Dietary Interventions for Type 2 Diabetes in South Asian Populations-A Systematic Review

Purpose South Asians face a high burden of type 2 diabetes (T2D). We systematically summarized current research on the efficacy, cultural relevance, and research gaps of nutrition interventions that could be used for treatment in this population. Findings We identified 18 articles published since 2010. Dietary pattern interventions have focused on low-glycemic index (GI) solutions and consistently reported improvement in glycemic management. Trials of nutrition education and counselling had diverse approaches, with those utilizing more intensive interventions generally eliciting better glycemic outcomes. Many studies developed interventions with cultural relevance by including traditional foods, providing materials in the local language, and acknowledging important food-related customs. These adaptations were seen in South Asian countries as well as Western countries hosting immigrants. Summary Data from South Asian countries support low-GI and intensive counselling approaches for the treatment of T2D. Given the high prevalence of T2D in these populous countries, approaches that can reach large numbers of people are needed. In Western countries, more emphasis on providing culturally relevant nutrition therapy is needed.

Automated summary

South Asians face a high burden of type 2 diabetes and therefore require nutrition interventions tailored to their needs. The research findings suggest that low-glycemic index and intensive counseling approaches are effective in South Asian countries, while culturally relevant nutrition therapy is needed in Western countries.
