Which vegetables lose nutrients when cooked?

Vegetables like spinach, broccoli, cauliflower, peas, and leafy greens (kale, cabbage) lose significant water-soluble nutrients (Vitamins C, B) and antioxidants when boiled due to leaching and heat, while root veggies (carrots, potatoes) can release more beta-carotene when cooked, and tomatoes become richer in lycopene; however, steaming, microwaving, or using minimal water preserves more nutrients overall, with some compounds even increasing, so quick cooking methods and using cooking water are key.
