Dragon fruit—also called pitaya, pitahaya, or strawberry pear—is a member of the Cactaceae family, a cactus species. The bright pink, bulb-shaped fruit is known for its sweet, fresh taste and unique, ornamental appearance. The meat of the dragon fruit may be either pink or white.

Those wondering about dragon fruit nutrition can rest assured that the spiky fruit contains vitamins, fiber, and even iron and healthy fats (unusual for a fruit). Dragon fruit is grown primarily in tropical and subtropical areas of the world, most popular in Asia and Central America. It is less commonly consumed in the U.S.

Let's dive deeper into dragon fruit's benefits.

Dragon Fruit Nutrition Facts

The following dragon fruit nutrition information is provided by the USDA for 6 ounces (170g) of cubed dragon fruit.

Carbs

Dragon fruit is a naturally low-calorie food, with most calories coming from carbohydrates. There are two types of carbohydrates in dragon fruit: naturally occurring sugars (13g per 6-ounce serving) and fiber. You'll get 5 grams of fiber—or about 18% of your recommended daily intake—in a 6-ounce serving.

The exact glycemic index (GI) of dragon fruit has not been recorded, although one study estimates the GI to be similar to that of a banana—48 to 52. As a reference, foods with a GI of 55 or more are considered high-glycemic foods.

Fat

There is a small amount of fat in dragon fruit. The edible seeds contain omega-3 fatty acids, omega-6 fatty acids, and polyunsaturated fat—which are all healthy.

Protein

Dragon fruit provides a small amount of protein, about 2 grams per serving.

Vitamins and Minerals

Dragon fruit provides vitamin C and riboflavin, along with about 17% of your daily recommended intake of magnesium—a mineral responsible for aiding in hundreds of biochemical reactions in the body. Dragon fruit also contains iron, niacin, and calcium.

Dragon Fruit Health Benefits

Like many fruits and vegetables, dragon fruit contains fiber, vitamins, minerals, and antioxidants with beneficial qualities.

Helps Build and Heal Cells

Vitamin C (L-ascorbic acid) is essential for good bone structure, cartilage, muscle, and blood vessels. It promotes wound healing, and may also help to prevent disease.

Vitamin C must be consumed in the diet because our bodies are unable to make it naturally. Vitamin C also aids in iron absorption, and dragon fruit is one of the rare fruits that contain iron (about 1mg per 6-ounce serving, or 7% of the daily value).

Reduces Inflammation

Dragon fruit is rich in flavonoids, one of the many types of antioxidants that can help repair cell damage caused by oxidative stress and reduce inflammation. In turn, this can help the body ward off some chronic diseases.

Improves Digestive Health

Fiber helps boost satiety, improves digestion and regularity, and may help to lower blood cholesterol. Current FDA guidelines recommend 28 grams of fiber per day. Fiber also provides other health benefits, including decreased risk of cancer, obesity, cardiovascular disease, and diabetes.

Helps Manage Blood Sugar

In a collection of four studies, dragon fruit appears to improve blood sugar in people with pre-diabetes. In type 2 diabetes, dragon fruit didn't appear to provide significant outcomes, but there was a trend in improving blood glucose with higher doses of dragon fruit. More studies are warranted to conclude dragon fruits effect on blood glucose.

Allergies

There have been limited reports of allergic reactions to dragon fruit or fruit juice containing dragon fruit. Reported symptoms included itchy, swollen red skin, swelling around the mouth, and severe itching.

If you suspect an allergy to dragon fruit, speak to your healthcare provider to get a proper diagnosis. If you or someone near you experiences a severe reaction after consuming dragon fruit, experts recommend you call 911. Anaphylaxis (a severe allergic reaction) can be life-threatening and it is important to seek immediate medical attention.

Adverse Effects

There has been only limited research on whether dragon fruit interacts with medications. Study authors recommend patients speak with their healthcare provider to get the most personalized information regarding medications and possible interactions.

Varieties of Dragon Fruit

There are three main types of dragon fruit: white flesh with pink skin, red flesh with pink skin, and white flesh with yellow skin. The taste and nutritional benefits of the fruit are the same, regardless of color.

Many people describe the flesh as having a pear-like taste with hints of berry and watermelon. The flesh has a texture that is often compared to kiwi, and the small black seeds are edible, just as in kiwi.

Dragon eye fruit is not the same as dragon fruit. Dragon eye fruit is another name for the longan, which is related to the lychee.

When Dragon Fruit Is Best

The peak season for dragon fruit is summer to early fall. The hardest part about buying dragon fruit may be finding it in your local market. Some, but not all, major grocery stores carry dragon fruit but most Asian markets will sell it. Some farmer's markets may have them as well, depending on the part of the country you live.

Look for fresh fruit with a bright pink color. Avoid dragon fruit with wilted stems or brown markings. The flesh should yield slightly when pressed. If none are ripe, buy a firm fruit and let it ripen a day or two. 

Sometimes dragon fruit juice is more readily available than whole fruit. The juice contains important vitamins and minerals but it doesn't have the fiber the fruit provides. Also, some dragon fruit drinks are mixes of several types of juice and can offer a substantial amount of sugar. Or they are marketed as "dragon fruit flavor," but don't contain dragon fruit.

If you can't find whole dragon fruit in your local market, you can also buy frozen cubed dragon fruit, which is just as healthy. Check the ingredients to ensure you are buying the fruit with no added syrups or sugars.

Storage and Food Safety

Ripe dragon fruit will keep at room temperature for a few days. Or, store in the refrigerator in a plastic bag. Avoid cutting the fruit until you are ready to eat it; once cut, it should be refrigerated in an airtight container. If your dragon fruit starts to turn brown or mushy, discard.

How to Prepare Dragon Fruit

You should only eat the flesh (inside) of the dragon fruit, not the skin. To peel, cut it into quarters and peel the skin back. You can also remove the skin from the whole fruit with a paring knife or cut the fruit in half and scoop out the flesh with a spoon.

You can eat dragon fruit just like you'd eat many other sweet fruits. Throw slices or cubes into a green or fruit salad, or toss in the blender when making a fruit smoothie. Some also use dragon fruit as a garnish for cocktails or other fresh summer drinks.

Dragon fruit pairs well with other tropical fruits like bananas and pineapple. If you're looking for new and interesting breakfast ideas, toss dragon fruit on top of Greek yogurt and sprinkle a tablespoon of granola on top. Or make a batch of whole-wheat pancakes and enjoy them with cubed mango and dragon fruit instead of syrup.
