A recent study published in the Journal of Affective Disorders reveals that older adults who consume greater amounts of spermidine—a compound found in foods like aged cheese, mushrooms, and whole grains—tend to perform better on cognitive function tests. This finding offers a promising dietary strategy for Thailand’s rapidly aging society, where cognitive decline and dementia are growing health concerns.

The research team, led by a scientist affiliated with a U.S. university, analyzed data from over 2,600 Americans aged 60 and above, using the U.S. National Health and Nutrition Examination Survey (NHANES) conducted by the Centers for Disease Control and Prevention. Participants reported their diets through two 24-hour dietary recall interviews and completed four standardized cognitive assessments. The results showed a clear trend: those in the highest quarter for spermidine intake consistently achieved better cognitive test scores than peers with lower intake. Notably, the beneficial link was most pronounced in males, non-Hispanic whites, individuals classified as somewhat overweight (BMI 25–30), and those with hypertension or high cholesterol (PsyPost).

A major new meta-analysis led by University of Pennsylvania researchers has found that taking omega-3 supplements—commonly available in fish oil capsules—can reduce aggressive behavior by up to 28%, offering a potentially simple, affordable, and safe way to address a key public health challenge. The study, synthesizing almost three decades of international research, is the strongest evidence yet supporting nutritional intervention to reduce aggression among people of all ages and backgrounds (ScienceAlert; Penn Today).

A recent article in The Conversation brings renewed attention to the essential vitamins—from A to K—that our bodies need, revealing both their crucial roles and the everyday foods that help us meet our daily nutritional requirements (The Conversation). While “superfoods” are often marketed for their seemingly miraculous health benefits, the latest research and expert perspectives underscore that a balanced, varied diet rich in common ingredients is usually sufficient to cover most vitamin needs.

A new wave of research supported by global education experts highlights that adopting a handful of straightforward daily habits can significantly enhance a child’s academic performance. The evidence-backed practices—ranging from consistent study routines and distraction-free environments to balanced sleep and nutrition—are gaining traction among educators, parents, and health professionals alike. As Thailand prepares for another academic year, these actionable insights offer fresh direction for families eager to help children reach their full educational potential.

A new report is casting doubt on the necessity of electrolyte powders, drinks, and tablets for the average person—a market that has ballooned to an estimated $38 billion in 2024 alone. As colorful bottles and attractive marketing campaigns promise better hydration, improved health, and even performance boosts, many Thais are left wondering: do these drinks really deliver on their promises, or are they just another health fad?

Electrolyte products are marketed to athletes, fitness enthusiasts, and even ordinary people who want to enhance their daily hydration. Popular in gyms and convenience stores across Bangkok, these drinks contain key minerals such as sodium, potassium, calcium, and magnesium—elements vital for maintaining fluid balance in the body, regulating heart rhythm, and ensuring muscle and nerve function. While sports drinks have become commonplace, public health experts say many Thais may be overestimating their benefits and underestimating the power of a regular balanced diet.

Frequent childhood illness is a major concern for parents and educators alike across Thailand, with new research shedding light on everyday parenting mistakes that can undermine a child’s immunity. According to a recent report by the Times of India, many children fall ill repeatedly due to avoidable errors in care and hygiene, signalling the need for greater awareness among caregivers. These findings are particularly significant for Thai families striving to balance traditional approaches to child-rearing with modern health recommendations, as the nation continues its post-pandemic efforts to safeguard student health.

A groundbreaking global study has upended long-held beliefs about the true drivers of the obesity epidemic, finding that overeating—particularly of ultra-processed foods—is about ten times more responsible for rising obesity rates than a lack of exercise. This revelation carries profound implications for Thailand, where rates of overweight and obesity are increasing alongside rapid urbanisation and changing dietary patterns.

For decades, both Thai and international health authorities have emphasised the importance of physical activity in tackling obesity, broadcast through nationwide campaigns and initiatives. The popular narrative has been that sedentary lifestyles, especially in urban areas like Bangkok or Chiang Mai, are to blame for waistlines expanding. Yet, new research published in the Proceedings of the National Academy of Sciences (PNAS) suggests this perspective may miss the mark. Based on an analysis of over 4,000 adults from 34 nations—including hunter-gatherer tribes in Tanzania, herder-farmers in Siberia, and executives in Norway—researchers found that people across cultural and economic backgrounds actually burn roughly the same amount of calories per day, regardless of whether their lives are active or sedentary (Washington Post).

A recent feature from the Times of India has spotlighted the “Top 5 cholesterol-fighting foods”—offering fresh insights into how simple dietary changes can have substantial impacts on heart health. This latest research is especially significant for Thai readers, given Thailand’s rising rates of heart disease and high cholesterol, which authorities say are largely driven by dietary patterns and lifestyle changes associated with urbanization and economic growth.

Cholesterol has long been a central concern in public health, as elevated levels are a leading cause of heart attacks and strokes worldwide. In Thailand, noncommunicable diseases, including heart disease, account for over 70% of total deaths annually, according to the Ministry of Public Health (source). Many Thai families face these health risks due to two factors: increased consumption of fatty foods and a shift away from traditional diets rich in vegetables, fruits, and whole grains.

Across the globe, an increasing number of teenagers are turning to protein supplements as they strive to build muscle and achieve the body ideals promoted on social media. Recent research from the University of Michigan’s Mott Children’s Hospital has brought this trend into sharp focus, revealing that approximately 40% of teens consumed some form of protein supplement in the past year. This surge in popularity—echoed from the United States to Europe, and increasingly within Asian contexts—raises important questions for Thai parents, educators, and health professionals as social media-driven fitness trends reach new heights in the Kingdom.

For many Thais, cilantro (known locally as phak chee) is inseparable from everyday cuisine — sprinkled on tom yum, incorporated into larb, or simply used as a fresh garnish on soups and street-side noodles. Yet, a curious minority recoil at its presence, describing its taste as reminiscent of soap. Recent research confirms this odd aversion is grounded in genetics rather than culinary preference, reshaping our understanding of food appreciation in Thailand and globally.

A new wave of research is shedding light on the extensive—and sometimes unexpected—health implications of vitamin D deficiency, with experts warning that failing to get enough of the so-called “sunshine vitamin” could have far-reaching effects beyond what most people realize. These findings are particularly relevant for Thai readers, given shifting lifestyles, urbanization, and the rising prevalence of indoor work and study patterns, all of which can contribute to vitamin D insufficiency.

Frequent childhood illnesses are a common concern for Thai parents, especially those navigating the demands of school, day care, and modern city living. A recent article from The Times of India (“10 mistakes that cause children to fall ill frequently” timesofindia.indiatimes.com) summarizes research-backed parenting missteps that leave children vulnerable to infections. These findings, supported by international studies and echoed by health experts in Thailand, highlight crucial yet manageable steps for local families to safeguard children’s health—steps rooted in both science and everyday common sense.

A newly published article from the MIT Press Reader critically examines the long-held belief that humans must eat meat for optimal health, presenting recent research which dismantles the popular evolutionary argument justifying meat consumption. This in-depth analysis challenges the notion that our ancestors’ supposed dependence on meat has meaningful implications for modern dietary choices, with notable ramifications for public health discussions in Thailand and beyond (MIT Press Reader).

The evolutionary argument for meat eating, often used to advocate for high-protein diets like the “paleo” regimen, claims that humans evolved as obligatory meat eaters and thus must continue this pattern today. This narrative has gained traction in both Western and Thai health circles, influencing restaurant menus, consumer trends, and even government nutrition guidance. But the latest research reveals key flaws in this logic. Modern health records, large-scale dietary studies, and nutritional analyses of plant foods collectively call into question the necessity and safety of high meat intake in the 21st century.

A widely used sugar substitute, erythritol, commonly recommended for people with obesity or diabetes and found in an array of “sugar-free” products, is at the center of fresh health warnings after recent research linked it to damaging effects on brain cells and an increased risk of stroke SciTechDaily.

This finding, from a new study by researchers at the University of Colorado Boulder, raises important questions for Thai consumers who increasingly turn to artificial sweeteners in their efforts to manage weight, diabetes, and blood sugar—problems that are highly prevalent in Thailand and have changed consumption habits nationwide. As health-conscious lifestyles prompt a shift toward “no sugar” or “sugar-free” foods, the safety of these sugar alternatives is becoming a matter of significant public interest.

A recent article in The Economist has reignited debate over the effectiveness of probiotics, the so-called “good bacteria” marketed for everything from gut health to immune support. Behind attractive packaging and billion-baht marketing campaigns, probiotics promise to balance the thousands of microbial species living inside our intestines and promote overall wellness (The Economist). But does the latest research support these claims, and what does the science mean for Thai consumers who increasingly embrace probiotic supplements and drinks?

A surge in high-protein diets, popular among fitness enthusiasts and health-conscious Thais, may be unwittingly putting kidneys at risk, according to new research highlighted in a recent article by the Times of India. As protein’s reputation grows as a dietary superstar—promoting muscle gain and aiding weight management—experts warn that simple mistakes in how and what kind of protein is consumed may quietly fuel the rising tide of chronic kidney disease (CKD), especially among those already at risk.

A new clinical study suggests that the popular “5:2” intermittent fasting diet—where individuals eat normally for five days and consume very low calories on two non-consecutive days each week—could be the most flexible and effective approach for weight loss and blood glucose improvement in people with obesity and type 2 diabetes. The research, recently presented at the Endocrine Society’s ENDO 2025 conference in San Francisco, compared three well-known dietary strategies and found that all offer benefits, but the intermittent approach may provide unique advantages for those struggling to manage diabetes and weight.

A new dietary recommendation from nutrition experts is challenging the well-established “five-a-day” fruit and vegetable rule, advocating instead for a remarkably diverse plant-centric approach. Recent research and expert opinion report that regularly consuming 30 different plants per week—far surpassing the classic advice of five daily servings—may substantially improve gut health and overall wellbeing. This shift, supported by findings from major studies such as the American Gut Project, is sparking conversation in Thailand and across the globe regarding how dietary diversity can transform modern eating habits and public health.

A new wave of scholarship is challenging the common belief that America had a golden age of health—a notion recently revived by public figures such as the US Secretary of Health and Human Services, who has made headlines with the “Make America Healthy Again” campaign. This movement assumes that Americans were once notably healthier, but an in-depth look at historical records and leading expert analysis reveals a more complex—and less nostalgic—story (Bloomberg; New York Times).

A landmark study from leading U.S. researchers reveals a stark surge in ‘extremely severe’ obesity among American children over the past decade and a half, igniting alarm among health experts worldwide. Drawing on nationally representative health data, the study, published in JAMA Network Open, found the proportion of kids with the most extreme forms of obesity more than tripled between 2008 and 2023—a trend that poses urgent questions for public health both in the United States and in countries like Thailand where childhood obesity is a rising concern (Gizmodo).

The age-old debate over whether poor diet or insufficient exercise is the main culprit behind rising obesity rates has taken a new turn, with a major international study concluding that the overconsumption of calories — especially from ultra-processed foods — is far more responsible for obesity than a lack of physical activity. The research, published in the Proceedings of the National Academy of Sciences, analyzed an unprecedentedly diverse cohort and challenges assumptions long held in both public health messaging and everyday Thai life.

A groundbreaking new clinical trial has pinpointed a twice-weekly intermittent fasting regimen, commonly called the “5:2 diet,” as the most effective and sustainable strategy among three popular diets for improving blood sugar control in people with type 2 diabetes and obesity. The findings, presented at the ENDO 2025 conference in San Francisco, not only illuminate a promising approach for diabetes management but also have significant implications for Thailand, where diabetes rates are rising and dietary trends are keenly watched by both the medical community and the public.

A surge of fresh scientific evidence has upended conventional beliefs about protein intake, revealing how millions—even in Thailand—may be making critical mistakes about this essential nutrient. While protein is known as a crucial component of the Thai diet, a slew of misunderstandings, often propagated by marketing and habit, is leading to widespread shortfalls and poor choices affecting health, muscle strength, and aging across all age groups.

The latest research, gathered through interviews with dietitians and analysis of international nutrition studies, dives into six major mistakes people make regarding their daily protein, reshaping long-assumed dietary best practices. For Thai readers navigating an increasingly Western-influenced food environment, these findings signal an urgent need for re-examination, as protein requirements are not as simple—or as well met—as many believe.

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.
