Association of Coffee Consumption with Serum Activities of Liver Enzymes in Normal Saudi Male Population

Objective To examine the association of coffee consumption with serum activities of liver enzymes in Saudi men living in Western region of Saudi Arabia (Makkah) in order to consider the interactive association with major demographic factors. Materials and Methods In this free-living population study blood samples were collected from 200 male subjects ages ranged between 18 and 65 years, with a mean age of 41.4 12.69 years, fasting for 10-12 hours before sample collection. Liver function tests were investigated. Results Heavy coffee drinking was significantly associated with lower levels of serum total cholesterol, total protein, albumin, and AST, but did not affect ALT, and TB. GGT level was not independently associated with coffee consumption. Conclusion The results of the present study demonstrated that heavy daily coffee drinking significantly affects serum cholesterol and protein levels. However, the correlations between coffee consumption habits and these levels require further investigation through epidemiological studies with a larger sample size, including different age groups and populations.
