People are most worried about pesticides contamination when they eat vegetables. In general, vegetables that are vulnerable to pests and diseases are more likely to use pesticides. Some foods or their own “strong physique†or excellent growth environment can be grown without the protection of too many pesticides. So, what kind of dish can be “sludgeless without dyeing�
The first category: pest-resistant
It is a vegetable that is not susceptible to insect pests. They have strong resistance and therefore use less pesticides such as cabbage, leeks, celery, cauliflower, pepper, radish, etc.
The second category: long in the soil
The second type of vegetables that are not easily contaminated are edible vegetables that grow in the soil, such as alfalfa, potatoes, taro, kohlrabi, and sweet potatoes.
The third category: wild-born
Vegetables that are most easily contaminated with pesticides
Most leafy vegetables will use pesticides more often, such as cabbage, rape, chicken feathers and so on. When eating these vegetables, wash carefully.
Many people think that vegetables with insect eyes use fewer pesticides and are therefore safer. Do you not know, with the popularization of pesticides, pest resistance is also increasing.
Moreover, some pesticides can not prevent the survival of insects, but they do harm to humans. Therefore, eating vegetables with insect eyes can not be taken lightly.
In addition, the pesticide residues in green leafy vegetables are also seasonal, and in general summer vegetables are more pesticides.
Vegetable dish pedicure
Professor Liu Zhenfang of the Department of Health Nutrition at Taipei Medical University pointed out that vegetables and vegetable pedicles are the most pesticide residues. For example, the cabbage roots near the root of the Chinese cabbage and the bell peppers are connected to the sunken portions, and the pesticides are more than other parts. It is best to lose them when eating.
Why do the pesticides remaining on vegetables accumulate in these areas? The relevant researchers of the National Vegetable Engineering Technology Research Center pointed out that this is related to the growth pattern of the vegetables and the spraying method.
Taking Chinese cabbage as an example, first of all, because of gravity, pesticides will flow down the leaves and vegetable stalks and gather under the vegetable stalks. Therefore, the pesticides on the vegetable squash will be more.
Secondly, because the vegetable gang is close to the ground, the chances of reducing or breaking down the pesticides caused by the sun and the sun during the day and night are relatively small, so the pesticide residues on the vegetable rags are even more stubborn. However, there are no such problems as vegetables such as stalks of stalks, vegetables, and other vegetables that do not have obvious vegetable gangs.
The green pepper, though hung, still follows this rule. Experts explained that because the green pepper plants are relatively short, spraying pesticides is often top-down, accumulating many pesticides in the pedicles of green peppers. Therefore, irrelevant vegetables such as green peppers have this trouble, and other cowpeas and cucumbers do not have such concerns.
Therefore, when we are eating vegetables, it is best to cut off the vegetables near the ground. The green pepper such vegetables, you should eat pipa off.
How to eat vegetables and fruits?
Tips
Buy fruits and vegetables and don't worry
Many consumers are surprised to see this one - it's fresh to eat vegetables, and it's not so delicious to eat after a few days. However, in order to maintain the "safety interval" of this criterion, consumers may wish to stay in mind, and more to create a few days of "safe period" for the vegetables that are bought back.
Experts reminded that in autumn and winter when the temperature is low and vegetables are not easy to rot, consumers may buy vegetables and fruits and put them in the natural circulation for a few days, especially green vegetables such as cabbage, Chinese cabbage and leek. It can speed up the natural decomposition of residual pesticides, especially in the cold winter, and many vegetables can not be spoiled after being put on the outside for a few days. You can use this method more frequently. In seasons with high temperatures, if you are worried about decay, you can keep it in a refrigerator with a large space for a few days. If you keep the internal air circulation, you can also help the residual pesticides evaporate.
Tips
Don't be fooled by "worm-eyed" vegetables
In order to eat vegetables without pesticide residues, many consumers like to buy green leafy vegetables and kidney beans with insect eyes. They think that such vegetables must not be pesticides.
He Jiguo suggested that don't be eager to buy fruits and vegetables with insect eyes, and there are no insect eyes to measure whether pesticides are used or not. Because consumers have bought worm-eaten fruits and vegetables, they have basically found no insects in the dish, and the vegetable growers do not catch insects artificially. Therefore, insecticides are generally removed after the occurrence of insect pests.
He pointed out that fruits and vegetables with insect eyes are killed by pesticides. Adults are killed by worm-free eyes. It is also important to note that adult insects are clearly more resistant than larvae, so the use of pesticides may be higher. In addition, the emergence time of the adult is definitely later than that of the larvae. Therefore, the vegetable application time of the insect eye is closer to the harvest, but the pesticide is less decomposed and the residue is high. In summary, consumers should not believe in the traditional concept that there is no pesticide in the eyes of insects.
