Participants will participate in a 1-2 week screening period followed by a 1-2 week baseline period. At the end of baseline randomization to 1 of 3 groups will occur (Ca2+ and VitD only; 50g Dried Plums/day and Ca2+ and VitD; 100g Dried Plums/day and Ca2+ and VitD). Dried plums and Calcium/Vitamin D supplements will be provided to participants for the duration of the intervention. At the beginning of the 52 week intervention participants will begin consumption of dried plums and will be given a run in period where the number of dried plums consumed per day increases slowly to minimize the side effects felt by the participants. The dried plums will be consumed as snacks in the morning, midday, and in the evening. Participants will visit the laboratory for testing every 4 weeks during the 52 week intervention, with more testing occurring during weeks 12, 24, 36, and 52 than the other testing periods.
