The aim of this study was to identify sources of nutrients in diets of young Swedish vegans and omnivores. Three months of dietary intakes were investigated by diet history interviews. Volunteers were recruited through advertising and visits to schools in the city of Umeå, Sweden. Thirty vegans, 15 female and 15 male, aged 17.5±1.0 years, were compared with 30 sex-, age-, and height-matched omnivores. Vegans had different sources of nutrients than young omnivores and relied to a great extent on dietary supplements as a source of vitamin B-12, vitamin D, calcium, and selenium. Dietary intake of vegetables, fruits, and berries exceeded 500 g/day for 21 of the 30 vegans, whereas the same held true for only 1 of the 30 omnivores. Instead of animal products, young vegans rely on dietary supplements, legumes, vegetables, fruits, and berries as sources of nutrients. Copyright © 2005 by the American Dietetic Association.
