NCT01717820

Brief Summary

The purpose of the study is to provide whole-grape powder or a placebo as a supplement to postmenopausal women for 12 weeks to determine the effects on body composition and bone formation.It is hypothesized that 12 weeks of supplementation with whole-grape powder will decrease body fat via resveratrol's positive effects on metabolism and negative effects on fat cells.

Outcome Measures

Primary Outcomes (1)

  • Effect of freeze-dried whole-grape powder on body composition in postmenopausal women

    Body composition measurements will be taken to assess the participant's percentage of fat and lean tissue. Height and weight of participants will be measured with a stadiometer and a calibrated electronic scale. In addition, waist circumference will be measured. The waist-to-hip ratio at the minimal waist and maximal hip locations will be measured with a steel measuring tape. Height (m) and weight (kg) will be used to measure the participant's body mass index. Participants will undergo a dual energy X-ray absorptiometry (DXA) scan. Total bone mineral density, percentages of fat and lean body mass and regional values of the android or gynoid regions will be measured.

    12 weeks

Secondary Outcomes (2)

  • Effect of freeze-dried whole-grape powder on biomarkers of inflammation, adipose metabolism, and bone formation in post menopausal women.

    12 weeks

  • Effect of freeze-dried whole-grape powder on bone resorption in postmenopausal women

    12 weeks

Study Arms (1)

Freeze-dried whole-grape powder

EXPERIMENTAL

Freeze-dried whole-grape powder (46g/day)will be provided to participants for 12 weeks.

Dietary Supplement: Freeze-dried whole-grape powder

Interventions

Participants are provided the equivalent of two servings per day of freeze-dried grape powder in a double-blind, placebo controlled, randomized design to determine the impact of the phytochemical, resveratrol, on biomarkers of adipose metabolism and bone metabolism.
