A Systematic Review on the Prospective Significance and Recommendations of Pearl Millet (Pennisetum glaucum) for Diabetes Mellitus

Diabetes Mellitus (DM) represents a significant global health challenge, characterized by elevated blood glucose levels and associated metabolic complications. Dietary management is a cornerstone in the control and treatment of diabetes, with increasing focus on the role of whole grains in diabetic diets. This systematic review explores the prospective significance of pearl millet (Pennisetum glaucum), a traditionally important but often underutilized grain, in the management of DM. Through a comprehensive analysis of existing literature, including randomized controlled trials, observational studies, and nutritional analyses, this review assesses the impact of pearl millet on glycemic control, insulin sensitivity, lipid profiles, and overall metabolic health in the context of diabetes. The nutritional profile of pearl millet, particularly its low glycemic index, high fiber content, and rich micronutrient composition, positions it as a potentially beneficial dietary component for individuals with DM. The review also addresses practical considerations for incorporating pearl millet into diabetic diets, alongside recommendations for portion sizes and preparation methods. Despite promising findings, the review identifies gaps in current research, particularly the need for more extensive clinical trials to establish conclusive evidence. This review culminates in recommendations for future research directions, emphasizing pearl millet’s potential as a functional food in diabetes management and the necessity for greater scientific exploration into its specific benefits.
