Beetroot Enriched Bread, Blood Pressure and Vascular Function

Not Applicable
Completed
Conditions
Hypertension
Interventions
Dietary Supplement: Bread
Registration Number
NCT01706718
Lead Sponsor
University of Reading
Brief Summary

Dietary nitrate is known to lower blood pressure. Beetroot is a rich source of nitrate and could therefore be an important dietary component in the management of hypertension and cardiovascular disease, however consumption is relatively low. We evaluated the effects of beetroot enriched bread ingestion on acute microvascular reactivity, arterial stiffness and blood pressure response in healthy men.
