Food-Based Nutritional Interventions for the Prevention of Type 2 Diabetes: A Medical and Islamic Perspective

Abstract

Type 2 diabetes mellitus (T2DM) is a major global health concern driven by insulin resistance, β-cell dysfunction, chronic low-grade inflammation, and modifiable lifestyle factors, particularly dietary habits. Culturally sensitive approaches are essential for improving adherence to preventive strategies. Objective: This review examines the role of food-based nutritional interventions in preventing T2DM, integrating evidence-based medical nutrition science with Islamic dietary principles to provide a culturally informed framework. Methods:
A review of published literature was conducted, focusing on clinical trials, epidemiological studies, and meta-analyses evaluating the effects of whole grains, dietary fiber, fruits, vegetables, unsaturated fats, and high-quality protein on glucose homeostasis, weight regulation, and metabolic health. Islamic dietary teachings related to moderation, tayyib (wholesome foods), and preventive health responsibility were also analyzed for their conceptual alignment with modern nutrition science. Main Outcome: The analysis highlights dietary patterns and behaviors that effectively reduce the risk of T2DM and explores how Islamic ethical guidance can enhance adherence and sustainability of preventive interventions. Results: Evidence indicates that diets rich in whole grains, fiber, fruits, vegetables, healthy fats, and high-quality protein improve insulin sensitivity, reduce inflammatory markers, and support weight management. Islamic principles of moderation, food quality, and preventive responsibility complement these strategies, offering a culturally acceptable and ethically grounded approach to disease prevention. Conclusion: Integrating medical nutrition science with Islamic dietary ethics provides a holistic framework for T2DM prevention. Culturally tailored, faith-informed dietary interventions can enhance adherence, metabolic outcomes, and public health impact, particularly in Muslim populations.
