Summary

Background
Iron deficiency is common in young women and associated with decreased general health, well-being and fatigue. They are also at risk of rapid weight gain. Restrained eating behaviour can compromise nutrient intake in young women, particularly if associated with meat avoidance. Weight management dietary strategies are therefore required which ensure their high iron and zinc requirements are met.    
Purpose and description
To determine effective dietary strategies for maintaining a healthy weight as well as iron and zinc status in young women. Research was funded following successful applications from researchers with expertise in iron nutrition and young women from the University of Newcastle; the University of Sydney; and Deakin University. Cross sectional studies provided evidence on the prevalence of iron and other nutrient status; dietary intake; and associations with iron and zinc status. Intervention studies evaluated the effectiveness of dietary strategies and the role iron plays in cognition.
Objective
Establish the prevalence of low iron levels in female rural students.To determine the relationship between dietary intake and nutritional status of vitamin B12, iron, zinc and omega-3 fatty acids in female university students.To determine the effect of a higher protein (red meat), moderate carbohydrate, low fat diet on body weight, metabolic, immunological and inflammatory markers, satiety, eating behavior and self esteem compared to a conventional high carbohydrate, low fat diet.To assess the impact of dietary intake and physical activity on iron and zinc status in women blood donors (aged 20 to 40 years).To describe the prevalence of iron deficiency in normal weight compared to obese women and associations with cognitive performance.To determine whether iron supplementation improves cognitive functioning, general health and well-being, fatigue and depressive symptoms in non-anaemic iron deficient women of childbearing age.To determine zinc status and the relationship between iron and zinc status, dietary intake and measures of cognition and mood.To assess the validity of the mobile phone app as a suitable dietary intervention tool for improving intakes of bioavailable iron and zinc.
