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 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.

A new international review, released May 31, 2025, synthesizes cardiology perspectives to highlight eight clear signs that should prompt a visit to a heart specialist. The findings are particularly relevant for Thailand, where cardiovascular disease remains a leading cause of death and disability. Data from Thailand’s public health system show heart disease continues to impose a heavy burden, underscoring the need for earlier detection and prevention. Research from leading institutions and local guidelines emphasize that cardiovascular risk is not limited to older adults; awareness must span all ages in Thai communities.

Emerging research and expert consensus warn that many early signs of heart problems go undetected until serious health consequences arise, urging Thai readers to take seemingly mild symptoms more seriously. A new review featuring leading cardiologists, published on May 31, 2025, details the top eight signs that should prompt a visit to a heart specialist and contextualizes the relevance for Thai society, where cardiovascular disease remains one of the primary causes of death and disability (EatingWell, Statista, WHO, RCPT Guidelines).

Recent research highlights a worrying connection between low magnesium levels and an increased risk of chronic degenerative diseases. A 2024 study published in the European Journal of Nutrition points to a potential link between magnesium deficiency and conditions such as Alzheimer’s disease, diabetes, and certain cancers. Conducted by researchers in Australia, the study examined the blood samples of 172 middle-aged adults, evaluating their magnesium levels and markers of DNA damage.

A 2024 study suggests that low magnesium levels may be connected to a greater risk of chronic degenerative diseases. Conducted by researchers in Australia and published in the European Journal of Nutrition, the research analyzed blood samples from 172 middle-aged adults to examine magnesium status and DNA damage markers. The findings indicate that those with the lowest magnesium levels showed elevated homocysteine, a marker linked to higher DNA damage and potential neurodegenerative conditions such as Alzheimer’s disease and Parkinson’s disease.

A sweeping, three-decade study suggests plant-forward diets may extend the years lived free of major chronic diseases. Over 105,000 middle-aged health professionals in the United States were followed for 30 years. The findings, published in a leading medical journal, indicate that diets rich in plant-based foods and low in ultra-processed items were associated with a higher likelihood of reaching age 70 without chronic illness. Only about 9 in 100 participants achieved this milestone, highlighting the potential impact of midlife food choices.
