China's traditional Chinese medicine to 

        In recent years, the pollution caused by pesticide residues on vegetables, after eating lead to acute poisoning incidents occur frequently, so eat vegetables also have to pay attention to environmental protection. As consumers should learn to avoid pollution, so as to avoid the illness. 
 
        Don't eat vegetables abnormal shape and color 
 
        Shape and color of normal vegetables, usually in conventional cultivation, is not processed by hormones and other chemicals, safe to eat. Abnormal vegetables may be treated with hormone, such as wider leek leaves hypertrophy, may in the cultivation process used hormone, not used hormone leek leaves narrower, fragrance. 
 
        Some vegetables color is not normal, also want to pay attention to, such as the abnormal edamame green, before the harvest may spraying or soaking a ammonium phosphate pesticide, unfavorable choose and buy. 
 
        Don't eat "buggy" and "medicine" more vegetables 
 
        In many vegetables, some vegetables is particularly favored by pests, can be called "bug more vegetables"; Some vegetable pests don't like to eat, can call it "little worm vegetables". Is determined by the vegetables of different ingredients and the specificity of odour. Bug more vegetables, "famous" such as green vegetables, Chinese cabbage, cabbage, cauliflower, less vegetables are crown Daisy, lettuce, celery, carrots, Onions, garlic, leek, green Chinese onion, coriander, etc. 
 
        Bug more vegetables by pests, often have to prevention and control of spraying, certainly will become a pollution "medicine more vegetables", at ordinary times should be less as far as possible choose vegetables. In low temperature season, however, due to the pest dormant winter, pesticide spraying is stopped, then a small amount of edible insect more vegetables also just as well. 
 
        Don't eat the fertilization rates by a large vegetable 
 
        , because of the large chemical fertilizer seems particularly nitrogen (such as urea, ammonium sulfate, etc.) seems too big, will cause the vegetable nitrate pollution is more serious. Nitrate itself to toxicity is not big, but along with the vegetables into the gastrointestinal tract and will be restored as nitrite, and nitrite with secondary amine to form the ammonium nitrate in the gastrointestinal tract, it is a kind of carcinogenic substance. 
 
        By the authoritative department of listed vegetables after testing found that all kinds of vegetables nitrate accumulation intensity, from strong to weak law is: root vegetables, potato, taro, green leafy vegetables, cabbage, Onions and garlic, beans, melons, solanaceous fruit, edible fungus. Nitrate content is up to tens of times, the law is the root, stem and leaf vegetables (vegetation) pollution is far higher than flowers, fruit, seeds (reproductive), it could be a biological world widespread protective response. This is very useful. It can guide us the correct consumption of vegetables, as far as possible to eat more fruits and edible fungi, such as cucumber, tomato, green soy bean, mushrooms, etc. 
 
        If you like to eat leaf vegetables, also don't be too hard on yourself, pay attention to supplement some vitamins. Because vitamin C can prevent the formation of nitrite amine, can reduce of the potential danger of leaf vegetables. (psoriasis),
