Anthocyanins: These pigments are abundant in purple-fleshed varieties and are powerful Antioxidants with strong Anti-inflammatory and Cardioprotective effects, helping to protect blood vessels and reduce oxidative stress.

Dietary Fiber (Soluble and Insoluble): Contributes to digestive health, acts as a prebiotic, and provides a mild Laxative effect. The soluble fiber helps in modulating blood sugar levels (Hypoglycemic) and lowering cholesterol (Hypolipidemic).

Complex Carbohydrates: Provide sustained energy release. The slow digestion of these carbs contributes to its hypoglycemic property, making it a favorable food for blood sugar management compared to other high-glycemic carbohydrates.

Vitamins and Minerals: Rich in Vitamin A (from carotene), Vitamin C, Manganese, and Potassium. These support its role as a powerful Nutritive Tonic, aiding in immune function, electrolyte balance, and overall tissue health.
