Why is lung cancer increasing? Nowadays, the incidence of tumors is really increasing, especially lung cancer, which has doubled compared to ten years ago. Every time I see an outpatient, I can find several cases. I often see many family members with serious faces accompanying the patients to the clinic, without asking, they are suspected tumors in local hospitals and come for further verification. Facing the patients, I can only explain that it is not a tumor, and make the patients “turn to sunshine” first, and then tell the families the truth behind. In 2000, the number of lung cancer cases in China was more than 100,000, and it is expected that by 2025, it will reach more than 1 million, the peak has not yet arrived, but will be more and more. In the past, 40% of lung cancers were squamous type, but now I feel that more than half of them are glandular type lung cancers, and the incidence pattern has changed significantly. Squamous lung cancer is generally associated with smoking. Since squamous lung cancer is becoming less and less common nowadays, how significant is the emphasis on quitting smoking to stop the occurrence of lung cancer? Among the tumor patients I have contacted, there are many in remote mountainous areas where the air is clean and free from pollution, but there are not many lung cancers, and it seems that air pollution is not the main reason. Others say that the food nowadays is unsafe, with preservatives, coloring, gutter oil, and it is impossible to prevent them. I don’t think these are the main reasons for the high incidence of tumors, and in the era of food rout, these are the delicious food we can’t wait for. There is only junk eating, not junk food. There is also PM2.5, which we are now mindful of, but the incidence of lung cancer has not decreased in coastal areas like Qingdao. What is the reason for the high incidence of lung cancer? Nowadays, people are rich in material life, compared with decades ago, they can eat with their bellies, so, even if the food is environmentally friendly, will too much food not lead to the high incidence of tumor? Our body is originally very sophisticated and has evolved various mechanisms to cope with cold, hunger, and shock, and it has its own set of mechanisms to be admired. Only when faced with the problem of eating too much, the body’s commander is lost, because in the history of evolution, this problem has never been encountered. We are now promoting the idea of eating three meals a day, at the right time, whether we are hungry or not. The purpose of eating is to provide energy and stay alive, but we still have to eat a lot when we are clearly not lacking in energy. Our body has to work hard to break down, consume, metabolize, and excrete this food. In the past, when life was hard, the body carefully collected the energy it ate in, converting glucose into calories and breaking down proteins into amino acids, which were then used as raw materials to synthesize its own proteins, without wasting any of it. Now, this thrifty style that our organism has evolved remains unchanged, but the situation is very different, unusually rich nutrients are constantly delivered in, glucose can not be used to turn into fat storage, the most worrying is the protein, the decomposition of a large number of amino acids piled up like a mountain, how can not be used up, but can not be arbitrarily dumped, but used to synthesize tumors. What we are worried about happened From ancient times, when the body is hungry, it will send out instructions to eat, never enjoyed three meals a day, think of the lions on the prairie on the line, not hungry, will not go hunting. Imagine our ancestors went out hunting in the morning, perhaps until the evening to get a full meal, perhaps hungry until the next day. This is how our bodies evolved, and not much has changed to this day. The state of hunger is the best exercise for us, and it is this exercise that we lack now, instead we are used to eating three meals a day, at the right time. Due to the conditioned reflex, not to eat at the point of hunger, this hunger is not real hunger, but the conditioned reflex formation of food dependence. Just like nicotine dependent people, when they see a cigarette, they want to smoke, in fact, they live the same without smoking, and live better. So the modern version of “disease from the mouth” refers to the ease of disease due to the inability to control their mouths, eating too much. A few years ago, an entrepreneur in Beijing went to a mountain in Sichuan and followed a Taoist to practice Purgatory for 15 days, drinking only water, not eating, and doing some pujas every day. Although he lost weight, he was in good spirits. And at the same time in the outside of each mortal, this period but to consume a large piece of meat, a large pile of steamed buns, a table of snacks, a blue fruit, excrement a face basin can not hold, and so on. Think about all this is superfluous. If people cut their current meals in half, the number of patients in hospitals would also be cut in half. With the food crisis solved, we could take out arable land for real estate development, and at least the building spacing would get bigger. As people metabolize less and fart less, global warming will slow down. Of course, people excrete less, rivers will become clearer, and eutrophication is solved. The only drawback is that it will not boost domestic demand and GDP will drop.
