Dragon Fruit Benefits

Dragon Fruit Benefits

Some of the benefits of dragon fruit include:

1. Nutrient-dense

Dragon fruit contains fewer calories and packs vital vitamins and minerals and fibre. The health benefits of fibre are associated with heart health and cholesterol. The soluble fibre present in it aids in removing cholesterol from the intestinal wall by attaching it.

The fruit contains a good amount of Vitamin C. Due to strict diet management, the nutrient needs for body metabolism may fall short. To complete this shortage of nutrients, it is better to take Vitamin C. It ensures proper absorption of all the constituents.

Dragon fruit is an incredible source of antioxidants. The antioxidants work against the free radicals. These free radicals result in oxidative stress in people with diabetes.


Dragon fruit is a low-calorie food. And it is rich in vitamins, minerals and useful plant compounds.

2. Packs Fiber

Dietary fiber is a non-digestible carb that packs several health benefits.

It is advisable to consume 25g of fiber daily for women and 38g for men. Just like antioxidants, fiber supplements fail to exert similar benefits as fiber from foods. Dragon fruit contains 7-8 g of fiber in one cup serving.

Fiber plays a key role in digestion. According to research, it plays a key role in managing heart problems. Fiber works great in maintaining a healthy weight and managing type 2 diabetes.

Also, as per studies, diets rich in fibre guard against colon cancer. Yet, it is vital to note that high-fibre meal plans come with drawbacks. That too, particularly if a person is used to a low-fibre diet. It is good to enhance fiber intake and have enough fluids to avoid stomach uneasiness.


Dragon fruit provides around 7 grams of fibre per serving. And, this makes it an outstanding option for meeting one’s daily fibre requirements.

3. Boosts Immunity

Your body’s ability to fight infection is determined by several different factors, including the quality of your diet. The vitamin C and carotenoids in dragon fruit may boost your immune system and prevent infection by protecting your white blood cells from damage.

The white blood cells in your immune system attack and destroy harmful substances. However, they are extremely sensitive to damage by free radicals. As potent antioxidants, vitamin C and carotenoids can neutralise free radicals and defend your white blood cells against harm.


A high supply of carotenoids and Vitamin C delivers this fruit with strong immune-boosting properties.

4. Fights Chronic Disorders

Free radicals are unstable molecules responsible for cell damage. These might cause ailments and inflammation. One approach to fight this is consuming antioxidant-rich foods such as dragon fruit.

Antioxidants act by counteracting free radicals. As a result, they prevent inflammation and cell damage. As per the study, diets rich in antioxidants might aid in preventing chronic problems. These are cancer, cardiovascular disease, diabetes and arthritis.

Dragon fruit consists of numerous types of effective antioxidants, such as:


Lycopene and beta-carotene are plant compounds offering dragon fruit its rich colour. Meal plans containing carotenoids relate to a decreased risk of cancer and heart problems.

Vitamin C:

There is a strong association between Vitamin C consumption and cancer risk. For instance, higher consumption of Vitamin C has been found to be associated with reduced rates of head and neck cancer.


Many studies also indicate betalains might fight oxidative stress. Also, these compounds have the capacity to suppress tumour cells.

Prominently, antioxidants act best when consumed in natural forms via food instead of supplements or a pill. Actually, antioxidant supplements might exert damaging effects. In addition, consuming these supplements without medical help is not advisable. Instead, it is advisable to have dragon fruit.


Dragon fruit comprises antioxidants such as betalain, Vitamin C, lycopene, and beta-carotene. As per studies, an antioxidant-rich diet has been found to be associated with a decreased risk of chronic problems.

5. Healthy Digestive System

The digestive tract is home to a few 100 trillion different microbes, such as many bacterial species. Researchers think that this microbial community might affect a person’s health. Many studies have found a link between imbalances in the gut and medical problems like heart problems or asthma.

Providing dragon fruit comprises prebiotics. The fruit may likely improve the balance of good bacteria in a person’s gut. Prebiotics are a particular form of fibres. These help to support the growth of healthy bacteria in a person’s gut.

Similar to all fibres, a person’s gut fails to break them down. Yet, the bacteria present in the gut may digest them. They make use of fibre as an energy source for growth. And a person may reap the benefits.

Above all, dragon fruit majorly supports the growth of 2 families of healthy bacteria. These are bifidobacteria and lactic acid bacteria. Frequent intake of prebiotics decreases infection risk in a person’s gut and loose stools. This is due to the reason that prebiotics support the growth of good bacteria.

For instance, a study found that people who had prebiotics prior to and during travel got fewer and less serious incidents of traveller’s diarrhoea. Also, few studies propose that prebiotics might ease signs of colon cancer and IBD.


Dragon fruit may promote the growth of healthy bacteria in the gut, which is associated with a healthy gastrointestinal tract.

6. Good Source of Magnesium

Dragon fruit provides a greater amount of magnesium than many fruits. Dragon fruit contains 18% magnesium of the RDI in one cup. Normally, a person’s body comprises 24 to 28 grams of magnesium.

In spite of this apparently small quantity, magnesium is present in body cells. Magnesium plays a key role in more than 600 vital body processes. For instance, magnesium has a role in reactions required for breaking down of food into:

  • Production of bones
  • Energy
  • Muscle contraction
  • Production of DNA

Much more studies are required, however, a few show that greater ingestion of magnesium might lower the risk of heart problems and stroke. It is also found that diets satisfactory in magnesium content promote the health of bones.


Dragon fruit contains a rich amount of magnesium. It is a mineral required for more than 600 biochemical reactions occurring in a person’s body.

7. Improves Low Iron Levels

Dragon fruit is among iron-containing fresh fruits. Iron helps to transport oxygen throughout a person’s body. Also, iron is vital for breaking down food into energy.

Unluckily, a lot of people fail to receive a satisfactory amount of iron. In actual fact, it has been found that around 30% of the world’s population is short of iron. And this makes the iron deficiency problem a common nutrient shortage universally.

To fight the low levels of iron, it is good to have a diversity of iron-rich foods. Rich iron sources are nuts, seeds, meats, legumes, fish, and cereals. Dragon fruit might be another better alternative. As 1 serving of fruit comprises 8% of the RDI value. Also, dragon fruit comprises vitamin C, which aids a person’s body to absorb iron.


Dragon fruit provides iron in combination with vitamin C. This combo might improve a person’s body’s absorption of this vital mineral.
