The Effect of Daily Mango Intake on Cardiovascular Health

September 1, 2022 updated by: University of California, Davis

The Effect of Daily Mango Intake (Mangifera Indica L.) on Cardiovascular Health

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
