Psyllium Husk: A Comprehensive Review of its Functional Properties, Health Benefits, Mechanisms of Action, and Potential Adverse Effects
摘要
This review aims to provide insights into the various characteristics of psyllium husk (Plantago ovata). Specifically, the review focuses primarily on its role in managing chronic disease and the potential mechanisms responsible for these health benefits.
Recent FindingsThe studies have highlighted the multifaceted functional properties of psyllium husk, including its high water-holding capacity, gel-forming ability, and viscosity, which contribute to its efficacy in promoting gastrointestinal health. The consumption of psyllium husk may improve glycemic control, reduce cholesterol, and enhance bowel function. The various mechanisms responsible for health benefits include the binding of bile acids, modulation of the gut microbiome, enhanced satiety, and delayed gastric emptying. Psyllium consumption promotes the abundance of Bifidobacterium and Lactobacillus spp., thereby increasing the production of short-chain fatty acids (SCFAs). However, several adverse effects were observed, including bloating, allergic reactions, and gastrointestinal obstruction (resulting from inadequate water consumption).
SummaryPsyllium husk can be used as an adjunct therapy in managing body weight, hypercholesterolemia, type 2 diabetes, and gut health. It is generally considered safe; careful consideration of dosage and hydration is necessary to minimize adverse effects. Further research is required to optimize dosage and investigate the long-term effects on metabolic health.
