Eating Chocolate During Pregnancy Has Many Benefits, Fetal Growth Is One Of Them

Good news for all you expectant mothers out there: eating 30 g of chocolate every day during pregnancy may benefit fetal growth and development.

This is the conclusion of a new study recently presented at the 2016 Pregnancy Meeting of the Society for Maternal-Fetal Medicine in Atlanta, GA.

The study results are likely to be warmly welcomed by moms-to-be, given the lengthy list of foods women are told to avoid during pregnancy.

While chocolate itself is – thankfully – absent from this no-go list, expectant mothers are recommended against overindulging in the tasty treat due to its fat, sugar and caffeine content.

There are many benefits that may come with moderate chocolate consumption, however. Chocolate contains A type of flavonoid – that have been linked to reduced risk of cardiovascular problems and lower cholesterol; the darker the chocolate, the more flavanols it contains.

Both low- and high-flavanol chocolate may have fetal benefits

The researchers enrolled 129 expectant mothers with a singleton pregnancy who were between 11-14 weeks’ gestation.

All women had double notching on the uterine artery Doppler pulsatility index at study baseline. The uterine artery Doppler pulsatility index is a test that measures uterine, placental and fetal blood flow. And notches are an indicator of the risk of preeclampsia, hypertension and other possible pregnancy outcomes.

The expectant mothers were randomized to consume 30 g of either low- or high-flavanol chocolate daily for 12 weeks. Uterine artery Doppler pulsatility was measured again at the end of the 12 weeks, and the women were followed-up until they gave birth.

However, the researchers identified a significant improvement in uterine artery Doppler pulsatility among both chocolate groups. Suggesting that both low- and high-flavonol chocolate may benefit fetal growth and development.

This improvement was much greater than what is normally expected among the general population, the team notes.

“This study indicates that chocolate could have a positive impact on placenta and fetal growth and development and that chocolate’s effects are not solely and directly due to flavanol content,” says Dr. Bujold.

Medical News Today asked Dr. Bujold whether they recommend that expectant mothers indulge in a daily dose of chocolate to improve fetal outcome. He replied:

“We cannot speculate on the overall effect of chocolate on the risk of preeclampsia from our study results. Because we did not have a group of women who were not taking chocolate.

However, previous epidemiological studies along with our results suggest that consumption of dark chocolate during pregnancy could help in the improvement of placental function.”
