Several investigations have brought to light the risk of caffeine consumption during pregnancy. It is linked with risk of miscarriage and preterm delivery, however a review of the American College of Obstetricians and Gynecologists has shown that consuming a cup of coffee a day during pregnancy is safe. Moderate consumption of caffeine, about 200 milligrams per day, does not contribute significantly to cause preterm births or abortions, as they have been able to conclude from studies. This measure is approximately equivalent to caffeine containing a cup of coffee from 350 milliliters. But to caffeine we not only found in coffee. It is also the equivalent to drinking four cups of tea of 240 milliliters, more than five cans of soda 350 ml a day, or eating six or seven bars of dark chocolate. The maximum dose of 200 milligrams per day is which comes recommending through several studies, some of which we have referred in the blog. We also talked about one that believes that coffee increases the risk of abortion, although it is taken in moderation. However, investigations that are in favour of moderate consumption are quite precise in terms of the quantity and agree all that exceed this recommended measure is related with an increased risk of abortion and premature birth, since caffeine crosses the placenta affecting the development of the unborn child. Even so, there are pregnant women unable to renounce their cups of coffee, even if their consumption exceeds the recommended. It is advisable at least to reduce daily consumption to a cup of coffee a day.
