Morning sickness, in a pregnant woman, could be her body's way of telling her that she is eating the wrong things, study says.
The study was carried out by researchers from the University of Liverpool, who analyzed 56 subjects from 21 countries and also studied their typical diets to understand if food could play a role in the sickness.
AdvertisementThe study suggests that morning sickness might have been nature's way of ensuring that the growing fetus is prevented from being exposed to potentially damaging foods.
It found that women who consumed plenty of sugars, sweeteners, fried food, meat, milk, eggs and stimulants such as caffeine and alcohol, increasingly suffer from morning sickness and the severity of the sickness was reduced in those mothers who fed on a predominantly cereals and pulses diet.
The lead researcher 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," he added.
