- 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.
