whole foods

Regular movement

Sustainable choices

Watermelon can be a refreshing addition to a balanced lifestyle, particularly if you enjoy volume eating and experimenting with different fruit combinations.

Why Is Watermelon Popular in Healthy Recipes?

One reason watermelon is so popular is that it is naturally sweet, refreshing and easy to prepare.

It can add flavour, colour and hydration to meals without needing many extra ingredients.

Popular ways to enjoy watermelon include:

Smoothies

Fruit bowls

Fresh snacks

Frozen fruit treats

Fruit salads

Summer salads

Homemade sorbets

Fruit skewers

Salads, yes, you can start adding fruit to your veg salads! Figure out which ones you like and start to add them in!

Its refreshing flavour means it pairs well with many ingredients.

Watermelon works especially well with:

Lime

Mint

Strawberries

Feta

Cucumber

Berries

Lemon

You can also freeze watermelon chunks and blend them into a refreshing summer snack. It is a simple way to experiment with different textures and flavours.

Is Watermelon Better Than Other Fruits?

Watermelon is a nutritious fruit, but it is not about one fruit being better than another.

Different fruits provide different nutrients.

For example:

Berries provide fibre and various antioxidant compounds

Oranges provide vitamin C

Bananas provide potassium

Avocado provides unsaturated fats

Watermelon provides water, vitamin C and naturally occurring plant compounds

Red-fleshed watermelon also contains lycopene, while the nutritional composition of other watermelon varieties can differ.

The healthiest diet includes a variety of different fruits and vegetables rather than relying on one particular food.

How To Add More Watermelon To Your Diet

Adding watermelon to your meals is simple, and there are plenty of ways to enjoy it throughout the day.

Try:

Chopping it into a fruit salad

Adding it to smoothies

Freezing chunks for a refreshing snack

Mixing it with yoghurt

Combining it with berries

Adding it to a cucumber and mint salad

Making homemade watermelon sorbet

Because of its juicy texture and naturally sweet flavour, watermelon is an easy fruit to experiment with.

If you have found a fruit advertised as blue watermelon, check the botanical variety and seller information before buying it, as naturally blue watermelon flesh is not a commonly established variety.

Are There Any Downsides To Eating Watermelon? How Many Calories Are In Watermelon?

Watermelon is generally a nutritious fruit, but, like any food, balance is important!

Fresh watermelon contains approximately 30 calories per 100 grams, although the exact nutritional values can vary slightly depending on the variety and ripeness.

It also contains natural sugars, water and small amounts of fibre.

Some people may experience bloating or digestive discomfort after eating large amounts of watermelon. Watermelon also contains fermentable carbohydrates, including fructose, which may trigger symptoms in some people with irritable bowel syndrome.

If you are tracking your calorie intake, remember that adding ingredients such as sugar, syrups or sweetened toppings will change the overall calorie content of your meal.

It is also worth remembering that watermelon provides valuable nutrients alongside its natural sugars.

A balanced diet can include a wide range of foods, and there is no need to avoid naturally sweet fruit simply because it contains sugar.

Final Thoughts: Should You Try Watermelon?

Watermelon is a delicious, refreshing fruit that provides hydration, vitamin C and naturally occurring plant compounds. Red-fleshed varieties also provide lycopene, which contributes to their characteristic colour.

While naturally blue-fleshed watermelon is not a widely recognised commercial variety, conventional watermelon is an easy and versatile fruit to enjoy as part of a balanced diet.

Whether you enjoy it fresh, frozen into snacks, blended into smoothies or added to salads, watermelon is a simple way to bring more colour, flavour and variety into everyday eating.

Healthy eating does not have to be complicated. Sometimes discovering new ways to enjoy familiar whole foods is one of the easiest ways to make meals more exciting and nourishing.

I love volume eating, experimenting with different flavours and finding new ways to introduce ingredients into my diet. Watermelon is a great fruit to experiment with because it is refreshing, versatile and easy to combine with so many different foods!
