About this study

Official title: Assessing the Effects of a Daily Prebiotic Fibre Blend on Inflammation, the Gut Microbiome, and Self-Report Measures of Mental Health in Individuals With Metabolic Syndrome

The purpose of the study is to determine whether a daily prebiotic fibre blend can reduce systemic inflammation, dyslipidemia, and self-report measures of mental health in individuals with metabolic syndrome. This study will help shape a larger randomised controlled study (RCT) powered to assess efficacy in a bigger cohort of patients.

Primary outcome measures will explore the efficacy of a prebiotic fibre blend on systemic inflammation. Secondary and exploratory outcomes measures will explore the efficacy of the prebiotic blend on clinical biomarkers associated with cardiometabolic risk factors, microbiota features, and mental health. Using these data, we will also estimate in-year savings for the NHS in the metabolic syndrome population on a per participant basis.

Read the detailed description

Metabolic syndrome is not a chronic disease, but a cluster of metabolic abnormalities including central obesity, insulin resistance, hyperglycemia, hypertension, and dyslipidemia. In the UK, it's estimated that 1 in 3 adults aged 50 years or over meets the criteria of metabolic syndrome. Emerging evidence suggests that metabolic syndrome is associated with low-grade systemic inflammation, which is thought to play a critical role in the subsequent pathogenesis of various metabolic and cardiovascular diseases. In fact, the inflammatory biomarker, high-sensitivity (hs)-CRP, has been shown to be predictive of whether metabolic syndrome progresses to a chronic disease, including cardiovascular disease (CVD), type 2 diabetes (T2D), and cancer mortality. Alongside metabolic disturbances, recent studies have shown that repeated (or long-term) exposure to systemic inflammation is also associated with an increased risk of future depressive and anxiety symptoms, potentially acting via the blood-brain barrier (BBB) interface.

From both a physical and mental health standpoint, it's clear that novel interventions, beyond pharmacotherapy, are needed to reverse the progression of metabolic syndrome, and reduce the risk of developing a long-term chronic disease, and poor mental health.

It is well established that dietary fibre plays a critical role in reducing symptoms of metabolic syndrome, including improvements in insulin sensitivity, glucose metabolism, lipid profile, and blood pressure. Specifically, dietary fibre has been shown to reduce cholesterol levels by binding to bile acids and promoting their excretion, as well as by decreasing the absorption of dietary cholesterol. Additionally, dietary fibre can slow the absorption of carbohydrates and reduce post-prandial glucose spikes, which may contribute to improvements in insulin sensitivity and metabolic health.

Growing evidence also suggests that the mechanisms underlying the benefits of fibre are thought to be mediated, at least in part, by the gut microbiota and their metabolites, such as short-chain fatty acids (SCFAs). A recent systematic review and meta-analysis of 10 randomised controlled trials found that increased intake of dietary fibre was associated with significant improvements in fasting glucose, insulin resistance, total cholesterol, and low-density lipoprotein (LDL) cholesterol levels in individuals with type 2 diabetes. Furthermore, a randomised controlled trial in individuals with metabolic syndrome found that supplementation with a prebiotic fibre blend led to significant reductions in fasting glucose, insulin resistance, and inflammatory markers. Therefore, increasing prebiotic fibre intake may represent a promising strategy for the prevention and management of metabolic symptoms, but remains poorly understood.

Prebiotics are specific types of fibres found in foods like onion, garlic, artichokes, asparagus, leeks, and chicory root. However, to reap the benefits of prebiotics for given health indications, this requires someone to consume roughly 5-10 onions a day. Prebiotic fibre blends (in powder form) are derived from a diversity of plant-based sources, and allows for the study of prebiotic-based benefits in a feasible, easy, measurable, and controlled way.

In this current study, we aim to assess the effects of a daily prebiotic fibre blend on systemic inflammation, the gut microbiome, lipid profiles, and self-report measures of mental health in individuals with metabolic syndrome. The study will be conducted over 12 weeks, and the findings may provide new insights into the potential role of prebiotics in the prevention and management of physical and mental health risk factors associated with chronic disease.

The study population will include adults aged 18-75 years who meet the criteria for metabolic syndrome. To promote the inclusion and diversity of participants across England, this study will be conducted remotely, by posting participants the at-home collection kits (stool and finger prick tests) and online surveys. This gives access to participants who would otherwise not be able to take part in research.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • myota's prebiotic fibre blendDietary supplement

    Each 10g daily serve of supplement contains the following fibres:

    • Fructooligosaccharides
    • Inulin
    • Resistant dextrin
    • Resistant maltodextrin
    • Partially hydrolysed guar gum

Study groupRoleWhat they receive
Prebiotic fibreExperimentalThe treatment group will consume 10g per day of a diverse prebiotic fibre supplement. Supplements are powdered and unflavoured, and given to the participants in 300g packets lasting for 30 days. A 10g scoop is included in each packet and participants are advised to consume one level scoop at any time of the day. Participants are provided with examples on how to consume the supplement (e.g., breakfast cereal, coffee, tea, water).
Receives: Dietary Supplement: myota's prebiotic fibre blend
ControlActive comparatorParticipants are provided with standard of care (dietary advice). Recommendations for diet and lifestyle advice are provided by a UK-registered GP, and follow the Heart UK's Healthy Eating Guidelines. These recommendations emphasise a Mediterranean diet, rich in fruit, vegetables, and healthy fats (omega-3 fatty acids), while reducing refined sugar, salt, processed foods, and alcohol intake. The Mediterranean diet is considered a gold-standard for participants with MetS and poor mental health.

Model description
The current protocol is an open-label parallel randomised controlled trial. Participants will be randomised into one of two study arms: a prebiotic fibre intervention arm or control arm (standard of care - Heart UK's Healthy Eating Guidelines). Participants in the fibre intervention arm will consume 10g of a powdered fibre mix daily for 12 weeks. Both groups will not receive any additional nutrition support beyond Heart UK Healthy Eating Guidelines during the intervention. Participants will be instructed to maintain their normal lifestyle and diet, and avoid consuming other probiotic or prebiotic (fibre-based) products during the study.
