Subject: Re: CS>Xylitol and sinus fungal infections
While other sugars tend to promote the growth of bacteria, xylitol has been
proven to inhibit the growth of bacteria. In particular it has been shown to
be effective in preventing dental cavities by inhibiting Strep mutans, the
main bacteria responsible for cavities.
Since the major cause of ear infections is Strep pneumo, a species of
bacteria closely related to Strep mutans, perhaps xylitol would prove
effective in preventing ear infections. Researchers from Finland tested this
hypothesis and published the results of their investigation in the British
Medical Journal (November 1996).

The effect of sugar substitutes on changes in S. mutans levels also have
been investigated. All studies have consistently demonstrated that xylitol
use did significantly reduce the levels of S. mutans.

One promising approach is the possible use of xylitol as a dietary agent to
prevent midear infections in young children. This effect is based on the
growth inhibition by xylitol of alpha-hemolytic streptococci, including
Streptococcus pneumoniae. As one consequence of this, the usage of xylitol
chewing gum by young day-care center children was shown to reduce the
occurrence of acute otitis media and antimicrobial treatment received during
the gum-using period (7). It is possible that the virulent bacterial flora
present in the entire aero-digestive tract of man, can be favourably
affected by systematic xylitol use. Xylitol, by virtue of its pentitol
nature, modifies the outer environment of selected pathogenic organisms and
the outer structures of the organisms themselves. Such changes may result in
a lowered ability of the organisms to adhere onto epithelial cell surfaces
and other host tissue surfaces, reducing the risk of infection. It is clear,
however, that the above otitis media-related observations must be verified
by independent studies before further conclusions can be made.
No study has shown that the oral bacteria become adapted to utilize xylitol
for effective acid and polysaccharide production.... Xylitol, being a
natural dietary carbohydrate, must be used at chemical levels corresponding
to those of regular table sugar. Such concentrations are more likely to
display specific effects on oral microorganisms and on oral tissues.

Like maltitol, xylitol is another one of the "sugar alcohols"; but where
maltitol is essentially inert, xylitol produces some very interesting
effects as it passes through the body. Where regular sugar promotes the
formation of dental plaque and the bacteria that lead to tooth decay and gum
disease, xylitol has exactly the opposite effect. It actively combats these
bacteria, due to its powerful antimicrobial properties, making it an ideal
substance to chew on after a meal.
Once it gets into the digestive tract, it does not feed pathogenic yeasts
the way that sucrose does, so it does not encourage candida overgrowth. Nor
does it have the immune suppressing effect of regular sugar. Furthermore,
when it reaches the large intestine, it is converted into short-chain fatty
acids, which then nourish the mucosal cells that line the colon, cells which
play a key role in protecting against colon cancer. If that was not enough,
preliminary research suggests that xylitol may actually improve bone density
and help ward off osteoporosis (though it would need to be ingested in a
greater quantity than you are likely to get through the mints alone).

To enhance the function of this fluid, she postulated that a substance that
lowered the salt concentration in the airway without simultaneously being
absorbed from the upper airway would help prevent the initial tracheal
colonization with bacteria seen early during mechanical ventilation. Xylitol
has such properties and has been used successfully in lozenges to help
prevent recurrent otitis media in children. The primary emphasis of her
current research is to lay the groundwork for a large trial in this area. In
animal models, it has been shown that nebulized xylitol substantial prevents
airway colonization in a model of Pseudomonas aeruginosa. In safety studies
in health adults, nebulization of xylitol appears to have no impact on
either forced expiratory volume in 1 second (FEV1) or airway
hyperreactivity.[10] She hopes to soon answer questions regarding long-term
safety, colonization prevention, and the cystic fibrosis population.

Dear Dr. Dean,
If I may I'd like to ask four ques-
tions about Xylitol:
1) How much Xylitol should I consume
daily to help kill H. Pylori?
2) Should the Xylitol be consumed on an
empty stomach to combat H. Pylori?
3) Will Xylitol feed my candida over-
growth problem?
4) Why does a natural substance
(Xylitol) cause bowel disturbance if
consuming over 50 grams daily?
Thank you for your time,
- Mr. M.
Dear Mr. M.,
I don't know that the amount of Xylitol
required to kill H. Pylori has ever been quanti-
fied. Xylitol doesn't "kill" micro-organisms
(like the bacteria in the mouth that cause peri-
odontal disease, or candida) in the sense that
other anti-microbials kill these organisms. It is
lethal to these microbes because they con-
sume Xylitol, and assume it is sugar (like we
do). If it is their only source of "sugar," they
don't metabolize it (like we don't) and literally
"starve to death."
If Xylitol is the only source of "carbohy-
drate," it will inhibit the growth of

Based on the above, the answer seems to me to be that pathogens that consume
xylitol, thinking it is sugar, die because they can't metabolise it.
Rather like the ants that eat aspartame? Though no, I suppose that is not
quite the same?

My question: does Xylitol feed some pathogens has stimulated a great deal of
traffic on the stuff, but no one has addressed the issue: Does it feed some
pathogens?
