How does cooking vegetables affect their nutrient levels?
Cooking vegetables can enhance taste and digestibility but may reduce nutrient levels, especially heat-sensitive and water-soluble ones. Boiling greens for 10 minutes can lead to a 15-20% drop in antioxidant capacity, with vitamin C being the most affected nutrient.
What is the impact of refrigeration on preserving nutrients in greens?
Refrigeration is crucial to preserve nutrients in greens. Drying can cause up to a 90% loss of vitamin C, highlighting the importance of proper storage conditions to maintain the nutritional value of vegetables.
Which cooking methods are more favorable for retaining nutrients in vegetables?
Different cooking methods impact nutrient retention differently. Steaming and microwaving are more favorable than boiling, especially for cruciferous vegetables like watercress, which is rich in glucosinolates.
What happens to the antioxidant capacity of greens when boiled for 10 minutes?
Boiling greens for 10 minutes can lead to a 15-20% drop in antioxidant capacity. Vitamin C is the most affected nutrient, while beta carotene tends to stay in the leaves despite the cooking process.
