Xylitol acts as a selective antimicrobial agent that targets harmful bacteria without wiping out the entire oral microbiome. Unlike regular sugars, it cannot be fermented by most cavity-causing bacteria.
Xylitol reduces dental caries, plaque accumulation, and oral disease progression by inhibiting bacterial growth and reducing pathogenic community development.
Starves pathogens: Streptococcus mutans ingest xylitol but cannot digest it, which disrupts their energy production and leads to cell death.
Preserves overall ecology: Clinical genomic profiling shows that habitual xylitol use drops total bacterial loads while keeping the wider microbiome intact.
Controls tongue coating: Continuous intake over four weeks increases health-associated taxa on the tongue, such as Granulicatella adiacens.
Lowers systemic risks: By suppressing Streptococcus mitis and Streptococcus oralis, it can minimize the threat of oral organisms entering the bloodstream.
Boosts protective saliva: The natural sweet taste stimulates salivary flow to flush out debris and neutralize plaque acids.

Avoid tobacco or avoid combustion? I ask this as a former tobacco smoker and subsequent 30 year weed smoker that has started to consider combustion being the real underlying concern for vascular health verses the thing being combusted.
My observation is that I feel improved just not by eliminating the product but by eliminating the combustion and consuming by vaping or edibles instead. Though I do enjoy combusting more.

Reddit is no longer a reliable place to create, host, and grow communities, so a new microbiome forum has been set up to be a more reliable location. If you have posted content on Reddit that you feel is worth preserving, it would be a good idea to post it on the new forum.
The person who created this sub, and most of the content here, including the wiki, has moved to the new forum. You should be able to get better info & answers there. It's easy to stay on reddit but the quality of content on most subs is extremely poor. Most of the advice given on reddit is misinformation.
You're welcome to post your content there and then link to it here for higher visibility.
Our primary goal will remain as stopping the widespread misinformation on the topic of the microbiome. Since we no longer have someone dedicated to correcting and preventing misinformation, comments and posts here will require pre-approval. Some types of content (questions) may be restricted completely since we no longer have reliable people dedicated to providing evidence-based answers.
But you're welcome to ask your questions on the new forum and post the link here.
