1, health rumors are not credible.
1, shower gel is easy to induce breast cancer.
Rumor tracking: In 20 14, a post about "breast cancer induced by shower gel" spread like wildfire in WeChat circle of friends. According to the net post, shower gel contains a preservative called paraben, which may induce breast cancer after long-term use.
Expert interpretation: shower gel, a daily chemical product, is originally in an alkaline chemical environment. Surfactants are mainly used for foaming, while preservatives, which can keep fresh and prevent corrosion, are rarely used. Since it has been approved as an additive by the relevant departments, it shows that its toxicological and pathological test results are qualified.
Experts believe that the dosage and usage of shower gel are also very important. If you wash it immediately after wearing the shower gel, the amount of preservatives absorbed into the body through the skin is very limited and almost negligible. However, if it is used a lot of times, the shower gel will stay on the skin surface for a long time. In the long run, toxins accumulate too much in the body, which may affect health.
2. Microwave heating food causes cancer.
Rumor tracking: the theory that microwave ovens cause cancer has a long history. In the summer of 20 14, a post entitled "Stop using the microwave oven, it will cause cancer" was madly reprinted on WeChat, saying that the food heated by the microwave oven will produce carcinogens, which once again attracted people's attention.
Interpretation by experts: Microwave only heats water molecules in food, and the food itself has not undergone chemical changes, so it will not produce carcinogens. Qualified microwave ovens have undergone rigorous testing and repeated experiments, and their microwave leakage and radiation are within the standard range stipulated by the state. Normal use will not cause harm to the human body, and will not bring health hazards through the food heated by it.
3. Children's precocious puberty caused by fruit ripening.
Rumor tracking: The news that "a 4-year-old girl in a certain place has precocious puberty due to eating her own ripening strawberries" has spread wildly in the circle of WeChat friends. It is said that fruit farmers use a chemical called "ethephon" to ripen green bananas or strawberries, which will lead to precocious puberty of children, which makes many young parents panic.
Expert interpretation: The reason why fruits are ripe is mainly the need of long-distance transportation and storage. Fu Daqi introduced that the ripening process is to artificially apply ethylene gas or ethylene releasing agent (ethephon) to induce fruits to start ripening, such as bananas, mangoes, tomatoes and other fruits to ripen.
Experts say that the plant hormone ethylene plays the same role in artificial ripening and natural ripening of fruits. Eating naturally ripe fruits will not promote precocious puberty. Similarly, eating ripened fruits will not make children precocious. Can ethephon residue in fruit affect human health? Experts say that food safety can be guaranteed if it is used according to national standards.
At present, there is no scientific evidence that precocious puberty in children is related to fruit ripening. Pathological changes and overnutrition will lead to early sexual maturity. In addition, eating more animal foods can also lead to precocious puberty. Experts remind parents that children should not eat tonics such as ginseng, royal jelly, medlar and astragalus, and should not drink adult functional drinks. These are the real culprits of precocious puberty in children.
Drinking light salt water in the morning can detoxify.
Rumor tracking: 20 14 Many health experts are trying a new method of detoxification and beauty-drinking 500m light salt water on an empty stomach after getting up every morning. Drinking light salt water in the morning is a way to keep fit, and it has spread wildly on the Internet.
Interpretation by experts: Drinking salt and boiled water on an empty stomach after getting up in the morning may lead to an increase in blood pressure and a certain health risk. Under normal physiological conditions, the human body's demand for salt is very small, only 4 ~ 6 grams per day, and the daily diet can completely meet it. It is necessary to drink light salt water only if you sweat a lot or have other special needs. Sometimes gargling with light salt water is an effective way to disinfect the mouth or relieve sore throat. But these are not the same as drinking light salt water, so it is also unnecessary to drink light salt water on an empty stomach in the morning.
For patients with hypertension or patients with other diseases (such as diabetes), increasing salt intake may also increase hypertension, leading to fluctuations in the condition. For example, patients with heart disease have the highest blood viscosity in the morning, and their blood pressure also reaches the first peak, which is also the most dangerous period of illness fluctuation. If you drink light salt water for a long time in the morning, it will undoubtedly raise your blood pressure and may cause a series of pathological changes.
