Blood samples will be collected for the preparation of plasma and peripheral blood mononuclear cells (PBMCs) for the analysis of anthocyanin metabolite concentrations, transcriptomics and CVD risk markers. Urine samples will be collected and urinary excretion of anthocyanin metabolites will be quantified. Other measurements will include pulse wave analysis, pulse wave velocity, central blood pressure, waist and hip circumference, blood glucose, glycated haemoglobin (HbA1C) and insulin concentrations, and various measurements using the TANITA machine which include weight, fat mass, muscle mass, fat percentage, fat-free mass, total body water, bone mass, metabolic age, basal metabolic rate, visceral fat rating, and degree of obesity. All measurements and samples will be taken at baseline and post intervention for each phase of the study.
