Brief Summary

Currently, there is a lack of evidence-based prevention strategies for respiratory infection and management of these conditions can be costly to the public. Airway nitric oxide provides a first line of defense against pathogens, and beetroot juice, a source of dietary nitrate, has been shown to elevate nitric oxide. The main objective of this project is to demonstrate that one week of supplementation with beetroot juice elevates airway nitric oxide during stressful periods in young adults and thereby can protect against respiratory viral infections.

Outcome Measures

Primary Outcomes (5)

  • Exhaled Nitric Oxide

    The Fraction of NO in Exhaled Breath (FENO, in ppb) will be measured with an electrochemical gas analyzer (NIOX vero).

    Baseline (non-stress mid point of semester), 1-3 days into active beetroot shots (during final examination period), 4-6 days into active beetroot shots (during final examination period)

  • Viral Polymerase Chain Reaction

    Binary positive/negative test results for a panel of viral and bacterial respiratory pathogens.

    Baseline (non-stress mid point of semester), 4-6 days into active beetroot shots (during final examination period)

  • Wisconsin Upper Respiratory Symptom Survey (WURSS)

    Assess symptoms of acute upper respiratory tract infections (common cold symptoms) by questionnaire

    Baseline (non-stress mid point of semester), 1-3 days into active beetroot shots (during final examination period), 4-6 days into active beetroot shots (during final examination period), 1-3 days after finishing beetroot shots (after final examinations)

  • Adherence monitoring (feasibility)

    Participants will upload a cell phone video of their intake for that day to a secure cloud folder, time stamp in comparison to assigned intake windows provides measure of adherence

    Every day during active beetroot shots (Days 1-7)

  • Burdensomeness

    Follow-up questionnaire will be administered with the online follow-up survey. It explores experience with the best mode of reminder receipt (email or text message), whether the participants guessed their condition, and how burdensome 8 aspects of the study (including daily intake, video recording, upload, questionnaires, physiological assessment) were.

    1-3 days after finishing beetroot shots (after final examinations)

Secondary Outcomes (5)

  • Acute stress

    Baseline (non-stress mid point of semester), 1-3 days into active beetroot shots (during final examination period), 4-6 days into active beetroot shots (during final examination period), 1-3 days after finishing beetroot shots (after final examinations)

  • Cortisol

    Baseline (non-stress mid point of semester), 1-3 days into active beetroot shots (during final examination period), 4-6 days into active beetroot shots (during final examination period)

  • Perceived stress

    Baseline (non-stress mid point of semester), 4-6 days into active beetroot shots (during final examination period)

  • Mood

    Baseline (non-stress mid point of semester), 4-6 days into active beetroot shots (during final examination period)

  • Blood pressure (systolic and diastolic blood pressure) and heart rate

    Baseline (non-stress mid point of semester), 1-3 days into active beetroot shots (during final examination period), 4-6 days into active beetroot shots (during final examination period)

Other Outcomes (3)

  • One-day Food Record

    Baseline (non-stress mid point of semester), 1-3 days into active beetroot shots (during final examination period), 4-6 days into active beetroot shots (during final examination period)

  • Arginase

    Baseline (non-stress mid point of semester), 1-3 days into active beetroot shots (during final examination period), 4-6 days into active beetroot shots (during final examination period)

  • Asymmetric dimethylarginine

    Baseline (non-stress mid point of semester), 1-3 days into active beetroot shots (during final examination period), 4-6 days into active beetroot shots (during final examination period)

Masking Details
Both participating students and assessors will be blinded to the participants' group assignment. Since students and research staff will not know whether their beetroot juice is depleted or not, treatment conditions are double-blinded (juice "shots" will be pre-labeled by study statistician with a participant number based on the pre-study randomization, so neither the staff nor the participant know the contents). Students will also be assured of full blinding of course instructors, including the PIs and Co-Is, to names of study participants.
