The Effect of Daily Mango Intake on Cardiovascular Health
Study Details
Study Description
Brief Summary
In the current proposal the investigators seek to evaluate the acute and short-term effects of mango intake on vascular and platelet function in postmenopausal women between 50 and 70 years old.
Our aims are 1) to determine if two weeks of daily mango intake will result in favorable changes in measures of vascular function, as measured using peripheral arterial tonometry (PAT) and platelet reactivity, in overweight and obese postmenopausal women. 2) to determine if two weeks of daily mango intake will change the fermentation capacity of gut microbiota.
Investigators hypothesize that the daily intake of 330 grams of mango (2 cups) will significantly increase PAT while reducing platelet aggregation after 2 hours and two weeks of daily intake.

Outcome Measures
Primary Outcome Measures
- Acute vascular function [change from baseline to 2 hours compared on days 0 14 and 28]
Comparison of the effect of mango on acute vascular function between baseline and 2-hour postprandial response using PAT.
- Long-term vascular function [Comparison of day 0, 14, and 28]
The effect of mango on long-term vascular function between baseline, two week, and four week time points using PAT
Secondary Outcome Measures
- Acute platelet aggregation [change from baseline to 2 hours compared on days 0 14 and 28]
Comparison of the effect of mango on acute platelet aggregation between baseline and 2-hour postprandial time.
- Long-term platelet aggregation [Comparison of day 0, 14, and 28]
Comparison of the effect of mango on long-term platelet aggregation baseline, two week, and four week time points.
