After women go through menopause, their risk of heart disease increases dramatically. To improve and support heart and blood vessel health among postmenopausal women, researchers at Penn State studied whether beetroot juice can improve how blood vessels function. Results published today in Frontiers in Nutrition indicated that daily consumption of beetroot juice by postmenopausal women may improve blood vessel function enough to reduce future heart disease risk.
Beetroot juice contains high levels of nitrate, which the body converts to nitric oxide . Nitric oxide helps blood vessels expand, making it easier for blood to flow through the circulatory system. The ability of nitric oxide to widen blood vessels is known to be particularly helpful during periods of limited blood flow and oxygen delivery, such as during a heart attack, according to the researchers.
David Proctor, professor of kinesiology and physiology at Penn State, and Jocelyn Delgado Spicuzza, who earned her doctorate in integrative and biomedical physiology from Penn State in May, led an interdisciplinary team of researchers who tested how nitrate-rich beetroot juice impacted blood vessel health in 24 postmenopausal women in their 50s and 60s. "After menopause, women no longer produce estrogen, which helps maintain nitric oxide in the body," said Delgado Spicuzza, first author of the research and current SAFE-T center research project manager. "This loss of nitric oxide production contributes to the substantial .
