Recently, a "blacklist of top ten carcinogenic foods" was circulated in a circle of friends: "Now Chinese people have a high incidence of cancer, and they have received it! Sunflower seeds rank first in carcinogenesis, while fried dough sticks rank tenth. The blacklist of the top ten carcinogenic foods: sunflower seeds, chewing gum, monosodium glutamate, pork liver, rice noodles (slats, rice noodles, vermicelli), pickles (dried radish), bottled fresh fruit juice, preserved eggs, stinky tofu and fried dough sticks.

Where did this list come from? The reporter found through online search that the publisher of the "Top Ten Cancer-causing Food Blacklist" is the Cancer Hospital of China Academy of Medical Sciences. However, as early as 2014, the relevant personnel of the Cancer Hospital of China Academy of Medical Sciences denied publishing this "blacklist" when interviewed by the media.In 2014, the cancer-causing foods published by Cancer Hospital of China Academy of Medical Sciences were actually cured and smoked foods, barbecue foods, moldy foods and so on.
So, will the food on this so-called "blacklist" really cause cancer? After consulting a lot of information, the reporter summarized the experts’ views on these foods-
Sunflower seeds:
The saying that sunflower seeds rank first among the "carcinogenic foods" will make a fuss on the Internet every once in a while, mainly based on the fact that sunflower can easily absorb heavy metals. But the crops that absorb heavy metals are more than just sunflowers. If the soil itself is polluted by heavy metals, then not only the sunflower will have problems, but also any plants growing on it will have problems. Conversely, if there is no pollution problem and it meets the national standards, sunflower seeds can be eaten normally. For sunflower seeds, what we really need to worry about is deterioration and aflatoxin, which does cause cancer. When you encounter such broken sunflower seeds, you must discard them.
Monosodium glutamate:
Regarding the statement that "monosodium glutamate causes cancer", Jiefang Daily Shangguan News had a rumor in 2016. MSG is not a chemical synthesis, its ingredients are taken from nature. The main component of monosodium glutamate is sodium glutamate, which is fermented by bacteria that are good at secreting glutamic acid. The raw materials for fermentation can be starch, beet, sugarcane and even waste molasses, and the process is similar to the production of wine, vinegar and soy sauce. Jiang Hong, a nutritionist in charge of the Nutrition Department of a hospital in Hangzhou, once said in an interview with the media: "The main component of monosodium glutamate is sodium glutamate, which is composed of glutamic acid and sodium, and glutamic acid is one of more than 20 amino acids needed by the human body. Theoretically, its safety is beyond doubt." Secondly, sodium glutamate evolved into sodium pyroglutamate after high temperature, and its carcinogenicity has not been confirmed yet.
Pig liver:
Pig liver is a metabolic detoxification organ with high cholesterol, but this does not mean that pig liver can’t be eaten. As a natural food, pig liver also contains a lot of nutrients, especially iron. A considerable number of anemic people in the urban population, especially women and children, can eat some pig liver. How to avoid toxins and get nutrients from pig liver? A few times is a good way, and it is best to buy branded pork liver and cook it at home. In addition, people who are overweight and have high cholesterol should try not to eat them.
Stinky tofu:
It is rumored that stinky tofu contains volatile basic ammonia and hydrogen sulfide and is easily contaminated by microorganisms. In fact, stinky tofu "smells stinky" because the protein contained in tofu undergoes a series of reactions in the process of fermentation, pickling and post-fermentation, which eventually produces a pungent compound called hydrogen sulfide. However, after the decomposition of protein, amino acids are produced, and stinky tofu has a delicious taste, so it is "delicious". Therefore, the stinky tofu made by traditional fermentation method is safe. What is really unsafe is that illegal traders cut corners and use illegal additives in the production process.
Fried dough sticks, rice noodles and preserved eggs:
Fried dough sticks, rice noodles and preserved eggs are questioned, mainly because of the harm of heavy metals such as lead in the production. Excessive intake of heavy metals can easily lead to toxic reactions such as insomnia, anemia and mental retardation. Although this is not the same as carcinogenesis, these kinds of foods cannot be eaten without restraint. At present, there are some new technologies in the market, such as alum-free fried dough sticks, healthy rice noodles and lead-free preserved eggs, which reduce the influence of heavy metals.
Chewing gum and bottled juice:
The main entanglement of these two kinds of foods lies in the "sugar". Some chewing gum contains aspartame, and experts say that as long as the chewing gum is not swallowed in a whole bottle, it will generally not reach the carcinogenic concentration. The biggest hidden danger of chewing gum is that chewing time is too long, which will cause oral muscle strain. Bottled fruit juice, whether freshly squeezed or refrigerated or at room temperature, has a considerable sugar content, so long as it is not consumed in large quantities for a long time, it is no problem.
Pickled vegetables:
Pickled food is really not so healthy, and it is most necessary to be vigilant on this list. Almost all pickles and pickles will produce nitrite in the pickling process, and nitrosamines converted from nitrite are carcinogens proved by scientific research. The content of nitrite in food is the highest within 24 hours to 20 days after salting. After more than one month, the content of nitrite decreased to a safe range. Therefore, attention should be paid to the time of eating pickled food, and it is not appropriate to eat it in large quantities.
From this, it can be determined that the "top ten cancer-causing food blacklist" transmitted by the Internet is not credible. Apart from the fact that the "top ten cancer-causing food blacklist" is false, there is also a "list of cancer-resistant vegetables" on the Internet, which is also false because it is spread everywhere under the guise of the nonexistent "the State Council Cancer Prevention Office".

The so-called "the State Council Cancer Prevention Office" does not exist, and this list is also false.

What exactly is a healthy diet? The Dietary Guidelines for China Residents (2016) suggests that the recommended daily consumption of vegetables and fruits in Chinese is 300-500g and 200-350g, respectively, while the recommended daily consumption of livestock and poultry meat is only 40-75g. Remember, eat more vegetables and less meat! Look at the picture at a glance ↓
