Dragon Fruit: The Unique and Nutritious White and Red Flesh Exotic Fruit

An Introduction to Dragon Fruit, the Unique and Nutritious White Flesh Fruit

Dragon fruit, also known as pitaya or the strawberry pear, is a brightly colored, sweet yet mildly flavored fruit grown in tropical and subtropical regions around the world. The oblong shaped fruit has a vibrant pink or yellow skin with overlapping scales resembling that of a dragon, hence its name. But it's the inside of the dragon fruit that captivates people - the flesh is white with tiny black seeds spread throughout it. When sliced open, the white flesh speckled with black provides a visually striking appearance that has made dragon fruit increasingly popular not just for its taste, but for its photogenic qualities.

The History and Origins of Dragon Fruit

Dragon fruit is believed to be native to southern Mexico and Central America. It has also been grown and used for centuries in Southeast Asian countries like Vietnam, Thailand and Malaysia. The plants were brought to Asia in the 19th century by French colonists. Today, dragon fruit is commercially grown in many tropical regions including Israel, Australia, Hawaii and other parts of the United States.

Its genus name Hylocereus means "looking like wax" which refers to the vining epiphytic plants that dragon fruit comes from. There are three main types of dragon fruit - Hylocereus undatus (red flesh), Hylocereus costaricensis (red flesh), and Hylocereus megalanthus (white flesh). The most commonly consumed variety worldwide is Hylocereus undatus which has red skin and red flesh dotted with tiny black seeds. But it is the less commonly found Hylocereus megalanthus variety with white flesh that is gaining popularity in recent years.

Appearance and Flavor of White and Red Dragon Fruit

Both the red and white flesh dragon fruits have leathery, bright pink or yellow outer skin speckled with scaly spines called "areoles". The texture and flavor though differ slightly between the two varieties.

The white flesh variety has a light sweet taste reminiscent of kiwi or pear, but milder in flavor. The flesh has a crunchy, edible texture dotted with tiny black seeds similar to kiwi fruit seeds. When ripe, the white flesh of Hylocereus megalanthus is crisp and juicy.

Meanwhile, the commonly found red flesh variety Hylocereus undatus and Hylocereus costaricensis have a more intense fruity flavor often described as a mix between kiwi and watermelon. The red flesh has a softer, jam-like texture that melts in the mouth when ripe. It also has edible tiny black seeds spread throughout its red flesh.

Nutrition Facts and Health Benefits of Dragon Fruit

Both red and white dragon fruit varieties are nutritious fruits packed with beneficial vitamins, minerals and antioxidants. Here are some of the ways dragon fruit can boost your health:

High in Antioxidants

Dragon fruit contains several types of antioxidants including flavonoids, phenolic acids, betacyanins and betaxanthins. These compounds combat oxidative stress from free radicals and can help reduce inflammation in the body.

Good Source of Vitamin C

One cup of dragon fruit provides 10% of the RDI for vitamin C, an essential nutrient that acts as an antioxidant and is important for immune health and collagen production.

Contains Iron

Dragon fruit is a decent plant-based source of iron, providing 8% of the RDI per cup. Iron is a key component of red blood cells that helps transport oxygen throughout the body.

High in Fiber

There are 2 grams of dietary fiber in one cup of dragon fruit, which promotes good digestion and gut health. The fiber may also help lower blood sugar spikes.

Provides Other Micronutrients

Dragon fruit contains small amounts of B-vitamins like thiamine and riboflavin as well as some magnesium, phosphorus and zinc.

Potential Health Benefits of Eating Dragon Fruit

Research into dragon fruit is still in the early stages, but some studies have linked consuming it to possible health benefits:

May Aid Weight Loss

The combination of fiber, antioxidants and low calories/sugar in dragon fruit could potentially help with dropping unwanted pounds. One study found that a pre-meal dragon fruit smoothie helped obese adults feel fuller.

May Reduce Heart Disease Risk

The antioxidant lycopene found in pink and red dragon fruits may help lower LDL (bad) cholesterol and reduce arterial plaque buildup, thus lowering heart disease risk.

Could Help Manage Diabetes

Studies show compounds in dragon fruit may help regulate blood sugar spikes in diabetics and prediabetics. The fiber can also slow the release of sugar into the bloodstream.

May Have Anti-Cancer Activity

Antioxidants like lycopene and betacyanins in dragon fruit showed anti-cancer abilities in some test tube studies, but more research is needed to confirm these effects.

Could Boost Gut Health

Prebiotics in dragon fruit may help feed healthy probiotic gut bacteria, improving gut health and digestion. More human studies are needed in this area however.

How to Choose and Store Dragon Fruit

Pick dragon fruits that feel heavy for their size with bright, evenly colored skin free of blemishes or bruises. Unripe dragon fruit has a greenish tinge with spiky scales. Ripe fruits have vivid pink, red or yellow skin with more flared scales.
