Scientists found that morning sickness that is so popular among pregnant women is not that bad after all, as it regulates one's diet. When women carrying a child digest too much unhealthy food such as meat, oils or high levels of sugar, the body reacts and "warns" the future mother that her diet is not very
appropriate for both her and her baby.
Therefore, even if it may be seen as a paradox, nausea and vomiting are good for a pregnant woman as they work as a signal that prevents her from leading an unhealthy lifestyle.
The study also found that morning sickness has other beneficial effects, such as reducing the risk of miscarriage.
Morning sickness usually occurs in the early period of pregnancy, in the first three months. It is very popular among women, as almost 80% of them have nausea and puke in the morning. Intake of unhealthy food and alcohol were found to be the most likely to cause morning sickness, while cereals intake was found beneficial for the pregnant women.
Experts at the University of Liverpool investigated 56 previous studies on pregnancy from 21 countries and the conclusions of their research can be fully read in the Royal Society's Biological Journal.
The medical team explained that morning sickness may be due to the high level of toxins in the body of a pregnant woman. Therefore, the body's response to the intake of other toxins may result in nausea and related symptoms.
Lead researcher of the study, Dr Craig Roberts said: "While there may be no particular harm in eating, say, meat, now that we have refrigeration and best before dates, our bodies may be pre-programmed by evolution to avoid these particular foodstuffs in the first trimester. It may be that the nausea women feel towards certain foodstuffs could be helpful, and that although it is inconvenient and miserable, their nausea could be nature's way of avoiding problems in pregnancy for both mother and fetus."
