Academicians give cancer-causing food a verse

I don't know when, the words "food" and "carcinogenic" are closely linked, as long as the search engine input "food" and "carcinogenic" two keywords, the computer screen will pop up thousands of related pages, cola, instant noodles, and even milk, soy milk, these foods we often eat are called "carcinogenic".'t that really the case? Chen Junshi, a member of the Chinese Academy of Engineering and a researcher at the National Food Safety Risk Assessment Center, summed up some of the most commonly misunderstood "carcinogenic foods", and a number of experts read them one by one, which is worth a look.of the theory that overnight dishes are carcinogenic, overnight dishes produce nitrites, which are carcinogens., an overnight dish, says that "overnight dishes" can produce nitrites when they are not properly preserved and stored for too long, depending on the type of vegetables. However, nitrite itself is not a carcinogen, but can be ingested with other foods, drugs, residual pesticides in the secondary amine reaction to form a carcinogen - nitrosamine., whether it is carcinogenic depends on how much dose. Experiments show that although the nitrite content of overnight vegetables has increased slightly, the content is limited and does not have a substantial effect on human health.Instant noodles on instant noodles harmful rumors never stop: there are instant noodles containing preservatives, antioxidants, eat too much will become "mummies"; instant noodles bowl wall wax layer, after eating will accumulate in the body leading to cancer and so on.the truth instant noodles Chen Junshi said, instant noodles, although not a health food, but about its "harmful" rumors are not reliable. Preservatives and antioxidants in instant noodles are common food additives, safety is scientifically assessed, as long as the legal use, will not have an impact on human health.worry about paraffin in instant noodles bowls. Now the paper cup used in instant noodles production is actually a polyethylene-coated paper cup, this paper cup can withstand the temperature of the bubble surface, and very good water isolation effect, and wax cup has long been eliminated.consumers need to understand that whether to eat nutrition mainly depends on whether the food is diversified, eating instant noodles nutrition is not balanced, but will not cause cancer.there are rumors that soy products contain a lot of phytoestrogens, which can cause breast cancer in women and so on.truth soy milk in fact, phytoestrogen in soy products is not equal to human estrogen. Phytoestrogens in soybeans are mainly soy isoflavones, which have a two-way regulatory effect, the body estrogen is low it makes up for the deficiency, can prevent some of the diseases associated with the decline in estrogen levels, such as menopausal syndrome and osteoporosis;, you don't have to worry about soy milk leading to breast cancer. The Dietary Guidelines for Chinese Residents recommend eating 30 to 50 grams of soybeans per day, equivalent to drinking 800 to 1200 ml of soy milk.'s claim that cola is carcinogenic was first announced by the
CSPI
, a consumer rights group in the United States, said cola's caramel pigment contained 4-methyl methamphetol, which it said could cause cancer.Fast CokeCola's cancer-causing claims were first reported in a statement from the
CsPI
, a consumer rights group in the United States, which said cola's caramel pigment contained 4-methyl methamphetol and that the substance could cause cancer. In fact, caramel pigment is a synthetic pigment, the production process does produce a by-product - 4-methyl mide.the scientific community on the safety of caramel pigment is quite sufficient, the United States and the European Union, etc. as a very safe food pigment. As for its by-product, 4-methyl methamphetazole, the U.S.
FDA
assessed that the substance is not considered a threat to human health and can only cause cancer risk if a person drinks more than 1,000 cans of cola a day.microwave food once had an article called "Please stop using microwave ovens now" that went viral on the Internet. The paper points out that microwave oven heating can change the molecular structure of food, creating new molecules that the body cannot recognize, and these strange new molecules are toxic and may even cause cancer. Zhihong, an associate professor at the School of Food Science and Nutritional Engineering at China Agricultural University, points out that microwaves are only water molecules that heat food, and that the food itself does not have chemical changes and does not produce carcinogens. lu Jianguo, director of the comprehensive inspection department of the National Household Appliance Quality Supervision and Inspection Center, also said that the quality of qualified microwave ovens have under been rigorously tested and repeatedly tested, and that the amount of microwave leakage and the radiation produced are within the standards set by the state, normal use, will not cause harm to the human body, not to cause harm through its heated food. consumers should pay more attention to how to use microwave ovens correctly, such as avoid heating time is too long, do not put ordinary plastic containers, plastic bags, etc. into the microwave oven heating, avoid the use of closed containers, avoid heating eggs and other shelled food. that milk is carcinogenic has been circulating, one of which is that
IGF
-1 in milk stimulates the growth and reproduction of cancer cells, causing cancer. Truth Milk Chen Junshi pointed out that the full name of
IGF
-1 is insulin-like growth factor, it is a hormone-like protein secreted by organisms themselves, which plays an important role in blood sugar control, growth and development. The human body itself
IGF
-1, a daily production of 10 million nk in an adult. The milk contains
IGF
-1 content of about 2.45 gg/ml, far less than the amount in the human body. At present, the scientific community assessed that
IGF
-1 does not cause cancer. also claim that casein in milk can cause cancer. It originated in a "rat experiment" by Colin Campbell, a professor at Cornell University in the United States, in which rats were fed the carcinogen aflatoxin, as well as soy protein or casein, and the results showed that casein was relatively more likely to promote aflatoxin-induced cancer. Chen Junshi said aflatoxin is already a carcinogen, without it, neither casein nor soy protein will cause cancer in rats. Therefore, this animal experiment cannot be used to analogy the carcinogenic effects of milk. In fact, milk is rich in calcium, and easy to digest and absorb, drinking every day is conducive to calcium supplementation. Mushrooms an article entitled "Mushrooms or eat less" has been circulating in WeChat friends circle, the article said, a professor from the University of Zurich, Switzerland, studying fungi, said that although mushrooms are good, but it is strong on lead, mercury and other heavy metals, the ability to collect up to 100 times. Xinying, director of the Institute of Nutrition and Food Hygiene at Shandong University, said mushrooms do have a high ability to collect heavy metals compared to certain foods. However, whether the mushroom is heavy metal exceeds the standard is mainly related to its growing environment. Most of the mushrooms now on the market are grown in mediums made with some agro-for-forest by-products such as cottonseed shells and bran, so their exposure to heavy metals is particularly small, let alone over-standard. addition, mushrooms contain polysaccharides, an ingredient that inhibits the dissogradation of heavy metals, making them ionic in the body and therefore difficult to absorb by the intestines. So even if people eat mushrooms, the impact on the human body is relatively small. made tea in a stainless steel cup last December, a video was filmed saying that the cup had "corroded" 72 hours after making tea from a stainless steel cup. Because stainless steel contains the toxic heavy metal chromium, it is released into the tea. truth stainless steel cup of tea in the United States Purdy University Department of Agriculture and Biology, food engineering doctor Yun mindless said, to corrode stainless steel is not easy. Stainless steel is soaked long enough under strong corrosion conditions to cause corrosion results that are visible to the naked eye. tea is close to neutral, the ion strength is also very low, almost non-corrosive, and less likely to cause visible corrosion within a few tens of hours. Perhaps the largest amount of tea scale is deposited on the cup, which is used as "corrosion". addition, stainless steel in some cases will be corroded, and some parts of chromium dissolved, but the content is very small, daily use of stainless steel utensils in line with national standards need not worry.
