- Brief Summary
One of the targeted objectives of Healthy People 2020 is to reduce iron deficiency among women of reproductive age (WRA). Consuming foods rich in iron and/or oral iron supplementation is typically recommended to improve iron status; however, global rates of iron deficiency remain high. Thus, nutritional strategies to improve/maintain iron status are warranted. Dietary iron is found in two different forms: heme and non-heme iron. Non-heme iron is found in plant-based sources and is commonly used as a supplement and food fortificant. Absorption of non-heme iron is low compared to heme iron, which is found in animal sources, such as beef. Studies have also demonstrated that beef contains an unidentified factor that stimulates the absorption of non-heme iron. The primary objective of the proposed study is to determine the effects of incorporating daily meals containing beef or plant-based alternative with or without an iron supplement on indicators of iron status in iron-deficient WRA.

- Primary Outcome Measures
Name Time Method Iron status Change from day 0 and day 56 Plasma ferritin, soluble transferrin receptor, transferrin saturation, hemoglobin and hematocrit will be measured to determine iron status. Changes in measures of iron status during the intervention will be compared between groups.
- Secondary Outcome Measures
Name Time Method Profile of Mood States (POMS) Change from day 0 and day 56 The POMS questionnaire will be used to assess the overall mood state of the participants. Changes in the POMS during the intervention will be compared between groups.
Appetite Change from day 0 and day 56 Subjective appetite and satiety will be assessed before and after the lunch meal using visual analog scales.
Plasma vitamin B-12 Change from day 0 and day 56 Changes in the plasma vitamin B-12 during the intervention will be compared between groups.
Weight Change from day 0 and day 56 Changes in body weight during the intervention will be compared between groups.
Blood pressure Change from day 0 and day 56 Changes in blood pressure during the intervention will be compared between groups.
Metabolic biomarkers Change from day 0 and day 56 Changes in blood lipids, glucose, and insulin during the intervention will be compared between groups.
Plasma choline Change from day 0 and day 56 Changes in the plasma choline during the intervention will be compared between groups.
Body composition Change from day 0 and day 56 Body composition (fat mass, fat-free mass, and total body water content) will be determined using single frequency bioimpedance spectroscopy (BIS). Changes in body composition during the intervention will be compared between groups.
Plasma zinc Change from day 0 and day 56 Changes in the plasma zinc during the intervention will be compared between groups.
