Leek is deeply loved by people because of its unique fragrance and good health care function, especially in strengthening yang and benefiting qi. However, in the vegetable market, we must pay attention to this kind of leek. Eating it will make people poisoned and even cause cancer. Let's take a look at it with 5 1 Health Network.

This kind of poisonous leek is difficult to distinguish under external light, but it is not indistinguishable. If you see those dark green leaves, they may be poisonous leeks. This kind of leek is generally a kind of leek that is "root-irrigated" with highly toxic pesticides. In order to control the pests at the root of leek, it can make leek grow well and sell at a good price.

In fact, the really healthy leek is not so good in appearance, and even a little "malnourished". So how to choose a good healthy leek?

1, don't choose the one that looks very green and black.

2, don't choose a particularly thick head, just like the kind with hormones.

3. Don't choose thick leaves.

If you don't choose these, you can try to avoid buying poisonous leeks with pesticides. Of course, when buying leeks, remember to soak more and rinse more to minimize the residue of pesticides on them. Another point is that leeks should be cooked as much as possible to reduce the harm of pesticides to the body.
