Prune Consumption and Bone Health in Young Women Using Hormonal Contraceptives

January 6, 2025 updated by: Shirin Hooshmand, San Diego State University

The Impact of Consuming California Dried Plums on Bone Health of Young Women Using Hormonal Contraceptives

The primary objective of this study is to determine if 12 months of consuming 50 grams of dried plum daily will prevent bone loss or augment bone accrual of young adult oral contraceptive (OC) users.

Detailed Description

Eligible participants will be assigned among three groups 1) control non-OC users, 2) control OC users, and 3) dried plum OC users. OC users will be randomly allocated to the dried plum OC group, which will consume 50 g dried plum daily for 12 months, or a control group, for which dried plums will not be allowed and no control food will be provided.
