A ubiquitous sugar substitute found in Thai supermarkets, bakeries, bubble tea shops, and increasingly in “health” products, erythritol, has emerged as a fresh concern for heart health. Recent scientific studies—including a major investigation led by the University of Colorado Boulder—reveal that consuming even a typical serving of erythritol may rapidly trigger changes in blood vessels and platelets that set the stage for heart attack and stroke. With sugar-free and “keto” diets growing in popularity across Thailand, these findings carry weighty implications for millions of Thai consumers who have long considered erythritol as a harmless alternative to sugar.

Supplements are often viewed in Thailand as convenient boosters for health, promising better skin, stronger muscles, or a shield against illness. But new research and warnings compiled by international health authorities show that misusing these products—often unwittingly—can quietly damage vital organs such as the liver and kidneys, with consequences that may only become apparent after years of harm (Times of India). As dietary supplement use grows across Thailand—especially among urban consumers, fitness enthusiasts, and the elderly—it is essential for the public to understand the hidden risks behind the glossy marketing claims.

A new spotlight on how our meal frequency affects health has ignited debate among nutritionists and the public, following recently published research and expert commentary. The question—does eating more than three meals a day nurture or hinder our well-being?—is especially pertinent in Thailand, where traditional eating habits sometimes differ from Western norms.

Nutrition researchers and physicians have been exploring whether consuming more than three meals a day—sometimes in the form of frequent, small meals or “grazing”—delivers true health benefits or unintentionally undermines metabolic, digestive, or weight outcomes. The issue is complex, and the implications for Thai society—where bustling street food culture often promotes frequent snacking—are profound.

A groundbreaking new scientific discovery may pave the way for a “one-for-all” treatment capable of tackling some of the world’s most persistent incurable viral diseases, including HIV, Zika, herpes, and respiratory syncytial virus (RSV) (notebookcheck.net). Announced this week by an international team of researchers, the study details how a new class of compounds can supercharge the body’s natural defenses, enabling cells to resist a wide range of viruses — a potential game changer eagerly followed by the global health community and holding special promise for Thailand, where several of those diseases remain public health concerns.

A groundbreaking international study has toppled one of the most persistent beliefs about obesity: the idea that sedentary lifestyles in wealthy countries are chiefly to blame for the global epidemic of excess weight. Instead, new research published this week in the prestigious Proceedings of the National Academy of Sciences (PNAS) points squarely at what we eat—particularly the prevalence of ultra-processed foods—as the dominant cause of rising obesity rates around the world (Washington Post).

A major international study is upending deeply held beliefs about obesity, concluding that excess calorie consumption—not a lack of physical activity—is the primary cause of the obesity epidemic in the United States and other developed nations. The findings, published in the Proceedings of the National Academy of Sciences (PNAS) this week, suggest that decades of public health campaigns blaming sedentary behavior for rising obesity rates may be missing the real culprit: modern diets.

A sweeping international study published this week in the Proceedings of the National Academy of Sciences (PNAS) is challenging one of the most entrenched beliefs about obesity: that sedentary lifestyles in wealthy nations are the main culprit behind rising rates of overweight and obesity. Instead, the study points a much sharper spotlight at diet—specifically, the prevalence of ultra-processed foods—as the major driver of the global obesity crisis. As Thailand and other middle-income nations grapple with rising rates of obesity, these findings hold urgent implications for public health policies, education campaigns, and everyday choices at the dining table.

Groundbreaking research from Heinrich Heine University Düsseldorf has illuminated the double-edged effects of stress: while it binds people more closely to their in-group, it simultaneously drives hostility toward perceived outsiders. Published this week in the Proceedings of the National Academy of Sciences, the findings provide a nuanced neurobiological perspective on why group conflicts—even when costly to all—remain so persistent worldwide. This research offers valuable insights into the psychological forces underpinning social divisions, with implications for Thai society and global communities navigating rising polarization.

The oft-repeated career advice to “follow your passion” may sound uplifting, but mounting research reveals it can actually set people up for disappointment, inflexibility, and even economic hardship. As this philosophy saturates commencement speeches, motivational seminars, and social media, a growing group of psychologists and workplace researchers are urging a deeper, more practical approach to career fulfillment—especially for those in Thailand navigating education and job markets shaped by rapid technological change and economic uncertainty.

A growing body of research is shedding light on a delightful strategy for safeguarding cognitive health: keeping a pet dog or cat. As the Thai population rapidly ages and concerns about dementia and memory loss mount, recent international studies provide encouraging evidence that companionship from a furry friend could be a vital, joyful contributor to mental sharpness in later life. The latest findings, published in leading scientific journals and summarized in recent coverage by international and Thai media, point to a nuanced, species-specific association between pet ownership and the pace of cognitive decline.Kiplinger, Nature, The Guardian

A recent University of Oregon study has raised important questions about the widespread use of antihistamines among active individuals, revealing that common medications for allergies could significantly impair recovery and muscle growth following endurance exercise. Published in the Journal of Applied Physiology, the research highlights a potential trade-off for Thai readers balancing allergy management with fitness goals, as these medications may hinder the very process the body relies on to heal and adapt from exercise-induced stress (KLCC).

A new article in Psychology Today has shed light on a persistent human trait: our tendency to resist anything unfamiliar—a phenomenon that impacts Thai society and communities worldwide in subtle but powerful ways. Recent research highlights how fear of difference is nurtured not just by our brains’ wiring but by deeply embedded societal lessons learned from family, school, and cultural narratives as we grow up (Psychology Today).

The significance of these findings lies in their resonance with ongoing social, educational, and cultural challenges across Thailand. As Thai society becomes more diverse—whether through ethnic communities in the North, the southern Malay-speaking provinces, or Bangkok’s increasingly international population—the question of how we react to “the other” has real implications for social harmony, inclusiveness in education policy, and economic opportunity. By understanding why humans instinctively draw comfort from the familiar and label the different as potentially risky, we can begin to address sources of prejudice and open doors to creativity and collaboration that are essential in an interconnected world.

A growing number of parents and experts worldwide are highlighting that some “normal” parenting rules—long considered standard—may in fact cause lasting emotional damage to children, according to the latest digital debate and emerging scientific research. Recent discussions, sparked by a widely shared BuzzFeed article in July 2025, show how social media communities and mental health professionals increasingly question rules like constant teasing, forced affection, tough love, the suppression of children’s emotions, and respect for hierarchy regardless of mutual respect. Thai families, renowned for their warmth but also shaped by traditional hierarchies, may find these revelations particularly meaningful as the nation grapples with global trends in parenting and mental health.

A new wave of scientific investigations suggests that routinely taking daily vitamin supplements may not be as essential as once believed, challenging the long-standing perception that multivitamins are crucial for maintaining overall health. The discussion gained renewed attention following a recent episode of CNN’s ‘Chasing Life’ podcast, which explored the mounting evidence around vitamin supplementation and its actual impact on health outcomes for most people (cnn.com).

Thais, like people everywhere, have been long encouraged to take daily vitamins as part of a “preventive” wellness routine. In Bangkok, pharmacies and convenience stores prominently display multivitamin products, reflecting widespread cultural trust in supplements. Many parents give their children chewable vitamins, while health-conscious office workers add “multi-vits” to their daily routines, especially during the rainy season or pandemic scares. But the latest research is questioning whether this global — and intensely local — supplement habit is either necessary or effective.

A groundbreaking new study suggests a powerful interaction between low sexual activity, abdominal fat, and depressive symptoms could sharply raise the risk of early death—a finding with practical implications for health screening and preventive care worldwide, including Thailand. Published in the Journal of Affective Disorders, the study traced nearly 5,000 adults in the United States over 15 years. Researchers found that adults who reported sexual activity fewer than 12 times per year and who also had extra abdominal fat or scored high for depression faced significantly higher mortality. Most concerning, when both risk factors—wide waistlines and depressed mood—were present alongside low sexual activity, the chance of dying was almost quadrupled compared to those with neither risk factor (PsyPost).

A recent landmark study published in Nature Communications reveals that engaging in regular exercise during early life can significantly extend the period of good health, or “healthspan,” in mice, even though it does not increase overall lifespan. This finding offers new insight into how early-life behaviors can influence long-term health outcomes, with implications that could ultimately inform human public health strategies—including those in Thailand, where prevention of age-related diseases is gaining national attention (Nature Communications).

Neuroscientists have uncovered fresh insights into the brain’s remarkable ability to juggle several pieces of information at once, revealing that our minds selectively devote more resources to items deemed important. The latest research, published in Science Advances on July 8, 2025, demonstrates that two major brain regions—the visual cortex and the frontal cortex—coordinate to ensure sharper memory for high-priority contents, while de-emphasizing those considered less critical. This discovery opens intriguing avenues in understanding not only basic neuroscience but also practical strategies to boost personal and educational performance for Thais in an increasingly information-rich world (PsyPost).

A recent study from the University of Georgia has challenged the long-held belief that more exercise automatically translates to better mental health, revealing that not just the act of exercising, but the context in which it occurs, plays a pivotal role in determining its psychological impact (UGA News). This latest research invites Thai readers to rethink the way society prescribes and participates in physical activity, suggesting important implications for health promotion, education, and community wellness.

A newly published review in JAMA Psychiatry has sparked controversy among mental health experts, raising concerns that it significantly underestimates the risks faced by long-term users of antidepressants when they attempt to discontinue their medication. The debate centers on the review’s focus on short-term, industry-funded studies and has important implications for millions worldwide, including a growing cohort of patients in Thailand who rely on antidepressant therapy.

Antidepressant withdrawal — the range of physical and psychological symptoms experienced when stopping or reducing dosage — has come under increased scrutiny as more people use these medications for extended periods. While previous medical guidelines, such as those from the UK’s National Institute for Health and Care Excellence (NICE), described withdrawal as “brief and mild,” recent scrutiny has revealed a more complex picture, particularly for long-term users. The new JAMA Psychiatry review, authored in part by academics with ties to pharmaceutical companies, concludes that withdrawal symptoms from antidepressants are generally not clinically significant for most users, especially those on the medication for only eight to twelve weeks. Its analysis, based on eleven trials — the vast majority of which involved short-term use — found slightly more withdrawal symptoms in those stopping antidepressants than in placebo groups, but the authors attribute much of this to the “nocebo effect” (the power of negative expectations to trigger adverse symptoms) rather than to withdrawal itself.

A recent study published in The Journal of Social Psychology has revealed a provocative link between national narcissism and emotional impairments, echoing global worries about rising divisiveness and prejudice. Individuals exhibiting high national narcissism—an extreme form of national pride characterized by a hunger for recognition and hypersensitivity to criticism—show diminished ability to understand both their own and others’ emotions. The research also connects these emotional deficits to increased tendencies toward dehumanization, affecting perceptions of both outsiders and fellow citizens within their own nation (PsyPost).

In a fascinating turn for relationship sciences, new research has shed light on the specific facial features women notice first when evaluating a man’s attractiveness. Contrary to the prevailing idea that broad general impressions or stereotypically “obvious” features dominate initial attraction, evidence now points overwhelmingly to three key facial characteristics: the lips, jawline, and cheekbones. This revelation comes from a 2009 study published in the Journal of Experimental Social Psychology and has been widely discussed in contemporary media, including recent analysis by YourTango and ScienceDaily (YourTango; ScienceDaily).

A new psychological study suggests that the way children are parented—especially when that parenting is cold, abusive, or overly controlling—can have lasting effects on their adult lives, with certain personality traits serving as the connecting thread. Published in Psychological Reports, the research sheds light on why negative parenting is tied to later emotional, social, and occupational difficulties, and points to the key role of personality traits such as conscientiousness in explaining this link (PsyPost).

In a recent analysis published by Forbes, a psychologist has shed new light on the two dramatic extremes in the spectrum of romantic relationships—intensely obsessive love, known as love mania, and a debilitating fear of love itself, described as philophobia. These findings are shaping contemporary understanding of how individuals relate to intimacy, with wide-ranging implications for mental health professionals and everyday people alike (Forbes.com).

For Thai readers, where cultural ideals often emphasise harmonious relationships and filial piety, this research is a timely reminder that the psychological underpinnings of love can be as complex as they are universal. In a society that values family cohesion and long-term commitment, understanding the extremes of emotional attachment—and detachment—may offer important insights for navigating everything from romantic partnerships to friendship and kinship.

A growing body of scientific evidence shows that exercise alone may do far less for weight loss than once believed. Recent studies, as discussed in Psychology Today, confirm that while physical activity confers significant health benefits, its direct effect on body mass index (BMI) is minimal—especially compared to dietary changes. For many Thais striving to lose weight, this revelation upends traditional advice and encourages a fresh, evidence-based approach to managing obesity and related health concerns.
