News MedicalFiltered Coffee Links to Slower Biological Aging While Instant Coffee Shows the Opposite

ℹ️ Observational Association Only Evidence

Researchers analyzed 49,414 UK Biobank participants and found differing associations between coffee preparation methods and biological aging measures. Filtered coffee was associated with lower biological age acceleration, while instant coffee was associated with higher age-acceleration scores.

Clinical Considerations

• Filtered coffee was associated with lower PhenoAge and KDM biological age-acceleration measures.
• Instant coffee was associated with higher age-acceleration scores and shorter leukocyte telomere length.
• Most observed instant-coffee effects corresponded to approximately 0.1-0.2 years of age acceleration.
• Cross-sectional design and self-reported consumption limit interpretation and did not establish causality.

Practice Applications

• Interpret findings as observational associations rather than dietary guidance.
• Recognize coffee preparation method as a potentially relevant exposure variable.
• Consider residual confounding when discussing lifestyle-related aging studies.
• Monitor future prospective and intervention data for validation.
