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.

A landmark international study published this week in the Proceedings of the National Academy of Sciences (PNAS) is turning conventional wisdom about obesity on its head, revealing that a sedentary lifestyle in wealthy nations may not be the main culprit behind soaring obesity rates. Instead, the research finds that diets high in ultra-processed foods are the leading driver of the modern obesity epidemic, with important lessons for the Thai population and global public health campaigns alike (Washington Post).

A groundbreaking international study has shattered a long-held tenet of public health: that simply eating fewer calories and exercising more is the surest route to weight control. Instead, the research points to ultra-processed foods (UPFs) — industrial formulations containing five or more ingredients — as powerful, independent drivers of the global obesity epidemic, casting doubt on the decades-old mantra of ‘calories in, calories out’ as the full story behind weight gain. The findings, published this week in the Proceedings of the National Academy of Sciences (PNAS) and widely reported in reputable outlets such as the Washington Post, are sparking urgent debates among health experts and raising vital questions for Thailand’s food culture and public health strategy [Washington Post][PNAS article summary].

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 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).

Daily use of pre-workout supplements—commonplace among fitness-minded Thais and athletes—may not be as risk-free or effective as many believe, according to recent research and expert guidance. While these supplements are marketed for energy, strength, and performance, relying on them daily can cause diminishing returns, potential health risks, and a dependency that shifts the very nature of exercise motivation, new studies and international experts caution (Verywell Health).

Thailand’s booming fitness culture is mirrored in Bangkok’s bustling gyms and the popularity of national sporting events, making the latest international research highly relevant locally. Many Thais use pre-workouts as powder, drinks, or pills to enhance workouts—sometimes without fully considering the risks or regulations. As global sports nutrition finds its place in the Thai urban landscape, understanding the safety and effectiveness of supplement routines has never been more important.

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.

A new study suggests that eating just two eggs a week—roughly four ounces—may significantly lower the risk of developing Alzheimer’s disease, offering fresh hope in the battle against Thailand’s rapidly ageing population and rising rates of dementia. Researchers from prominent U.S. institutions found that individuals who consumed eggs at least once a week were 40% less likely to develop Alzheimer’s-related dementia compared to those who rarely or never included eggs in their diet. The findings, published in July 2025, center on choline, an essential nutrient abundant in eggs, which appears to play a protective role for the brain.

A groundbreaking new study tracking over 540,000 adults for nearly 30 years has ignited alarm across the global health community, revealing a significant link between diets high in ultra-processed foods (UPFs) and an increased risk of early death. Published in July 2025 and widely cited by international health experts, the research found that participants consuming the most ultra-processed foods had about a 10% higher risk of dying early, compared to those with the lowest consumption levels. With ultra-processed foods now a staple in many Thai diets, these findings carry urgent implications for national health and daily food choices.

As sunlight in Thailand blazes year-round, questions often arise about how much exposure is necessary to support healthy vitamin D levels. New research and updated guidelines released in 2024–2025 reveal that the answer is more nuanced than previously thought, with recommendations balancing the benefits of vitamin D synthesis against the risks of skin damage. Understanding this balance is crucial for Thai residents, who, despite living in a tropical climate, are not immune to vitamin D deficiency.

Dietary supplements have become an omnipresent feature of modern wellness culture, with shelves in drugstores, supermarkets, and online platforms crowded by an ever-expanding array of vitamins, minerals, probiotics, and herbal extracts. While the United States remains a major hub of the supplement industry, this rapid growth is mirrored in Thailand, where the sector has seen unprecedented expansion over the past decade. This news report investigates the forces powering the supplement surge, the health realities behind the claims, and what these trends mean for Thai consumers, health regulators, and policymakers.

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.

New research has shed fresh light on the health benefits of watermelon, moving the fruit far beyond its status as a refreshing summer snack. According to recent findings reported in the peer-reviewed journal Nutrients, watermelon consumption is associated with improved heart health and significantly better overall dietary quality, thanks to a unique combination of antioxidants, vitamins, and amino acids present in the fruit (SciTechDaily).

For Thai readers who cherish watermelon as a popular street-side treat, the significance of this research goes far beyond taste. As non-communicable diseases such as cardiovascular disease and diabetes continue to rise in Thailand, dietary strategies for prevention are critical. Watermelon, already beloved for its hydrating properties and affordability, could play a more prominent role in national health goals.

Should Thai health enthusiasts reconsider their daily fish oil supplements in favour of krill oil? The question has sparked debate as both products compete for attention in the growing wellness market. Recent research and expert opinion highlight significant similarities and key differences between these two omega-3 powerhouses, leaving many to ponder their best choice for heart, brain, and overall health Verywell Health.

For years, fish oil has been the most popular source of omega-3 fatty acids, hailed for helping to prevent and manage heart disease, high blood pressure, and inflammation. Now, krill oil—derived from tiny crustaceans found in Antarctic waters—is being marketed as a more bioavailable and antioxidant-rich alternative. With Thais increasingly concerned about diet-related illnesses and eager to adopt science-backed preventive health trends, these claims matter deeply. But does the science support making the switch?

A growing body of new research is shedding light on a potential link between vitamin D supplementation and a reduced risk of developing type 2 diabetes among individuals with high-risk prediabetes. Recent studies suggest that boosting vitamin D levels in those who are already at risk could slow or even prevent the onset of overt diabetes—a finding that may have significant implications for the millions of people in Thailand and worldwide who are living with prediabetes.

Cashews have long been beloved by snackers and chefs in Thailand alike, and recent research continues to highlight their status as a nutritional powerhouse, packed with protein and essential minerals. However, health experts are sounding a note of caution: while cashews are healthy in many ways, overindulging could come with unexpected risks, particularly due to their high calorie and oxalate content.

Cashews are a staple in many Thai households – appearing not only in popular dishes like stir-fries and salads, but also as a creamy base for dairy alternatives in the growing vegan community. With global demand for cashews soaring (the market topped $8 billion in 2022 and is projected to exceed $11 billion by 2030), understanding their nutritional profile and risks is increasingly important for Thai consumers and policymakers alike (geneseorepublic.com).
