Impact of Cooking Methods on Nutrient Retention and Chemical Composition of Common Indian Vegetables

Cooking is indispensable in daily diets, but it can significantly alter the chemical composition and nutritional value of vegetables. This paper reviews experimental evidence on how various cooking methods (boiling, steaming, microwaving, pressure cooking, blanching, and frying) affect retention of vitamin C, carotenoids, phenolics, minerals, antioxidant activity, and bioavailability in vegetables. Key findings from global and India-relevant studies are synthesized. In many cases, microwaving and steaming offer superior retention of sensitive nutrients, while boiling and prolonged exposure to water cause leaching and degradation. A nuanced view is presented, considering trade-offs in antinutrient reduction and digestibility improvements. Finally, recommendations for household practices and future research directions are provided.
