This epidemic is largely driven by a distinct \"Asian phenotype\" characterized by reduced insulin secretion capacity even at lower BMIs and a diet heavily centered on high-glycemic index (GI) white rice. While brown rice offers superior nutritional benefits, its global and local adoption remains low due to entrenched cultural preferences, shorter shelf life, and sensory barriers.\n\nWhile the link between high-GI carbohydrates and metabolic dysfunction is well-documented, there is limited clinical evidence on the effects of \"functional\" white rice varieties specifically those engineered to combine low GI properties with significantly enhanced protein content on long-term glycemic control, metabolic and gut microbiome health in Asian populations. The importance of this research lies in its evaluation of a culturally seamless substitution strategy. By replacing conventional white rice with Low-GI (LGI) and High-Protein Low-GI (LGI-HP) varieties, the HARVEST study addresses the metabolic burden of prediabetes without requiring major behavioral shifts. The findings will provide vital mechanistic insights into glucose regulation, insulin sensitivity, and microbial dysbiosis, to provide the evidence based for nutritional strategies for T2D prevention and management.",[65],"Prediabetes \u002F Type 2 Diabetes",[67,68,69,70],"Prediabetes","Type 2 Diabetes prevention","Nutrition","Metabolic dysfunction","NOT_YET_RECRUITING","2026-06-17",{"date":74,"type":75},"2026-06-23","ACTUAL",{"date":77,"type":59},"2026-08-10",{"date":79,"type":59},"2029-04-30",{"name":5,"class":6}]
