Choose leek to remove the root half an inch of the root pesticide at most soak in light salt water first

Spring is a good time to eat leeks. Chinese chives are fragrant and spicy, rich in nutrients and have certain medicinal effects. The sulfides in leeks have more effects such as reducing blood lipids, increasing appetite, dehumidifying and regulating blood. Recent tests have found that leek is a vegetable with relatively high organophosphorus pesticide residues, a large number of this pesticide into the human body will cause neurological disorders, poisoning will appear hyperhidrosis, language disorders and other symptoms. Generally speaking, the root of leek is the place with the most pesticide residues. The pest "leek maggot", which brings fatal harm to leek, lives underground and specially bites the root of leek, which will make the root of leek rot, break and cannot grow. The general spraying pesticide is ineffective to this pest. The pesticide must be applied underground and poured into the root of the leek in order to effectively remove the leek maggot. Even so, as long as you master the scientific identification method, you can rest assured to eat leek. Here are some good ideas for readers. First of all, be sure to cut off the root at least half an inch when eating. Second, choose leeks to "observe the color": first, look at the color, don't pick the one that looks particularly greenish; second, look at the head, don't pick the particularly stout one; and third, look at the leaves, don't pick the particularly thick one. Third, buy leeks that have been inspected by the relevant departments. Finally, try to soak the leeks in light salt water for more than half a day before eating them. Because the pesticides currently used are organophosphorus, which can be soluble in water, after buying leeks, they are soaked in water and washed with water, which can reduce the pesticide residues.
