About this study

Official title: Impact of Dietary Fiber-Rich Kodo Millet Porridge Supplementation on Gut Microbiome and Metabolic Syndrome

Dietary fiber are components in foods that are not digested by human gastrointestinal enzymes (alpha amylase and alpha glucosidase) but are instead broken down and fermented by gut microbes. The byproducts generated during fermentation in the large intestine, primarily short-chain fatty acids (SCFA), bile acids, indoles, and their derivatives, circulate through the circulatory system to the liver, lungs, brain, adipose tissue, and muscles, where they modulate metabolism (suppress lipogenesis and alleviate insulin resistance) and immune function. Individuals who are overweight or obese frequently exhibit gut dysbiosis, characterized by lower SCFA producing commensals. This condition predisposes them to metabolic disorders such as insulin resistance, dyslipidemia, and hypertension, and contributes to conditions including type 2 diabetes, cardiovascular disease, and metabolic dysfunction-associated steatotic liver disease. Preclinical and clinical research have demonstrated that the consumption of fiber-rich foods maintains or restores gut microbiota health and diminishes the risk of metabolic disorders. Kodo millet (Paspalum scrobiculatum), a small millet, is rich in dietary fiber and we have developed a palatable kodo millet porridge beverage enriched with polyphenols and dietary fiber. The purpose of this study is to examine the effects of consuming Kodo millet porridge beverage as a nutritional supplement for 3 months, on gut microbiome richness (composition and diversity) and metabolic health in overweight or obese people.

Read the detailed description

This single-center, open-label, pre-post interventional trial enrolls 50 people with a BMI ≥ 25 kg/m² (overweight or obese) and no previous history of cardiovascular, renal, or neurological conditions to consume 200 ml of Kodo millet porridge daily for 12 weeks. The study will examine pre- and post-intervention alterations in individual gut microbiota composition through 16S sequencing, as well as circulatory levels of short-chain fatty acids (SCFA), glycemia, lipidemia, triglyceride-glucose index (a measure of insulin resistance), plasma antioxidant capacity, and markers of oxidative stress and inflammation.
