Morning sickness 'regulates diet'


Morning sickness might have evolved to ensure pregnant women do not digest too much unhealthy food, say scientists.
They found evidence that nausea and vomiting in pregnancy is associated with high intake of sugar, alcohol, oils and meat. In contrast, cereals were least likely to trigger sickness. The University of Liverpool analysis of 56 previous studies in 21 countries appears in the Royal Society's Biological Journal.



Morning sickness occurs in the first three months of up to 80% of pregnancies. Until recently, it was thought to be simply an unfortunate by-product of dramatic hormonal changes during early pregnancy. However, research has suggested that morning sickness might have positive consequences - such as a reduced risk of miscarriage.


The researchers believe it is possible that the pregnant human body may have evolved an aversion to foods containing high levels of toxins, and that this may have carried over into modern living. They suggest that the body might reject meat because of the relatively high risk that it might harbour disease-causing agents. Conversely, the low level of plant toxins in cereals may make them particularly unlikely to trigger nausea. However, they say the body's rejection of sugars and oils is less easy to explain.

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.

1. My wife never got morning sickness with our daughter

She miscarried twice, before our daughter was born, and was sick all the time before it happened. When she got prego with our daughter, we were on a health food kick. Never got sick, stayed fairly small, used to anger women in birth class because she could sit straight up while they all waddled.

Just sayin', might be something to it.

2. Interesting

I clicked on this because I had horrible morning sickness with both of my kids. It didn't just last a couple of weeks - it was months. I took a drug that later was taken off the market. I don't know what i would have done without it. I was sick, not just in the morning, but all day.

Oddly enough, the stuff I could keep down even with the drugs were ice creme, donuts, carbs carbs carbs.

Well the kids were born - 8lbs 14 1/2oz and 8lbs 15 oz. The drug made me feel like I was hungry all the time so I ate a lot. At least I wasn't throwing up all the time. :shrug:

Don't remember meat triggering vomiting, but the smell of coffee, alcohol, perfume, cigarette smoke sure did.

I wonder what would have happened if I were pregnant 100 years ago. Or even now when the drugs are not available.

3. testimonial

Very good friend of mine had pretty bad morning sickness. After she threw up twice in one day she went to the drugstore and bought the acupressure wristbands. (They stimulate P6, which is also the acupuncture point for helping people that get seasick). Within an hour all discomfort was gone and this lasted throughout her pregnancy. Not saying this will help everybody, but it certainly helped her. I think they were cheap. The only downside is yes, they are noticeable.
