Coffee is one of the most consumed beverages in the world. The impact of coffee consumption on human health has been the subject of many clinical studies and meta-analyses. Taking into account the results of these studies, it can be concluded that coffee has a number of health benefits in terms of the population, including the reduction of the risk of death from any cause. From a clinical point of view, the safety of coffee consumption in a specific subpopulation of pregnant women is important. A large percentage of women continue to consume this drink during pregnancy, while a significant proportion of them exceed the permissible daily dose of caffeine (≤ 200 mg). During pregnancy, the metabolism of caffeine slows down significantly, which prolongs its action and penetrates into the body of the fetus. These biochemical observations have become the driving force behind numerous clinical studies assessing the impact of coffee consumption during pregnancy on its course, complications and the health of the newborn. This review article summarizes the current knowledge of these important issues.
