TROUBLE BREWING FOR MOMS- TO- BE
A new study published in the journal BMJ Open shows that even moderate caffeine consumption— for example, one to two cups of coffee per day— may be a bad idea during pregnancy.
As part of the Norwegian Mother and Child Cohort Study, researchers from Sahlgrenska Academy, in collaboration with the Norwegian Institute of Public Health, examined information from 50,943 women and found that children born to mothers who consumed caffeine during pregnancy were more likely to be overweight at preschool and school age. At age five, for instance, the share of children who were overweight or obese was five percent greater in the group whose mothers had the highest caffeine consumption, compared to those whose mothers had the lowest caffeine intake. The researchers included different sources of caffeine in the study, including coffee, black tea, and energy drinks.
