Research strongly suggests that avoidance of alcohol in pregnancy is important for the well-being of the off-spring. For example, a single drink triggered the death of 20,000 neurons per infant brains of mice. The blood alcohol levels associated with this nerve death correlate with that achieved by humans in social drinking. Thus a mother with moderate drinking habitrs might expose her unborn child to multiple occasions of irreversible brain cell death.
PositiveTip: Pregnant women should avoid all alcohol exposures for the good of their unborn.
