Long-Lived Genes May Give Grandkids a Healthier Start in Life

Based on: Developmental origins of exceptional health and survival: a four-generation family cohort study.

Moderate Evidence·Journal Article·Nature communications·May 2026

Grandchildren of Danish families known for exceptional longevity had about half the risk of dying in infancy compared to the general population. They also showed better health markers at birth. But by the great-grandchildren generation, this advantage faded considerably, hinting that the protective effect dilutes over time.

Key Insight

This study suggests family longevity history may offer health advantages that start in infancy, not just old age.
