Study links ten healthy diets to slower biological aging in humans
Scientists at the German Center for Neurodegenerative Diseases report on October 20, 2026, that ten distinct dietary patterns are associated with slower biological aging.
Multiple diets show similar benefits
Researchers analyzed data from approximately 7,500 participants to evaluate ten specific eating patterns. Each of these patterns, ranging from Mediterranean to plant-based options, correlated with reduced signs of aging in DNA. The analysis included the DASH diet and Nordic dietary approaches alongside others considered healthy.
No single best option exists
The investigation found that no one eating plan outperformed the rest for this specific outcome. Results confirmed through independent population data suggest various healthy choices yield comparable results. Scientists note these effects are measurable but not massive in scale.
Findings published in journal
The team released their conclusions in the scientific journal Nature Communications on this date. They emphasized that healthy eating generally aligns with slower biological aging processes. This conclusion relies on chemical changes reflecting the body's aging trajectory.
