The DO-HEALTH study, a robust randomized clinical trial, meticulously tracked 777 participants aged between 70 to 85. Through a combination of daily supplementation and health-focused lifestyle changes, the study offered a groundbreaking look into factors promoting longevity. Participants were divided into groups, with some receiving a daily 1-gram omega-3 supplement, others a vitamin D supplement, and some engaging in a consistent exercise regimen. The aim was to determine which combinations were most effective in slowing biological aging.

A six-year study from a leading Canadian university indicates that older women who engage in a broad spectrum of social activities tend to consume more fruits and vegetables. The findings suggest social connectedness can influence healthy eating patterns, offering practical lessons for Thai communities seeking to improve nutrition among older adults.

In Thailand, where communal ties and family networks are central, social participation may reinforce healthy routines. Thai researchers and health professionals note that community clubs, religious gatherings, and intergenerational activities can provide structures that encourage regular meals, healthier food choices, and greater awareness of nutrition. Data from institutions evaluating aging and public health shows that social engagement correlates with improved dietary quality, particularly among women who balance caregiving, work, and social duties.

New research from a leading aging and nutrition center at Tufts University reveals that vitamin K supports brain health, especially as people grow older. Known for its role in blood clotting, vitamin K appears to help maintain brain function. The findings stress eating green, leafy vegetables such as spinach, kale, and broccoli, which are rich in vitamin K.

Researchers studied the hippocampus, a brain region essential for memory and learning, using middle-aged rodents fed a diet low in vitamin K. They focused on menaquinone-4, a common vitamin K form in the brain, and observed notable changes in behavior and brain structure when this nutrient was scarce.

In a groundbreaking study, researchers from the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University have uncovered that vitamin K, commonly associated with blood clotting, plays a crucial role in maintaining brain health, especially as we age. This discovery highlights the importance of a diet rich in green, leafy vegetables such as spinach, kale, and broccoli, which are abundant sources of vitamin K.

The study focused on the hippocampus, a brain region essential for learning and memory, and utilized middle-aged rodents to determine how a diet deficient in vitamin K affects cognitive function over six months. The researchers centered their analysis on menaquinone-4, a prevalent form of vitamin K in the brain. Significant alterations in both behavior and brain structure were observed in mice lacking this nutrient.

As we advance in years, maintaining mobility often becomes a challenge. However, the latest research by Dr. Kelly Starrett, a physical therapist with a background in athletics, suggests that it need not be an inevitability of aging. His insights, recently discussed on CNN, highlight practical strategies that older adults can employ to retain and even enhance their flexibility and independence.

Starrett emphasizes the misconception that reduced range of motion is an unavoidable consequence of aging. Instead, he proposes that efforts should focus on maintaining and regaining one’s natural range of motion. The couple’s recent book, “Built To Move: The 10 Essential Habits To Help You Move Freely and Live Fully,” coauthored with Juliet Starrett, outlines simple yet effective practices that can be integrated into daily routines without overwhelming time commitments.

A recent study published in Nutrition investigates whether a very low-calorie ketogenic diet can influence biological aging. Conducted in Spain, the research suggests that this dietary approach may slow aging at the molecular level by more than six years.

The study focuses on epigenetic aging—the difference between a person’s biological age and calendar age. Epigenetic aging is important because a higher biological age is linked to greater health risks and shorter lifespan. In this trial, obese adults followed a low-calorie ketogenic diet for 180 days. Researchers observed a substantial reduction in biological age, exceeding six years.

A groundbreaking study published in Nature has developed the largest and most detailed single-cell map of how the brain ages, revealing which cell types and regions are most susceptible to changes over time. Conducted by researchers at the Allen Institute for Brain Science, the study mapped over 1.2 million brain cells from both young and older mice, uncovering key vulnerabilities in the hypothalamus—a region crucial for regulating hunger, hormones, and energy balance source.

A new single-cell brain map in Nature reveals which cell types and regions are most affected by aging, offering guidance for Thailand’s aging population. Researchers at the Allen Institute for Brain Science analyzed over 1.2 million brain cells from young and older mice, spotlighting a vulnerability hotspot in the hypothalamus. The hypothalamus regulates hunger, hormones, and energy balance, suggesting links between aging, metabolism, and cognitive changes.

Data from leading neuroscience centers show aging affects the brain unevenly. Rather than a uniform decline, specific cell types undergo distinct gene-expression changes over time. Using single-cell transcriptomics, investigators compared gene activity across life stages akin to human young adulthood and middle age. The study identified 2,449 genes with age-related changes, concentrated mainly in the hypothalamus, pointing to a potential target for interventions aimed at healthy aging and neurodegenerative disease prevention.

A major study from Harvard T.H. Chan School of Public Health, with collaborators in Copenhagen and Montreal, confirms a clear message: mid-life eating habits influence how we age.

A growing body of science suggests that a very low-calorie ketogenic diet (VLCKD) may influence aging markers and could slow biological aging by years, particularly for people with obesity. While findings are early, they are drawing interest from scientists and health professionals in Thailand and around the world.

Recent research indicates VLCKD can drive meaningful weight loss while also affecting molecular markers associated with aging. Experts say ketosis may influence cellular processes that underlie aging, possibly through improved insulin regulation and metabolic health. For aging researchers, these results offer a new lens on how dietary patterns might shape long-term health outcomes.

A long-term study from Harvard T.H. Chan School of Public Health links specific dietary patterns to holistic healthy aging. Published in Nature Medicine, the research followed more than 100,000 people over 14 years, showing that balanced diets support longevity and overall well-being beyond physical health, including cognition and mental health. The findings carry particular relevance for Thailand as it faces a rapidly aging society.

The study analyzed middle-aged participants with various self-reported diets, including reduced processed foods and a balance of animal and plant-based nutrition. Those consuming plenty of fruits, vegetables, whole grains, and unsaturated fats from nuts and legumes tended to experience better health outcomes after age 70. Co-author Marta Guasch-Ferre, adjunct associate professor at Harvard, notes that healthy aging involves meeting cognitive, physical, and mental benchmarks while remaining free of chronic disease.

The ketogenic diet, while often controversial due to its high-fat content and strict carbohydrate restrictions, may offer unexpected benefits for reversing biological aging, according to recent studies. A small yet promising study suggests that adhering to a very low-calorie ketogenic diet (VLCKD) can potentially reverse epigenetic aging by over six years, particularly in individuals with obesity. This revelation adds a surprising dimension to the ongoing discourse on nutrition and aging, igniting both scientific and public interest in Thailand and globally.

A new study from researchers at a major U.S. medical school demonstrates that strengthening the brain’s waste-clearing system can improve memory in aging mice. The approach targets the meningeal lymphatic vessels surrounding the brain, which drain waste to the body’s lymph nodes. By enhancing this clearance, older mice showed clearer memory and curiosity toward new objects, suggesting a potential pathway for human therapies against age-related cognitive decline and neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

A Spanish study investigates whether a very low-calorie ketogenic diet can slow aging at the molecular level, focusing on individuals with obesity. Published in Nutrients, the study suggests that about six months on this diet may influence markers of biological age. Researchers tracked DNA methylation and other epigenetic changes, finding that overweight participants starting with signs of accelerated aging showed improvements indicative of a younger biological age after 180 days on the regimen.

Recent research has unveiled promising insights into the role of dietary habits in midlife as a determinant of chronic disease prevention in later years. Conducted by prestigious institutions including the T.H. Chan School of Public Health, University of Copenhagen, and University of Montreal, the study tracked 105,000 individuals aged between 39 and 69 over a span of up to 30 years. Findings suggest that a diet rich in plant-based foods, complemented by a moderate intake of meat, significantly reduces the risk of chronic illnesses.

A promising new study conducted by researchers at Washington University School of Medicine in St. Louis reveals a groundbreaking technique that significantly improves memory in aging mice. By enhancing the brain’s waste removal system, specifically through stimulating the meningeal lymphatics, researchers have made strides that could eventually inform treatments for age-related cognitive decline and neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases.

As detailed in Cell source, the study shows that by boosting this natural brain-cleansing process, memory in older mice improved remarkably. The meningeal lymphatics form a physical system around the brain responsible for channeling waste products away and into the body’s lymph nodes. It traditionally helps regulate brain waste but slows down with age, leading to potential cognitive impairments.
