There might be a reason for all that morning sickness in pregnancy. Researchers say nature devised it to make sure that the would-be mother will not digest unhealthy foods.
High intake of sugar, alcohol, oils and meat were found to be associated with the vomiting in pregnancy, the researchers said. Researchers at the University of Liverpool analyzed 56 previous studies in 21 countries to arrive at these conclusions.
They report their findings in the Royal Society's Biological Journal. Until recently, morning sickness was viewed as an unfortunate event that every pregnant woman goes through, but recent findings say that its appearance could avert miscarriages.
