Approximately two-thirds of women experience nausea or vomiting during the first trimester of pregnancy. These symptoms are commonly known as morning sickness. Hook (1976) and Profet (1988) hypothesized that morning sickness protects the embryo by causing pregnant women to physically expel and subsequently avoid foods that contain teratogenic and abortifacient chemicals, especially toxic chemicals in strong-tasting vegetables, caffeinated beverages and alcohol. We examined this hypothesis by… Expand
Nausea and vomiting of pregnancy in an evolutionary perspective.
TLDR
Evidence is found that normal levels of nausea and vomiting of pregnancy (excluding hyperemesis) protect pregnant women and their embryos from harmful substances in food, particularly pathogenic microorganisms in meat products and toxins in strong-tasting plants. Expand
Adaptive Significance of Nausea and Vomiting in Early Pregnancy
TLDR
Nausea and vomiting in early pregnancy has thought to have some adaptive merits throughout the course of evolution, though researchers are still not entirely certain of the benefits of this process. Expand
Dietary and psychosocial correlates of nausea and vomiting in pregnancy
TLDR
Evidence is found for an association between alcohol, cereals, and (especially) milk consumption on the experience of NVP symptoms, and NVP Symptoms were positively correlated with women's self-reported fatigue, stress, and depression, but negatively correlated with perceived level of support from the woman's partner. Expand
Morning Sickness: Adaptive Cause or Nonadaptive Consequence of Embryo Viability?
TLDR
A graphical model is developed and used to derive predictions from the by‐product hypothesis under two different assumptions, namely, that NVP is either a by‐products of current conflict between a pregnant woman and an embryo or a by-product of honest signals of viability produced by the embryo. Expand
Psychological Factors in Food Aversions, Nausea, and Vomiting During Pregnancy
TLDR
This review focuses on psychological and psychosocial factors as influences on NVP (“morning sickness”), including cultural, social, and associative variables. Expand
An adaptive significance of morning sickness? Trivers-Willard and Hyperemesis Gravidarum.
TLDR
It is found that HG is associated with poor maternal condition as proxied by low education, and HG affected pregnancies have a 34-percent average rate of inferred pregnancy loss, higher among less educated women. Expand
Analysis of the correlation between morning sickness and rhesus status in pregnant women in Nigeria
TLDR
It is concluded that MS is independent of Rhesus status in pregnant women, and higher incidence of [Rh-] factor in blood group O in the sample population did not establish any relationship between the intensity of MS and Rhesu negative pregnant women. Expand
Embryo quality: the missing link between pregnancy sickness and pregnancy outcome
TLDR
It is of interest that the food aversions most commonly associated with pregnancy sickness, to meat, dairy and seafoods, are also the chief dietary sources of iodine, and given that pregnancy sickness is closely linked to iodine intake and thyroid function, an obvious interpretation emerges. Expand
Morning sickness in pregnancy: mini review of possible causes with proposal for monitoring by diagnostic methods
TLDR
The hypothesis hereby proposed is that hypoglycaemia, nausea and vomiting are associated with pregnancy perhaps due to disturbances in metabolic control and increased requirements for glucose by growing foetus. Expand
Nausea and vomiting in pregnancy : prevalence and relationship with psychosocial determinants of health
TLDR
The co-morbidity of nausea and vomiting, worry, and symptoms of major depression in this sample of pregnant women represents a significant public and mental health problem and care providers need to screen pregnant women for nausea and vomit and also screen women for depression in the presence of more severe NVP symptoms.

TLDR
It is suggested that claims made in the popular press about food and health relationships should be evaluated by the media as fiction unless supported by scientific research. Expand

TLDR
It is suggested that moderate consumption of caffeine is unlikely to increase the risk of spontaneous abortion, and only extremely high serum paraxanthine concentrations are associated with spontaneous abortion. Expand

TLDR
The findings from the experimental studies carried out in mice draw attention to important principles which are of general applicability to the situation in the human, and are discussed in detail in the second part of this review. Expand
Persistent nausea and food aversions in pregnancy
TLDR
It is suggested that nausea in pregnancy may be a physiological response to foetal sensitization by dietary antigens such as cow's milk protein, due to impaired placental permeability in atopic pregnant women. Expand
Nausea and vomiting in pregnancy--a contribution to its epidemiology.
TLDR
The data obtained do not support a correlation between HCG and emesis gravidarum, but suggest an association with steroidal hormones and liver function, and a strong correlation between nausea in pregnancy and 'intolerance' of oral contraceptives. Expand
Dietary changes of pregnant women: Compulsions and modifications
TLDR
The investigators postulate that appetite compulsions may have evolved from physiological reactions to foods under the stress of pregnancy, which later became manifested in ideas or feelings now associated with specific foods. Expand
Psycho-social correlates of nausea and vomiting in pregnancy.
TLDR
Social and psychological correlates of the symptom are found and support hypotheses that suggest (a) that prolonged nausea and vomiting are associated with social difficulties during pregnancy, and (b) that first trimester vomiting is associated with attitudes suggesting an identification with a culturally held view of the female role.

TLDR
This analysis indicates that H1 blockers used mainly for morning sickness during the first trimester do not increase the teratogenic risk in humans and may, in fact, be associated with a protective effect. Expand

TLDR
It was found that gravidas who did not complain of nausea and vomiting in early pregnancy suffered abortion rates three times as high as gravidas whom no antinauseant drugs were prescribed. Expand
