CCTV has revealed that there are some problems such as irregular use of high toxic pesticides and blind areas in a vegetable producing area in Guangzhou. The ladies in the circle of friends suddenly did not calm down.
In fact, everyone is very bad news but "talk about pesticide always on tenterhooks," color is not. Xiaobian thinks that even if our ordinary consumers can't participate in drug use and supervision, what can we do to buy vegetables that we can buy?
Pesticide residues are mainly organophosphorus and classes
There are more kinds of pesticide residues. Among the high toxic pesticides, organic phosphorus, heavy metal (mercury, arsenic preparations) and organic chlorine are the most.
The most common manifestations of organophosphorus pesticides after eating are the symptoms of dizziness headache, nausea and vomiting, flow of mouth water, sweating, blurred vision, weakness of visual substance and purple lips.
The remaining pesticide residue, which has no direct performance after eating, will indirectly cause heavy metal poisoning, such as mercury poisoning and arsenic poisoning, and the excess metal in children can also cause hyperactivity.
Sense judgment is not reliable, first of all kinds of attention
Jiao Dongyue said that at present, most of the agricultural products are used in the growth process, the naked eye is difficult to identify pesticide residues, or should be confirmed by testing. We can only make a judgment based on the growth cycle of agricultural products and the number of pesticide residues and the pesticide residue cycle. We can preliminarily summarize some kinds of fruits and vegetables with the most and least residue:
14 kinds of pesticide residues: apple, leek (organophosphorus residue), watermelon (organophosphorus residue), celery, strawberry, peach, spinach, imported nectarine, imported grapes, lantern pepper, potato, domestic blueberry, lettuce, Brassica.
The least 15 kinds of fruits and vegetables: onion, sweet corn, pineapple, avocado, asparagus, sweet pea, mango, eggplant, beauty, bizarre fruit, cabbage, sweet potato, sweet potato, grapefruit, mushroom and so on.
However, when we buy fruits and vegetables, we can smell it. Some organophosphorus pesticides have special odor or fragrance of garlic. It is easier to identify them. Or with hand touch, some powder fungicides have powder residue on agricultural products, and a little preliminary judgment can be made.
Peeling, blanching, basking in the sun, "discrimination" in addition to pesticide residues
It is important to emphasize that although there may be problems with fruit and vegetable residues, global nutrition experts have reached a consensus that fruits and vegetables are more beneficial to health than the harm of agricultural residues. If you eat correctly, you can reduce the harm.
Many people think that, with salt water or detergent solution cleaning can reduce the level of pesticide residues in fruits and vegetables, so to that extent. However, Jiao Dong was not fully approved of this kind of statement.
"Because of the different kinds of pesticides, it is not the best way to clean them with water or wash them with edible alkali or detergent. We must adopt different methods according to the different kinds of fruits and vegetables. " She summed up the following points:
1 leafy vegetables: soak in salt water or soda water to remove vegetables or vegetables.
2 peel fruits and vegetables: best peeled and then eaten, such as cucumber, apple, pear, peach and so on.
3 high temperature heating: beans, broccoli, celery and other vegetables like, with boiling water boiled, reduce the residue.
4 sunlight exposure: sunlight can cause some pesticides in vegetables to be broken down and destroyed. According to the determination of vegetables in the sun for 5 minutes, the residues of organic chlorine, organic pesticides can be reduced by about 60%.
5 soaking in rice water: rice water is a common "good recipe" in life. It is weak alkaline, it is weak alkaline, can neutralize pesticide components, weaken its efficacy, and also contain starch, with strong adhesion ability. So, wash the vegetables with rice water, soaking, simple and easy implementation, but also to the pesticide effect.
In addition, green and organic fruits and vegetables can be purchased, especially green leafy vegetables.
