Abstract

Diabetes is a growing global health issue, with diet playing a crucial role in prevention and management. Protein, an essential nutrient for growth, repair, and metabolism, can significantly influence diabetes risk and control. High-protein diets, especially those rich in animal proteins, have been linked to increased risk of type 2 diabetes, while plant-based proteins may offer protective benefits. Studies suggest that excessive animal protein intake, particularly from red and processed meats, can increase diabetes risk due to higher saturated fat content. Conversely, plant-based proteins, such as soy, tofu, and nuts, are associated with improved insulin sensitivity and reduced inflammation. Protein supplements—especially whey and soy proteins—are known to help maintain muscle mass and improve metabolic indicators. However, the evidence supporting these benefits remains limited, and excessive protein intake may increase risks of other negative effects, such as impaired kidney function. Therefore, caution is advised when using these supplements. A balanced approach that emphasizes plant-based proteins while moderating animal protein intake is recommended for diabetes prevention and management. Future research should focus on personalized dietary strategies for optimal health outcomes.
