Filtered Coffee Linked to Slower Ageing Than Instant
A new study looked at how different types of coffee affect how our bodies age.
Researchers found that people who drink filtered coffee might age more slowly biologically, while those who drink instant coffee might age faster.
This is because filtered coffee has more good stuff like antioxidants that can help keep us healthy.
But the study can't say for sure that filtered coffee makes you age slower, just that there's a link.
Experts say we should keep eating healthy and exercising, and not rely on just one thing like coffee to stay young and healthy.
Filtered coffee is associated with slower biological ageing, while instant coffee is linked to faster ageing.
The study used three biological ageing markers: rLTL, PhenoAgeAccel, and KDM-BAAccel.
Filtered coffee contains beneficial bioactive compounds like chlorogenic acids and antioxidants.
The study was observational and cross-sectional, meaning it can't prove causation.
Experts recommend a healthy lifestyle over relying on a single food or beverage for healthy ageing.
- Who

- When
- The study was published in npj Science of Food, with data collected from UK Biobank participants.
- Where
- The study was conducted using data from the UK Biobank.
- Why
- To investigate how different coffee brewing methods might influence biological ageing and overall health.
Filtered Coffee Benefits
Instant Coffee Concerns
Biological Ageing Markers
Filtered Coffee Benefits
Filtered coffee is associated with lower biological age acceleration scores and longer telomeres, suggesting healthier ageing.
Instant Coffee Concerns
Instant coffee is linked to higher biological age acceleration scores and shorter telomeres, indicating faster biological ageing.
Bioactive Compounds
Filtered Coffee Benefits
Filtered coffee contains beneficial compounds like chlorogenic acids, polyphenols, caffeine, and antioxidants that may reduce inflammation and improve metabolic health.
Instant Coffee Concerns
Instant coffee may lack the beneficial compounds found in filtered coffee, potentially offering fewer health benefits.
