Influence of Mango Intake of Skin Health in Postmenopausal Women

Not Applicable

Completed

• Conditions: Wrinkle; Skin Red
• Interventions: Other: 16 weeks mango intake

• Registration Number: NCT03590756
• Lead Sponsor: University of California, Davis

Brief Summary

This study aims to investigate the effects on 16 weeks of mango intake on skin health in postmenopausal women. Half of the participants will receive 85g portions of mangoes while the other half receive 250g portions of mangos. Participants will be instructed to consume the specific portion 4 times a week, for a total duration of 16 weeks.

Detailed Description

Mangoes are rich in carotenoids, flavonoids, vitamins and other active phytochemicals such as resistant starches. Although a role of mangoes in skin health has long been advocated in traditional medicine, little scientific research has been conducted.

We hypothesize that 85g (0.5 cups) of mango intake for 16 weeks will have minimal impact on skin health, while 250g (1.5 cups) of mango intake will produce significant benefits.
