Health Benefits of Dragon Fruit
Dragon fruit is thought to assist the body in:
Helping stabilize blood sugar. Dragon fruit has been shown to improve glucose metabolism, keeping blood sugar levels steady in people with hyperglycemia and diabetes.
Decreasing cholesterol levels. Dragon fruit provides a healthy amount of monounsaturated fats, which helps reduce harmful cholesterol (LDL) and promotes cardiovascular health.
Strengthening immunity. This fruit is rich in vitamin C, which strengthens the immune system by enhancing white blood cell activity in order to fight infections.
Moreover, since the fruit is composed of 80% water, it is low in calories, which helps with weight control.
How It Works
Aside from normalizing bowel movements to promote gastrointestinal health, foods high in fiber can help regulate diabetes by keeping blood sugar levels even. Since fiber is indigestible, it prevents the body from producing too much insulin. Excess insulin blocks the use of stored glucose and prevents the body from making glucose from non-carbohydrate foods. This can lead to daily fluctuation in glucose levels.
Dragon fruit also provides consumers a healthy amount of monounsaturated fats, which help decrease bad cholesterol (LDL) levels and increase good cholesterol (HDL) levels. LDL cholesterol forms plaque within arteries, making them less flexible. Heart attacks or strokes happen when a clot forms in a blocked artery. HDL cholesterol assists in removing LDL cholesterol from the arteries by carrying it to the liver. In the liver, LDL cholesterol is broken down and excreted from the body, thus promoting cardiovascular health.
Dragon Fruit Side Effects
When consumed in moderation, dragon fruit has no known serious side effects. However, eating excessive amounts may lead to diarrhea because of the fruit's laxative properties.
Overconsumption may also lead to a harmless, reddish hue in the urine or feces, which is referred to as pseudohematuria.
Dragon Fruit Cautions
It is most likely safe for everyone to consume dragon fruit in normal portion sizes; however, it is not recommended to consume dragon fruit in an attempt to cure any ongoing ailments or diseases. Although there is no research disapproving consumption of dragon fruit for a specific group of people, it is recommended to eat a balanced diet that includes five daily servings of fruits and vegetables.
Always consult with a trusted medical professional before making drastic diet changes or beginning a supplement plan.
Dragon Fruit Nutrition
Dragon fruit's nutritional value includes good amounts of vitamin C (ascorbic acid), a water-soluble nutrient, crucial for proper iron absorption and essential for normal body function. Because it is not stored in the body, it must be obtained daily from one's diet. Vitamin C helps strengthen the immune system by stimulating the defensive action of white blood cells against invading pathogens.
While 2,000 - 3,000 daily milligrams of vitamin C can effectively protect the immune system, the intake of just 500 milligrams of vitamin C also increases the body's production and blood levels of glutathione, an antioxidant that detoxifies bacterial waste products and has some beneficial influence on the immune system.
Additionally, dragon fruit provides small quantities of minerals, mainly iron, phosphorus and calcium, as wells as vitamins B2 (rivoflavin) and B3 (niacin).
100 grams of dragon fruit provide 60 calories and 4% of the daily value for dietary fiber.

Dragon fruit originate from cactus plants that belong to the genus Hylocereus and the botanical group Cactaceae, also known as the cactus family, which comprises over 122 genera and about 1,700 species, most of them with succulent, spiny stems. It can go by a few names other than dragon fruit, including pitaya, pitahaya, or 'strawberry pear.'The name of the genus derives from the Greek words hyle, meaning 'woodland', and cereus, the name of a large genus of the cactus family. The combination of both refers to the occupation of wooded lands by cacti.
Related Species and Varieties of Dragon FruitThere are about 16 species of Hylocereus, all native to Central and northern South America. However, the two main varieties of dragon fruit grown for production are H. undatus, which has bright pink skin and white flesh, and H. costaricensis, which also has bright pink skin, but varying hues of pink flesh. Another variety of dragon fruit, also commercially cultivated, is H. megalanthus, with yellow skin and white flesh.
The dragon fruit is native to Central America, where it is generally known as a pitahaya in Mexico and pitaya roja in the rest of Central and northern South America.
According to Aztec literature, pitahaya fruits where consumed as far back as the 13th century. It is believed that the French brought the fruit to Vietnam, where it is now grown extensively, from Nicaragua and Colombia. Others claim it came from South American Guyana around 1870.
Dragon fruit is thought to be native to Mexico as well as Central and South America. However, there are many other countries outside of North and South America that commercially produce the fruit, including Vietnam, Thailand, Malaysia, and Israel. The United States imports the majority of its white-fleshed fruit from Southeast Asia, mainly Vietnam.
Acreage of dragon fruit within the United States is growing but still limited. California is the primary producer, followed by Florida and Hawaii. The demand for this newly-emerging crop is currently higher than the supply, creating a possible opportunity for more commercial farms to open up nationwide.
Dragon fruit can be used for anti-aging facial masks due to its high amount of antioxidants. A paste is made out of the fruit with yogurt. After letting the paste settle on the face for 20 minutes, it can be washed off with lukewarm water. Making a straight paste from the fruit flesh helps treat acne.
