Therapeutic Efficacy of Soy-Derived Bioactives: A Systematic Review of Nutritional Potency, Bioactive Therapeutics,...

Soybeans (Glycine max) are nutrient-dense legumes and a high-quality plant-based protein source containing all essential amino acids. With a protein content of 36-40%, soy surpasses many other plant-derived proteins in nutritional value. Its bioactive components, particularly peptides and isoflavones, contribute to reducing inflammation, oxidative stress, and the risk of chronic diseases. In undernourished regions such as Pakistan, where protein-energy malnutrition is prevalent among women and children, soy offers a sustainable and cost-effective nutritional intervention. This review synthesizes findings from biochemical analyses, nutritional profiling, and clinical trials evaluating the impact of soybean protein and its bioactive compounds on growth, metabolic health, immune function, and disease prevention. Emphasis was placed on studies relevant to food-insecure populations and technological innovations enhancing soy product bioavailability. Soy protein has been shown to have positive effects on hormonal regulation, cardiovascular health, cognitive function, and immune support. Technological approaches such as fortification and fermentation improve nutritional bioavailability and sensory acceptance. The integration of soy into local diets enhanced nutritional adequacy, promoted environmental sustainability, and aligned with Sustainable Development Goals. Soybeans represent a sustainable, nutrient-rich solution to combat protein-energy malnutrition in vulnerable communities. Their high-quality protein profile, therapeutic properties, and adaptability to local food systems make them an effective strategy for improving public health and supporting environmental resilience.
