Does Your Coffee Choice Accelerate Your Aging? A New Study Investigates
Have you ever wondered if your morning coffee ritual could be affecting your body’s aging process? An intriguing study recently published in npj Science of Food suggests that the answer could be a resounding yes. The key factor? The way you prepare your cup of joe.
The researchers delved into the health and dietary data of 49,414 adults from the UK Biobank. The average age of the participants was 56 years. They compared the participants’ coffee habits against three primary biological aging markers, including telomere length—a cellular indicator of a person’s biological “youth”.
The findings were remarkable. Regular drinkers of filtered coffee exhibited longer telomeres and lower biological age-acceleration scores. On the other hand, those who preferred instant coffee had shorter telomeres and higher age-acceleration scores. These results were consistent even after adjusting for lifestyle factors such as smoking, BMI, alcohol consumption, and the addition of sugar or milk to the coffee.
Interestingly, the anti-aging effect seemed to intensify with the quantity of filtered coffee consumed. Participants who drank more than three cups of filtered coffee daily showed a significant reduction in biological age acceleration. Conversely, instant coffee was linked with markers of accelerated cellular aging. Metabolism and inflammation accounted for approximately 35% of this effect.
However, the researchers emphasize that this study demonstrates an association, not a direct cause-and-effect relationship. Factors such as genetics and other dietary habits could also be influential. Nevertheless, it poses a thought-provoking question for all coffee aficionados: should you opt for drip or instant?
