“These findings suggest that psychosocial stress accelerates immune aging, potentially driving disease and premature death in vulnerable groups. However, lifestyle practices may moderate this risk.”

“Low vitamin D levels promote brain aging and loss of brain volume and gray matter. A recent study found that the brains of people with low vitamin D levels age faster. Having high vitamin D levels may protect the brain, however.”

“Monocytes use a lot of nicotinamide adenine dinucleotide (NAD+), which is an important energy source for cells. The authors suggested this decrease in monocytes and subsequent increase in NAD+ may be responsible for the reversal of epigenetic aging.”

“To test psilocybin's potential effects on aging, researchers treated human lung and skin cells with psilocin in the lab. They tracked how long the cells kept dividing before entering senescence—a state where cells stop dividing and begin to deteriorate.”

“The data revealed only a weak association between higher diet quality and epigenetic age as measured by the two aging clocks designed as predictors of chronological age (Horvath and Hannum clocks).”

“Given the wide range of diseases associated with gastrointestinal microbiota composition, its effects on aging are an area of intense interest. Prior investigations have demonstrated that transfer of the fecal microbiota from aged mice to young mice alters immunity, neurogenesis, and cognition; however, the consequence of fecal transplantation from young mice to aged mice is unknown.”

“Magnesium may protect the brain from age-related volume losses, a new study showed. People with the highest magnesium intake had larger brain volumes than those with lower intake – a protective effect that corresponded to roughly one year less aging.”

“Living in multilingual environments was linked to roughly half the odds of accelerated aging. Longitudinal results showed the same trend. Monolingual environments raised the risk of faster aging by 43%, while multilingual environments lowered it by about 30%.”

“Having a higher epigenetic age was also associated with a 6% increased risk of getting cancer within 3 years. Epigenetic age is a new way to measure your biological age and is based on a blood test that identifies methylation patterns in DNA.”

“However, findings from a new study suggest that some survivors of childhood cancer are genetically susceptible to experiencing accelerated epigenetic aging. Epigenetic age acceleration is a phenomenon that occurs when a person's epigenetic age exceeds their chronological age.”
