Which cooking method best preserves vegetables color and nutrient content?

• A. Boiling
• B. Roasting
• C. Steaming
• D. Frying

Answer: (C)

Preserving color and nutrients comes down to how much nutrients leach into cooking water and how much heat damage occurs. Steaming keeps vegetables above the water, so water-soluble vitamins stay with the food and the gentle heat helps chlorophyll stay green and vibrant. This combination minimizes nutrient loss and color fading compared with other methods. Boiling submerges vegetables in water, which washes away nutrients and dulls color. Frying exposes foods to very high heat in oil, which can break down heat-sensitive vitamins and cause more browning. Roasting uses dry heat at high temperatures, leading to surface dehydration and oxidation that can alter color and reduce some nutrients more than steaming.
