According to Voice of China’s “Yangguang News” report, Coke kills sperm and Coke leads to osteoporosis, Coke's pigments cause cancer, and the Coke that the people of the world love to drink has always been full of various legends. Coke in the end there are no side effects? Start with the latest "carcinogenic" rumors.

A few days ago a U.S. health agency said that Pepsi purchased in 10 U.S. states contains 4-methylimidazole, a chemical associated with rodent lung cancer tumors. This ingredient, which was first detected more than a year ago, was detected by four consumer groups in the United States: Coca-Cola, PepsiCo, Diet Coke and Pepsi Lights. More than a year later, last month, some environmental groups tested Pepsi and Coca-Cola again. The results showed that most of the Coca-Cola products tested had no caramel pigment, but the Pepsi tested still contained 4-methylimidazole.

What exactly is 4-methylimidazole? Cola's red tan comes from its added artificial color, caramel color. The by-product of caramel is 4-methylimidazole. The content of this ingredient in caramel is related to specific products, and the EU regulations cannot exceed 250 ppm. The concern about 4-methylimidazole "carcinogenesis" comes from a 2007 study. According to comparative preliminary animal experiments, high doses of 4-methylimidazole have carcinogenic effects on certain types of mice. The California State Environmental Health Hazard Assessment Office and the American Center for Public Interest Science took credit for the results and led directly to Coca-Cola's change of its formula. Center Chief Michael Jackson:

Michael Jackson: This is indeed a step in the right direction. I hope Coca-Cola and PepsiCo will promote the move nationwide and do so in other parts of the world. Coke’s sales are not less in those places than in the United States.

In fact, for the "carcinogenic" argument, more authoritative agencies including the US FDA do not agree. Analysts also believe that manufacturers including Coca-Cola change the formula of Coke products, not for scientific reasons, but only to meet the needs of the market.

Members of the Scientific Squirrel Association and senior member of the American Food Technology Association cloudlessly stated that the results of large-dose animal experiments with more uncertainties were used to estimate the effect of small doses on the human body, and the results were not sufficient.

Cloudless: Caramel is widely used in food, not only in Coke, it is approved as a food additive, but also has done more safety tests, both the US FDA and the Food Safety Agency believe that caramel There is no safety problem with pigments.

The US FDA commented on this, “I do not think that this substance can bring any direct danger to human health. Only when a person drinks more than 1,000 cans of Coke a day can it cause a similar cancer risk in the Science Center for Public Interest. ". Drink 1000 cans a day means that even if you do not eat or sleep, drink 1 can every minute, it will take 17 hours to finish drinking. Clouds said inadvertently that it is obviously not of any reference significance for ordinary people to drink Coke.

Cloudless: carbonated drinks such as cola are not a good beverage in itself, and have nothing to do with cancer, especially sugary cola, because of its high sugar content, which is detrimental to health, if the general sugar-free Coke also Yes, but it is, after all, an acidic beverage that does not have any value for health. However, after all, it has many people like it. I don't think that changing the way you drink or not coke is caused by the legendary cocaine cancer.

Is science important or market important? Soft drink manufacturers obviously do not want to argue academic issues with consumers. PepsiCo, which once again became a target of public opinion, said that the caramel color contained in the company’s food and beverages is safe, but PepsiCo still promised to use caramel color that changed the production process to reduce the content of 4-methylimidazole in caramel. .
