Overview

• Research presented at the Nutrition2025 conference showed that each additional cup of caffeinated coffee up to five per day was associated with a 2–5% greater likelihood of meeting healthy aging criteria by age 70 among 47,513 nurses.
• A separate analysis of CDC NHANES and mortality records published in the Journal of Nutrition found that consuming one to three cups of coffee daily corresponded to a 15% lower risk of death over the next 9–11 years when minimal sugar or saturated fat was added.
• No link to healthy aging emerged for decaffeinated coffee or tea, while each daily cup of caffeinated soda was tied to a 20–26% decrease in the odds of aging without major chronic diseases.
• Scientists point to coffee’s unique mix of bioactive compounds beyond caffeine as possible factors in its protective effect and are pursuing further research to isolate and understand these components.
• Researchers emphasize that coffee’s benefits remain modest compared to overall lifestyle habits but indicate that moderate intake could complement healthy behaviors such as regular exercise and a balanced diet.
