This study suggests pairing a healthy diet with regular physical activity may matter more than diet alone.
In two large U.S. studies of older adults, eating a higher-quality diet was tied to slower epigenetic aging and lower death risk. About 44% of the diet-mortality link was explained by GrimAge, a biological aging clock. But when researchers accounted for physical activity, the diet effect mostly disappeared. Movement may matter as much as the menu.
