Scientists have discovered that coffee's anti-aging effects may be driven by plant compounds, not caffeine. A new study from Texas A&M University shows these compounds bind to a receptor called NR4A1, which helps regulate stress, inflammation, and tissue repair.
NR4A1 expression declines with age, increasing disease susceptibility. In cell experiments, coffee compounds activated this receptor, inhibiting cancer cell growth and reducing inflammation. Caffeine itself had little effect.
While the study highlights the role of compounds like chlorogenic and caffeic acid, coffee contains over 1,000 chemicals. More research is needed to confirm how these findings apply to human health.
