Xiao Wang works hard in a big city and rarely sees his mother, so he taught his mother to use a smartphone when he is free, and it is easier to contact.
But since his mother is proficient in using her mobile phone, Xiao Wang always receives various forwarded messages from her mother from time to time, and recently she has been dominated by "formaldehyde dishes".
"In order to keep the vegetables fresh, black-hearted merchants abuse formaldehyde, and this dish can't be eaten!"
"Why does formaldehyde vegetables enter the market? I advise you to throw it away as soon as possible! ”
Among the protagonists of these articles, there are contaminated spinach, and some say that Chinese cabbage or cabbage are indignant unscrupulous merchants illegally use formaldehyde water to soak vegetables, resulting in excessive formaldehyde in vegetables, and formaldehyde is a class of carcinogens, and eating formaldehyde vegetables will attract cancer!
Xiao Wang was very puzzled, he had only heard of formaldehyde pollution at home, and vegetables also had formaldehyde?
Formaldehyde is a colorless and pungent odor gas, if people are exposed to formaldehyde concentration for a long time, it will not only damage the skin and respiratory tract, but also may cause cancer, leukemia, etc., the World Health Organization's International Agency for Research on Cancer has long included formaldehydeClass 1 carcinogens.
Formaldehyde in daily life mainly comes from indoor decoration materials, furniture and other pollution, why is there formaldehyde in vegetables?
Formaldehyde in vegetables is mainly divided into endogenous and exogenous.
Endogenous formaldehyde is naturally produced during the metabolism of vegetables, such as fruits, fish, meat, vegetables, etc., all contain endogenous formaldehyde, but the content is very small, and it is not harmful to health.
whereasExogenous formaldehyde is mainly used in the process of food processing, transportation and sales, which is also a cause of formaldehyde contamination in food.
Previously, the formaldehyde Chinese cabbage circulating on the Internet was illegally added with exogenous formaldehyde, and the merchant said that the purpose was to prevent preservation and prolong the storage time of Chinese cabbage.
Regarding the rumor of "formaldehyde vegetables" that has been circulating on the Internet for a long time,Ruan Guangfeng, Kexin Food and Health Information Exchange CenterThe publication stated: "This is only a trumped-up charge. First of all, our country isThe use of industrial formaldehyde in food processing is expressly prohibitedIf the merchant illegally uses formaldehyde, it shall be punished by law;
Formaldehyde smells great, and it is easy to be found after use, and nowFood processing technology continues to advance, and there are many methods of antiseptic bleaching, so there is no need for businesses to take risks；
Even if a small amount of formaldehyde is really added to vegetables, there is no need to panic excessively, becauseFormaldehyde is volatile and will volatilize into the air during transportation, storage, cleaning, and cooking, with a very low residue。 ”
As long as you buy vegetables from regular channels, you can eat them with confidence. If you are worried about formaldehyde residues, then soak the vegetables in water, wash them several times, and cook them thoroughly, and there is no big problem.
Chinese cabbage is inexpensive and durable, and in the north, Chinese cabbage is stocked up in winter. However, there are rumors on the Internet that people with high blood pressure can't eat Chinese cabbage, is this true?
Traditional Chinese medicine believes that cabbage is sweet and non-toxic, and it has the effects of cough and phlegm, heat clearing and detoxification, widening the chest and removing annoyance, and benefiting the stomach and intestines. Modern medicine has found that Chinese cabbage is rich in potassium, calcium, iron, vitamin C, vitamin E and other nutrients, rich in dietary fiber, but very low in calories, and eating Chinese cabbage regularly will bring the following multiple benefits.
1. Enhance immunity
Every 5g of Chinese cabbage contains 0.0mmg of vitamin C, which is higher than lemons, oranges and other citrus fruits, and vitamin C can enhance the body's immunity, thereby better preventing colds and other diseases.
2. Laxative
Chinese cabbage is rich in dietary fiber, which can promote intestinal peristalsis and improve constipation. Chinese cabbage has a water content of up to 95%, eating more Chinese cabbage in winter can replenish water and prevent heating diseases, and at the same time, Chinese cabbage has low fat content, and the pectin contained in it can adsorb cholesterol and help reduce blood lipid levels, which is suitable for people with fat loss.
3. Protect the cardiovascular system
Chinese cabbage has a higher potassium content, as high as 10mmg/0g, which is even 0 times higher than bananas. Potassium can promote sodium excretion, reduce blood vessel pressure by inhibiting the renin-angiotensin system, stabilize blood pressure, protect blood vessel walls, reduce heart burden, and protect heart health.
So,Patients with high blood pressure are still very suitable for eating Chinese cabbage, and what patients with high blood pressure really want to eat less is actually these two dishes:
High Calcium Vegetables:Vegetables with a sodium content of more than 100mmg per 0g of vegetables are considered high-sodium vegetables, such as:fennelSodium content: 100.0mmg/0g,Milk cabbageSodium content: 100.0mmg/0g,Kraft greensSodium content: 100mmg/0g,
ArtemisiaSodium content 100mmg/0g. These are high-sodium vegetables, and patients with high blood pressure should eat less, otherwise sodium will increase vascular resistance and increase blood pressure.
Pickled vegetables:Pickles use a lot of salt, and long-term consumption will increase the risk of high blood pressure, which is not conducive to blood pressure control in patients with high blood pressure. Also pay attention to nitrite in pickled vegetables, nitrite can also be converted into carcinogens nitrosamines when it enters the stomach, increasing the risk of cancer.
冬季來臨，“百菜之王”的白菜上線，很多餐館和家庭都會屯它。不過，大家在選購白菜時可要留心了，所謂“白菜四不吃，吃了冬難安”，以下四不吃，你又知道幾個呢？
1. Overnight cabbage
In winter, when the room temperature is low, overnight ripe cabbage will be contaminated by bacteria and spoiled, but because the smell and color of spoiled cooked cabbage will be masked by seasoning, the best thing to do is not to eat overnight cabbage.
2. Dried cabbage
Cabbage leaves are the most abundant in water and nutrients, but if they are not stored properly, cabbage will lose a lot of water, which will not only fail to absorb after eating, but even affect gastrointestinal peristalsis. In particular, the dryness caused by non-exposure to the sun is likely to be caused by mildew, and this kind of dried cabbage is even more inedible.
3. Rotten cabbage
Even if the core of the rotten cabbage is okay in appearance, do not eat it, because spoilage means that there are a large number of spoilage bacteria breeding, which not only has a poor taste and low nutritional value, but also is easy to damage health after eating.
4. Cabbage with black spots
If the cabbage leaves are black spots caused by the larvae of the cabbage moth and the leaves are not rotten, then the cabbage can be eaten after washing off the black spots and cooking.
If the black spots on the cabbage are about 2-0mm in diameter and cannot be washed away by water, it is most likely a small black spot disease, which is related to improper storage or too much nitrogen fertilizer.
IfThe diameter of the small black dot is more than 2mm, and the black dot turns yellow or begins to ooze, this cabbage may have spoiled, so you have to don't eat it.
Winter is coming, many families will begin to stock up on frost-resistant and good storage of Chinese cabbage, about the rumors of "formaldehyde vegetables", we don't have to worry, after all, the state has regulations prohibiting the use of formaldehyde, as long as you go to the regular place to buy vegetables, you don't have to worry about formaldehyde exceeding.
