Hoi khom, the humble freshwater snail with a spiral shell, thrives in the nutrient-rich waters of Thai rice paddies and wetlands. In Thailand and Southeast Asia, this small creature is more than food; it sits at the intersection of culinary tradition, folklore, and folk medicine. Today’s examination asks: what does science say about hoi khom’s healing claims, and how can this rural lifeline connect to contemporary research and Thai realities?

Recent research has highlighted potential heart risks associated with the use of marijuana and other THC-containing products. This warning comes as the popularity of cannabis continues to rise globally, including in parts of Asia, where regulatory discussions and policy shifts are increasingly advocating for medical and recreational access. Understanding these health implications is crucial, especially for a nation like Thailand, which recently made significant changes to its cannabis policies with the decriminalization of the plant.

A new study points to omega-3 fatty acids as a potential tool to support longevity and overall health in seniors. The DO-HEALTH trial, conducted in Switzerland, explored whether daily omega-3 intake could slow biological aging in adults aged 70 to 85. Participants received a 1-gram omega-3 supplement daily alongside vitamin D, while others followed an at-home exercise program.

Over three years, researchers found that those taking omega-3 showed slower progression of aging markers. The results suggested a rejuvenation effect of about three to four months. Additionally, the data indicated a reduced risk of cancer by about 61 percent and a lower chance of pre-frailty by 39 percent—conditions that often precede frailty in later life.

In a compelling development for those seeking to extend their lifespan, recent research has highlighted the potential of a common supplement to improve longevity and overall health. Omega-3 fatty acids, widely known for their benefits to brain and heart health, may also play a significant role in slowing down the biological aging process. This discovery comes from a comprehensive study conducted in Switzerland, known as the DO-HEALTH trial, which investigated the effects of omega-3 on individuals between the ages of 70 and 85.

A century of life can hinge on straightforward choices. Dr. John Scharffenberg, a 101-year-old adjunct professor at Loma Linda University’s School of Public Health, champions a simple, actionable approach to health. He credits longevity to daily habits rather than genetics, noting that his parents died from cardiovascular and neurological conditions in later years.

Thailand and much of Southeast Asia are witnessing rising life expectancy, alongside growing challenges from non-communicable diseases. Scharffenberg’s guidance arrives at a crucial moment. He argues that preventing cardiovascular disease is achievable through lifestyle changes, a view supported by health authorities worldwide. His seven lifestyle tenets are shared through lectures and digital platforms focused on longevity.

New studies suggest potential heart risks from using marijuana and other THC-containing products. As cannabis policies evolve globally, including in parts of Asia, Thai readers should understand how these findings may relate to personal health and public policy. Thailand recently relaxed cannabis rules for medical and economic reasons, making clear, balanced information even more important.

Research indicates that THC, the main psychoactive component of cannabis, may raise the risk of cardiovascular events such as irregular heart rhythms, heart attacks, and strokes. This aligns with broader evidence that cannabis can influence heart rate, blood pressure, and overall heart health. Given that heart disease remains a leading cause of death in Thailand, these insights carry particular relevance for local audiences.

The threat of measles is looming larger than ever with rising unvaccination rates posing significant public health risks worldwide. An enlightening report by The New York Times describes the grim reality of measles infection, specifically targeting unvaccinated children. Given the highly infectious nature of this virus, the findings are particularly poignant for Thailand, where vaccination campaigns have been critical in the past.

Measles, known as one of the most infectious viruses globally, requires no direct contact to spread. A simple stroll through a room where an infected individual was present could lead to transmission through inhaled droplets. The report highlighted that 90% of unvaccinated individuals exposed to measles will contract it. For Thailand, where public spaces such as markets and schools are pivotal in daily life, understanding this transmission dynamic is crucial in preventing outbreaks.

Recent research on dietary fiber suggests that psyllium husk, a well-known supplement for digestive health, could also play a crucial role in improving brain function. As only about 5% of the U.S. population consumes the recommended amount of fiber, this revelation could prompt many, including those in Thailand, to rethink their daily fiber intake.

Fiber has long been celebrated for its ability to improve bowel regularity and, more recently, for its role in weight management, particularly amidst the popularity of weight loss aids like Ozempic. The current buzz around psyllium husk is due to findings that suggest it may support not just physical health, but cognitive function as well.

World Health Day on April 7, 2025, highlights the path to lifelong health through early childhood nutrition under the theme “My Health, My Right.” The focus is on equitable access to essential healthcare and nourishment for every child, regardless of family income. Good nutrition in a child’s first years significantly shapes growth, immunity, and cognitive development, influencing health well into adulthood.

Nutrition in the early years is a keystone of well-being. In the first five years, the brain develops rapidly, making balanced intake of key nutrients crucial. A senior pediatric specialist notes that poor nutrition can cause stunted growth and slower cognitive development, increasing the risk of chronic diseases later in life.

In a groundbreaking study published in Epidemiology and Psychiatric Sciences, researchers have found that individuals who experience social disconnectedness face significantly higher risks of various medical conditions. This study, conducted by Lisbeth Mølgaard Laustsen and colleagues, reveals that loneliness, social isolation, and lack of social support—the three core measures of social disconnectedness—are linked to an increase in illnesses, impacting almost all major health categories (source).

This research is critical for Thai readers who can draw parallels with societal changes in Thailand, where urbanization often leads to reduced family time and a potential for increased social isolation. The study, utilizing data from the Danish National Health Survey, covered 162,604 participants and assessed social connections using tools like the Three-Item Loneliness Scale. The findings indicate that lonely individuals were at greater risk across 11 medical conditions, notably mental disorders and dementia, with loneliness being more influential than social isolation or low social support.

In an intriguing development, scientists are uncovering the intricate workings of the brain that signal when we need to eat or drink. A recent study conducted by the Max Planck Institute for Biological Intelligence, in collaboration with the University of Regensburg and Stanford University, has found critical insights into how specific neurons within the brain’s amygdala may drive our basic urges to eat and drink. This discovery not only adds depth to our understanding of these essential functions but also opens new avenues for tackling conditions like obesity, anorexia, and even addiction.

A recent scientific discovery sheds light on how our brains signal when to eat or drink. Researchers from the Max Planck Institute for Biological Intelligence,Working with the University of Regensburg and Stanford University, have identified specific neurons in the amygdala that influence these basic urges. The findings could deepen our understanding of eating disorders, obesity, and addiction, while guiding better health strategies for Thailand’s growing health challenges.

In a study conducted with mice, researchers found distinct neuron groups within the amygdala that play separate roles in hunger and thirst. The amygdala is known for processing emotions and motivations, but this research highlights its involvement in core survival drives. According to senior researchers, manipulating particular neurons altered drinking behavior and pinpointed a neuron group linked to thirst regulation. Some neurons showed overlapping functions, affecting both thirst and hunger.

Measles remains highly contagious, and unvaccinated children are especially at risk. A recent analysis highlights how quickly measles can spread in communities with low vaccination coverage, a situation that could affect Thailand’s crowded markets, schools, and festivals.

Measles is one of the most infectious viruses, spreading through airborne droplets. Research shows that among those exposed who lack immunity, a large majority can become infected. For Thailand, understanding transmission in public spaces—markets, schools, and transport hubs—helps families and local authorities plan effective safeguards.

Recent studies on dietary fiber suggest psyllium husk, long valued for digestive health, may also support brain function. With only a small portion of the population meeting daily fiber recommendations, this finding could prompt readers in Thailand to rethink their routines.

Fiber is known for aiding bowel regularity and now for its role in weight management, especially amid the rise of popular weight-loss medications. The latest discussions around psyllium husk point to possible cognitive benefits alongside physical health improvements.

A recent study emphasizes how using screens before bed can undermine sleep quality. The research finds that pre-bed screen time is linked to a 59% higher risk of insomnia and about 24 minutes less total sleep. The findings stress the importance of nighttime routines that protect sleep health.

The topic resonates globally as people increasingly rely on digital devices for work and leisure. In Thailand, widespread smartphone and tablet use—especially among younger generations—mirrors these trends. The study’s message serves as a timely reminder for Thai readers to consider how late-night tech habits may affect rest.

A recent study has captured widespread attention by highlighting the significant impact of using screens before bedtime on sleep quality.

In a recent study involving 280,000 seniors from Wales, researchers have reported a significant link between receiving the shingles vaccine and a reduced risk of developing dementia. According to the study, published in the prestigious journal Nature, seniors who were vaccinated against shingles were found to be 20% less likely to develop dementia over a period of seven years compared to those who were not vaccinated. This discovery supports the emerging theory that viruses impacting the nervous system can influence dementia risk and suggests that preventive measures for dementia might already be accessible.

A large Welsh study suggests that receiving the shingles vaccine could be linked to a lower risk of developing dementia. Researchers followed 280,000 seniors over seven years and found vaccinated individuals were about 20% less likely to develop dementia than those who were not vaccinated. The study, published in a high-profile scientific journal, adds to growing ideas that infections affecting the nervous system may influence dementia risk. It also points to a preventive measure that is already available.

A simple and quick exercise known as the sit-to-stand test (STS) has emerged as a powerful indicator of aging and health, offering insights into the body’s strength, balance, and cardiovascular health. The test, which involves standing up from a seated position repeatedly in a span of 30 seconds, might seem trivial, but its implications are profound for medical assessment, particularly among the elderly.

The sit-to-stand test is widely used in primary healthcare settings to evaluate health functioning. Jugdeep Dhesi, a consultant geriatrician at Guy’s and St Thomas’ NHS Foundation Trust and professor of geriatric medicine at Kings College London, emphasizes its significance: “It tells us about their strength, their balance, and their flexibility,” she states. Research demonstrates a connection between lower scores in the test and risks of falls, cardiovascular issues, and even higher mortality.

A large study published in Epidemiology and Psychiatric Sciences shows that people who feel socially disconnected face higher risks for many illnesses. The research, led by Lisbeth Mølgaard Laustsen and colleagues, highlights three measures of social disconnection: loneliness, social isolation, and lack of social support. Together, they are linked to more health problems across multiple categories.

For Thai audiences, the findings resonate with evolving urban lifestyles in Thailand, where busier cities can reduce time with family and neighbors. The Danish National Health Survey, which involved more than 162,000 participants, measured social connections with familiar tools like the Three-Item Loneliness Scale. Results indicate that loneliness raises the risk for 11 medical conditions, with mental disorders and dementia showing particularly strong links. Interestingly, loneliness appeared to be a stronger predictor than social isolation or low social support.

A quick exercise, the sit-to-stand test (STS), is shaping how clinicians assess aging, strength, balance, and heart health. In 30 seconds, individuals repeatedly rise from a chair, revealing vital clues about overall health. What seems simple can yield profound insights for medical evaluation, especially for older adults.

In primary care, the STS test helps gauge daily functioning. A senior geriatrician explains that the test reflects strength, balance, and flexibility. Research links lower STS scores with higher risks of falls, cardiovascular issues, and even increased mortality, underscoring its value in routine checkups.

On this World Health Day, April 7, 2025, attention turns to the fundamental role of early childhood nutrition in lifelong health, harmonizing with this year’s theme “My Health, My Right.” As health disparities persist globally, this theme champions equitable access to vital healthcare services regardless of socioeconomic status. Central to this discussion is the nutritional care during a child’s initial years—a pivotal factor in shaping health outcomes far beyond early development stages.

A new study from the Swedish University of Agricultural Sciences and Chalmers University of Technology proposes a practical way to lower mercury in tuna by 25–35 percent. The approach uses cysteine, a naturally occurring amino acid, in the packaging system for canned tuna. This active packaging method works while the product sits on shelves, potentially boosting food safety without extra processing.

Mercury in fish has long raised concerns, especially for pregnant women and young children who are advised to limit high-mercury seafood. Researchers point out that cysteine has a strong affinity for binding mercury, offering a direct means to reduce mercury levels in tuna. In experiments, tuna immersed in a cysteine-containing solution transferred mercury into the liquid, lowering the fish’s mercury content significantly. Importantly, tests showed no noticeable changes in taste, aroma, or appearance even after two weeks of exposure, a key factor for consumer acceptance in Thai markets.

Researchers from a major U.S. university have unveiled an antiviral chewing gum designed to help reduce the spread of common viruses, including influenza and herpes simplex. The approach, described in a study published in Molecular Therapy, builds on earlier work showing the gum can lower viral loads in the mouth.

The gum uses ingredients from lablab beans, specifically a protein called FRIL, which can trap and neutralize viruses in the oral cavity. The study’s lead author, a professor from a dental school, says the formulation has the potential to reduce oral viral loads by a substantial margin, echoing prior results against SARS-CoV-2 detected in saliva. This points to a broader use for oral-transmitted viruses.
