Research Project: MILK & YOGURT VS CALCIUM & VITAMIN D SUPPLEMENTS FOR BONE HEALTH IN POSTMENOPAUSAL WOMEN

Location: Obesity and Metabolism Research Unit

2013 Annual Report


1a.Objectives (from AD-416):
1) Determine if the consumption of 4 servings of milk/yogurt per day improves status of P, Mg, K, and Zn. 2) Determine the contribution of Mg, Zn, P, and K, using statistical models, to bone metabolism.


1b.Approach (from AD-416):
Human intervention study with 22 postmenopausal women in a cross-over design. Interventions include: milk and yogurt vs. calcium and vitamin D supplements. 24-hr. urine samples will be collected at specified times. Diet records will be used to record food intake weekly during the intervention periods and analyzed for nutrient intake above that of the intervention treatment. Urine will be analyzed for bone enhancing nutrients, e.g. Mg, P, K, Zn, and B-12.


3.Progress Report:

This project relates to Objective 1 of the in-house project "to determine the effects of specific foods, nutrients, and food components that promote health and disease prevention in at-risk populations". Clinical study was completed in March of 2013. Diet records have been completed and urinary mineral excretion analysis is finished. Analysis of calcium-41 isotope is pending at Lawrence Livermore National Laboratory.
