Four Cups of Coffee Add Years to Life
26 Nov
Summary
- Drinking 3-4 cups of coffee daily may extend lifespan.
- Coffee impacts telomere length in severe mental disorders.
- Excessive coffee intake can shorten telomeres and lifespan.
New research indicates that moderate coffee consumption, specifically three to four cups per day, may contribute to a longer lifespan. This benefit is particularly noted in individuals with severe mental disorders (SMD), where such intake is associated with longer telomeres, akin to five additional years of biological age. Telomeres are crucial protective caps on chromosomes that influence aging.
The study, which analyzed participants with schizophrenia and affective disorders, found a J-shaped curve in telomere length relative to coffee consumption. While three to four cups showed a positive association with longer telomeres, consuming five or more cups daily was linked to adverse effects, including telomere shortening.
Experts suggest coffee's antioxidant properties may combat inflammation and oxidative stress, common factors in accelerated aging for those with SMDs. However, limitations include self-reported consumption and the need to analyze specific coffee compounds like caffeine. Further research is recommended to fully understand coffee's impact on cellular aging.
