The cause of cancer is determined by internal and external factors, the internal factor is mainly from the role of genes, while the external factor is caused by bad habits. So, let’s learn about the bad habits that can easily lead to cancer. Eating meat but not vegetables” has become a common problem of modern people, but don’t underestimate the harm brought by this habit. First of all, eating by nature will cause obesity, recent research shows that obesity and breast cancer, prostate cancer and many other cancers related. Secondly, vegetables and fruits contain a lot of dietary fiber, which can promote intestinal peristalsis and take away harmful substances. Often do not eat vegetables and fruits, will increase the risk of colon cancer. Again, eating only meat and not vegetables can lead to vitamin deficiency. Studies show that people who do not eat carrots are 7 times more likely to develop lung cancer than those who eat a lot of carrots, which lack beta-carotene; lack of vitamin A, the possibility of lung cancer and stomach cancer is high; lack of folic acid and vitamin B2 is an important reason for the high incidence of esophageal cancer. To ensure the body needs, you should eat more than 400 grams of vegetables and not more than 75 grams of meat per day, the volume of which is equivalent to the size of a deck of playing cards. Rough food is the best way to keep away from cancer. Many people have to stay up late at night because of work; others catch up with the fashion, soak in bars every day and become “party animals”. The British Scientific Cancer Research Center studied more than 1,000 cancer patients aged 30 to 50 around the world and found that 99.3% of them stayed up late all year round and rested only after midnight. Experts point out that staying up late can cause disruption of the biological clock on the one hand; on the other hand, night lights can damage the formation of melatonin in the human body, which is an important part of protecting the body’s immune function, the lack of which can easily make leukemia, breast cancer, prostate cancer, etc. come to the door. It is best not to stay up later than 12:00. If you work late into the early morning, it is best to find a room with blackout curtains to sleep, the dark environment helps the body in the production of melatonin. Sit down and do not want to move to work a day, home in the couch do not want to move …… do not think that the harm of sedentary only hurt cervical spine, spine. German experts pointed out that the number of human immune cells increases with the increase in activity, sedentary people have fewer immune cells in the body, greatly increasing the probability of cancer; Japanese medical doctors found that most patients with stomach cancer usually eat too much and sedentary; U.S. research shows that sedentary people are 40% to 50% more likely to suffer from colon cancer than those who often exercise, men are also prone to prostate cancer. Experts point out that every 2 hours of work, you must get up and move for more than 15 minutes. Many people like to brew a cup of kung fu tea at leisure, but they do not know that this tea, which is brewed now and drunk while it is hot, may lay a hidden danger for esophageal cancer. The reason is that the boiling water will scald the mucous membrane of the esophagus and cause oral mucositis, esophagitis and so on, and after a long time, cancer may occur. Investigation shows that Kazakhs in Xinjiang often drink boiling hot milk tea, Chaoshan people like kung fu tea, and people in Taihang mountains love to drink large bowls of hot porridge, and currently these areas have become high incidence areas of esophageal cancer, cardia cancer and oral cancer. Experts suggest that if the food or drink is hot, don’t swallow it in a hurry. Eat moldy food Peanuts, soybeans, rice, flour moldy, can produce aflatoxin, which is a strong carcinogen, may lead to liver cancer, stomach cancer and so on. In addition, moldy food has miscellaneous mycotoxins, ochratoxins, etc., which have a strong carcinogenic effect. Therefore, it is best not to eat moldy food. If you feel that the things that make you angry in life like a hurdle, how can not step over, the thought of the bull’s-eye, and depressed state of mind for more than a year or two, be careful. It has been clinically found that people who love to be serious and angry in life and are not good at expressing themselves are in a high state of hyperactivity and tension in their vegetative, endocrine and immune systems for a long time, which is an important cause of breast and ovarian cancer. People who are more serious at work and pursue perfection are more likely to suffer from stomach and pancreatic cancers. Experts point out that an open mind and a happy mood are the natural enemies of cancer cells, so you should cultivate more hobbies and take deep breaths when you are unhappy. Excessive sunlight Furniture that is always exposed to the sun at home ages faster, and to a certain extent, so does human skin.
