Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be randomised to 1 of 3 treatments. 1 acute day (once per week for 3 weeks) of 600ml of red or white de-alcoholised wine given as a drink (to be entirely consumed within 10 minutes of the baseline blood sample being collected) compared with 600ml water as the control (to be completely consumed within 10 minutes of the baseline blood sample being collected).
Each participant will be involved for 3 weeks. On day one of the first week, each participant will be randomised to one of the study drinks or the control drink. At visit 2 (one week later) the participant will be randomised to either one of the remaining study drinks or control drink. At the third visit (one week after visit 2), participants will consume either the remaining study drink or control drink. Participants will refrain from foods and beverages containing polyphenolic compounds for 24 hours prior to each of their 3 weekly visits, and will fast (water allowed) for 10 hours prior to each visit. Week 1: Following the last blood sample being collected on the morning of each visit, the participants will resume their usual diet until 24 hours prior to each of their second and 3rd clinic visits.
There will be two groups of 4 participants on this trial over a six week period. Each group of 4 participants will complete 3 consecutive weeks on the study. The 7 days between each visit is the washout period.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants are screened for inclusion and exclusion criteria and once deemed eligible are randomly allocated into one of the 3 treatments. Allocation was concealed by central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Random allocation using the computer software "Clinstat".
Masking / blinding
Blinded (masking used)
