During cooking, care must be taken to preserve what in vegetables?

• A. Color only
• B. Texture only
• C. Nutritional value only
• D. Color, texture, and nutritional value

Answer: (D)

Cooking affects how vegetables look, feel, and how nutritious they are. The color comes from pigments that can fade with heat, so choosing quick methods that minimize exposure—like blanching briefly and then shocking, steaming, or light sautéing—helps keep vibrant color. The texture depends on the cell walls and softening that heat causes; overcooking makes vegetables mushy and loses that pleasing crisp-tender bite. Nutritional value, especially water-soluble vitamins, can diminish with long cooking times or when vegetables are boiled in lots of water, leading to nutrient loss through leaching. By using gentle techniques, short cooking times, and minimal water, you preserve color, texture, and nutrients. That’s why the best choice reflects all three aspects rather than just one.
