What is the 2019 Top 10 Science Rumor Ending List revealed by Popular Science China?

10 kinds of foods such as Songhua eggs and pork liver cannot be eaten, steamers cannot be steamed with lids, and onions can kill cold viruses. Today (March 1), the Beijing Municipal Association for Science and Technology, the Beijing Municipal Cyberspace Administration and others released the February 2018 "science" rumor list, refuting the recent "rumors".

The official refutes the rumor of "10 foods that cannot be eaten".

There are rumors that Songhua eggs contain lead and cannot be eaten. The official rumor-refuting article pointed out that more than ten years ago, China began to improve the process, and now as long as it is a regular brand enterprise, the large-scale production of standard Songhua eggs can basically control the lead content at about milligrams per kilogram.

In addition, pig liver is the metabolic and detoxification organ of pigs, and the cholesterol is high, but this does not mean that pig liver cannot be eaten. Pork liver contains a lot of nutrients, especially iron. Eating pork liver in small amounts and many times is a good way to avoid toxins and get the nutrients in it, so it is best to buy your own branded pork liver and cook it at home.

However, people who are obese, overweight, and have high cholesterol should try not to eat it.

For roast beef and mutton, the "Rumor List" explains that the meat skewers are grilled directly at high temperatures, and the decomposed fat drops on the charcoal fire, and then combined with the protein in the meat, benzopyrene will be produced, and the International Agency for Research on Cancer classifies benzopyrene in the first group of carcinogens (it has been clear that it has carcinogenic effects on humans). There are more benzopyrene in smoked and baked foods and high-temperature fried foods, so you should stay away from benzopyrene and eat less smoked and fried foods.

Can steamed food with lid on the lid cause cancer?

There is a rumor that when cooking in a pot, you can't use tap water directly, but always use boiling water, or filtered water. Otherwise, the chlorine in the tap water will be covered with carcinogenic hazards because the lid is covered.

The truth is that the amount of chlorine added to tap water is quite low and almost negligible. In addition, the International Agency for Research on Cancer (IARC) classifies chlorine as "Group III" in the "carcinogenic classification", which means that "there is not enough information to determine whether the substance is a human carcinogen". In addition, when steaming and cooking the stuff mentioned in the rumor, the chlorine will be covered by the lid of the pot, and it is impossible to wrap it on food such as steamed buns.

Can you kill cold viruses with onions?

In February, there were also rumors that onions had the effect of absorbing germs, and that keeping an onion cut off at both ends at home would prevent the flu.

The truth is that although onions contain organic sulfides, if you eat some every day, they will indeed have a certain inhibitory effect on bacteria in the respiratory tract and intestines. But when onions are placed in the room, the sterilization effect is minimal. Moreover, many flu are caused by viral infections, and onions have no inhibitory effect on viruses.

Mobile phone and wifi radiation affects health.

Cooking food in the microwave can cause cancer.

Blowing wind is a high-radiation killer.

The radiation from using a hair dryer three times in a row is equivalent to one X-ray, and there is a saying that has been circulating on the Internet. It is also said that using a hair dryer to blow hair on the hair is very lethal if it is applied to the head for a long time and at close range. Truth:

Zhang Zhiqiang, director of the Environmental Protection Office of Peking University, said that ionizing radiation represented by X-rays and nuclear radiation will cause harm to the human body due to its short wavelength, high frequency and high energy, and long-term exposure to ionizing radiation may damage the genetic system or cause cancer. Household appliances, on the other hand, only produce electromagnetic radiation and do not produce ionizing radiation. Everything in nature has electromagnetic radiation as long as the temperature is above absolute zero, which is unavoidable.

As long as the household appliance is a qualified product, its electromagnetic radiation value is within the safe range.

Rumors that seem to be "scientifically reasonable" are deeply rooted in people's concepts, and even if they are debunked by experts, they will still make a comeback. If left unchecked, it is likely that some wrong behavior will damage your health.
