New Study Identifies Effective Interventions for Slowing Biological Aging
A recent study led by Raghav Sehgal, an associate research scientist in psychiatry at Yale University, has identified specific interventions that can measurably slow the biological aging process. Published in Nature Medicine, the research analyzed data from 51 anti-aging intervention studies, examining a range of strategies from supplements to medical procedures. The team utilized a new class of DNA-based blood tests, specifically epigenetic clocks, which measure patterns of methyl groups on DNA to estimate biological age. The findings indicate that lifestyle interventions, such as a combination of healthy diet and exercise, consistently decreased epigenetic age. Pharmacological interventions, including metformin, semaglutide, and anti-TNF therapies, showed the most significant decrease in epigenetic age. Conversely, over-the-counter supplements and certain medical procedures did not demonstrate a reduction in epigenetic age.
