there is no disputing the importance of proper nutrition during pregnancy. there is some dispute about the safety of caffeine during this time. one concern is that caffeine may lead to miscarriages. in a study following 431 pregnant women no relationship between caffeine consumption up to 300 mg/day and adverse pregnancy outcomes was found. another study examined the relationship between caffeine consumption and spontaneous abortions in over 5 000 women and found no association. a recent study found that caffeine can reach the follicular fluid of the ovaries. it also found that an increase in coffee consumption was associated with an increased number of aborted pregnancies. on the other side research has also shown no clear relationship between caffeine intake and fertility and birth defects. even with this evidence everyone agrees that there is a limit for how much caffeine can be consumed during pregnancy. the majority of the subjects in the studies were consuming small to moderate amounts of caffeine. it is difficult to accurately test the effects of very high intakes of caffeine without risking the health of the mother and child. the american college of obstetricians and gynecologists recommends a caffeine limit of the equivalent of one to two cups of coffee per day during pregnancy.
