  • Is Brown Rice Healthier? Study Finds It Contains 40% More Carcinogenic Arsenic

    Is Brown Rice Healthier? Study Finds It Contains 40% More Carcinogenic Arsenic

    Thinking of switching to brown rice for its added nutrients? You may want to think again.

    While the bran layer does pack in more vitamins and minerals, researchers now warn that brown rice contains up to 40% more carcinogenic arsenic than white rice.

    In a recent study published in the journal Risk Analysis, researchers from Michigan State University conducted a comparative analysis of brown and white rice, factoring in cost, popularity, health benefits, and potential risks.

    Their findings revealed a surprising hidden danger: brown rice contained 24% more total arsenic and about 40% more inorganic arsenic (known carcinogen), raising fresh concerns about its reputation as the healthier choice.

    In their comparative analysis, researchers highlighted that brown rice offers notable nutritional benefits, including higher levels of vitamins, minerals, fiber, and antioxidants. It has been associated with reduced risks of cancer, lower cholesterol levels, improved blood pressure, and support for heart health, metabolic disorders, osteoporosis, and diabetes.

    However, these health benefits come with significant trade-offs. Brown rice tends to be more expensive, and less appealing in taste and texture for some consumers, and most importantly, it carries a higher risk of arsenic exposure, linked to genetic damage and an increased risk of cancer.

    Meanwhile, white rice presents a more affordable and widely accepted option, appealing to a broader range of consumers across different cultures. Its processing removes much of the arsenic-laden outer layers, resulting in significantly lower levels of both total and inorganic arsenic. However, this also strips away key nutrients, leading to reduced levels of vitamins, minerals, fiber, and other beneficial compounds compared to brown rice.

    The researchers also noted that since young children consume considerably more food relative to their body weight than adults, brown rice consumption in young children can increase their foodborne arsenic exposures. Given this concern, they recommend that parents consider balancing brown and white rice in young children’s diets to minimize potential health risks while still providing nutritional benefits.

    “However, there are no acute public health risks indicated for the general American population from rice-related arsenic exposures. Risk–benefit analyses are needed to assess relative risks of arsenic exposure in brown rice compared with the nutritional benefits, in comparison to white rice,” the researchers concluded.

  • Foreigners in Vietnam Prioritise Doctor Expertise When Choosing Healthcare, Survey Finds

    Foreigners in Vietnam Prioritise Doctor Expertise When Choosing Healthcare, Survey Finds

    When selecting healthcare services in Vietnam, foreign residents prioritize the expertise of medical professionals, according to findings from a newly released survey.

    The survey by Indochina Research Vietnam Ltd. highlights key insights into the healthcare preferences of foreigners living in major cities like Hanoi, Ho Chi Minh City, Da Nang, and Can Tho. Vinmec, a leading private hospital chain in Vietnam, leads in brand awareness, with most respondents identifying it as their preferred healthcare provider.

    “This first survey serves as a valuable resource for healthcare institutions in Vietnam, offering them critical data on the needs, expectations, and feedback on past experiences of foreign residents in healthcare facilities in four key cities.” said Xavier Depouilly, General Director of Indochina Research Vietnam.

    The survey was conducted over two months in early 2025 across key urban districts in Hanoi, Ho Chi Minh City, Da Nang, and Can Tho. Using a mix of face-to-face and online surveys, the research gathered insights from foreign nationals aged 18 and above who had used or been aware of medical facilities in Vietnam.

    In Hanoi and Ho Chi Minh City, participants needed three months’ residency in Vietnam and intent to stay six more. In Da Nang and Can Tho, respondents were required to have lived in Vietnam for at least one month, with plans to stay for a further six months.

    According to the study, 80% of respondents in Hanoi, 71% in Ho Chi Minh City, and 78% in Da Nang are familiar with Vinmec’s services, placing the hospital at the top of awareness charts across all surveyed cities. Family Medical Practice, Hanoi French Hospital, and FV Hospital are other top healthcare facilities identified in the survey.

    Among factors influencing healthcare choices, foreigners in Vietnam prioritize doctors’ expertise (53%), followed by the availability of advanced medical equipment (48%) and the quality of patient care or empathy (40%). These preferences remain consistent across cities, although location-specific preferences are evident.

    Within the last two years, 88% of expatriates have engaged with healthcare facilities in Vietnam, predominantly for individual health concerns. Services most often sought include routine health assessments (48%), dental treatments (39%), and standard medical advice (38%). On the other hand, cosmetic enhancements and mental health support are rarely utilized or relied upon, with a mere 3% participation rate.

    Looking ahead, 87% of respondents plan to use medical services in Vietnam within the next 6-12 months. Dental care (59%) and health check-ups (58%) are the most anticipated services.

    For adult treatments, Vinmec is consistently ranked as the top choice across all regions. Meanwhile, when it comes to pediatric care, Family Medical Practice takes the lead.

    For emergency care, preferences vary by city. Vinmec and the FV Hospital are top picks in Hanoi and Ho Chi Minh City respectively. Vinmec is the first choice in Danang, while foreigners in Can Tho prefer the Can Tho University of Medicine as their top option.

    As Vietnam continues to grow as a hub for international business and medical tourism, understanding the healthcare preferences of foreign residents is crucial.
    Xavier emphasized: “We hope these findings will contribute to improving the quality and breadth of healthcare services for expatriates and their families and, in turn, foster the development of medical services in Vietnam.”

  • Vaping Affects Circulation With Immediate Effects, Study Finds

    Vaping Affects Circulation With Immediate Effects, Study Finds

    Vaping is often promoted as a safer alternative to cigarette smoking. But is using e-cigarettes truly risk-free? Researchers have discovered that vaping impacts circulation, with noticeable effects occurring immediately.

    In the latest study that will be presented at the annual meeting of the Radiological Society of North America (RSNA) next week, researchers explored the impact of both cigarette smoking and vaping on vascular function. The study found that while vaping exposes users to fewer toxic chemicals than cigarettes, it still affects circulation and overall health. Interestingly, the effect was observed even in e-cigarettes without nicotine.

    “E-cigarettes have long been marketed as a safer alternative to regular tobacco smoking. Some believe that e-cigarettes don’t contain any of the harmful products, such as free radicals, found in regular tobacco cigarettes, because no combustion is involved,” said Dr. Marianne Nabbout, the study lead author in a news release.

    To assess the impact on brain circulation, researchers evaluated 31 healthy participants—both smokers and vapers—using MRI scans before and after exposure to tobacco cigarettes, e-cigarette aerosol with nicotine, and e-cigarette aerosol without nicotine. The participants, aged 21 to 49, were compared to baseline scans from 10 non-smokers and non-vapers, aged 21 to 33.

    The study also measured blood flow speed in the femoral artery by placing a cuff on the upper thigh to restrict circulation. Also, the venous oxygen saturation of the participants, which shows the amount of oxygen in the blood returning to the heart after supplying oxygen to the body’s tissues was tested.

    After inhaling each type of vaping or smoking, blood flow in the superficial femoral artery significantly decreased. The greatest decrease in vascular function occurred after vaping e-cigarettes with nicotine, followed by those without nicotine. Vapers also showed lower venous oxygen saturation, indicating an immediate reduction in oxygen uptake by the lungs, regardless of nicotine content.

    “This study serves to highlight the acute effects smoking and vaping can have on a multitude of vascular beds in the human body. If the acute consumption of an e-cigarette can have an effect that is immediately manifested at the level of the vessels, it is conceivable that the chronic use can cause vascular disease,” Dr. Nabbout said.

  • Cardiovascular Fitness May Lower Dementia Risk, Even For Those With Genetic Predisposition, Study Finds

    Cardiovascular Fitness May Lower Dementia Risk, Even For Those With Genetic Predisposition, Study Finds

    Regular exercise is known to prevent chronic conditions and slow cognitive decline. New research suggests that cardiovascular fitness, the body’s ability to deliver oxygen to muscles during exercise, could also play a crucial role in reducing dementia risk.

    A recent study found that improved cardiorespiratory fitness is linked to better cognitive performance and a lower risk of dementia, even among those genetically predisposed.

    As people age, cardiovascular fitness typically declines by 3% to 6% every decade in their 20s and 30s. However, this decline accelerates to over 20% per decade once individuals reach their 70s. With reduced fitness, there is an increased risk of cardiovascular events such as strokes and heart attacks and mortality from all causes, according to the researchers of the latest study.

    The study evaluated 61,214 participants between the ages of 39 and 70 enrolled in the UK Biobank study between 2009 and 2010. The participants did not have dementia and were followed for up to 12 years.

    The researchers assessed the cardiorespiratory fitness of participants at the beginning of the study by conducting a 6-minute submaximal exercise test on a stationary bike. While neuropsychological tests were used to evaluate cognitive function, the participant’s genetic predisposition for dementia was estimated using the polygenic risk score.

    During the follow-up, 553 people were diagnosed with dementia. Based on the cardiorespiratory fitness scores, the participants were divided into three equal-sized groups standardized by age and sex.

    The analysis revealed that people with higher fitness scores were 40% less likely to develop dementia than those with lower scores. Also, dementia onset was delayed by nearly 1.5 years for those with high scores.

    The researchers noted that in those with a moderate to high genetic risk of dementia, high cardiovascular fitness reduced their risk of developing dementia by 35%.

    Since the study is observational, the researchers could not establish a direct cause-and-effect relationship. They noted some limitations, including the potential underestimation of dementia cases, as UK Biobank participants are healthier than the general population. Individuals with certain health conditions were excluded from the exercise test, making the study group healthier which may have impacted the findings.

    However, based on the current findings, the researchers suggest that “enhancing CRF could be a strategy for the prevention of dementia, even among people with a high genetic predisposition for Alzheimer’s disease.”

  • Study Finds Two Common Gynecological Disorders Linked To Increased Risk Of Early Death

    Study Finds Two Common Gynecological Disorders Linked To Increased Risk Of Early Death

    History of two common gynecological disorders, endometriosis and uterine fibroids, is linked to an increased risk of early death, a recent study revealed.

    Endometriosis is a chronic reproductive disorder that affects about 10% of women of reproductive age. It occurs when tissue similar to the uterine lining grows outside the uterus, causing symptoms such as severe period pain, chronic pelvic pain, bloating, nausea, fatigue, and infertility. There is no permanent cure for the condition, so treatment involves managing symptoms.

    Fibroids are noncancerous growths on uterine walls that can cause symptoms such as heavy menstrual bleeding, back pain, and frequent urination. Around 40% to 80% of women have uterine fibroids.

    In a large-scale study, researchers analyzed 110,091 women from the Nurses’ Health Study II, aged 25-42 in 1989. The participants had no prior hysterectomy, cardiovascular diseases, or cancer. Diagnoses of endometriosis (via laparoscopy) and fibroids (via ultrasound or hysterectomy) were self-reported every two years from 1993.

    Over 30 years, there were 4,356 premature deaths, including 1,459 from cancer and 304 from cardiovascular diseases.

    The all-cause premature death rate for women with confirmed endometriosis was 2 per 1,000 person-years, compared to 1.4 per 1,000 for those without. After accounting for factors such as age, weight, diet quality, physical activity, and smoking status, individuals with endometriosis were 31% more likely to die prematurely (before age 70) compared to those without these disorders. The majority of these deaths were attributed to gynecological cancers.

    Although uterine fibroids were not linked to all-cause premature death, the condition elevated the risk of death due to gynecological cancers.

    “Women with a history of endometriosis and uterine fibroids might have an increased long-term risk of premature mortality extending beyond their reproductive lifespan,” the researchers concluded.

    “These conditions were also associated with an increased risk of death due to gynecological cancers. Endometriosis was associated with a greater risk of non-cancer mortality. These findings highlight the importance for primary care providers to consider these gynecological disorders in their assessment of women’s health,” they wrote in the study published in the journal BMJ.

    The researchers caution that since it is an observational study relying on self-reported data, it can be prone to errors. Also, as the participants were predominantly white healthcare workers, the findings may not be generalizable to other populations.

  • Poor Sleep In 40s May Add Years To Your Brain Age: Study Finds

    Poor Sleep In 40s May Add Years To Your Brain Age: Study Finds

    Missing out on sleep not only makes you feel groggy the next day, but the effects can be long-lasting. Adding to the growing body of evidence, researchers have now found that poor sleep in the middle ages is linked to accelerated brain aging in the next ten years.

    The latest study that evaluated participants’ brain health using brain scans revealed that having poor sleep quality in the 40s might add more years to the brain age.

    “Sleep problems have been linked in previous research to poor thinking and memory skills later in life, putting people at higher risk for dementia. Our study which used brain scans to determine participants’ brain age, suggests that poor sleep is linked to nearly three years of additional brain aging as early as middle age,” said study author, Clémence Cavaillès from the University of California San Francisco in a news release.

    The researchers evaluated the sleep patterns of 589 participants with an average age of 40 using questionnaires at the start of the study and five years later. After 15 years, the researchers evaluated the brain shrinkage of the participants using brain scans.

    The questionnaires evaluated participants based on six sleep issues: difficulty falling asleep, waking up in between sleep, waking up too early, short sleep duration, bad sleep quality, and daytime sleepiness.

    Based on the results, participants were divided into three groups according to their sleep quality. Those in the low group had just one poor sleep characteristic and 70% belonged to this group. However, the middle group, comprising 22% of participants, had two to three poor sleep features, while the high group, with more than three poor sleep characteristics, made up 8% of the population.

    After analyzing brain scans alongside sleep patterns, researchers found that participants in the middle group had an average brain age of 1.6 years older than those in the low group. Meanwhile, those in the high group showed an average brain age of 2.6 years older than the low group.

    Out of the six poor sleep characteristics studied, bad sleep quality, difficulty falling asleep, difficulty staying asleep and early morning awakening were linked to greater brain age. This was particularly strong when the participants consistently had it for over five years.

    “Our findings highlight the importance of addressing sleep problems earlier in life to preserve brain health, including maintaining a consistent sleep schedule, exercising, avoiding caffeine and alcohol before going to bed and using relaxation techniques,” said author Dr. Kristine Yaffe, from the University of California San Francisco.

  • No Cardiovascular Benefits, Raises Circulatory Risks; Study Finds

    No Cardiovascular Benefits, Raises Circulatory Risks; Study Finds

    Sitting for extended periods has long been linked to various health risks including cardiovascular issues, driving the popularity of standing desks among office workers. However, a recent study suggests that standing for extended periods offers no long-term cardiovascular benefits and may not be the better option.

    According to the latest study published in the International Journal of Epidemiology, standing for long periods may not benefit heart health and could increase the risk of circulatory problems, such as deep vein thrombosis and varicose veins.

    Researchers from the University of Sydney analyzed heart conditions and circulatory disease data from 83,013 UK adults, collected over seven to eight years. These participants, who did not have any heart disease at the start, were monitored using wrist-worn wearables similar to smartwatches to track their activity and health.

    The analysis revealed that for every additional 30 minutes spent standing beyond two hours, the risk of circulatory disease increased by 11 percent.

    “The key takeaway is that standing for too long will not offset an otherwise sedentary lifestyle and could be risky for some people in terms of circulatory health. We found that standing more does not improve cardiovascular health over the long-term and increases the risk of circulatory issues,” Dr Matthew Ahmadi, the lead author of the study said in a news release.

    The researchers also found that sitting for more than 10 hours a day raises the risk of both cardiovascular disease and orthostatic issues.

    Based on these findings, the researchers recommend that people who are regularly sedentary or stand for extended periods incorporate regular movement throughout the day to mitigate these risks.

    “For people who sit for long periods on a regular basis, including plenty of incidental movement throughout the day and structured exercise may be a better way to reduce the risk of cardiovascular disease,” said Professor Emmanuel Stamatakis, Director of the Mackenzie Wearables Research Hub.

    “Take regular breaks, walk around, go for a walking meeting, use the stairs, take regular breaks when driving long distances, or use that lunch hour to get away from the desk and do some movement,” Stamatakis said.

    Earlier research by the team found that just 6 minutes of vigorous exercise or 30 minutes of moderate-to-vigorous exercise per day can reduce the risk of heart disease, even in individuals who are highly sedentary for over 11 hours a day.

  • Secret To Cholesterol Control? Study Finds Corn Flour Blend Could Be A Game Changer

    Secret To Cholesterol Control? Study Finds Corn Flour Blend Could Be A Game Changer

    Yes, you can control your cholesterol levels through diet, but could it be as simple as adding a corn flour blend to your meals for just a few weeks? Researchers have found that incorporating a blend of refined corn flour and corn bran can reduce LDL (low-density lipoprotein) cholesterol levels by 5% to 13.3% in just four weeks.

    In a clinical trial involving 36 adults with LDL cholesterol above 110 mg/dL, researchers evaluated the consumption of three types of corn flour: whole-grain corn meal, refined corn meal, and a blend (refined corn meal plus corn bran). The participants took each food intervention for four weeks, with at least a two-week break in between, before returning to their baseline.

    At the end of the four weeks, the team found that 70% of the participants had reductions in LDL cholesterol concentrations when consuming the blend, while there were no reductions in other groups. The findings were published in the Journal of Nutrition.

    The researchers provided participants with corn flour incorporated into baked goods, aiming to test a practical and realistic intervention.

    “People often think that dietary changes must be robust and significant to have a real impact on cardiovascular health and metabolic regulation. The bottom-line is this: corn is unique and underappreciated. The art and science of refining grains and making full use of corn bran can result in delicious foods that, in this case, also happen to produce real results for heart health,” Corrie Whisner, a researcher from the Arizona State University, said in a news release.

    The researchers noted that there were no digestive discomforts for any participants during the interventions, indicating that there was no significant change in gut microbiota. However, they found an increase in gut bacteria- Agathobaculum during the phase in which participants had whole-grain corn, but not in the other two groups.

    “The increase in Agathobaculum could be due to the greater diversity of polyphenols found in whole grain corn, which has the highest antioxidant capacity (compared to wheat, oats, and rice), but the study did not analyze this possibility,” Whisner said.

    “Nevertheless, while the influence of whole grains on the microbiota varies from person-to-person, some universals are generally known fibers in whole grains can be fermented by microbes into butyrate, and both fiber and butyrate are frequently associated with a healthy gut. These findings support that understanding,” Whisner added.

  • Cutting Out This Item From Your Diet Could Reverse Aging, New Study Finds

    Cutting Out This Item From Your Diet Could Reverse Aging, New Study Finds

    Your health isn’t solely influenced by what you eat but also by what you cut off from your diet. Researchers have now identified a specific item in your daily diet that, when reduced, could potentially reverse the signs of aging.

    Fruits, veggies, and a diet rich in vitamins and minerals are all essential for healthy aging. However, a recent study identified that even when people ate healthy diets, each gram of added sugar could increase their biological age.

    The study published in Jama Network Open examined the link between added sugar and epigenetic aging, which assesses an individual’s aging through DNA methylation patterns. The findings revealed that cutting back on sugar had a profound effect, potentially reversing biological aging at the cellular level.

    “We knew that high levels of added sugars are linked to worsened metabolic health and early disease, possibly more than any other dietary factor. Now we know that accelerated epigenetic aging is underlying this relationship, and this is likely one of many ways that excessive sugar intake limits healthy longevity,” said study co-senior author Elissa Epel in a news release.

    Co-senior author Barbara Laraia said, “Given that epigenetic patterns appear to be reversible, it may be that eliminating 10 grams of added sugar per day is akin to turning back the biological clock by 2.4 months, if sustained over time. Focusing on foods that are high in key nutrients and low in added sugars may be a new way to help motivate people to eat well for longevity.”

    The study examined dietary records of 342 Black and white women with a mean age of 39 years in Northern California. To understand their epigenetic scores, they assessed the saliva samples of the participants, which were then compared against the dietary records.

    The researchers also compared the diet scores of the participants against a Mediterranean-style diet rich in anti-inflammatory and antioxidant foods and a diet linked to reduced risk for chronic disease.

    Finally, they evaluated the diets using the “Epigenetic Nutrient Index (ENI),” which measured nutrients linked to anti-oxidative or anti-inflammatory processes and DNA maintenance and repair. The results suggest that adherence to all diets rich in Vitamins A, C, B12, and E, folate, selenium, magnesium, dietary fiber, and isoflavones was associated with a lower epigenetic age. However, the strongest association was seen with the Mediterranean diet.

    The researchers came across a key finding: consuming foods with added sugar was linked to accelerated biological aging, even if the rest of the diet was healthy.

    “The diets we examined align with existing recommendations for preventing disease and promoting health, and they highlight the potency of antioxidant and anti-inflammatory nutrients in particular. From a lifestyle medicine standpoint, it is empowering to see how heeding these recommendations may promote a younger cellular age relative to chronological age,” said Dorothy Chiu, the first author of the study.
