The rumor is that: a survey proved that eating always gulping people, a relatively high probability of suffering from stomach cancer. And chew food can reduce the burden on the digestive tract, reducing the risk of gastrointestinal cancer. Saliva has a strong "menace" effect, allowing the lead to liver cancer culprit aflatoxin toxicity, within 30 seconds almost completely disappeared.
Reply:
While slowly to promote digestion and absorption of some help, but there is no evidence that the cancer gulping and gastrointestinal tract. At the same time there is no slowly so that the "menace" of the role of aflatoxin.
Demonstration:
After the food into the mouth, to go through several processing steps will channel into the stomach. Seemingly simple "eating" movement, in fact, is under common with the mouth, throat and esophagus complete, and the mouth chewing action is the whole process of eating is an important part. Chew chunks of activity can be cut into finely divided solid chyme, mixed saliva so that food becomes soft and easy to swallow. And the act of chewing can stimulate the secretion of digestive juice for further digestion of food and absorption into the digestive tract after prepare. Although chewing digestion and absorption of food has a very important role, but that does not mean therefore eat gulping can cause digestive function disorder.
There are a number of about 70-year-old teeth to bite (upper and lower teeth to produce the correct number of the contact), chewing function and study the relationship between functional dyspepsia and found that chewing poor performance and functional dyspepsia related. But the wonders of the study is that the study shows that the number of bite and chew performance related, but also chewing performance and functional dyspepsia related, but only to find nothing to bite on the incidence and the number of functional dyspepsia. Considering the small sample size of the study, p values derived from the relationship between masticatory performance and indigestion are also in a very subtle 0.04 this level (odds ratio = 3.46, confidence interval is in a very delicate [0.99 , 12.10]), we find it difficult to judge the study of chewing and dyspepsia relevance in the end is true, or a statistical trap. And another study is that the chewing function caused by tooth loss does not significantly affect the patient's intake of macronutrients, has nothing to do with indigestion.
Habit of chewing on other gastrointestinal tumors, it is unfounded. Large-scale epidemiological survey, and dietary factors associated with gastric cancer, the use of too much salt or nitrite intake increases the risk of developing cancer, and fresh fruits and vegetables can reduce the risk of developing cancer, which is currently the mainstream medical community awareness. No evidence that slowly can prevent gastrointestinal cancers. Want prevention of gastrointestinal cancer, if you want to work hard in the diet should be more focus on eating fresh fruits and vegetables, eating pickled foods, eat less salt, etc. "China Nutrition Dietary Guidelines" recommended healthy eating recommendations on.
Gulping and other bad eating habits combined also may increase the risk of morbidity. For example, some regions have the habit of eating too hot, if you eat too hot food, because of the temperature of the food will not chew it swallowed into the esophagus, the food is too hot it is possible to burn the esophagus. After repeated damage the esophagus hot food, over time the formation of chronic inflammation, and therefore will greatly increase the risk of suffering from esophageal cancer.
On the other hand, rumors mentioned aflatoxin is a highly toxic biological toxins have been IARC (IARC) identified as a Class 1 carcinogen (carcinogenic to humans confirm the sex), it is worth mentioning is a class 1 carcinogen list also can cause hepatitis B hepatitis B virus (HBV). Aflatoxin can cause liver cancer, aflatoxin but not the only causes of liver cancer, not even the most common cause. China is the most common cause of liver cancer in hepatitis B virus infection, followed by aflatoxin liver damage caused by alcohol or plain.
Saliva did not make the "menace" of the role of aflatoxin, if someone listened to what others believe chew can eliminate aflatoxin toxicity, thus boldly eating moldy food, it will lead to disastrous consequences.
