Impact of Egg Consumption on Carotenoid and Vitamin D Bioavailability in Pre- and Post-menopausal Women
Completed · Not applicable
Conditions studied: Menopause
In brief
The 2010 Dietary Guidelines for Americans emphasizes consumption of 4.5 cups of fruits and vegetables daily but the average intake of US adults is only 2.6 cups. This low consumption of fruits and vegetables results in a limited availability of certain nutrients found in these foods such as carotenoids. Dietary carotenoids have health-promoting properties and are known to fight against disease. Although, maintaining adequate vitamin D status is critical for overall skeletal health and the prevention of osteoporosis, vitamin D insufficiency is also widespread in the United States. Eggs, egg yolk in particular, are known to be a good source of lipid and may improve the absorption of carotenoids and vitamin D found in co-consumed vegetables in young and older women. Therefore, the investigators are interested to see if consuming eggs with cooked vegetables will increase carotenoids and vitamin D absorption.
