Study Summary
The purpose of this study is to increase our understanding of how much choline humans need to get from their diet. Choline is an essential nutrient found in many foods, including eggs and milk. In addition to dietary sources, choline can be made in the liver. Choline is important in making membranes or wrappers for all the cells in the body and for making chemicals that allow nerve cells to work properly. In a previous study we found that the dietary requirement for choline varies greatly from person to person. This was caused, in part, by how much estrogen a person has and their genetic makeup. We are conducting this study to explore how estrogen levels and specific differences in genes influence choline requirements so that we can refine the dietary recommendations for this nutrient.
Interventions
- OTHER Estrogen plus choline depletion diet
- OTHER Placebo plus choline depletion diet
- OTHER Pre-menopausal women with SNPs given a low choline diet
