Dragon Fruit

Unleash your inner dragon with dragon fruit

Dragon fruit also called pitaya, is a fruit of the genus Stenocereus, which include several species of cactus, native to the Americas. The fruits have characteristic black seeds and can either be red color with white pulp, red color with red pulp or yellow color with white pulp (1).

Dragon fruits is rich in fiber, minerals and vitamins that make it very beneficial for the health. It also contains many polyphenolic compounds that have antioxidant and anti-inflammatory properties that our bodies need (2). Here are a few of the health benefits of dragon fruit.

  1. Helps with digestion. Dragon fruit is loaded with fiber which increases movements in the gastrointestinal tract. They absorb water in the intestines and add bulk to stools thus preventing constipation. By lubricating the gut and easing the passage of food and waste, they also prevent hemorrhoids (swelling of veins in the lower rectum and anus) which can cause piles, bleeding, itching and pain (3).

  2. Reduces cholesterol levels. Soluble fiber present in dragon fruit reduces cholesterol by binding to them in the small intestines, thus decreasing their absorption into the bloodstream. Excess cholesterol can cause fat build up in the walls of the arteries, narrowing blood flow to the heart muscles. This is the onset of atherosclerosis which is a risk factor for coronary heart disease (4). Also, betalains contained in red dragon fruits, inhibit the oxidation of low lipoprotein cholesterol (LDL), preventing oxidative stress. Oxidative stress is also a risk factor for the development of cardiovascular disease (5).

  3. Enhances brain health. Flavonoids in dragon fruits have neuroprotective effects in the brain such as protecting neurons from injuries and stifling inflammation. They also enhance learning, memory, and cognitive abilities. They also trigger the induction of angiogenesis (the development of new blood vessels) in the hippocampus by stimulating cerebral vascular and peripheral blood flow. The hippocampus plays a major role in memory and learning, and damage or injury in the hippocampus results in memory loss as seen in patients with diseases like Alzheimer’s disease (6).

  4. Helps fight cancer. Dragon fruit contains hydroxycinnamates which are potent antioxidants that chelate free radicals that cause oxidative stress and destroy cells. Oxidative stress is implicated in the pathogenesis of cancer as it enhances mutations in the DNA, or increase damage to DNA, variability in the genome and proliferation of cells. Vitamin C present in dragon fruit is also a potent antioxidant which helps prevents oxidative stress in the body (7). Hydroxycinnamates also have been reported demonstrate anti-carcinogenic activities in several cancer cell lines. They initiate cell cycle arrest, inhibit cell proliferation, impede angiogenesis, prevent apoptosis, and stimulate proteins that suppress tumors amongst others (8).

  5. Boosts immunity. Dragon fruit contains prebiotics that nourish microbiota in our digestive tracts. The oligosaccharides it contains for example, stimulate the growth of healthy bacteria like Lactobacillus and Bifidobacterium. These bacteria assist in digesting food, absorption of nutrients and fighting off pathogenic bacteria that cause diseases and weaken our immune system (9, 10).

Dragon fruits is therefore an exceptional tropical fruit that should be included in your diet. It can be eaten by cutting the fruit open, scooping out the pulp and eating directly, or in smoothies or dicing and eating in salads.
