Abstract

Relationships between dietary nutrients and plasma and fecal estrone, estradiol-17β, testosterone, and plasma prolactin levels were studied in young Seventh-day Adventist men: 18 nonvegetarians (NV), 20 lacto-ovovegetarians (LOV), and 15 vegans (V). Blood samples and 3 d dietary records were obtained. Contemporaneously collected diet composites and stool samples were analyzed for fiber. The vegetarians consumed significantly more fiber than the omnivores, while NVs and LOVs consumed more saturated fat than the Vs. Although plasma steroid hormone status did not differ, the Vs had significantly higher fecal estrogen levels than the NVs or LOVs. Plasma prolactin levels were significantly higher in the NVs and LOVs than in the Vs. Significant relationships were observed for the combined groups between dietary and fecal fiber components and fecal, but not plasma steroid hormones. For the combined groups, prolactin levels were positively correlated with saturated fat intake. Further research is warranted to study the effects of dietary nutrients on endocrine homeostasis in other age groups.
