ChenauntRecently, I haven't bothered to manage the water spinach planted on the balcony, and I've been worried all day.

It turns out that I recently swiped on the Internet and said that water spinach has a high content of heavy metals, and it may cause cancer if eaten often! oldauntI remembered that I ate it every day before, wasn't it in the middle of it?

I don't know if it's a psychological effect, I feel a little uncomfortable inexplicably, is it also caused by eating water spinach?

1. The "back-pot man" in the vegetable industry, heavy metals are still carcinogenic?

What is certain is thatLeafy vegetables are more susceptible to heavy metal contaminationAnd there are indeed studies that have found that water spinach has a slightly higher ability to absorb heavy metals.

But this does not mean that the heavy metal content of water spinach is necessarily high, water spinach as a fast-growing plant, it is easy to be affected by the surrounding soil environment, but as long as there is no heavy metal pollution in the soil environment, there will naturally be no excessive heavy metals, and the stem of water spinach is hollow, and the content of heavy metal pollution may be lower than that of other vegetables.

And according toGuangzhou Academy of Agricultural SciencesMeasuredThe heavy metal content of water spinach did not exceed the national food contamination standard。

Second, it is rumored on the Internet that 4 kinds of vegetables cannot be eaten and are blacklisted?

In recent years, more and more vegetables have been rumored to cause cancer, and some netizens have also compiled a vegetable blacklist, but do these vegetables really have so many risks?

1. Bracken

According to the survey, there was a high incidence of malignant tumors such as esophageal cancer and gastric cancer in the mountainous areas of central Japan at that time, and bracken accounted for a large proportion of the local diet, so it was suspected that bracken was a risk factor for cancer.

According to experts, the "carcinogenicity" of bracken actually comes from one of themProtoferniningredients. This ingredient reacts with amino acids in the human body to form dienones, which destroy genetic material such as DNA, causing cell abnormalities and eventually leading to cancer.

But you don't have to worry too much, because although bracken is rated as a class 20B carcinogen, it is not necessarily carcinogenic, and it depends on eating bracken to get cancer, and it may take at least a few catties of bracken to eat at least a few catties of bracken every day for 0 consecutive years to reach the carcinogenic amount. AndProtofern glycosides are easily soluble in water, and if they are blanched, the harmful substances will be destroyed。

2. Baby cabbage

Some people say that the preservation of baby cabbage is done by soaking formaldehyde water, and long-term eating will cause leukemia if you consume too much formaldehyde.

In fact, formaldehyde is expressly prohibited from being added to food, businesses illegally add formaldehyde will be punished by law, and formaldehyde smells very big, it is easy to smell, plus the cost of formaldehyde is not low, there is no need to take risks, even if there are really businesses to do this, you must know that formaldehyde is soluble in water, but also volatile, plus transportation, cleaning a series of processes to reach the table, the basic formaldehyde residue has been basically equal to none.

3. Folded ear root

It is rumored that Houttuynia cordata contains aristolochic acid, which is very toxic, and people can cause kidney damage and even cancer after eating it.

TrulyHouttuynia cordata contains aristolochia lactam, not aristolochic acid. Aristolochic acid has long been listed as a class 1 carcinogen by the International Agency for Research on Cancer, and it does have harm such as kidney toxicity, but this substance is not found in Houttuynia cordata.

Although in vitro experiments have found that Houttuynia cordata extract may be harmful to liver cells, it is not possible to prove whether it has the same effect in vivo experiments, and the safety evaluation method needs to be further evaluated.

So, Houttuynia cordataEat in moderationThere is definitely no problem, and normal people have a limited amount of consumption in a day, and they cannot reach the toxic dose.

4. Chayote

There is a saying that chayote will produce a kind of called when it is friedAcrylamidecarcinogens, so can not be eaten.

But in fact, acrylamide is not uncommon in everyday foods, such as fried foods, puffed foods, and foods that need to be cooked at high temperatures, which can be found not to be a problem with the food itself, but to be processed at high temperatures.

And even if chayote has the risk of carcinogenicity, just by eating chayote to achieve carcinogenic amount, at least eat a dozen catties of chayote at one time, and your stomach may not be stuffed if you don't eat carcinogenicity, soEat in moderation every day，Pay attention to the way you cookIt can also be eaten normally.

To sum up, let's talk about it seriously,It's not so much that vegetables cause cancer, it's better to say that "information is carcinogenic"!

Many people can't correctly distinguish the source and accuracy of information, leading to blind anxiety and breeding health risks, so paying attention to the source of information, whether it is officially certified, and actively seeking truth is the key.

3. What may really cause cancer are these "dishes"!

Although most of the carcinogenic vegetables on the Internet are fake, some "dishes" do have certain health risks and are not suitable for long-term consumption, such as these 3 common dishes:

1. Pickled dishes

There was a research team at Zhejiang UniversityBMC MedicineStudies have been published in journals that show that people who eat pickled vegetables for 4 days or more a week willIt increases the risk of death from 45% gastrointestinal cancer and 0% of esophageal cancer。

Because most of the preserved foods contain a large amount of nitrite, long-term intake of this substance can irritate the gastric mucosa and even increase the risk of cancer.

2. Dishes that are too hot

If the food is too burned, it can irritate the mucous membranes of the mouth and esophagus, and possiblyCauses chronic inflammatory reactions, increasing the risk of cancer.

3. Overnight dishes

It is also easy to produce in overnight dishesnitriteLong-term eating is also not good for health, and may even induce digestive tract cancer.

4. Stir-fry the vegetables after smoking

If you are also stir-frying and wait until the oil is hot and smoking, you may need to be careful, because this way cooking food willProduces some toxic carcinogens, especially dishes with high starch content, so it is recommended that it is safer to put vegetables in a cold oil state after heating the pan.

Generally speaking, the harmful eating habits of the human body are the source of toxic health, and we must pay attention to whether there are any of the above dietary preferences in our daily life, and if there are any, adjust them quickly to avoid unnecessary effects on our health.
