The effect of lifestyle behaviors changes during COVID-19 quarantine on endothelial function. Social distancing was adopted as a way to reduce person-to-person Coronavirus 2019 transmission. However, home confinement may promote lifestyle behaviors changes as unhealthy diet and physical inactivity. Collectively, these unhealthy behaviors are associated with endothelial damage, the first step for the development of cardiovascular diseases. Since nitrate-rich beetroot juice ingestion has demonstrated positive effect on endothelial function due to its effects on nitric oxide bioavailability, its ingestion could be encouraged during COVID-19 quarantine in order to alleviate the potential negative effect of home confinement on cardiovascular health.
