Most physicians in the world with full responsibility declare avid coffee lovers - the relationship between this aromatic drink and pregnancy is confrontational. In 2008, a study was conducted by a group of Italian doctors, which showed that consumption of 200 mg or more of caffeine by a woman during pregnancy doubles the risk of miscarriage compared to pregnant women who do not.
The scientific literature is full of studies of the effects of caffeine on the fetus, and often gives conflicting recommendations.
