Fact: In the past few years, some studies have shown that there may be a link between the use of mobile phones and the increased risk of certain types of brain tumors. After all, mobile phones emit radiation, which can cause cancer. But the key words here are suggestions and possibilities, and the results are far from conclusive.

Many recent studies have expressed doubts about this. Although the World Health Organization added cell phone radiation to its list of possible carcinogens in 2 0 1 1, the list also included items such as pickled vegetables. Dr Richard Besser, chief health and medical editor of ABC News, said that WHO's threshold for possible carcinogens is quite low. He pointed out an important difference: there are different kinds of radiation, and they do different things. Ionizing radiation (including X-rays and some ultraviolet rays) can damage DNA and may lead to cancer. But cell phones emit non-ionizing radiation, which won't damage DNA, Dr. Besser explained. He wrote, Tell me the truth, doctor. Experts agree that since people are getting younger and younger when they start using mobile phones, we need to do more research on the long-term risks.

However, there is ample evidence that mobile phones do pose another direct threat: endangering drivers and passengers. Think about it: sending or reading text messages will take your eyes off the road for an average of 4.6 seconds, which is equivalent to driving the length of a football field at 55 miles per hour ... blind. If you text while driving, the probability of a collision will increase by 23 times. Dr. Besser said: "Research shows that driving while texting is equivalent to drunk driving." . "When you hear an incoming text message, it's easy to pick up the phone. The smartest trick: turn off the phone before getting on the bus, or put it in the glove box. "

Deal with it at home

Last summer, a batch of prepackaged salad vegetables was related to the outbreak of cyclospora, a rare parasite that can cause explosive diarrhea for weeks. Last year, some chopped onions were removed from store shelves because they might be contaminated by Listeria. A year ago, a company recalled about 36 million pounds of turkey products that might be contaminated with salmonella. Food recalls and outbreaks of food-borne diseases will make headlines (in this case, we support the dissemination of awareness). But most food poisoning incidents do not belong to these widely reported incidents. For example, in 2009 and 2065, federal officials recorded only about 30,000 cases of diseases related to disease outbreaks, and an average of 48 million people got sick from contaminated food every year. In other words, the chances of a major news breaking out that affects you are relatively small. What is more likely to make you sick is the habit of spreading diseases in restaurants, cafeterias and even your own kitchen.

According to a paper published by Elizabeth Scott, deputy director of Simons Family and Community Health Center in Boston, many cases of food-borne diseases are caused by improper food handling at home. Some mistakes we will make: about 60% people are unwilling to wash their hands before handling food, although this may reduce nearly half of food poisoning cases. Failure to thoroughly wash agricultural products under running water will expose you to bacteria on the surface. A recent government study found that leafy vegetables account for nearly half of food-borne diseases. Sponges and rags are breeding grounds for bacteria, but about one-third of people will wait a month or wait until the sponges fall apart before replacing them. About 90% people said they would wash raw poultry before cooking, although food safety experts advised against it. This practice will spread bacteria around your sink and cupboard; Cooking poultry to the right temperature will kill any pathogens.
