Vegetables contain a large amount of water, usually 70% to 90%, with the remainder being small quantities of protein, fat, carbohydrates, vitamins, inorganic salts, and fiber. The nutritional value of vegetables is mainly determined by the amount of vitamins B and C, and carotene they contain. According to scientific analysis, the darker the color of the vegetable, the more vitamins B and C, and carotene it contains. Green vegetables are classified as Grade A vegetables by nutritionists, mainly including spinach, rape, cabbage, coriander, bok choy, water spinach, and preserved mustard green.
This type of vegetable is rich in vitamins B1, B2, C, carotene, and various inorganic salts, making it highly nutritious.
Here are 10 methods for detoxifying vegetables:
1. Vegetables that are out of season and brought to market early are often treated with large amounts of pesticides due to being out of sync with the climate, so they should be washed several times.
2. It is best to wash vegetables with plain water. Using salt water for vegetables treated with fat-soluble pesticides may actually make them harder to clean.
3. Do not cut vegetables before washing them to prevent nutrient loss.
4. Vegetables should preferably not be eaten raw. If you must eat them raw, wash them thoroughly multiple times.
5. Blanching vegetables is better than boiling them. Blanching causes some pesticides to evaporate with the steam.
6. When washing vegetables, it is best to soak them in a basin of water first, and then rinse them under a running faucet.
7. For cabbage and napa cabbage, remove the outer leaves first, and then wash the individual leaves.
8. For bok choy and small cabbage, first cut off the roots, and then wash them upright.
9. For bitter melon and small cucumbers, if the skin is not removed, they should be scrubbed with a soft brush.
10. For vegetables like peas, sword beans, chive flowers, and small cucumbers, which have a long harvesting period, a lot of pesticides are sprayed to prevent pests from attacking the immature parts, so they must be washed thoroughly multiple times.
