The association between coffee intake and risk of myocardial infarction, hypertension, breast cancer and Parkinson�s disease, to name a few, has been an object of discussion due to controversial results from various epidemiologic studies in the past. Caffeine was the main compound present in coffee that those studies were directed to. Caffeine is primarily metabolized by cytochrome P450 1A2 (CYP1A2). CYP1A2 accounts for approximately 95% of caffeine�s metabolism and shows wide variability in enzyme activity between individuals. The vast majority of the human population is fast caffeine metabolizer. It is our hypothesis that a slow caffeine metabolizer tends to consume decaffeinated coffee in order to avoid caffeine accumulation and possible adverse effects. The objectives of this presentation are to: � Evaluate the importance of the association between CYP 1A2 genotype and the frequency and type of coffee consumed (caffeinated or decaffeinated or not at all); � Validate the association between CYP 1A2 genotype and blood levels of caffeine after ingestion of a single brewed standardized cup of coffee; � Discuss the use of pharmacogenetics and pharmacogenomics to identify potential genes that can be overexpressed within the coffee drinkers and non-drinkers population.
