Eating more vegetables can also reduce the pressure. "Clinical Nutrition" was a research conducted by the University of Edisco, Australia.

Two, 4 kinds of vegetables contain formaldehyde?Today, make it clear
The vegetables must be eaten appropriately, so whats the matter of formaldehyde vegetables?In recent years, there have been many rumors about vegetables. Among them, formaldehyde vegetables are the most circulating, and many people even dare not eat vegetables.Today, Xiaojiu explained these rumors.
1. The tape that bundles vegetables is formaldehyde, which will contaminate vegetables?
It is rumored that the tape adhesive component bundled with vegetables in the supermarket is formaldehyde, which will affect health after eating this vegetable.
In fact, relevant standards in my country have strict standards for all packaging materials that contact foods. Most of the tape bundled vegetables are polymer materials.

2. The beautiful carrot in the outside is actually used for formaldehyde?

Professor Liu Shaowei, a member of the expert group of the Shanghai Food Safety Research Association, said that cleaning carrots in the supermarket are the result of strict food treatment process.The reason why bloggers on online evaluations will measure the excess of formaldehyde because they use air formaldehyde kits, but they do not simulate the real scene of life.In addition, the phenol test contained in the kit itself will react with the formaldehyde in the air and the aldehydes, phenol, and aromators in the radish, and make the reagent blue.
This experiment itself is not rigorous and scientific. As long as it is a carrot purchased from regular places, there is no need to worry about the problem of formaldehyde excessive standards.
3. The formaldehyde content is higher in mushrooms?
It is rumored that the mushrooms purchased by the supermarket are still fresh after more than ten days, and the measuring found that the formaldehyde content is severe exceeding the standard, reaching the level of severe pollution.
Liu Chang, director and chief physician of Zhengzhou Central Hospital affiliated to Zhengzhou University, said that the method of measurement is unscientific in itself.After the enzyme is metabolized, the edible mushrooms will indeed produce trace formaldehyde, but it will almost volatile after cleaning and cooking, which will not affect health.

Earlier news reports that some merchants will immerse them in formaldehyde in order to keep dolls in formaldehyde. Frequent consumption will cause physical poisoning and affect health.
The states explicit order is prohibited from adding formaldehyde in vegetables, and you can purchase vegetables in regular places daily.Even if formaldehyde is detected in vegetables, most of them are their own metabolic products, far lower than the national limited standards that will not threaten health.
