When we talk about rice, we mostly talk about white or brown. However, not many people know that there is a black-purple coloured variant of this called Black rice. Packed with nutrients, this variant owes its purple colour to a pigment called anthocyanin, which has potent antioxidant properties. Intrestingly, in ancient China, black rice was considered so unique and nutritious that it was forbidden for everyone beyond royalty.

What's Special About Black Rice?

1. A Rich Source of Essential Nutrients

A quarter cup (45 grams) of uncooked black rice provides:

Calories: 160

Fat: 1.5 grams

Protein: 4 grams

Carbohydrates: 34 grams

Fiber: 1 gram

Iron: 6% of the Daily Value (DV)

2. High in Antioxidants

Beyond its protein and fiber content, black rice is rich in antioxidants—compounds that help combat oxidative stress and reduce the risk of chronic diseases such as heart disease, Alzheimer’s, and cancer. Studies indicate that black rice has the highest antioxidant activity among rice varieties, containing over 23 beneficial plant compounds, including flavonoids and carotenoids.

3. Contains Anthocyanins for Added Health Benefits

Anthocyanins, the flavonoid pigments responsible for black rice’s dark hue, are known for their potent anti-inflammatory, antioxidant, and anticancer properties. Research suggests that consuming anthocyanin-rich foods can lower the risk of chronic diseases such as heart disease and obesity.

4. Supports Heart Health

Though research on black rice and heart health is ongoing, its flavonoids have been linked to a lower risk of cardiovascular disease. Some studies suggest that anthocyanins can improve cholesterol levels by increasing HDL (good) cholesterol and reducing LDL (bad) cholesterol. While further research is needed, early findings suggest black rice may help reduce plaque buildup in arteries.

5. Potential Anticancer Properties

Black rice’s anthocyanins may also play a role in cancer prevention. Population studies show that higher intake of anthocyanin-rich foods is associated with a reduced risk of colorectal cancer. Additionally, laboratory research suggests that anthocyanins from black rice can inhibit the growth and spread of breast cancer cells. However, more human studies are needed to confirm these effects.

6. Promotes Eye Health

Black rice contains significant amounts of lutein and zeaxanthin, two antioxidants that protect the eyes from damage caused by free radicals. These compounds help filter harmful blue light and may reduce the risk of age-related macular degeneration (AMD), cataracts, and diabetic retinopathy. Animal studies suggest anthocyanins may also protect the retina, though human research is still limited.

7. Naturally Gluten-Free

For individuals with celiac disease or gluten sensitivity, black rice offers a nutritious, gluten-free alternative to many whole grains. It provides essential nutrients without triggering digestive issues associated with gluten-containing grains like wheat, barley, and rye.

8. May Aid in Weight Management

Black rice’s high protein and fiber content can promote satiety, potentially aiding in weight management. Some animal studies suggest that anthocyanins may help reduce body fat, though human studies are still limited. A study found that consuming a mix of black and brown rice led to greater weight loss compared to eating white rice.

9. Additional Health Benefits

May Help Regulate Blood Sugar: Animal studies suggest that black rice may aid in blood sugar control, though human trials are required for confirmation.

Supports Liver Health: Research on mice indicates that black rice may reduce fat accumulation in the liver, potentially lowering the risk of non-alcoholic fatty liver disease (NAFLD).

10. Easy to Cook and Versatile

Cooking black rice is similar to preparing other rice varieties. Simply combine the rice with water or broth, bring it to a boil, then reduce the heat and let it simmer for 30–35 minutes until tender. To achieve a fluffier texture, rinse the rice before cooking to remove excess starch.

Black rice can be used in various dishes, including grain bowls, stir-fries, salads, and desserts like rice pudding.

Your adolescence lasts well up to your 30s. A new, "cool" study as Prof Tara Spires Jones, tells BBC, noted that the human brain does not follow a simple, steady path from birth to old age. Instead, it moves through five clear phases, each marked by a shift in how its networks connect and communicate. The study is conducted by the researchers from the University of Cambridge, who analyzed thousands of brain scans to track how neural connections strengthen, weaken, and reorganize over time.

This large study involved nearly 4,000 people between infancy and age 90 and has now mapped these transitions, offering new insights into why periods of life differ so much in terms of learning, behaviors, and vulnerability to mental health conditions.

Their work shows that the brain remains in an adolescent state far longer than earlier believed and reaches a peak of efficiency only in the early thirties. The findings, published in Nature Communications, highlight striking turning points at the ages of nine, 32, 66 and 83.

The Five Phases Of Brain

Childhood: Birth to Age Nine

The study showed that during childhood, the brain grown rapidly, however, it also begins trimming the vast numbers of synapses formed in early life. This is what helps the brain decide which pathways truly matter. However, this period is not very efficient. It resembles a child wandering without a fixed route, exploring freely rather than moving directly from one point to another. The purpose is exploration, not precision.

Adolescence: Age Nine to 32

A dramatic shift begins around age nine. The brain enters a long stretch of heightened efficiency as it reorganizes its neural networks with remarkable speed and intensity.

This is the phase where mental health vulnerabilities often emerge, since the brain is restructuring at an unusually rapid pace.

This part of the study also breaks the conventional idea that associated adolescence typically with the teenage years. Modern neuroscience suggests it extends into the twenties. This study pushes that boundary even further, indicating that the adolescent phase may last all the way to 32.

During this time, the brain reaches its most efficient point, and many cognitive abilities are thought to peak.

Adulthood: Age 32 to 66

After the long adolescent stretch, adulthood brings stability. The study shows that adulthood actually comes from the age 32, again a shift from what conventionally was believed adulthood to be. This is the brain’s most settled era, lasting more than three decades. Change continues, but at a gentler pace and in a more predictable pattern. The efficiency gained earlier begins to level out. Many people recognize this phase as a period when their cognitive strengths, personality and sense of self feel most consistent. The fireworks of earlier development give way to a steady rhythm.

Early Aging: Age 66 to 83

The period after 66 marks the beginning of early ageing. It does not arrive as a sudden decline. Instead, there are subtle shifts in how different parts of the brain coordinate.

Rather than functioning as one unified network, the brain begins to break into clusters of regions that work more closely within their own groups. It is similar to a band whose members start pursuing individual projects while still occasionally performing together.

Although the study focused on healthy brains, this is also the age when conditions linked to ageing, such as high blood pressure and dementia, begin to appear more frequently.

Late Aging: 83 And Beyond

The final phase begins at around 83. Data for this group was more limited, since it is harder to find older adults with no underlying health issues. Even so, the scans show that the patterns seen in early ageing become more pronounced. The brain’s networks continue to drift apart, and communication between regions becomes less synchronized.

As of 8.30 am, the pollution levels in New Delhi stood at the AQI of 293, according to aqi.in, which is equivalent to smoking 8.9 cigarettes per day, 62.3 cigarettes per week, and around 267 cigarettes per month, based on the average PM2.5 concentration over the last 24 hours.

While GRAP measures have been implemented in Delhi, there are still a section of people who continue to step out for work and other chores. From time and again experts, doctors, and researcher have pointed out the negative health impact the pollution bears on people. It is no longer limited to lungs or respiratory issues, but goes much beyond it. Ambient air pollution is responsible for fertility issues, bone health, and even cognitive risks like dementia, and more.

However, there is another health risk that people did not know can be impacted by pollution. It is your blood health or blood function.

What Is Blood Health?

Blood health refers to blood's ability to perform its vital functions, which includes transporting oxygen, nutrients, fighting infections, and regulating body temperature. Unhealthy blood could lead to disorders like anemia, blood clots, or even blood cancer.

How Does Air Pollution Impact Blood Health?

As per a 2024 study published in the journal BMC Public Health, titled Association of Ambient Air Pollution With Hemoglobin Levels and Anemia In The General Population of Korean Adults noted the detrimental effects of air pollution exposure on hemoglobin concentrations and anemia in specific populations, which included children, pregnant women, and the elderly.

The study noted that the pollutants in the air contributes to disturbances in iron homeostasis, thus the exposure to air pollution leads to cellular iron deficiency through the activation of oxidation production. It also increases secretion of pro-inflammatory mediators. This pro-inflammatory cytokines that are now increased cause a deficiency erythropoietin secretion, resulting in anemia.

In addition, exposure to air pollution increases the secretion of reactive oxygen species, resulting in oxidative stress. In 2008, an experimental study in a murine model reported that oxidative stress was closely related to iron deficiency anemia.

Another advisory from 2024, published in the National Institute of Health's (NIH) official website states that long term exposure to air pollution is linked to blood clots in veins that bring blood to the heart. The study was published by NIH, which included 6,651 US adults who were followed for an average 17 years between 2000 and 2018. Throughout the study, 284 adults developed blood clots in deep veins. Whereas 89% to a more than two-fold increases risk based on long term exposure was also noted for those who lived near polluted areas.

"Exposure to air pollution, which can set the stage for inflammation and contribute to blood clotting, has long been associated with cardiovascular and respiratory diseases. While previous research has also suggested a link to VTE, this is the largest, most comprehensive U.S. study to report that association with three different types of air pollutants," the advisory read.

The pollutants included particulate matter, which are tiny particles equal to or less than 2.5 micrometers, which can be inhaled easily, and can penetrated through every organ, and enter your blood streams.

Furthermore, pollutants like PM2.5 and PM10, benzene, polycyclic aromatic hydrocarbons and heavy metals like arsenic and lead could also be absorbed into the lungs and passed to blood streams. These trigger oxidative stress, DNA damage and inflammatory responses, all of which contribute to abnormal cell growth and mutations in blood cells. A comprehensive review published by the World Health Organization (WHO) suggested that this exposure could also increase the risk of blood cancer by 15 to 40% in people, depending on the exposure of pollution.

If screening is made available and accessible to those between 40 to 85 years of age, it could detect 94% of lung cancers. Even if 30% of people get screened, it could prevent 26,000 deaths in the US. Despite that, the screening for the deadliest cancer in the US still misses most cases, reveals a JAMA Network study. As per the American Cancer Society, 226,650 new cases of lung and bronchus cancer in 2025, the Centers for Disease Control and Prevention (CDC) notes 18,893 new cases in 2022. As for deaths, the American Cancer Society estimates around 124,730 lung cancer deaths in 2025.

The Washington Post reports that when a 42-year-old mother of three, Jessie Creel first developed a stubborn cough in May last year, she did what most people would do. She went to her doctor, took the prescribed antibiotics and hoped to bounce back quickly. Instead, her cough worsened. She began losing weight, struggled to sleep and even coughed up blood during a camping trip. Nothing about it felt normal anymore.

Six months later, she was diagnosed with Stage 4 lung cancer. Creel ran, swam, avoided alcohol and had never smoked, yet her cancer had spread to her bones, brain and lymph nodes by the time it was detected. Her story is becoming more familiar among cancer specialists, who now say lung cancer is no longer a disease that fits the old stereotype of the heavy smoker. The JAMA Network study is pushing experts to ask whether current lung cancer screening guidelines are excluding thousands of people who might benefit from early detection.

The Current Screening Rules That Limits People From Getting Themselves Screened

Right now, lung cancer screening in the United States is recommended only for people between 50 and 80 who have a heavy smoking history and who either still smoke or quit within the last 15 years. However, the researchers of the new study examined around 1000 lung cancer patients treated at Northwestern Medicine. Only one third would have qualified for screening under today’s guidelines. Women, people of color and those who had never smoked made up a large portion of the patients who fell outside the criteria.

According to the study’s authors, this means most lung cancer cases in the country are detected only after symptoms appear, which often happens when the cancer has already advanced.

Experts suggest a broader, age based approach similar to breast or colon cancer screening. If everyone between 40 and 85 could get screened, researchers estimate that nearly 94 percent of lung cancer cases could be identified, potentially preventing more than 26,000 deaths each year even if only a fraction of eligible people participated.

How Is Lung Cancer Detected?

For those who qualify, lung cancer screening is done using a low dose CT scan once a year. These scans use far less radiation than a regular CT and have been shown to catch cancers early.

The U.S. Preventive Services Task Force guidelines decide who gets insurance covered screening. The American Cancer Society has its own recommendation, which is slightly more flexible but does not guarantee full coverage.

Doctors say that when lung cancer is caught early through screening, cure rates can exceed 90 percent. But many people who do not meet today’s criteria never get that chance and are often diagnosed only once symptoms set in. By that stage, treatment is more complex and outcomes are less optimistic.

Why Are Experts Asking For A Change In System?

Lung cancer remains the leading cause of cancer related deaths. It kills more people than breast, colon and prostate cancers combined. Yet smoking rates have dropped significantly over the years, which means screening based on smoking history alone no longer reflects who is actually getting sick.

The new study suggests that continuing with the current guidelines would mean detecting only one third of new cases. Experts call the findings alarming and believe shifting to an age based model could save more lives than the number of people who die each year from brain cancer.

Broader screening may also reduce long term healthcare costs. Detecting cancer at Stage 1 rather than Stage 4 could save nearly 25 billion dollars annually in treatment expenses, far outweighing the cost of offering more people access to scans.
