How to live longer: coffee consumption could prolong survival – study
Functional and structural changes that accumulate over time are mostly unavoidable. But scientists remain committed to identifying feasible ways to slow this process, and their research continues to bear fruit. The latest scientific research offers an indication of how coffee consumption may impact lifespan.
A new study of more than 170,000 people in the UK suggests that those who drank between two and four cups of coffee a day had a lower risk of death from all causes.
The study, conducted by the School of Public Health at Guangdong Southern Medical University, found no difference in risk of death between coffee drinkers who added sugar and those who did not.
After adjusting for several confounding factors, the researchers found that regular coffee drinkers were significantly less likely to die from any cause, heart disease or cancer, compared to non-drinkers.
Benefits were consistent across multiple types of coffee types, including ground, instant, and decaffeinated.

Estefaniá Toledo, MD, PhD, of the Department of Preventive Medicine and Public Health at the University of Navarre in Spain, however, advised caution when adding sugar to coffee drinks.
The findings are consistent with previous studies that have suggested coffee may reduce the risk of several neurodegenerative diseases and liver problems.
Coffee has already been shown to influence gene activity via epigenetic changes.
It includes several chemical compounds recognized for their potential therapeutic effects.
A key component is chlorogenic acid – an antioxidant abundant in fruits and vegetables that protects against oxidative stress – a key factor in chronic disease.
Researchers suggest the compound may also boost mood, help heal infections and lower blood sugar levels.
It exerts its benefits by inhibiting the enzyme alpha-glucosidase, responsible for breaking down carbohydrates and limiting the absorption of glucose during digestion.
However, other components of coffee can pose health risks.
