Eat into the stomach "artificial pigment"

[EP Environmental Protection Network Comprehensive Report] Will there be a feeling that more and more things are "colorful" now, food looks bright and drops, lipstick cosmetics and so on are also colorful, but sometimes gorgeous "colors" are not all safe, especially those extracted from chemical raw materials, and those artificially added colors have a unified name-artificial pigments. Today, the small editor of EP environmental protection network will know this colorful "artificial" world.

Many artificial pigments extracted from coal tar will pollute water resources

Synthetic pigment refers to the organic pigment made by artificial chemical synthesis method, which is mainly made from aniline dye separated from coal tar. Synthetic colorants can be classified into azo, oxyanthracene and diphenylmethane. National health standards included in the use of artificial pigment for the following 8 kinds: carmine, amaranth, sunset yellow, erythrosine, lemon yellow, new red, indigo, bright blue.

Artificial pigments are widely used in food, chemical industry and daily chemical products. People often eat these artificial pigments into their stomachs and put them on their bodies.

Artificial pigments are relatively safe to use within the prescribed standards, but azo and oxyanthracene artificial pigments will produce contaminated wastewater during dyeing and washing, and the treatment of these wastewater is very difficult. Because they are artificial compounds and lack "natural enemies" in nature, it is tedious and difficult to crack their molecules. Although some experts have suggested that microorganisms can be used to treat contaminated wastewater, however, because the role of microorganisms is not yet efficient and lasting, it is only in the research stage.

Artificial pigments have a huge impact on the human body and are carcinogenic.

In recent years, in the process of using synthetic pigments as additives, many synthetic pigments have been found to be harmful to the human body. For example, butter yellow, which was used for coloring margarine in the past, has long been confirmed to cause liver cancer in humans and animals, while other types of synthetic pigments such as orange yellow can cause skin sarcoma, liver cancer, bowel cancer and malignant lymphoma. Research results published in the Journal of Surgical Medicine in recent years have shown that artificial pigments may cause behavioral changes in children. "ADHD in children" and excessive behavior in children are related to long-term consumption of foods containing synthetic pigments.

The former Soviet Union conducted long-term animal tests on amaranth, an edible pigment, in 1968-1970, and found that the carcinogenic rate was as high as 22%. Researchers in the United States, Britain and other countries have also found that not only amaranth, but also many other synthetic pigments are harmful to the human body, which may lead to diarrhea, decreased fertility, teratogenesis, and so on. Some pigments may be converted into carcinogens in the human body.

In addition, carmine and Sudan Ⅰ, which is banned by EU standards, belong to azo pigments. Azo compounds can be metabolized in vivo to form mutagenic precursors --- aromatic amines. After aromatic amines are further metabolized and activated, they become electrophilic products, which can combine with DNA and RNA to form adducts to induce mutations. It can also be oxidized to produce free radicals, which in turn produce a series of reactive oxygen species (ROS) with metabolism in vivo, the latter can cause DNA oxidative damage, resulting in genetic lesions.

Artificial food coloring itself has no nutritional value. The only value is to make the food look more "fresh and delicious". Chinese people have always paid attention to "color, flavor and taste". Although it is difficult to abandon this habit for thousands of years in a short period of time, it is necessary to pay attention to it. What it brings is not only for the consideration of one's own generation, but also a choice for the benefit of future generations. (Summer rain)
