Abstract
Dietary
strategies to enhance the content and bioavailability of iron and zinc
in vegetarian diets were compiled. Strategies included increasing
promoters and decreasing antagonists of iron and zinc absorption,
adopting food preparation and processing methods which hydrolyze the
phytate content of cereals and legumes, and using iron cookware. These
strategies were used to devise two vegetarian menus based on food
consumption patterns derived from three day weighed food records of 78
Canadian lacto-ovo-vegetarian adolescents. The iron and zinc, as well
as calcium, phosphorus, thiamin, riboflavin, niacin, vitamin A, protein
and energy content of the devised menus were all higher than the actual
intakes and the corresponding Canadian recommended nutrient intakes.
Results show the overall nutrient adequacy of the recommended
vegetarian menus and indicate that young lacto-vegetarian women can
potentially meet their estimated dietary requirements for absorbed iron
and zinc through modest modifications to the diet. Laboratory studies
designed to measure the total amount of iron and zinc absorbed from
these diets by young vegetarian women are needed to verify the efficacy
of the devised menus.
