Beneficial health effects of porang (Amorphophallus muelleri): A review


Porang is a plant native to Indonesia that has long been recognized for its various benefits and is increasingly being researched. The high glucomannan content in porang makes porang considered a health-beneficial functional food. This review examines the various beneficial health effects of the porang plant. The method used in writing this journal is collecting data from various sources, including online research journals such as Google Scholar, Pubmed and Science Direct. Based on the journal review, porang was shown to have several beneficial health effects, such as reducing body weight and obesity parameters, lowering blood sugar levels and HOMA-IR, and improving lipid profiles. Glucomannan in porang also has the potential to provide anti-inflammatory, immunomodulatory, anti-tumor, and adjunctive therapy as a laxative and prebiotic.
