A new study shows that having too much caffeine during pregnancy may impair a baby's liver development and increase the risk of liver disease in adulthood.
This study was published in the Journal of Endocrinology.
Pregnant rats given caffeine had offspring with lower birth weights, altered growth and stress hormone levels and impaired liver development.
The findings indicate that consumption of caffeine equivalent to 2-3 cups of coffee may alter stress and growth hormone levels in a manner that can impair growth and development, and increase the risk of liver disease in adulthood.
Previous research showed that prenatal caffeine intake of 300 mg/day or more in women, which is approximately 2 to 3 cups coffee per day, can result in lower birth weights of their children.
