Pigment is bad for health?

Synthetic pigments have many advantages, but these substances are not useful nutrients for our human body. Excessive use will show certain harm, namely toxicity (including toxicity, diarrhea and carcinogenicity). It can be said that as long as the pigment is used in a specified dose and within a specified range, its safety is guaranteed. Excessive abuse of pigment will endanger people's health. If people eat a large number of foods with excessive pigment content for a long time or at one time, especially foods containing pigments such as lemon yellow and sunset yellow, it may cause allergies, diarrhea and other symptoms; When the intake is too large and exceeds the body load, it will accumulate in the body, causing certain damage to the kidney and liver. The experimental results also show that a large number of synthetic pigments can cause allergies, such as asthma, laryngeal edema, rhinitis, urticaria, itchy skin, nervous headache and so on. Some synthetic pigments act on human nerves, which will affect the transmission of nerve impulses and lead to a series of symptoms. Therefore, people must be careful when eating colored food. It is understood that the use of synthetic pigments in the following foods is prohibited in China: meat and its processed products (including viscera processed products), fish and its processed products, fruits and their products (including fruit juice, preserved fruit, jam, jelly and brewed fruit wine), condiments (vinegar, curry powder, soy sauce and tofu), infant food (including milk powder and milk powder substitutes), biscuits and cakes (only on the color packaging of cakes) Five suggestions to remind consumers to distinguish "colored" food. There are always some unscrupulous vendors who add too much pigment in pursuit of profits. In order to reduce the harm of pigments to our health, in addition to strengthening management and cracking down by relevant competent departments, consumers should also pay more attention and try to choose products that do not use pigments or use a small amount. ● Colorants are used in food production and processing, and the specific name of the colorant used must be marked on the food label. Look carefully at the ingredient list on the food label and try to eat less food containing synthetic pigments. ● When two or more colorants are added to a food, the colorants should be marked, followed by brackets to indicate the specified colorant code. Colorant code can be inquired through GB2760. For example, the codes of foods with three colorants, turmeric, alluring red and brilliant blue, are 102, 0 12 and 007 respectively, which can be labeled as "colorants (102, 0 12, 007)". ● For foods that we can't tell whether there is too much pigment, consumers can choose those brand-name products. ● Food intake should be diversified. Food diversification is not only the guarantee of balanced nutrition, but also the guarantee of food safety. Because the pigments in food can only do harm to human body in a certain amount, we can reduce the intake of these foods containing pigments.
