d%> d= _ d=> The incidence of lung cancer increased in the group taking carotene. As a result, the trial had to be stopped early. Why can eating vegetables rich in carotene protect people but directly using chemicals - carotene cannot protect people? The secret is currently unknown, but this phenomenon reminds us not to deliberately pursue what to use Indian Tarceva to prevent lung cancer. A balanced diet that follows nature is the best anti-cancer diet. To protect yourself, don't let this happen to your kitchen. When your eyes feel the irritation of oil smoke or smoke during cooking or there is too much smoke in the kitchen, it means that the intensity of indoor air pollution is too high. .d/ .
Secondly, there is the relationship between dietary factors and lung cancer. Since smoking is not the main cause of lung cancer in Oriental women, it is not surprising that many people are interested in research on the relationship between diet and lung cancer in recent years. A study in Hong Kong pointed out that indoor air pollution caused by cooking and ancestor worship and burning incense are not closely related to the occurrence of lung cancer in women because most people pay more attention to and strengthen indoor ventilation in this case. Generally speaking, a lack of fresh vegetables and fruits or a high-fat diet in food is considered to be closely related to the occurrence of lung cancer. In particular, lack of vitamins is considered to be a high risk factor for lung cancer. In recent years, many studies have attributed part of the cause of lung cancer in non-smoking women to incomplete combustion of coal in the kitchen and cooking fumes, specifically mentioning that rapeseed oil fumes are more dangerous than peanut oil fumes.
It seems that the issue is not whether indoor air pollution causes cancer but the intensity of indoor air pollution. Thousands of years of cultural accumulation have formed our eating habits. Therefore, indoor air pollution will always exist when we have to eat. The key is to strengthen the ventilation in the kitchen.
However, a recent large-scale trial in Europe and the United States using vitamin precursor carotene to prevent lung cancer in the population has brought discouraging information
Radon has a high affinity for human fat and affects people's health. The nervous system makes a person lethargic and drowsy. Liao Yun said that when buying granite, it is best not to choose red, purple and other brightly colored stones, and be sure to ask the seller for an inspection report when purchasing. Since granite has different usage standards in each environment, buyers must install it according to their own requirements. environment to check whether its products are qualified.
On March 1, the reporter contacted Dong Jinshi, deputy secretary-general of the Beijing Environmental Science Association and a distinguished expert of the National Environmental Protection Products Quality Inspection Center. Picocuries per liter and red, pink and purple granite have higher radon levels.
Pay attention to ventilation in rooms using granite. The application of granite in home decoration is very common, but it is worth noting that using granite in bedrooms and kitchens is very disadvantageous. Liao Yun, secretary-general of the Home Decoration Branch of the Chengdu Building Decoration Association, reminded consumers that kitchens and bedrooms are frequently visited places and are easily exposed to radiation.
Dong Jinshi said that granite will release radon gas. When a person stays in a room with radon gas, the radon gas inhaled into the lungs decays into radioactive isotopes of polonium, lead, and bismuth and adheres to the surface mucosa of the bronchus in the form of metal ions. When they dissolve in body fluids and enter cell tissues, they continue to decay, causing damage to cells and eventually inducing lung cancer and death.
The radon content emitted by the granite stone on the kitchen countertop is. Radon levels in the air at picocuries per liter (a measure of radon gas concentration) have the same risk of causing cancer as smoking half a pack of cigarettes a day. Radon gas released from granite is the leading cause of lung cancer in non-smokers.
At the same time, if granite has been installed in your home, you should pay attention to ventilation. Existing homes can often use ventilation to reduce radon gas concentrations, such as improving ventilation under the floors and using fans to pull radon gas out from underneath.
