Dragon Fruit Facts

I first came to know of dragon fruit way back in the early '80s when a friend brought it back from Vietnam for us to try. This weird-looking fruit failed to tempt us and was left to practically rot in the fridge. Now is a different story, we loved it so much that I had it planted in our small garden. I also learned about the health benefits and the amazing nutritional values of dragon fruit.

Different Types Of Dragon Fruit

Dragon fruit, also known as Pitaya, originates from South America and is now grown in most tropical Asian countries. The skin is covered with 'scales' and comes either as a red-skin or yellow-skin variety.

• The red-skin variety is either white or luminous red flesh.
• The yellow-skin variety is available only in the white flesh.

The popularity is due to the many benefits that dragon fruit has to offer. The red-skin variety with red flesh offers more benefits compared to the other varieties i.e. the red-skin with white flesh and the yellow-skin dragon fruit variety.

For this article, we will explore the benefits of the red-skin variety.

Dragon Fruit Health Benefits

Despite the many years of the fruit's existence, it was only recently that studies were conducted on the health benefits of dragon fruits, which are as follows:

Dragon Fruit for People with Type 2 Diabetes

The statistic shows that people who suffer from diabetes will have increased chances of vascular complications by at least twofold.

Based on the study conducted by the School of Pharmaceutical Sciences of Universiti Sains Malaysia, and published in the US National Library of Medicine National Institutes of Health, dragon fruits, which are rich in antioxidant betacyanins can prevent this combative stress and diabetes.

Red Flesh Dragon Fruit

In another study on patients with Type 2 diabetes who are not dependent on insulin, shows a decrease in blood sugar level by more than 19% when given 600 gm daily dosage of the red flesh red skin dragon fruit over a period of four weeks.

The flavonoid antioxidants present in red flesh dragon fruit are responsible for this reduction. If you suffer from Type 2 diabetes, eating the red flesh dragon fruit can help control your glucose level.

Dragon Fruit May Reduce Cancer Risk

The red pigments in the red flesh dragon fruit are rich in lycopene, flavonoid antioxidants, and phytoalbumins, which help prevent the formation of cancerous cells.

As documented in the American Institute for Cancer Research eNews, the phytochemical lycopene that is present in red flesh dragon fruit can prevent prostate cancer.

In another study by Paweł Pa´sko et al of Jagiellonian University Medical College, Poland, dragon fruits with their high antioxidant properties and cytotoxic potential to colon cancer cells may become an important chemopreventive element of the daily diet.

In addition, flavonoid antioxidants can also prevent inflammatory diseases such as gout and arthritis.

Dragon Fruit May Reduce Cholesterol

Dragon fruit has high levels of insoluble and soluble fibers. 100 gm of fresh dragon fruit gives you 1 gm of fiber. In dried form, the fiber content is even more at 10 gm for every 100 gm of powdered or dried fruit.

These fibers can improve the digestive system, which in turn will reduce the accumulation of dietary cholesterol in your body.

In a clinical study published in the American Journal of Applied Sciences 6 (7): 1341-1346, 2009 edition, eating the red dragon fruit over five weeks saw an impressive drop in the total cholesterol level.

Prebiotic Action of Dragon Fruit

Based on the article in 'Food Chemistry' (June 2010 edition), the fiber in dragon fruit is made up mainly of oligosaccharides. This is not digested in the stomach but acts as prebiotics, which assists in the growth of lactobacilli and bifidobacteria, which are healthy bacteria.

When taken in the right amount, these microorganisms will assist in digestion and keep the immune system strong.

Dragon Fruit Protein, Carbohydrates, and Calories

100 g of dragon fruit gives almost 2.0 g of protein and 9 g of carbohydrates, which is about 3% and 4% of the recommended daily value, respectively.

Pitaya is also very low in calories at only 60 calories, which is about 3% of the daily value

This is good news if you are in a weight management program.

Dragon Fruit Vitamins & Minerals

Dragon fruit has a high dosage of Vitamin C where 100 gm of the fruit gives 500 mg of Vitamin C. It also contains Vitamin A, B1, and E but in smaller amounts.

Mineral contents in dragon fruits include a good dosage of potassium, magnesium, zinc, and phosphorus. In smaller amounts, it has calcium, iron, and copper.

With all these nutritional benefits, dragon fruit can be a complete meal of its own.

Please refer to the table below for a detail breakdown of the vitamins and mineral contents.

Dragon Fruit Nutrition Facts

Dragon Fruit and Pregnancy

Eating fruits during pregnancy is a good habit and red dragon fruit with all the richness in vitamins, minerals, fiber, and fatty acids will be beneficial to a pregnant woman and her unborn baby.

Among its many benefits is its iron content that is essential for a pregnant woman that reduces the chances of anemia. It also contains folates, which are essential for the formation of red blood cells.

Dragon fruit is also rich in fibers and can provide relief from constipation.

Based on the study by A. Widyaningsih et al., it is safe for pregnant women to eat dragon fruit. You can eat it fresh or as part of your mixed fruit salad, as a juice, or as smoothies.

Is Dragon Fruit Stem Edible and Nutritional?

Surprisingly, based on the study by the University Kuala Lumpur, Malaysia, the dragon fruit stem can be processed into powdered form and consumed, as it is rich in nutrient content.

Dragon Fruit Stem Benefits

The study concludes that the premature stem of the red dragon fruit has more nutritional value compared to the matured stem.

Dragon Fruit Taste

Dragon fruit looks unique and exotic but the taste can be bland and uninteresting. Not fiery and intense unlike its name. The red flesh variety is, however, sweeter.

Dragon Fruit Seed contains Omega-3 & Omega-9

The flesh has a nice texture with tiny seeds all over, just like kiwi fruits. Do not be put off by these tiny seeds as there are edible and nutritional. The seeds contain natural oils and fatty acids in the form of linoleic acid and oleic acid (Omega-3 and Omega-9), which are useful for your cardiovascular health.

How to Eat Dragon Fruit

You can cut it in half and spoon it out or cut it into quarters, peel the skin off and serve on a plate. It tastes better if it is chilled. Some people will add a bit of lime juice for added flavor.

Or you can cut it into cubes and serve it as part of your mixed fruit salad.

Dragon Fruit Juice, Sorbet, and Smoothie

For something different, try it as dragon fruit juice, sorbet, or smoothie.

• To make dragon fruit juice, cut the fruit into two, scoop the pulp and blend it. You can add sugar or honey, ginger, and lemon juice if you want. Add water to the consistency you want.
• For dragon fruit sorbet, likewise, blend the dragon fruit pulp with lime juice (and orange juice - optional), until smooth. Then place into an ice cream container, freeze.
• For dragon fruit smoothie, freeze the scooped fruit pulp. When you are ready to make the smoothie, throw in the frozen dragon fruit pulp, add milk (or yogurt) and blend. You can also add other fruits to this dragon fruit smoothie such as banana, pineapple, mango, etc.

Dragon Fruit Skin

You do not eat the dragon fruit skin but in some Southeast Asian countries, the skin is pickled and eaten either on its own or as a salad. Based on a study by the Faculty of Chemical Engineering and Natural Resources, the peel or the skin is actually rich in flavonoids, which are good for anti-inflammatory, anti-tumor, and anti-viral effects.

Dragon Fruit Fun Facts

1. Dragon Fruit flower blooms only at night and will last for one night only. Pollination needs to happen on that one night for it to set fruit.

2. Dragon fruit trees, if maintained properly, can last for over a hundred years.

How to Choose a Ripe Dragon Fruit

Dragon fruit is usually picked mature and ready to eat. If you press it with your thumb and it gives a little, then it is perfect for eating. If it is too soft, then it is over-ripe and the dragon fruit flesh may be too runny. If it is very firm, then you need to rest it for a couple of days for it to ripen.

Do not keep it too long, otherwise, it will be too soft. If you are not ready to eat it yet, put it in the fridge. It can last for up to 2 weeks in the refrigerator.

Dragon fruit that is without blemishes is usually priced higher. I find the quality and taste of the dragon fruit flesh from those with and without blemishes are no different. So, save your money!

But do not buy if it has too many blemishes or blotches as it may be over-ripe. Another sign of over-ripe dragon fruit is the dry and brown tips of its 'leaves.

Where to Buy Dragon Fruit

Dragon fruits are now easily available in most supermarkets. Alternatively, you can try the Asian food market in your area.

The growing season is traditionally from June to late December so you have plenty of time to enjoy this exotic fruit.

Buy Dragon Fruit Online

If you still have difficulty finding dragon fruit in your area, stay cool as it is also available online, but you have to buy them in large quantities!

Yellow Skin Dragon Fruit or Yellow Pitaya

Although this article is on the red dragon fruit variety, it will not be complete without comparative information between the two varieties.

To start with, the yellow dragon fruit plant takes a long time to grow and harvest. Depending on the growing condition, it can produce between four to six fruiting cycles per year, similar to the red skin variety.

The fruit is smaller but is sweeter in taste. The way to eat the fruit is similar to its red skin cousin and because it is sweeter, Yellow Pitaya makes a better juice drink.

Although it is grown mainly for its yellow fruit, the flower has commercial value as well. It has an impressive bloom and is probably the largest cacti flower in the world.

The yellow skin Dragon Fruit is native to the northern part of South America and is not commonly grown in tropical South East Asia, yet.

Based on the research and studies that were mentioned earlier, the red flesh, red-skin dragon fruit with its higher antioxidants content, and the red pigment, which has lypopene, flavanoid, and phytoalbumins, has better therapeutic properties and hence, is the dragon fruit variety to consume.

Although it costs slightly more, it is sweeter and better for our health. Do be careful when you eat this red flesh, red skin dragon fruit as the red pigment will stain your clothes.

If you have not tried it yet go out and buy some. If you have been eating the white flesh variety, this is the time to change to the red flesh variety.

Hi, Julia. This question was asked before and I should have deleted this info but forgot to do so. The source came from a dragon fruit farm website and since it is not an authoritative site, so it could have been a mistake on their part that I failed to check. This B12 is now deleted from the table. My apologies.

Julia on September 11, 2018:

Dragon fruit does not have any Vitamin B12 in it. Where did you get the nutrition information from?

Hello Mazian, I like fruits and enjoy them much daily. However, I had not heard of the dragon fruit. A good mart is available in my city that import fruits from the oriental countries. I will soon check if the fruit is available.

Your pictures are nice. But it is not easy for me to identify it. I will google to get another picture for my understanding. Thank you and enjoy the day.

interesting facts:

1. It is from a cacti tree

2. It is also known as strawberry pear (besides dragon fruit and pitaya)

3. Dragon fruit flower will last only for a day before it whiter. So, it needs to pollinate in the evening before it wilts the next day.

Mazlan A (author) from Malaysia on September 10, 2017:

Ev, there's a quite a few places where you can buy dragon fruit seeds online including for the red variety.

You can google 'dragon fruit seeds online' and you will see a few sites selling them. Or you can go directly to amaozin.com or eBay. You can find a few sellers there too. Good luck.

Ev on September 04, 2017:

I happen to live where Pitaya grow "wild", but only the pink-skinned white variety. I'm sure the red variety would grow here if I could find the seeds. So, I'm looking for sources for seeds of the red variety. Any suggestions?

GregM on April 11, 2017:

I have never seen this fruit before but this summer I will be flying to Vietnam for holiday. Will I be able to buy one there?

Mazlan A (author) from Malaysia on March 25, 2017:

Dorah, not sure if it can grow in South Africa but I am sure you can buy the fruits in your local market. Dragon fruits growers are very aggressive and they are marketing the fruits all over the world.

Dorah on March 19, 2017:

Hi! Interesting info, I live on South Africa. Can the dragon fruit grow here? I have aneamia and vit b12 deficiency, Where can I get the fruit?

Mazlan A (author) from Malaysia on August 31, 2015:

Hi Muhammad Nasir uddin. I have not read any research articles, or any article for that matter that says Dragon Fruit will 'destroy sperm'. In fact one of the causes of low sperm count is lack of Zinc. Dragon fruit on the other hand, is rich in Zinc. Hope this answer your query.

Muhammad nasir uddin on August 22, 2015:

Does it works as antifertility?Will it destroy sperm?

Mazlan A (author) from Malaysia on January 31, 2014:

@chefsref, based on your comment (in my other article on Dates Palm) I don't think Dragon Fruit tree can grow at that temperature range. You need to move South, then it might possible to grow the tree!

Thanks for the visit.

Lee Raynor from Citra Florida on January 22, 2014:

Hey Greatstuff

Yeah, I'm trying to grow Dragonfruit )as well as dates.) I have my doubts due to our freezing weather in the winter but so far they are alive after two frosts.

You have access to a lot of foods that we never see here in North Florida.

You publish some very interesting Hubs!

Danida from London on January 11, 2014:

I've always been fascinated by dragon fruit. The first time I saw a picture of its 'insides' I thought it was fake haha! It just looks so weird...

I've never bought one though as I can never find them.

oldiesmusic from United States on December 26, 2013:

At first I was curious about the dragon fruit, and when I tasted it, it was quite ok. It tasted great, despite staining my clothes (I ate the red variety) and my teeth like my gums were bleeding hehehehe. I couldn't believe that it is related to the cactus (haven't seen the plant yet). Thanks for the wonderful information and for listing the great health benefits of this wonder fruit.
