11 Surprising Benefits and Uses of Black Rice
Black rice gets its signature black-purple color from a pigment called anthocyanin, which has potent antioxidant properties.
In ancient China, it's said that black rice was considered so unique and nutritious that it was forbidden for all but royalty.
Today, thanks to its mild, nutty flavor, chewy texture, and many nutritional benefits, black rice can be found in numerous cuisines around the world.
Here are 11 benefits and uses of black rice.
1. Good Source of Several Nutrients
Compared with other types of rice, black rice is one of the highest in protein.
- Calories: 160
- Fat: 1.5 grams
- Protein: 4 grams
- Carbs: 34 grams
- Fiber: 1 gram
- Iron: 6% of the Daily Value (DV)
Black rice is a good source of several nutrients, particularly protein, fiber, and iron.
2. Rich in Antioxidants
In addition to being a good source of protein, fiber, and iron, black rice is especially high in several antioxidants.
Antioxidants are compounds that protect your cells against oxidative stress caused by molecules known as free radicals.
They're important, as oxidative stress has been associated with an increased risk of several chronic conditions, including heart disease, Alzheimer's, and certain forms of cancer.
Despite being less popular than other rice varieties, research shows that black rice has the highest overall antioxidant capacity and activity.
In fact, in addition to anthocyanin, black rice has been found to contain over 23 plant compounds with antioxidant properties, including several types of flavonoids and carotenoids.
Therefore, adding black rice to your diet can be an easy way to incorporate more disease-protecting antioxidants into your diet.
Research shows that black rice contains over 23 types of antioxidants and has the highest antioxidant activity of all rice varieties.
3. Contains the Plant Compound Anthocyanin
Anthocyanins are a group of flavonoid plant pigments that are responsible for the purple color of black rice, as well as several other plant based foods like blueberries and purple sweet potatoes.
Research shows that anthocyanins have strong anti-inflammatory, antioxidant, and anticancer effects.
Furthermore, animal, test-tube, and population studies have shown that eating foods high in anthocyanins may help protect against several chronic diseases, including heart disease, obesity, and some forms of cancer.
Anthocyanin is a pigment that's responsible for the black-purple color of forbidden rice. It's also been found to have potent anti-inflammatory, antioxidant, and anticancer effects.
4. May Boost Heart Health
Research on black rice's effects on heart health is limited. However, many of its antioxidants have been shown to help protect against heart disease.
Flavonoids like those found in black rice have been associated with a decreased risk of developing and dying from heart disease.
Additionally, early research in animals and humans suggests that anthocyanins may help improve cholesterol and triglyceride levels.
One study in 120 adults with high cholesterol levels found that taking two 80-mg anthocyanin capsules per day for 12 weeks resulted in significantly improved HDL (good) cholesterol levels and significantly reduced LDL (bad) cholesterol levels.
Another study analyzing the effects of a high cholesterol diet on plaque accumulation in rabbits found that adding black rice to the high cholesterol diet resulted in 50% less plaque buildup, compared with diets containing white rice.
While this study suggests that eating black rice may protect against heart disease, these results have not been observed in humans.
Black rice contains antioxidants that have been shown to help protect against heart disease. However, more research is needed to understand black rice's effects on heart disease.
5. May Have Anticancer Properties
Anthocyanins from black rice may also have potent anticancer properties.
A review of population based studies found that higher intake of anthocyanin-rich foods was associated with a lower risk of colorectal cancer.
Furthermore, a test-tube study found that anthocyanins from black rice reduced the number of human breast cancer cells, as well as slowed their growth and ability to spread.
While promising, more research in humans is needed to fully understand the ability of the anthocyanins in black rice to reduce the risk and spread of certain types of cancer.
Early research suggests that the anthocyanins in black rice may have strong anticancer properties, but more studies are needed.
6. May Support Eye Health
Research shows that black rice contains high amounts of lutein and zeaxanthin — two types of carotenoids that are associated with eye health.
These compounds work as antioxidants to help protect your eyes from potentially damaging free radicals.
In particular, lutein and zeaxanthin have been shown to help protect the retina by filtering out harmful blue light waves.
Research suggests that these antioxidants may play an important role in protecting against age-related macular degeneration (AMD), which is the leading cause of blindness worldwide. They may also decrease your risk of cataracts and diabetic retinopathy.
Finally, a 1-week study in mice found that consuming anthocyanin extract from black rice resulted in significantly less retinal damage when animals were exposed to fluorescent lights. Still, these findings have not been replicated in humans.
Black rice contains the antioxidants lutein and zeaxanthin, both of which have been shown to protect your retina from potentially damaging free radicals. While anthocyanins may also protect eye health, research in humans is currently lacking.
7. Naturally Gluten-Free
Gluten is a type of protein found in cereal grains, such as wheat, barley, and rye.
People with celiac disease need to avoid gluten, as it triggers an immune response in the body that damages the small intestine.
Gluten can also cause negative gastrointestinal side effects, such as bloating and abdominal pain, in individuals with gluten sensitivity.
While many whole grains contain gluten, black rice is a nutritious, naturally gluten-free option that can be enjoyed by those on a gluten-free diet.
Black rice is naturally gluten-free and can be a good option for those with celiac disease or gluten sensitivity.
8. May Aid Weight Loss
Black rice is a good source of protein and fiber, both of which can help promote weight loss by reducing appetite and increasing feelings of fullness.
Furthermore, early animal research suggests that anthocyanins like those found in black rice may help reduce body weight and body fat percentage.
One 12-week study found that giving mice with obesity on a high fat diet anthocyanins from black rice resulted in a 9.6% reduction in body weight. However, these results have not been replicated in humans.
While research on black rice's role in weight loss in humans is limited, it has been found to help reduce weight when combined with brown rice.
In a 6-week study in 40 women with excess weight, those who ate a mix of brown and black rice up to 3 times per day on a calorie-restricted diet lost significantly more body weight and body fat than those eating white rice.
Given that black rice is a good source of protein and fiber, it may aid weight loss. Also, while animal studies have suggested that anthocyanins may have benefits for weight loss, more research in humans is needed.
9–10. Other Potential Benefits
Black rice may also offer other potential benefits, including:
- Lower blood sugar levels. Animal studies suggest that eating black rice and other anthocyanin-containing foods may help reduce blood sugar levels in those with type 2 diabetes. Human studies are needed to confirm these effects .
- May decrease your risk of non-alcoholic fatty liver disease (NAFLD). A study in mice found that adding black rice to a high fat diet significantly reduced fat accumulation in the liver.
While more research is needed, black rice may help lower blood sugar levels in individuals with type 2 diabetes and reduce the risk of NAFLD.
11. Easy to Cook and Prepare
Cooking black rice is easy and similar to cooking other forms of rice.
To prepare it, simply combine rice and water or stock in a saucepan over medium-high heat. Once boiling, cover it and reduce the heat to a simmer. Cook the rice for 30–35 minutes, or until it's tender, chewy, and all the liquid has been absorbed.
Remove the pan from the heat and let the rice sit for 5 minutes before removing the lid. Use a fork to help fluff the rice before serving.
Unless specified otherwise on the package, for every 1 cup (180 grams) of uncooked black rice, use 2 1/4 cups (295 ml) of water or stock.
To keep the rice from becoming gummy when cooking, it's recommended to rinse the rice under cool water before cooking to remove some of the extra starch on the surface.
Once the rice is ready, you can use it in any dish in which you would use brown rice, such as in a grain bowl, stir-fry, salad, or rice pudding.
Black rice is prepared similarly to other types of rice and can be added to a variety of savory and sweet dishes.
The Bottom Line
While not as common as other types of rice, black rice is the highest in antioxidant activity and contains more protein than brown rice.
As such, eating it may offer several health benefits, including boosting eye and heart health, protecting against certain forms of cancer, and aiding weight loss.
Black rice is more than just a nutritious grain. When cooked, its deep purple color can turn even the most basic meal into a visually stunning dish.
If you want to try black rice and can't find it locally, shop for it online.

Overthinkers are people who are buried in their own obsessive thoughts. Imagine being in a large maze where each turn leads into an even deeper and knottier tangle of catastrophic, distressing events — that is what it feels like to them when they think about the issues that confront them.
Ruminating<p>According to the late Susan Nolen-Hoeksema, a professor of psychology at Yale University, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5796420/" target="_blank">ruminating</a> involves replaying a problem over and over in your mind. We ruminate by obsessing over our thoughts and thinking repetitively about various aspects of a past situation.</p><p>It usually involves regret, self-loathing and self-blaming. Rumination is associated with the development of depression, anxiety and eating disorders. </p><p>People prone to such patterns of thought may, for example, overanalyze every single detail of a relationship that breaks up. They often blame themselves for what has happened and are overcome with regret, with typical thoughts being: </p><p>- I should have been more patient and more supportive. </p><p>- I have lost the most perfect partner ever. </p><p>- No one will love me again.</p>
Worrying<p>Worrying is wanting to predict the future. It involves negative thoughts about things that might and might not happen.</p><p>- They'll not like me in the interview; they'll not give me the job. </p><p>- I haven't heard back from other employers. How long will I be unemployed?</p><p>These thoughts are energy-draining and distressing. They could happen to anyone under stress. But when you reach the point where your thoughts and worrying are preventing you from doing what you want to do — from living your life to the fullest — then you should take action.</p>
Catch Yourself Overthinking<p>Reuben Berger, a psychotherapist at the university hospital in the western German city of Bonn, recommends several practical steps that you could employ in your daily routine when you catch yourself worrying or ruminating.</p><p>One effective remedy, says Berger, is the <a href="https://www.uofmhealth.org/health-library/uf9938" target="_blank">thought-stopping technique.</a></p><p>"When the negative thoughts come or ruminations start, you say to yourself: 'Stop!,'" he says, adding that it is more effective when you actually say the word out loud.</p><p>He even recommends having a rubber band around your wrist to ping against yourself while saying the word. Adding a visual component by imagining a stop sign also makes the technique more powerful, he says.</p><p>The main idea here is conditioning yourself to stop the loop of worrying (making future predictions) or rumination (obsessing over past events).</p><p>Berger says the technique could take up to two weeks to take effect and that it needs to be practiced every day. "Consistency is very important," he says. </p>
Thoughts Are Just Thoughts<p>Another way of dealing with negative thoughts often used in modern therapy is realizing that thoughts aren't facts, says Berger.</p><p>He says it is important when we think something to ask: Is that real? Did that really happen? What is the worst thing that could happen?</p><p>Flight anxiety is one example where untrue thoughts are accepted as facts. Although air travel is the safest way to get around, people suffering from fear of flying accept their thoughts and fears as reality, then act upon them by refusing to fly.</p>
Mindfulness<p>Berger also recommends the use of mindfulness techniques, in which attention is paid to experiences in the moment without judging them, as a way of reducing worrying.</p><p>"Mindfulness helps you to distance yourself from your thoughts and to be more present in the moment," he says.</p><p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3432145/#R2" target="_blank">Several studies</a> have shown that mindfulness has a positive impact on reducing stress-related behaviors such as rumination and worrying, as focusing on the moment makes anxiety about other problems impossible.</p><p>Mindfulness can be practiced during routine activities by paying attention to your body and your surroundings. For instance, when you leave for work in the morning, you can focus on sensing the breeze, listen attentively to birds, feel the gravel under your feet and monitor your breath. </p>
Trick Your Brain Into Happiness<p>People plagued by obsessive thoughts do not always choose healthy ways like mindfulness to distract from them, however.</p><p> Dr. Edward Selby, a psychologist at Florida state university, has shown in a study that people try to avoid rumination by engaging in a range of uncontrolled behaviors, such as binge eating and substance abuse.</p><p>But he says that a much better way to overcome such distress is by distraction and shifting attention away from problems that are obsessing us.</p><p>There are many activities that can be used to distract from rumination, he says, and people should choose the one that works best for them. Here are some examples:</p><p>- Listen to music</p><p>- Read a book</p><p>- Take a hot shower</p><p>- Dance or exercise </p><p>- Talk to a friend (not about the problem)</p><p>- Watch a movie</p><p>- Mindfulness meditation</p>
Changing the Perception of Events<p>The way people perceive a situation largely influences their emotions and behavior. It is not the situation itself that determines how they feel, but rather the way they interpret it.</p><p>Reframing negative thoughts can lead to positive emotions and, subsequently, healthier behaviors — including a reduction in damaging overthinking and worrying.</p><p>Cognitive behavioral therapy (CBT) is currently a gold standard in psychotherapy. CBT aims to change the way people think and act. It largely involves challenging unhelpful beliefs or attitudes such as overgeneralization — thinking "I always fail at public speaking" when you have had one bad experience in front of an audience, for example — or "catastrophization," i.e., imagining the worst possible outcome to a situation. </p><p>A psychotherapist can teach people how to implement such thought-changing techniques into their lives. Techniques vary depending on their issues and goals.</p>
Solutions Are at Hand<p>Try to find ways of avoiding worrying, rumination and overthinking that make you feel most comfortable.</p><p>Incorporating any routine in your life when you're stressed isn't an easy task, but you can do it! If you feel overwhelmed, you can always seek professional help. </p><p><em>If you are suffering from serious emotional strain or suicidal thoughts, do not hesitate to seek professional help. You can find information on where to find such help, no matter where you live in the world, <a href="https://www.befrienders.org/" target="_blank">at this website.</a></em></p>

Getting Through the Pandemic<p>We have gained a much better understanding of COVID-19 over the past eight months. Without effective control measures, it is likely to continue to spread globally for many months to years, ultimately infecting billions and killing millions. The proportion of infected people who die appears to be <a href="https://www.medrxiv.org/content/10.1101/2020.05.03.20089854v4" target="_blank">slightly below 1%</a>.</p><p>This infection also causes serious <a href="https://www.bmj.com/content/370/bmj.m2815" target="_blank">long-term consequences</a> for some survivors. The largest uncertainties involve <a href="https://www.nature.com/articles/d41586-020-02278-5" target="_blank">immunity to this virus</a>, whether it can develop from exposure to infection or vaccines, and if it is long-lasting. The potential for treatment with antivirals and other therapeutics is also still uncertain.</p><p>This knowledge reinforces the huge benefits of sustaining elimination. We know that if New Zealand were to experience widespread COVID-19 transmission, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3310086/" target="_blank">impact on Māori and Pasifika populations</a> could be catastrophic.</p><p>We have previously described critical measures to get us through this period, including the use of fabric face masks, improving contact tracing with suitable digital tools, applying a science-based approach to border management, and the need for a dedicated national public health agency.</p><p>Maintaining elimination depends on adopting a highly strategic approach to risk management. This approach involves choosing an optimal mix of interventions and using resources in the most efficient way to keep the risk of COVID-19 outbreaks at a consistently low level. Several measures can contribute to this goal over the next few months, while also allowing incremental increases in international travel:</p><ul><li>resurgence planning for a border-control failure and outbreaks of various sizes, with state-of-the-art contact tracing and an upgraded alert level system</li><li>ensuring all New Zealanders own a <a href="https://www.nzma.org.nz/journal-articles/mass-masking-an-alternative-to-a-second-lockdown-in-aotearoa" target="_blank">re-useable fabric face mask</a> with their <a href="https://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=12354409" target="_blank">use built into the alert level system</a></li><li>conducting exercises and simulations to test outbreak management procedures, possibly including "mass masking days" to engage the public in the response</li><li>carefully exploring processes to allow <a href="https://blogs.otago.ac.nz/pubhealthexpert/2020/06/16/preventing-outbreaks-of-covid-19-in-nz-associated-with-air-travel-from-australia-new-modelling-study-of-alternatives-to-quarantine/" target="_blank">quarantine-free travel</a> between jurisdictions free of COVID-19, notably various Pacific Islands, Tasmania and Taiwan (which may require digital tracking of arriving travellers for the first few weeks)</li><li>planning for carefully managed inbound travel by key long-term visitor groups such as tertiary students who would generally still need managed quarantine.</li></ul>
Building Back Better<p>New Zealand cannot change the reality of the global COVID-19 pandemic. But it can leverage possible benefits.</p><p>We should conduct an <a href="https://blogs.otago.ac.nz/pubhealthexpert/2020/06/11/five-key-reasons-why-nz-should-have-an-official-inquiry-into-the-response-to-the-covid-19-pandemic/" target="_blank">official inquiry into the COVID-19 response</a> so we learn everything we possibly can to improve our response capacity for future events.</p><p>We also need to establish a specialized national public health agency to <a href="https://blogs.otago.ac.nz/pubhealthexpert/2017/12/20/the-havelock-north-drinking-water-inquiry-a-wake-up-call-to-rebuild-public-health-in-new-zealand/" target="_blank">manage serious threats to public health</a> and provide critical mass to <a href="https://blogs.otago.ac.nz/pubhealthexpert/2020/02/05/a-preventable-measles-epidemic-lessons-for-reforming-public-health-in-nz/" target="_blank">advance public health generally</a>. Such an agency appears to have been a key factor in the success of Taiwan, which avoided a costly lockdown entirely.</p><p>Business as usual should not be an option for the recovery phase. A recent <a href="https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=12353555" target="_blank">Massey University survey</a> suggests seven out of ten New Zealanders support a green recovery approach.</p><p>New Zealand's elimination of COVID-19 has drawn attention worldwide, with a description just <a href="https://www.nejm.org/doi/full/10.1056/NEJMc2025203" target="_blank">published</a> in the New England Journal of Medicine.

Anyone who's tending a garden right now knows what extreme heat can do to plants. Heat is also a concern for an important form of underwater gardening: growing corals and "outplanting," or transplanting them to restore damaged reefs.
