# Diet and Mouth Mix > Sugar, fiber and acidity change which bacteria thrive. A practical look at food choices and the mouth's microbial balance. ## Guides - [Sugar and Bacterial Acid](https://diet-and-oral-microbiome.patovehi.workers.dev/sugar-and-bacterial-acid/): Mouth bacteria use sugars from food and drink and release acids as a by-product, and those acids can soften the outer surface of teeth over time. - [Fiber-Rich Foods and the Mouth](https://diet-and-oral-microbiome.patovehi.workers.dev/fiber-rich-foods-mouth/): Fiber-rich foods mouth health is a topic with more hope than hard proof: crunchy produce can stimulate saliva and fits a balanced diet, but fiber does not. - [Nitrate-Rich Foods and Oral Bacteria](https://diet-and-oral-microbiome.patovehi.workers.dev/nitrate-foods-and-oral-bacteria/): Some mouth bacteria convert nitrate from foods like leafy greens and beets into nitrite, which the body can use further, and this is an established part of. - [Snacking Frequency vs Snack Choice](https://diet-and-oral-microbiome.patovehi.workers.dev/snacking-frequency/): For your teeth, snacking frequency often matters as much as what is in the snack, because every sugary or starchy bite starts another stretch of acid. - [Water After Meals](https://diet-and-oral-microbiome.patovehi.workers.dev/drinking-water-after-meals/): Drinking water after meals is a simple, sensible habit that helps wash away loose food and sugars and supports saliva. ## About - [About Diet and Mouth Mix](https://diet-and-oral-microbiome.patovehi.workers.dev/about/): not medical advice, how the site is funded and how guides are made ## Optional - [RSS feed](https://diet-and-oral-microbiome.patovehi.workers.dev/feed.xml)
