garlic
Garlic has the function of seasoning, but it also contains allylmethylsulfide, which is a chemical that gives strong smell to garlic. When the body digests garlic, it will diffuse blood vessels, overflow from sweat glands and mucous membranes, causing bad breath and strong body odor.
Alcohol
Alcohol is a kind of diuretic, once drinking too much, it will lead to water shortage in the body, especially in the mouth, so there will be dry mouth after drinking. This is because alcohol can hinder the normal secretion of saliva in the mouth. If there is little saliva in the mouth, a large number of bacteria in the mouth will exist in the mouth without saliva. These bacteria often have a very heavy taste, which leads to halitosis. Not only that, the alcohol in the wine will also cause damage to the liver of the body. The liver is the largest detoxification organ of the body. Once the liver is damaged, the detoxification function of the liver will be greatly affected, which will make the toxins in the body unable to be decomposed, and thus the phenomenon of halitosis will occur.
Peanut butter
Peanut butter has a high viscosity, and the residue can not be digested in the cavity for several hours, during which it is quickly eaten by oral bacteria, which secrete sulfur molecules with strong pungent odor.
Carnivorous
Many people like to eat meat, not only because the taste of meat is delicious, but also because the nutrition contained in meat is irreplaceable by other foods. Meat contains a lot of protein and fat, these nutrients can meet the nutritional needs of human body every day. But if people often eat meat, it will lead to excessive intake of protein and fat in the body, which is very easy to get fat. Not only that, once there is too much protein in the body, protein is a very difficult substance to digest. In order to decompose protein, the body will produce ammonia, which is a very smelly gas.
Mint
In people's cognition, menthol is a must for fresh breath. But scientific research shows that many mints claim to be able to clean breath and eliminate halitosis, but they do more harm than good. Once menthol disappears from the mouth, the strange taste in the mouth will quickly rebound and increase. Most mints contain sucrose, the 'bacterial delicacy', which releases sulfides in the process of breaking down sugar, thus aggravating halitosis.
dairy
Dairy products actually contain a lot of protein. One of the disadvantages of protein is that it is difficult to digest. So after eating dairy products, in order to digest and decompose the protein, ammonia will be produced in the body, which will be emitted from the mouth, causing halitosis. Not only that, for some people, dairy products are firmly to resist, because they suffer from lactose intolerance, which causes the body to be unable to digest the sugar in dairy products, and the enzyme or bacteria responsible for decomposing lactose in the human body have abnormal conditions, leading to a large amount of gas released from the gut during digestion, which is emitted through the mouth to form the mouth Stink.
