ReJUICE your pain: The effect of dietary advice and a dietary supplement on pain outcomes in people experiencing chronic pain

Two intervention components will be tested: 1) Personalized dietary advice provided via telehealth and 2) Dietary supplement. The dietary supplement is a fruit juice. Two fruit juices will be used 1) Active fruit juice (high in anthocyanins) and 2) Placebo fruit juice (no anthocyanins). Participants will be randomized into one of four groups Study arm 1: Personalized dietary advice and active fruit juice Study arm 2: Personalized dietary advice and placebo fruit juice Study arm 3: Waitlist control and active fruit juice Study arm 4: Waitlist control and placebo fruit juice Personalized dietary advice: Participants will receive up to three 30-45 minute consultations (2 recommended, 1 optional) with an Accredited Practicing Dietitian (APD). This will be provided via Avaya Scopia (the telehealth software used by Hunter New England health) or via phone calls. Prior to the consult, participants will complete the Australian Eating Survey (AES) Food Frequency Questionnaire which generates a report comparing dietary intake to national guidelines. Participants will be sent their AES report prior to the first consultation. They will also be asked to complete a personalised nutrition questionnaire (PNQ) to identify factors which may affect their eating behaviors which will allow the APD to prioritize barriers that may affect each participant. There is a toolbox associated with the PNQ which lists intervention strategies and resources linked with each factor. The APD used the PNQ and toolbox to discuss strategies and goal setting. A summary of the session and links to relevant resources will be emailed to each participant at the end of the session. The resources include websites and handouts which were sourced from government departments, The Dietitians Association of Australia, Nutrition Education Materials Online, Australian Healthy Food Guide and Practice-based Evidence in Nutrition Fruit juice: participants will receive 42X 250ml bottles of fruit juice to consume one per day for a 6 week period. The anthocyanin content of this juice ranges from approximately 30mg/100g to >100mg/100g depending on the conditions of the season when the fruit was grown. A tick-box calendar will be provided to monitor compliance.
