Role of beetroots in oxidative stress and vascular relaxation in ovariectomized rats

The onset of hypertension in women is known to peak dramatically after menopause, partly due to decreased estrogen levels. It is well known that postmenopausal estrogen therapy can cause many adverse effects, and there is growing interest in using dietary products as potential treatment options. Dietary nitrates in beetroot may raise blood nitric oxide levels. We tested the hypothesis that beetroot can improve the oxidative stress and vascular relaxation responses in a model of an ovariectomized rodent.
