Groundbreaking research elucidates the epigenetic mechanism that may be responsible for why eating fewer calories increases longevity.
As early as 1935, scientists showed that limiting the intake of calories can drastically increase the lifespan of mammals.
New research brings us closer to understanding why that may be. Researchers from the Lewis Katz School of Medicine (LKSOM) at Temple University in Philadelphia, PA, have uncovered a mechanism that might explain why calorie restriction has such a beneficial effect on longevity.
The mechanism has to do with epigenetics and bears the name of “methylation drift.”
