Beetroot rich in inorganic nitrate may be used as dietary supplementation or functional food to improve endothelial function via reduced expression of harmful free radicals, a respectable institute study illustrated.
The endothelium is a thin membrane that lined the inside of the heart and blood vessels with function in controlling vascular relaxation and contraction, as well as enzymes that control blood clotting, immune function, and platelet adhesion.
Endothelial dysfunction, due to the inability of the arteries to dilate fully, may exhibit high blood pressure, diabetes, and high cholesterol.... promoting stroke and heart attacks.
Beet, best known as the beetroot or garden beet, belonging to the amaranth family, is a perennial plant with leafy stems growing to 1–2 m tall.
A total of 20 healthy overweight and slightly obese men with a BMI between 28 and 35 kg/m(2) received in random order a mixed meal of 56.6 g of fat with beetroot juice or a control drink, oral administration of beetroot juice (140 mL) with approximately 500 mg dietary nitrate group, showed a significant improvement of postprandial endothelial function in compared control.
The efficacy of beet juice in attenuated postprandial impairment of flow-mediated dilation (FMD) following a mixed meal, is probably due to the expression of increased plasma NO concentrations in the bloodstream, according to the Maastricht University Medical Center.
Furthermore, beetroots with biological activity provided a natural source of nitric oxide (NO) in reduced risk of endothelium dysfunction inducing the imbalance between vasodilation and vasoconstriction of arterial vessels.
The study also suggested that phytochemical betalain isolated from beetroot may also hold a significant effect in maintaining healthy endothelium function, acting simultaneously with increasing levels of nitric oxide (NO).
More importantly, the review database of literature from MEDLINE, EMBASE, and Scopus databases from inception until November 2014, 9 crossover trials and three parallel trials met inclusion criteria, including a total of 246 participants with 10-64 participants per study, also indicated the efficacy of inorganic nitrate and beetroot consumption in reduced risk of cardiovascular disease by improved vascular function. But the effect on endothelial function was significantly associated with the dose depended of inorganic nitrate, found abundantly in the vegetable
The evidence indicated that beetroot may be considered a promising therapeutic treatment in ameliorating the risk of cardiovascular disease through the improvement of vascular and endothelial functions.
