A new study shows that caffeine may be harmful to developing babies. Researchers at Yale University studied pregnant mice that were exposed to either caffeine or to a saline solution.
The researchers found the mice exposed to caffeine in the uterus had a thinner lining between the chambers of the heart. The mice getting caffeine were more likely to gain weight later in life and had reduced heart function when compared to the mice that were not exposed to caffeine.
The researchers say more studies are needed to determine the effects caffeine may have in humans. Experts add caffeine is not just in coffee and sodas it is also in certain foods, pain relievers and candy.
