Study Details

This pilot study aims to explore the potential benefits of consuming Greek bottarga (grey mullet fish roe) in individuals with at least one metabolic abnormality (low HDL cholesterol, high LDL cholesterol, high triglycerides, obesity, or HbA1c ≥ 5.7%) or a diagnosis of diabetes. Before initiating the crossover randomized controlled trial (RCT), the investigators will conduct a preliminary dose-testing study in five adults with at least one metabolic abnormality. Participants will undergo clinical assessments before and after the dietary intervention to evaluate changes in metabolic health markers. Following this phase, the investigators will proceed with a randomized, controlled crossover trial involving 20 eligible adult participants. This main study phase will compare the metabolic effects of daily bottarga supplementation with those of a calorically matched dairy product over an 8-week intervention period, with a 2-week washout period between interventions. The investigators anticipate that bottarga supplementation will improve lipid profiles, inflammation markers, and insulin resistance, thereby supporting the potential use of sustainable blue foods as part of a healthy diet.

Arms

  • Experimental: Bottarga supplementation (intervention group)
    Ten participants with at least one metabolic abnormality (low HDL cholesterol, high LDL cholesterol, high triglycerides, obesity, or HbA1c ≥ 5.7%) or a diagnosis of diabetes will be randomly allocated to 8 weeks of daily bottarga supplementation (20 grams/day) as an initial treatment. Baseline assessment measures will be repeated, followed by a 2-week wash-out period. Then, assessment measures will be repeated followed by 8 weeks of daily cream cheese supplementation (28 grams/day), followed by final assessment measures.
  • Sham Comparator: Cream cheese supplementation (control)
    Ten participants with at least one metabolic abnormality (low HDL cholesterol, high LDL cholesterol, high triglycerides, obesity, or HbA1c ≥ 5.7%) or a diagnosis of diabetes will be randomly allocated to 8 weeks of daily cream cheese supplementation (28 g/day) as the initial intervention. Baseline assessment measures will be repeated, followed by a 2-week wash-out period. Then, assessment measures will be repeated, followed by 8 weeks of daily Bottarga supplementation (20 g/day), followed by final assessment measures.

Primary Outcome Measure

Mean change in fasting glucose [ Time Frame: From baseline (start of the intervention) to Week 8 (end of the initial intervention period, prior to crossover), and from Week 10 to Week 18 (end of the second intervention period following crossover). ]
