Empty cabbage, also known as wèng, canteens, which are soaked, fragrance, are the seasoned vegetables。
However, such a non-favourable dish has been shaken by a large number of people who are afraid to eat it at all because they have heard that the hollow cabbage is the “vegetative poison king”。
How did the hollow cabbage become the vegetable poison king? Is that true

What's an empty cabbage
That's the truth
There are rumours that hollow cabbage is growing fast and that it has a strong capacity to absorb heavy metals, and therefore has very high levels of heavy metals in the body. Moreover, since emptied cabbage is grown in the summer, the pests are more severe at this time, and vegetable farmers are constantly required to perform pesticides, resulting in very high pesticide residues of emptied cabbage. The combination of these two factors leads to the name of the vegetable poison king。
But if we look at it carefully, we find that this statement is “defensible”。
First, there are many types of heavy metals, and hollow cabbage does have a better concentration for some, but not all! For example, with regard to cadmium, barley is better than cabbage, and shouldn't it be “toxic” if it's the logic of legend
Furthermore, the results of the guangzhou institute of agricultural sciences have confirmed that the four heavy metals in hollow cabbage, such as lead, cadmium, total mercury and arsenic, do not exceed national limits. "high metal content" is a concern that you can put down。
As for agricultural residues, it is true that the amount of pesticides sprayed in the summer is slightly higher than in winter. However, this is a time when sunlight is more abundant than winter, uvs are stronger and pesticides volatilize faster, and this addition does not provide a strong indication of the large residues of empty cabbage pesticides growing at this time。
In addition, there are those who say that the hollow cabbage is “toxic” and that it is grown in sewage. I can't believe it! At present, we are eating emptied cabbage, which is largely planted on land or in large sheds, with little production of aquatic emptied cabbage, which is more water-intensive and too dirty to grow。
It's no longer difficult for an old man to enjoy it
In any case, emptiness is not the "vegetative poison king" and let's stop eating emptiness for this nonsense. Moreover, hollow cabbage is of high nutritional value and is a treasured vegetable that cannot be missed
Summer food
It's good to be nutritious
Empty cabbage has the following nutritional advantages:
High calcium - the calcium content of hollow cabbage can be 115 mg/100g, which is higher in quantity alone than milk. It is also rich in vitamin k and magnesium, which can be used to replenish calcium, and it is good for strong bones。
Potassium - potassium content per 100 grams of hollow cabbage can reach 380 mg. Potassium plays an important role in stabilizing blood pressure, maintaining normal myocardial function and ensuring neuromuscular excitement. During the summer, heavy sweat and loss of potassium elements required timely replenishment。
High-smoking acids, which stimulate insulin releases insulin, assist in maintaining blood sugar stability。
High-eat fibres - the total dietary fibre content of emptied cabbage is 4g/100g, and the crude fibre content is twice as high as the celery trachea, with a strong abdomen。
And there's plenty of proteins, folic acid, vitamin a, vitamin c in the emptiness of the cabbage. It's good to eat nutrients, strong bodies, and green oil looks good
So, what should i do with the cabbage
Remember three
Pick out a good dish
The greener the leaves
Empty cabbage should be yellow-free, non-fat-free and usually greenier。
Two incisions, no decomposition
Observation cuts, if they are dry and lack water, indicate that they have been taken longer and may not be fresh; if they have changed colour and even decay, they are not recommended for purchase。
It's a three-student problem
The colour of the infarction is green, and the delicate tastes are soft; the infarction colours are white, and the incorrupture tastes hard and thinner。

I don't want to get black when i'm out
Remember to do that
The polyphenols contained in the hollow cabbage are oxidized, so they will soon become darker when they are fired. Although the impact on health is modest, it seems to have somewhat affected appetite。
If you want to keep your cabbage green and dark, try the following three little tricks:
1. After washing, immersed in water with white vinegar or lemonade for a few minutes
2. Distinguishing leaves and vegetables to ensure that they mature more evenly when they are made
3. A little wine or white wine is added to the fire。
Finally, let us remind you that no matter how much you eat, one step must be taken — water. Because of the high levels of herbal acid in hollow cabbage, the human intake of too much herbolic acid affects calcium absorption. In addition, as mentioned above, draught can make empty cabbage less hairy and more colourful。
