The Spring Festival is approaching, and I believe that many people are busy preparing for the New Year, among which vegetables are indispensable. At this time, in order to cater to the needs of consumers, some businesses will list all kinds of vegetables, which is dazzling.
But there are some vegetables that the vegetable sellers never eat, but some people rush to buy them, why? It turns out that these vegetables may have many problems, not only affect the taste, but also may cause harm to the body.
Let's take a look at the 4 best vegetables not to buy before and after the Spring Festival, everyone must know.
1. Hard tomatoes
Tomatoes are basically sold all year round, and many people like to eat tomatoes because they are rich in vitamin C and lycopene, which are good for beauty and beauty.
Most of the tomatoes on the market are cultivated in greenhouses, which can ensure the yield and quality.
But in order to increase sales, many tomatoes are picked when they are not ripe and then used to make them red with ripening agents.
These ripening agents may contain chemicals such as ethylene, ethephon, ethylene, etc., which may cause damage to the liver and nervous system when consumed for a long time.
The performance of ripening tomatoes also includes: hollow, deformed appearance, red on the outside and green on the inside, etc., and everyone must have the ability to distinguish them.
In particular, tomatoes that are very firm when pinched, most likely unripe tomatoes, have been sprayed with ripening agents, so it is recommended not to buy them.
Second, hit the hormone cucumber
Many people think that cucumbers with thorns on the top flowers are fresher, but this is not entirely true.
It is important to know that cucumber transportation takes a certain amount of time, from the field to the vegetable market, and then to the hands of consumers, at least one day.
By the time it is transported to the vegetable sellers, the top flowers have long been wilted, and it is impossible to keep them alive. So, why do some cucumbers still maintain their top flowers?
This is because some cucumbers have been hormonized to make them look fresher. Moreover, the cucumber with hormones is often raised at the junction between the top and the top flower, which is a trace of hormones.
3. Out-of-season leeks
We all know that leeks are generally a seasonal vegetable in spring, and it is highly nutritious and helps to boost immunity and digestion.
But in winter, leeks are difficult to grow because it needs plenty of sunlight and temperature. If you see leeks on the market, most of them are grown in greenhouses.
There is nothing to grow in greenhouses, mainly because the leeks purchased in winter are usually very stout, like this leek may be sprinkled with some pesticides or hormones to make the leeks so thick.
Such leeks not only have reduced nutritional value, but also may leave some harmful substances, which is not good for the human body.
Fourth, seal the Chinese cabbage
Chinese cabbage is a common dish in many households, it is cheap, has a refreshing taste, and can be used to make many dishes.
But Chinese cabbage is also very spoiled, especially during the Spring Festival, and many people will stock up in advance for emergencies.
And some businesses, in order to keep the cabbage for a longer time, may spray a small amount of formaldehyde on it, and then seal it with plastic wrap, so that it can be stored for a longer time.
In addition, some Chinese cabbage may have rotted inside, but because it is sealed, it cannot be seen, and it can only be found when it is peeled off, so such cabbage cannot be eaten.
