Misinformation

Honey can prevent dental caries? Misinformation
Honey can clean teeth. Honey containing similar lysozyme composition, for a variety of pathogenic bacteria has a strong bactericidal and bacteriostatic ability, regular consumption of honey and pay attention to oral hygiene, prevention of dental caries.
The truth: honey, has been seen as a" natural" "medicine", its" health" and" health" effect has been widely publicized. How to get rid of the" effectiveness" of myth, may have a look." Don't crush the cloud no honey, although it has a beautiful legend". Here only to gossip about" honey caries".
Honey not only can prevent dental caries, but with caries. This not only is supported by animal experiments confirmed [1 ], the people related research also supports multiple edible honey with caries more [2], less consumption of honey were less likely to suffer from dental caries [3 ]. While rumors as caries according to similar" lysozyme composition", just" honey has bactericidal and bacteriostatic ability" a conjecture, not confirmed. Step back, even honey has antibacterial activity does not mean that it has no caries, more do not be equal to caries.
Honey: sugar camouflage, dental caries.
The major components of honey is sugar, containing 30% glucose and 38% fructose and sucrose fraction. Dental caries and sugar and inseparable relationship. Dental caries is caused by bacteria in the mouth, they on the tooth surface adhesion and growth, the formation of dental plaque. Sugar is the most bacteria like food. Bacterial metabolism of sugar produced by acidic substances are most afraid of things teeth minerals, when acidic high to a certain extent, these minerals will begin to erosion, caries also produced. Eat more and more serious, dental caries.
Although different sugar with different caries ability, from strongest to glucose, sucrose, maltose, lactose, and then to fructose, but as long as they enter into your mouth, attached to the teeth, more or less will give you the road to do what little one can to help dental caries. A lot of chewing gum brand launched the so-called " prevention of dental caries of xylitol chewing gum", but also because of use cannot be cariogenic bacteria using xylitol as sweetener, avoiding the more sugar, xylitol itself has no role in caries prevention.
Sugar cariogenic mechanism clear, sugary honey to blame. Population study did find excessive ingestion of honey and caries level was significantly related to eat honey, who are less likely to suffer from dental caries.
Bacteriostatic and anti caries
Honey" caries ", is likely to be of honey antibacterial study of error derivative. The domestic similar propaganda often referred to a man named Mo Lan ( Molan ) scholars, and based on his research and ideas introduced honey caries. This one is the presence of misinterpretation.
Mo Lan is New Zealand's a study of honey biological assistant professor of chemistry. He was a review about the antibacterial activity of honey, have a lot of research results, prompted us to eat honey may reduce dental caries risk, but also need to be confirmed by experiment. If we conclude that he recognized honey can caries, appear not to be sufficient.
Although studies have found that undiluted and high concentration ( 75%) of honey on the in vitro culture of Streptococcus mutans inhibition, but do not see with oral bacteriostasis in terms of feasibility ( no one can" drink" pure honey, very much dead not responsible for ~ ). And the antibacterial mechanism of the hypothesized that, regardless of is the metabolism of glucose to produce glucose oxidase inhibitory effects of hydrogen peroxide, or contain flavonoids have antibacterial action, are not sufficient to support the caries-preventive argument ( can achieve effective concentration? ).
Say you have a look or feel distant not Buddha, Dr William and his colleagues used the rat to do experiments, we can get the" honey and caries" have a more intuitive feeling. Experimental comparison of honey ( 10% dilution ), cola, milk and human milk in caries, below is the result of feeding honey and served as controls feeding distilled water sample.
