Dietary status of Seventh-day Adventists and nonvegetarians.
The dietary intakes of Seventh-day Adventist (SDA) vegetarians and nonvegetarians, as well as of non-SDA nonvegetarians, were generally adequate. However, even though iron and vitamin B6 intakes exceeded 100% and 90% of the RDAs for all men, 26% and 19% of the women were consuming less than 60% of the RDAs for iron and vitamin B6.
