A two-year dietary intervention significantly slows epigenetic aging as measured by the DNAmGrimAge biomarker in healthy postmenopausal women.

Adopting a diet rich in plant foods, whole grains, and vegetables while reducing meat, cakes, and saturated fats can significantly slow biological aging in postmenopausal women. You do not need extreme restrictions; consistent, moderate improvements in dietary quality over two years are sufficient to see measurable epigenetic benefits.

GoodSupportsHIGH confidence
Women who participated in the dietary intervention had a significant slowing of the DNAmGrimAge clock... The dietary intervention led to a significant reduction of delta DNAmGrimAA (β = −0.66, 95% CI −1.15 to −0.17, p = 0.01)
