title: Nutritional Status of Water-soluble Vitamins Did not Differ According to Intake Levels of Wheat and Wheat Alternatives and Rice and Rice Alternatives as a Staple Food in Pregnant Japanese Women.
abstract: The objective of this study was to investigate whether the intake level of a staple food influences the nutritional status of water-soluble vitamins in pregnant Japanese women. Urinary excretion of water-soluble vitamins was used as a biomarker for nutritional assessment. Twenty-four-hour urine samples were collected and vitamin intake was surveyed using a validated self-administered comprehensive diet history questionnaire. Subjects were categorized into bottom, middle, and upper tertiles according to the percentage of total energy intake from wheat and wheat alternatives or rice and rice alternatives. The present study showed that the nutritional status of water-soluble vitamins did not differ with intake level of wheat and wheat alternatives or rice and rice alternatives as a staple food in pregnant Japanese women.
