Camps of opinion · 2Positions people took on this topic in transcripts, grouped by school of thought. The bar shows each camp's share of the people sorted into a camp. It is not a poll and not a share of any audience, and people whose position fit no camp are left out of it. Within a camp, people with demonstrated expertise on the topic come first, then those who reached the most listeners on it. Positions are extracted from transcripts by a model and may misattribute who said what. Every quote links to the episode it came from.

Common oral care products like mouthwash and harsh ingredients damage the oral microbiome and contribute to systemic health issues.

NB
Antiseptic mouthwash and fluoride toothpaste are harmful because they destroy the oral microbiome responsible for nitric oxide production.
“they don't know that most toothpaste and mouthwash is killing the oral microbiome that's partly responsible for production of nitric oxide”

Alcohol-based mouthwashes are detrimental to oral health because they harm mucosal lining and disrupt the healthy oral microbiome.
“most all not all but most all mouthwashes especially those containing alcohol are terrible for oral health simply put they deplete certain components of the mucosal lining of the mouth and they disrupt the healthy components of the oral microbiome”

It is more effective to foster a healthy microbiome by feeding existing bacteria with fiber-rich foods rather than taking supplemental probiotics.
“in order to get meaningful colonization and repopulation of the gut you have to feed them and so the food is ultimately more important because the truth is it's not that you don't have any healthy bacteria in your gut the population is low how do you get well population may be low”

Fasting can help shift the gut microbiome by starving out bad bacteria, and breaking a fast with fermented and prebiotic-rich foods supports the growth of good bacteria.
“When you are in a fasted state, the longer you're there, the most famous study was out of MIT, 24-hour fast, you start to get these stem cells into the gut that repaired the gut. But when you're in a fasted state, these bad bacteria get starved out. And when they get starved out, there's an opportun”
