About
In the current proposal the investigators seek to evaluate the acute effects of mango intake on blood pressure, blood glucose and insulin in postmenopausal women between 50 and 70 years old.
Full description
Cardiovascular disease (CVD) is the leading cause of mortality in the U.S, and aging is the largest risk factor for vascular diseases. Both male and female adults have increased risk for CVD as they age. For postmenopausal women, this risk is particularly elevated due to the loss of the protective effect of estrogen. It is evident that nutrition plays a crucial role in prevention of chronic diseases such as heart disease, stroke and cancer. Scientific evidence shows that high intake of plant-based food lowers the risk of CVD and many other chronic diseases.
Polyphenolic compounds in fruits and nuts have been the focus of extensive research regarding their potential to reduce risk for a number of chronic diseases. However, fruits and nuts vary largely in the type and amounts of phytonutrients they provide. Mango (Mangifera Idica L.), a commonly cultivated fruit worldwide, is rich in polyphenolic compounds such as gallic acid, mangiferin, quercetin glycosides, ferulic acid, and hydroxybenzoic acid. Many of those bioactive compounds have been found to have anti-diabetic and anti-inflammatory effects in cell models. For instance, mangiferin has been proved to effectively reducing glucose-induced endoplasmic reticulum stress by inhibiting IREα phosphorylation and ROS production in endothelial cells. However, it is unknown if the phytonutrients in mango will demonstrate a similar impact in humans. Therefore, the overall objective of this study is to investigate the effects of acute mango intake on blood pressure and blood glucose.
