Epidemiology doctoral student Mmadili Ilozumba had her manuscript, entitled “Associations between Choline Metabolites and Genetic Polymorphisms in One-Carbon Metabolism in Postmenopausal Women: The Women’s Health Initiative Observational Study,” accepted for publication in the Journal of Nutrition. Mentored by assistant professor in Epidemiology Dr. Ting-Yuan (David) Cheng, Ms. Ilozumba analyzed the associations of single-nucleotide polymorphisms in six genes involved in choline and folate metabolism with plasma concentrations of choline, an essential dietary nutrient, and three choline metabolites. This study helped to elucidate the role of genetics in choline metabolism and will contribute important knowledge to the field of precision nutrition.
