Is the 'King of Poison', heavy metal exceeds the standard? Is it harmful to the human body and carcinogen? Here comes the truth

"Do not eat spinning vegetables, because spacious vegetables are the most powerful type of pesticides and heavy metals in all green leafy vegetables. It is the king of poison . Very serious vegetable land ... "

Aunt Li watched the "popular science" video he brushed, and the whole person was stunned, and he felt uncomfortable in an instant.

Because of all the green leafy vegetables, she likes to eat spoils the most. When I went to walk in the morning, she also bought a piece of waterful vegetables and prepared to make dinner.

Aunt Li forwarded the video to the good sisters who also love to eat spinach. Both of them were very disturbed. If this is the case, will the heavy metals in their bodies be severely loaded?

First, the spinning vegetables are "King of Poison"? Many people are still in the drum

Ventorcus, formerly known as Yongcai, served cabbage and inadvertent cabbage are its "nicknames", which is more common in southern China. Is its "crime" real?

There are indeed some studies that spoils have strong enrichment capabilities for some heavy metals such as lead, but this does not mean that it is the case for all heavy metals.

There are many heavy metals in the environment, and the adsorption capacity of other heavy metals should be slightly inferior to other heavy metals. For example, in Guangzhou, research has found that the ability of cadmium to enrich cadmium is stronger than spoil .

Take a step back, even if it contains heavy metals in leafy vegetables, there is a safe range . According to the national standard GB2762-2017 "Limits of Pollutants in Food Safety National Standard Food", leafy vegetables are stipulated, lead <0.3mg/kg, cadmium <0.2mg/kg, total mercury <0.01mg/kg, total arsenic <0.5mg <0.5mg /Kg.

Therefore, as long as the heavy metal content in the spinach does not exceed these standards, it will not threaten human health.

In addition, the content of heavy metals is high or low, and the origin environment is critical . If the ecological environment, such as soil, water, there is no problem of heavy metal exceeding the standard, the planting of the grown can naturally be eaten with peace of mind.

As for the "vegetable land with very serious pollution in the suburbs of the spinning vegetables" circulating on the Internet, it is also nonsense, because the spoils are relatively high in planting conditions. At present, the purchased on the market is basically land planting or greenhouse planting .

Therefore, as long as you can buy it from the regular vegetable market and supermarket, you can eat it with peace of mind.

Second, the spinning vegetables are "gloss dishes"?

Many people say that after eating spoil, they will have leg cramps when they sleep at night, so the spinning vegetables are also called "cramps". Will eating empty cabbage really cause cramps?

In this regard, the chief physician of Liang Donghui, the Department of Traditional Chinese Medicine of the Pearl River Hospital of Southern Medical University, said that the reason why many people think that eating empty cabbage will cramp because it contains oxide, which can affect the absorption of calcium in the human body, and the calcium ions in the blood in the blood in the blood are of them. When lacking, it is easy to cramp.

In fact, calcium in blood is very stable.

Once fluctuations appear, calcium ions are reduced, and the calcium in the bones will extend "help" and make up for it in time . Therefore, there will be no situation of too little calcium ions, and then there will be no cramps. You can eat empty cabbage with peace of mind.

Before eating spinning, there is another very important link, that is, selecting. So how do I choose a good ethereal vegetable?

• Choose a green color, no yellow leaves or damaged;
• The selected incision is not rotten or discolored;
• The stem selection is relatively thin and the taste is tender.

As long as you master the above 3 selection skills, you can have fresh spinning!

Third, the three kinds of vegetables that are often eaten are "formaldehyde", which is toxic and carcinogenic?

Regarding "formaldehyde vegetables", there are many vegetables in life "unjust". Everyone must learn to distinguish rumors and don't wrong these vegetables.

1. Vegetables bundled with tape

The tape does belong to the gray zone, but the Shenzhen Municipal Inspection Institute had previously tested 11 vegetables and tape samples without detecting formaldehyde, so you don't need to worry too much.

2. White tofu

The color of tofu is mainly related to factors such as raw materials and coagulants. It does not necessarily add formaldehyde, so you must not rely on the color to determine whether the food contains formaldehyde.

3. Chinese cabbage

Because the taste is pungent, inhalation may damage the respiratory tract, but if it is used as a food, it is another matter when entering the digestive tract, because formaldehyde is easily soluble in water and volatilizes , and it will be swinged during transportation. Coupled with cooking, the content is almost existed, which is not enough to pose a threat to the human body.

It should be emphasized that adding formaldehyde is illegal. Once found, it is responsible for the law. However, the situation of the practical formaldehyde soaked vegetables in life is still relatively rare, because formaldehyde contains irritating odors. If it is used, it is easy to be smelled by the nose at once .

In addition, some natural foods also contain formaldehyde, including fruits and vegetables, meat, fish, dry bacteria , etc.

Therefore, do not prejudice everything about formaldehyde. Its harm is mainly inhalation. There is no serious harm to formaldehyde intake through food.

However, from security considerations, it is recommended that you buy ingredients from regular, large supermarkets and other places . It should be completely heated before cooking. Because formaldehyde is a high temperature and volatile substance, which can help us remove the possible residual formaldehyde to reduce risks.

Extension -teach you 3 wonderful tricks to remove pesticide residues, rest assured to eat food

Regarding the safety of vegetables, many people are more worried about the problem of pesticide residues. How should they remove pesticide residues? Teach you 3 tricks.

• ventilation

Do not lose the refrigerator directly from the fruits and vegetables that you just purchased from the store. It is best to put poison in a ventilated and dry place, which helps the volatilization of pesticides and reduce the amount of pesticide residues.

• Peel

For example, cucumber, radish, bitter gourd, etc., can peel all the peel, because pesticide residues are basically on the epidermis, so remove the skin to maximize pesticide residues.

• Boiled water

For example, the more difficult fruits and vegetables such as cauliflower, cowpea, lentils, etc. can be treated with water, and some pesticides can be volatilized and decomposed.

Summary: Regarding the safety of vegetables, there are many true and false statements circulating on the Internet. Everyone must learn to distinguish. After buying vegetables, the treatment of ingredients is also important. Try to handle it in place to reduce food safety risks.
