5 more inclusion criteria and the exclusion criteria are on the listing.
What it tests, as registered
Prunes; Calcium supplement; Vitamin D Supplement
Registered summary
Dietary interventions of prune consumption during the transmenopausal period are innovative methods to prevent bone loss. Modern medicine does not intervene to prevent or attenuate this highly vulnerable period of bone loss which, if successfully attenuated, can potentially prevent/delay osteoporosis in women. The transmenopausal period represents an opportunistic window for the study because bone loss is at its greatest at this time, with females losing as much as 6-7% of bone.

What it tests, as registered
Dried plums
Registered summary
Prior studies have shown that dietary supplementation with dried plums (also known as prunes) reduces bone loss in postmenopausal women. The purpose of this clinical trial is to understand how dried plums mediate their effects on bone. The main questions the study will answer are: 1. Does adding dried plums to the diet alter immune cell function? 2. Does dried plum alter gut microbes? 3. Does a person's vitamin D status influence this response? Researcher will compare the response following consumption of the normal diet to supplementing the diet with dried plums. Participant will: 1. The full summary is on the listing.
