Outcome measures
Primary outcome
The primary parameter will be the increase in plasma nitrate concentrations from baseline fasting levels, which will be measured at 3h post-ingestion on day 1, 4, and 7 of the intervention.
Secondary outcome
Plasma nitrite concentrations, salivary nitrate and nitrite concentrations, blood pressure, urinary nitrosamines, and dietary intake will be determined throughout the trials as secondary parameters.
Study objective
We hypothesize that dietary strategies focusing on increased intake of nitrate rich vegetables lead to a similar increase in plasma nitrate (and nitrite) concentration when compared to beetroot juice supplementation and, as such, may represent a feasible alternative for increasing dietary nitrate intake.
Study design
day 1, 4, and 7
Intervention
Participants will receive 1-wk of dietary guidance in which they will be provided with a sufficient amount of vegetables, representing 400 mg (6.5 mmol) nitrate per serving (i.e. each day), including information about nitrate and nitrate rich recipes. In a randomized cross-over manner, participants will also follow a 1-wk supplementation protocol in which they will ingest 400 mg (6.5 mmol) nitrate per day in the form of concentrated red beetroot juice. Both trials will be separated by a 1-wk washout period.
