Original title: September autumn wind, look at these in the family group "by the wind and waves" rumors
summer to autumn, the season alternates, the family WeChat group, in addition to the elders "add clothes" advice, there is a new wave of rumors: "early C night A" must be fixed with the use, plastic packaging of food carcinogenic, eating overnight vegetables will lead to kidney failure, uncooked soy milk poisoning children ... Are these rumors all right in September, when they dance to the autumn wind and "ride the wind and break the waves" in their circle of friends?
. "Morning C night A" must be fixed with the use of
recently, the fashion circle blew up "morning C night A" anti-old matching trend. "Morning C evening A" refers to the use of antioxidant vitamin C products in the morning and vitamin A products with anti-aging function in the evening. Many people see this match as the golden law of skin care.
truth: "Morning C Night A" is not the perfect match for whitening and decay, so the combination is likely to be called to the mouth or to bundle.
Chen Xue, an attending physician at Beijing Tongren Hospital affiliated with Capital Medical University, explains that many skin care products can be used together, and consumers can use them with different efficacy products as long as they are based on their skin quality and product descriptions. And different ingredients between skin care products, generally there is no absolute difference between the advantages and disadvantages, how to choose and match, completely depends on personal preferences.
vitamin C can inhibit the production of melanin, with whitening effect, but the substance itself is very unstable, easy to oxidize in the air, but also vulnerable to light, heat. Vitamin A promotes the production of fibroblasts and improves the structure of collagen in the skin.
there are many different ways to suppress skin aging. Whichever you choose, consider its safety and effectiveness first, and don't blindly follow the trend. Chen Xue advised consumers, it is best to choose large brands, reliable quality skin care products, to avoid "into the pit."
Plastic-wrapped foods cause cancer
Recent rumors that the American Medical Association has discovered the "killer" of cancer- plastic, which prompts consumers not to drink tea, coffee or any hot drinks in plastic cups and not to eat any hot food in plastic bags. Rumor has it that when food is placed in high temperatures, chemicals produced by plastics can cause 52 types of cancer.
Truth: Xu Dong, an associate professor at the School of Food at Central South Forestry University of Science and Technology, says there is no scientific evidence that plastic packaging causes cancer, and the pathogenesies of cancer are so complex that they cannot be simply attributed to plastics. On the market, the formal manufacturers of food plastic packaging are in line with national standards, food safety is guaranteed, food packaging will not cause cancer.
the idea that plastic packaging produces 52 chemicals that contaminate food and cause cancer when consumed is highly unscientific. Commonly used food packaging plastic is a polymeric material, chemically aggregated by monomites, its molecular weight is very large, will not easily migrate to food.
Food packaging falls under the supervision of the Food Safety Law, in which the General Safety Requirements for Food Safety National Standard Food Contact Materials and Products stipulate that the amount of packaging plastic that migrates in contact with food shall not exceed 0.01 mg/kg, and this dose will not contaminate food.
formal food packaging and food production enterprises must go through the relevant government departments of strict review, and the quality of their products must pass the inspection, in order to be awarded a production license. This procedure ensures that the packaging materials are in line with food safety requirements, will not cause harm to the human body.
Eating overnight vegetables can lead to kidney failure
Several reports have recently reported that a patient suspected of eating overnight leftovers, causing acute renal failure. Overnight dishes "toxic" said for a long time, then overnight dishes can not eat it?
Truth: Xu Dong explained that only in individual cases, eating corrupt and bad overnight vegetables will lead to diarrhea, at this time if not replenished in time, the human body is severely dehydrated, will cause kidney isoemia, causing acute kidney failure. Under normal circumstances, people eat a bad overnight dish, only affect the balance of the body, there will be some discomfort, but not serious enough to cause kidney failure.
Overnight dishes are meals stored for more than 5 to 8 hours, and the main reason for the decline in the quality of overnight dishes is the corruption of food and increased nitrite content caused by the proliferation of bacteria.
, how do you handle the overnight dish properly?
the key to reducing the growth of bacteria in food is to cool it down quickly, says Mr Xu. Leftovers should not be placed at room temperature for more than 2 hours, hot weather should not exceed 1 hour, to avoid rapid reproduction of bacteria, uneaten meals should be kept in the refrigerator in time. At the same time, storage should be raw and separate, to prevent bacteria in the refrigerator cross-breeding. Heat it up before serving overnight, heat it to at least 74 degrees Celsius and keep it warm for half an hour, or 85 degrees Celsius and keep it warm for 15 minutes to kill most of the bacteria.
addition, green leafy vegetables, seafood, half-cooked eggs, silver ears, mushrooms, cold vegetables, soy products are not suitable for overnight storage.
The uncooked soy milk poisoned the child
There are rumors that a child drank a cup of homemade soy milk, nausea, vomiting, breathing difficulties and other symptoms of poisoning, although was rushed to hospital treatment, but still died. The cause of the accident was explained that soy milk may not be cooked, which contains a large amount of saponin, which can cause nausea, vomiting, bloating, dizziness and other symptoms. When you drink undercooked soy milk, you will experience these symptoms and, in severe cases, even die.
truth: In response, Xu Dong said, raw soybeans do contain harmful substances such as plant coagulants, saponins and protease inhibitors. Eating underheated soy milk stimulates the stomach, causes vomiting, diarrhea and other symptoms, and affects the digestion and absorption of nutrients. However, it is important to note that only long-term high intake of such substances, will cause some harm to the human body. As a result, they are not "toxic substances" and do not cause poisoning to death.
, how can I drink soy milk safely and healthy?
best way to do this is to heat it up enough to cook it through. When making soy milk, beware of the phenomenon of "false boiling", in which a large amount of foam floats on the soy milk when the temperature reaches about 80 degrees Celsius, making people think it has been boiled. When cooking soy milk, heat it to 100 degrees Celsius, bring to the boil and cook over a low heat for 5 to 10 minutes, so as to completely destroy the harmful substances in the soy milk. In addition, cooked soy milk has a strong aroma, uncooked soy milk will have a soy smell, which can also help us determine whether soy milk is suitable for drinking.
, drinking unripe soy milk can cause discomfort, but it doesn't cause death. Soy milk has a high nutritional value and can be safely consumed after boiling. (Reporter Zhang Yun)
