While observational studies and small pilot trials suggest that vitamin D, omega-3 and exercise may slow biological aging, larger clinical trials testing these treatments individually or in combination are lacking. Here, we report the results of a post hoc analysis among 777 participants of the DO-HEALTH trial on the effect of vitamin D (2,000 IU per… Continue reading Individual and additive effects of vitamin #D, #omega-3 and #exercise on DNA methylation clocks of biological aging in older adults from the DO-HEALTH trial

Suboptimal dietary patterns are associated with accelerated biological #aging in young adulthood: A study with twins
Suboptimal diets increase morbidity and mortality risk. Epigenetic clocks are algorithms that can assess health and lifespan, even at a young age, before clinical manifestations of diseases. We investigated the association between dietary patterns and biological aging in young adult twins. MethodsThe data were drawn from the population-based FinnTwin12 study and consisted of twins aged… Continue reading Suboptimal dietary patterns are associated with accelerated biological #aging in young adulthood: A study with twins
Subcellular #NAD+ pools are interconnected and buffered by mitochondrial NAD+
The coenzyme NAD+ is consumed by signalling enzymes, including poly-ADP-ribosyltransferases (PARPs) and sirtuins. Ageing is associated with a decrease in cellular NAD+ levels, but how cells cope with persistently decreased NAD+ concentrations is unclear. Here, we show that subcellular NAD+ pools are interconnected, with mitochondria acting as a rheostat to maintain NAD+ levels upon excessive… Continue reading Subcellular #NAD+ pools are interconnected and buffered by mitochondrial NAD+
Impact of #coffee intake on human #aging: Epidemiology and cellular mechanisms
Highlights•The regular consumption of moderate doses of coffee attenuates all-cause mortality•Coffee intake attenuates age-associated diseases (cardiovascular, stroke, cancer)•Coffee and its main components (caffeine, chlorogenic acids) control stress adaptation•Coffee intake preserves the main biological mechanisms of aging AbstractThe conception of coffee consumption has undergone a profound modification, evolving from a noxious habit into a safe lifestyle… Continue reading Impact of #coffee intake on human #aging: Epidemiology and cellular mechanisms
#Physical activity and life #expectancy: a life-table analysis
Objective Low physical activity (PA) levels are associated with increased mortality. Improved measurement has resulted in stronger proven associations between PA and mortality, but this has not yet translated to improved estimates of the disease burden attributable to low PA. This study estimated how much low PA reduces life expectancy, and how much life expectancy… Continue reading #Physical activity and life #expectancy: a life-table analysis
Ultra-processed #food consumption is associated with the acceleration of biological #aging in the Moli-sani Study
BackgroundHealthy diets have been inversely associated with biological aging. However, the nutritional content is only one aspect of the overall food health potential, and more recently, increasing attention has been paid to nonnutrient food characteristics, such as food processing.ObjectivesTo examine the association of ultra-processed food (UPF) consumption with biological aging measured by circulating blood biomarkers.MethodsCross-sectional… Continue reading Ultra-processed #food consumption is associated with the acceleration of biological #aging in the Moli-sani Study
Association of Self-Reported #Sleep Characteristics With Neuroimaging Markers of Brain #Aging Years Later in Middle-Aged Adults
ObjectivesTo determine the association between early midlife sleep and advanced brain aging patterns in late midlife.MethodsUsing the CARDIA study, we analyzed sleep data at baseline and 5 years later, focusing on short sleep duration, bad sleep quality (SQ), difficulty initiating and maintaining sleep (DIS and DMS), early morning awakening (EMA), and daytime sleepiness. These were… Continue reading Association of Self-Reported #Sleep Characteristics With Neuroimaging Markers of Brain #Aging Years Later in Middle-Aged Adults
#CheekAge, a next-generation epigenetic buccal clock, is predictive of mortality in human blood
While earlier first-generation epigenetic aging clocks were trained to estimate chronological age as accurately as possible, more recent next-generation clocks incorporate DNA methylation information more pertinent to health, lifestyle, and/or outcomes. Recently, we produced a non-invasive next-generation epigenetic clock trained using Infinium MethylationEPIC data from more than 8,000 diverse adult buccal samples. While this clock… Continue reading #CheekAge, a next-generation epigenetic buccal clock, is predictive of mortality in human blood
#Metformin decelerates #aging clock in male monkeys
Highlights•Metformin prevents brain atrophy, elevating cognitive function in aged male primates.Metformin slows the pace of aging across diverse male primate tissues•Metformin counterparts neuronal aging, delivering geroprotection via Nrf2 in male primatesSummaryIn a rigorous 40-month study, we evaluated the geroprotective effects of metformin on adult male cynomolgus monkeys, addressing a gap in primate aging research. The… Continue reading #Metformin decelerates #aging clock in male monkeys
