Ms. Li, a 48-year-old high school teacher, pays great attention to eating a healthy diet and buys a lot of fresh vegetables every day.
Recently, she saw a message on the Internet: "Several vegetables have 'formaldehyde' hidden in them. This news made Ms. Li wonder, which vegetables contain formaldehyde, and whether it is harmful to health, so she decided to go to the hospital for consultation.
Ms. Li went to a tertiary hospital in the city and found Dr. Wang from the nutrition department.
Ms. Li asked, "Dr. Wang, there has been news on the Internet recently that some vegetables contain formaldehyde and cannot even be washed off, is this true?
Dr. Wang smiled and patiently explained, "Mr. Li, the news you heard is actually a misreading.
Many vegetables, such as spinach, celery, chrysanthemum, etc., do contain a substance called methylenetetrahydrofolate, which is a B vitamin that is beneficial to the human body.
They can be involved in DNA synthesis, prevent anemia and neural tube defects, etc. However, its chemical name contains the word 'formaldehyde', which may have caused some people to misunderstand and panic. "
Ms. Li thought thoughtfully: "So that's the case, I thought it was real formaldehyde." Is it high in this substance? Isn't it good to eat too much?"
Dr Wang explains, "This substance is found in very low amounts in vegetables, but on the contrary, it has many benefits for the body.
We don't have to worry at all, we should eat more fresh vegetables, preferably more than 500 grams a day, with meat and vegetables, and a variety of ways to eat, which is the healthiest way to eat. "
Ms. Li breathed a sigh of relief: "Then I'll be relieved." I was worried that I wouldn't be able to wash it, but I was too worried. "
Dr. Wang adds, "However, during the planting and transportation of vegetables, there may be harmful substances such as pesticides, heavy metals, parasite eggs and other harmful substances on the surface.
Therefore, before cooking, it is still necessary to rinse repeatedly with clean water, and it is best to soak it in rice washing water or salt water for a while to remove these harmful substances. "
Ms. Li nodded again and again: "Dr. Wang said it really well. I will pay attention to these details when buying and washing vegetables in the future. "
In many people's impressions, "formaldehyde" is a toxic and harmful substance, and it is inevitable to panic when they hear that vegetables contain formaldehyde.
But in fact, although the name of "methylenetetrahydrofolate" in vegetables contains the word "formaldehyde", it is a B vitamin that is beneficial to the human body.
A number of studies have shown that moderate intake of methylenetetrahydrofolate can prevent anemia, neural tube defects, cognitive dysfunction, etc., especially pregnant women, who need to supplement this nutrient to prevent fetal malformations.
The low levels of methylenetetrahydrofolate in vegetables are far from sufficient to cause toxic effects, but can have great health benefits.
Of course, vegetables may have pesticide residues during the planting process, and dust, heavy metals, parasite eggs, etc. may also be contaminated during transportation. Therefore, before eating, it should be rinsed repeatedly with clean water to remove these harmful substances.
To sum up, the statement of "formaldehyde" in vegetables is a pure misreading, in fact, it is a beneficial B vitamin, which is not only harmless, but has many health benefits.
We don't need to panic, we should scientifically understand that eating more fresh vegetables every day, with a balanced mix, and at the same time pay attention to cleaning methods, remove pesticide residues, pollution and other harmful substances, we can greatly improve the level of health.
