In our daily lives, when it comes to lung cancer, many people first think of smoking. Indeed, smoking is recognized as one of the leading risk factors for lung cancer. But with the deepening of scientific research, we are surprised to find that some of the "vegetables" we eat daily can be as harmful to the lungs as smoking, or even worse. This finding not only challenges our conventional wisdom about healthy eating, but also provides a new explanation for the increasing number of lung cancer patients year by year. 
Globally, the incidence and mortality of lung cancer remain high. According to the World Health Organization, lung cancer is the leading cause of cancer death. This fact reminds us that there are more details of life that we need to pay attention to, especially eating habits, in addition to quitting smoking. However, you know what? Some seemingly harmless foods are actually potentially harmful to the lungs, sometimes even more harmful than smoking. Smoking is widely recognized as a major contributor to lung cancer, and the mechanism behind it is not just that the carcinogens in the smoke act directly on the lungs. Tobacco smoke contains a variety of known carcinogenic chemicals, such as polycyclic aromatic hydrocarbons and nitrosamines, which can directly damage the DNA of lung cells, triggering mutations that increase the risk of lung cancer. Studies have shown that smokers have a 15- to 30-fold risk of lung cancer compared to non-smokers. More notably, smoking can also weaken the immune response in the lungs, making the lungs more susceptible to infection, further increasing the risk of lung cancer. However, smoking is not the only cause of lung cancer. Environmental pollution, occupational exposure, and genetics are also risk factors for lung cancer. This means that even non-smokers can be at risk of lung cancer because of these factors. Therefore, a comprehensive understanding of the relationship between smoking and lung cancer requires the recognition that smoking is an important but not the only risk factor. In recent years, scientific research has gradually revealed the link between dietary habits and lung cancer risk. Certain types of foods, such as processed meats and high-salt foods, have been found to be negatively associated with lung health due to the chemicals they contain, such as nitrites. These substances can form carcinogenic nitrosamines in the body, increasing the risk of lung cancer. In addition to direct chemical injury, unhealthy eating habits can lead to weight gain and obesity, which in turn increases the risk of lung cancer. Obesity can lead to increased levels of inflammation and hormone imbalances, all of which are thought to be associated with an increased risk of lung cancer. In addition, a lack of adequate intake of fruits and vegetables has also been linked to an increased risk of lung cancer. Fruits and vegetables are rich in antioxidants, which can help defend against DNA damage caused by free radicals and reduce the risk of lung cancer. Therefore, improving dietary habits, reducing the intake of processed meats and high-salt foods, and increasing the intake of fresh vegetables and fruits can not only improve overall health, but also play an important role in preventing lung cancer. This approach to prevention is equally applicable and important for all populations, both smokers and non-smokers. 
Smoking has long been regarded as the number one cause of lung cancer in the public consciousness. However, new research reveals that certain daily eating habits may have a more negative impact on lung health than smoking. These two types of food are frequently consumed by us every day, but they often ignore their potential harm to the lungs. 1.High-salt foods: "Salt that threatens lung health", as a condiment, is the first killer of lung health while improving the taste of food. A high-salt diet not only triggers high blood pressure and increases the risk of cardiovascular disease, but also indirectly affects lung function. Studies have pointed out that excessive salt intake can interfere with the water balance in the body, increase lung inflammation, reduce lung immunity, and provide soil for the occurrence of lung cancer. 2.Processed meats: Hidden chemical carcinogensAnother major threat to lung health comes from processed meats on our tables. The nitrites and other chemical preservatives in these meat products, some of the carcinogens formed during processing, have been found to be closely related to lung health. Long-term intake of these foods increases the risk of lung diseases, including lung cancer. Recognizing these risks, how can we adjust our diet to protect our lung health? 1.To promote a low-salt diet, reducing salt intake is key. Try substituting natural flavors and herbs for salt to flavor and reduce the salt content of your food. For example, using lemon juice, minced garlic, ginger, herbs, etc., not only adds flavor to food, but also helps maintain lung health. 
2.Choose unprocessed fresh meatFor the choice of meat, it is recommended to choose fresh, unprocessed meat as much as possible. Fresh fish, poultry and lean meats are not only nutritious, but also free of chemicals that are harmful to the lungs. At the same time, increase your intake of fresh vegetables and fruits, which are rich in antioxidants, which are effective in fighting lung diseases.
