Coffee Intake for Longevity

Intake of coffee may have a profound effect in strengthening the telomere length, a biomarker of living longer, a renowned study suggested.

In a cross-sectional association between coffee consumption and telomere length in 4780 women , using the data from the Nurses' Health Study (NHS) from a prospective cohort study of female nurses began in 1976 with relative telomere length measured in peripheral blood leukocytes by the quantitative real-time polymerase chain reaction, after adjusting to other risk factors, researchers found that
1. Higher total coffee use was significantly associated with longer telomeres in compared to nondrinkers
2. Intake of 2 to <3 and ≥3 cups of coffee/d showed a relative ratio of 1.29 and 1.36, respectively
3. Telomere length was associated linearly to caffeine consumption from all dietary sources

The result of findings showed a strong indication of the correlation between coffee caffeine intake and the length of telomeres among female nurses.

Dr. Liu JJ, the led author said, " ... better understand the influence of coffee consumption on telomeres, which may uncover new knowledge of how coffee consumption affects health and longevity".

Other, in a study of total of 5826 adults from the National Health and Nutrition Examination Survey (NHANES) cross-sectionally, using the quantitative polymerase chain reaction method, telomere length compared to standard reference DNA, after adjusting to other risk factors, including age, gender, race, marital status, education, housing, smoking, BMI, physical activity, alcohol use,.. researchers showed that
1. Caffeine consumption was inversely related to telomere length
2. For each 100 mg of caffeine consumed, telomeres were 35.4 base pairs shorter
3. For each 100 mg of caffeine consumed among coffee drinkers only, telomeres were 36.7 base pairs shorter
4. Among non-coffee drinkers only, 40.0 base pairs shorter

In compared to nondrinker (40.0 base pairs shorter), coffee caffeine( 36.7 base pairs shorter) and caffeine( 35.4 base pairs shorter) intake expressed a positive effect in increased genetic telomeres length.

Taking all together, coffee (regardless caffeinated or not and numbers of cups intake per day) expressed a significant effect in increased telomeres length, the DNA implication of living longer in both genders.
