Objectives: Significant inverse association between coffee intake and the levels of liver enzymes has been reported. We demonstrated higher prevalence of metabolic syndrome in Korean immigrants (KIs) than in indigenous Japanese (IJs). The aim of this study was to investigate whether the association between coffee intake and liver enzyme levels was different between the 2 ethnic groups.
Methods: This study is a cross-sectional study including a total of 966 subjects comprising KIs and IJs. The association between the quintiles of coffee intake and dichotomous values of liver enzymes was evaluated by logistic regression analysis in KIs, IJs, a high-risk group (current smokers or alcohol drinkers ≥45 g/day), and a low-risk group (non-smokers and alcohol drinkers <45 g/day).
Results: In KIs, a significant inverse association between coffee intake and serum aspartate aminotransferase (AST) levels was observed. In the IJs, a significant inverse association between coffee intake and serum alanine aminotransferase levels was observed. In the high-risk group, a significant inverse association between coffee intake and serum AST and gamma-glutamyltransferase levels was observed.
Conclusion: No difference was observed between KIs and IJs regarding the association between coffee and liver enzymes. Coffee might inhibit hepatic damage by alcohol drinking and smoking.

Coffee has long been popular worldwide. The rise in lifestyle-related diseases such as cardiovascular disease, diabetes, stroke, dementia, and others has motivated coffee usage and illness prevalence studies. Some studies show coffee consumers are at risk for such diseases, whereas others show its active components protect them.

Background: Caffeine, identified as a central nervous system stimulant in foods, beverages (coffee, tea, chocolate), and medications, has been focused on its ergogenic properties, enhancing physical performance. The aim of this study was to investigate the association between the caffeine intake (from coffee) and fat-free mass index (FFMI).
Materials And Methods: We carried out a cohort study that included 3,466 women and 3,145 men aged ≥20 years who were intaking caffeine.

Parkinson's disease (PD) is a common progressive neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc). Environmental and lifestyle factors, such as smoking and coffee drinking, have been associated with a decreased risk for PD. However, the biological mechanisms underlying protective effects on PD are still not fully understood.
