Abstract These studies examined the relationship between salt preference of adult offspring and their mothers' symptoms of morning sickness during pregnancy. College students who could provide information about their mothers' symptoms of morning sickness completed a survey about their dietary salt intake (study 1; n = 169) or rated and consumed ten snack foods (study 2; n = 66). In study 1 a salt-use score was calculated based on responses to the Salt Intake Questionnaire; offspring of women with moderate or severe vomiting reported a significantly higher level of salt use (p < 0.01) than those whose mothers report little or no symptoms. In study 2 saltiness and pleasantness ratings of high-salt foods, intake of those foods and total sodium intake were the focus of analysis. Offspring of women reporting moderate or severe vomiting showed a significantly greater preference for the snack food subjects rated as saltiest than those whose mothers reported no or mild vomiting. They also ate more of that food and consumed more total sodium during the test session. Effects were stronger in Caucasian than Asian subjects. These studies suggest that moderate to severe vomiting during pregnancy can be associated with significantly higher salt intake in offspring. Thus, a gestational event may be an important determinant of salt intake and preference in adulthood.
