Dragon fruit là gì?

  • Dragon fruit is a tropical fruit that has become increasingly popular in recent years.
  • Though people primarily enjoy it for its unique look and taste, evidence suggests it may provide health benefits as well.
  • This article takes a look at dragon fruit, including its nutrition, benefits, and how to eat it.
What Is Dragon Fruit?
  • Dragon fruit grows on the Hylocereus cactus, also known as the Honolulu queen, whose flowers only open at night.
  • The plant is native to southern Mexico and Central America. Today, it is grown all over the world.
  • It goes by many names, including pitaya, pitahaya, and strawberry pear.
  • The two most common types have bright red skin with green scales that resemble a dragon — hence the name.
  • The most widely available variety has white pulp with black seeds, though a less common type with red pulp and black seeds exists as well.
  • Another variety — referred to as yellow dragon fruit — has yellow skin and white pulp with black seeds.
  • Dragon fruit may look exotic, but its flavors are similar to other fruits. Its taste has been described as a slightly sweet cross between a kiwi and a pear.

Here are the nutrition facts for a serving of 3.5 ounces, or 100 grams

  • Calories: 60
  • Protein: 1.2 grams
  • Fat: 0 grams
  • Carbs: 13 grams
  • Fiber: 3 grams
  • Vitamin C: 3% of the RDI
  • Iron: 4% of the RDI
  • Magnesium: 10% of the RDI

Given the high amount of fiber and magnesium, as well as the extremely low calorie content, dragon fruit can be considered a highly nutrient-dense fruit.

SUMMARYDragon fruit is a low-calorie fruit that is high in fiber and provides a good amount of several vitamins and minerals.

  • Provides Several Antioxidants
  • Dragon fruit contains several types of
  • These are compounds that protect your cells from unstable molecules called free radicals, which are linked to chronic diseases and aging
  • These are some of the main antioxidants contained in dragon fruit pulp
  • Betalains: Found in the pulp of red dragon fruit, these deep red pigments have been shown to protect “bad” LDL cholesterol from becoming oxidized or damaged
  • Hydroxycinnamates: This group of compounds has demonstrated anticancer activity in test-tube and animal studies
  • Flavonoids: This large, diverse group of antioxidants is linked to better brain health and a reduced risk of heart disease

One study compared the antioxidant properties of 17 tropical fruits and berries.

While dragon fruit’s antioxidant capacity was not especially high, it was found to be best at protecting certain fatty acids from free radical damage .

SUMMARYDragon fruit contains several antioxidants that protect your cells from damage. These include betalains, hydroxycinnamates, and flavonoids.

Potential Health Benefits
  • Animal studies suggest that dragon fruit may provide various health benefits.
  • Many of these are likely due to its fiber and antioxidant content.
  • Both red and white varieties of dragon fruit have been shown to reduce insulin resistance and fatty liver in obese mice
  • In one study, mice on a high-fat diet who received an extract of the fruit gained less weight and had reductions in liver fat, insulin resistance, and inflammation, which were attributed in part to beneficial changes in gut bacteria
  • Dragon fruit contains prebiotic fiber that promotes the growth of beneficial bacteria in your gut — potentially improving metabolic health
  • Although this fruit may improve certain features of metabolic syndrome — a condition associated with type 2 diabetes — not all effects may be favorable.
  • In a study in mice on a high-fat, high-carb diet, the group that received dragon fruit juice had better blood sugar responses and reductions in some liver enzyme markers, while another liver enzyme marker significantly increased
  • In another study, rats with diabetes treated with an extract from the fruit had a 35% reduction in malondialdehyde, a marker of free-radical damage. They also had less arterial stiffness, compared to the control group
  • Study results on the effects of dragon fruit on type 2 diabetes in people are inconsistent, and more research is needed to confirm these beneficial effects

  • Animal studies suggest that dragon fruit may improve insulin resistance, liver fat, and heart health. However, the results of human studies are inconsistent.
  • Overall, dragon fruit appears to be safe. However, people may develop an allergic reaction in some rare cases.
  • In two cases, women with no history of food allergies developed anaphylactic reactions after consuming a fruit mixture that contained dragon fruit. Testing confirmed that they had antibodies against dragon fruit in their blood .
  • These are the only two reported allergic reactions at this point, but other people may be allergic to this fruit without knowing it.
