Ce dossier présente deux études évaluant l'association entre la consommation de café et le risque de décès par cancer ou autres maladies : l'une menée dans 10 pays européens auprès de 521 330 participants de la cohorte EPIC (durée moyenne de suivi : 16,4 ans), l'autre menée aux Etats-Unis à partir de questionnaires auprès d'une cohorte multi-ethnique incluant 185 855 participants (âge : 45 à 75 ans ; durée de suivi : 3 195 484 personnes-années)
Coffee is one of the most frequently consumed beverages worldwide. In the United States, about 75% of adults drink coffee, and 50% drink it daily (1). Coffee is a major source of caffeine, with wide variation in the amount among different types of coffee (8 mg of caffeine per fluid ounce of instant coffee, 12 mg per fluid ounce of brewed or drip coffee, and 64 mg per fluid ounce of espresso). In addition, coffee contains several bioactive substances, including polyphenols, diterpenes, and melanoidins, also with wide variability depending on the blend and the roasting and brewing methods. Adding sugar, cream, or cream substitutes adds calories. Because of the widespread consumption of coffee, understanding its health effects is important.
