In the view of western medicine, if a person does not pay attention to personal hygiene, it is easy to infect some viruses and bacteria through his hands and mouth, thus affecting his health. Yes, there is some truth in this. People should talk about personal hygiene, but this is not fundamental. The real "disease from the mouth" should be demonstrated from the perspective of traditional Chinese medicine.

In other words, one must have a deep understanding of one's constitution, whether it belongs to "fire" constitution or "cold" constitution. People with "fire" constitution are suitable for eating foods that can remove fire, such as vegetables, melons and fruits, laver and so on. People with "cold" constitution should eat more beef and mutton appropriately, and then choose the appropriate health preservation technology according to their own constitution, and which foods can be eaten properly. For people with high blood pressure and high blood lipids, both Chinese and western medicine advocate avoiding animal fat, pickled food, fried food and other foods harmful to blood vessels. In fact, these foods are eaten less or even not for normal people, because no one wants their blood vessels to be damaged, but some people just can't control themselves. If they don't eat pork for a day, they will panic. If they don't eat pickles for a meal, they will salivate at the sight of fried food. These people will be desperate to eat.

Both modern Chinese and western medicine believe that the pathogenic organism of cancer is "acidic", and cancer cells can only survive in acidic environment, which requires us to pay attention to getting sick from the mouth, eat more alkaline food, and eat less or even no acidic food. Acidic foods include most foods that will get angry, mainly meat, and alkaline foods include a large number of foods that can clear away heat and fire, mainly vegetables and fruits.

Therefore, I, a person who studies health preservation, advocate loudly here that for your health, please eat less meat, eat more vegetables and miscellaneous grains, drink less, don't smoke, and put an end to diseases from mouth to mouth.
