1. Choose pesticide-free vegetables
Edible fungi grown in the wild or artificially cultivated, as well as various artificially cultivated bean sprouts, are not treated with pesticides and are very safe vegetables. Root vegetables whose fruits grow in the soil, such as fresh lotus root, potatoes, taro, carrots, and winter bamboo shoots, are also rarely treated with pesticides, leaving almost none on the vegetables. If you have a small plot of land at home, grow some yourself for peace of mind.
2. Wash vegetables before eating
Pesticides tend to remain on vegetables. For vegetables that can be peeled, peel them whenever possible. For those that cannot be peeled, soak them in clean water for 20-30 minutes first to allow the pesticides to dissolve thoroughly, then rinse repeatedly with clean water. Alternatively, soak the vegetables in rice washing water for 10 minutes, discard the soaking liquid, and then rinse repeatedly with running water; the alkaloids in rice washing water are effective at dissolving pesticides. Or, soak the vegetables in hot water at 80°C or higher for 2 minutes to quickly dissolve the pesticides, then rinse thoroughly with clean water. Or, place fruits and vegetables in a basin, add an ample amount of water, then stir in baking soda and soak for 10 minutes before rinsing off with clean water.
3. Eat more deeply colored vegetables
Research has found that the nutritional value of vegetables is closely related to their color. Generally, darker-colored vegetables are more nutritious. For example, fresh dark green vegetables have higher levels of vitamin C, carotene, and inorganic salts. In addition, carotene is also found in higher amounts in orange, yellow, and red vegetables. Studies have shown that green leafy vegetables help prevent appendicitis, and red vegetables can help relieve the symptoms of colds and flu.
4. Eat more fresh, seasonal vegetables
Off-season vegetables are mainly greenhouse-grown. Although they may look attractive and be large in size, their nutritional value is not the same as fresh, seasonal vegetables. Off-season vegetables are not as nutritious as fresh, seasonal ones and their taste is also inferior. For example, tomatoes may be treated with growth hormones during flowering and coloring, which are not good for the body.
5. Eat vegetables of all colors
Vegetables mainly come in green, yellow, or red colors. Green vegetables are those with a high chlorophyll content and are generally green in color, such as spinach, chives, celery, cilantro, and green peppers. Yellow or red vegetables are those that are primarily colored by carotenoids or flavonoid pigments and are generally yellow or red, such as carrots, daylilies, potatoes, melons, radishes, and tomatoes.
6. Eat fresh vegetables even during the off-season
Nutrition experts point out that regardless of the season, vegetables should be eaten fresh. This is because all vegetables contain vitamin C, and its content is closely related to the freshness of the vegetable. Generally, the longer a vegetable is stored, the more vitamin C it loses. Therefore, during the off-season, do not buy and store too many vegetables at home. It is best to buy and eat them fresh to ensure you are consuming fresh vegetables.
