"And one of the scary things is people, for instance, with dementia have up to fourfold more bacteria in their brain than hopefully you and I do." (said at 0:00:15)
No published record matching the claim that individuals with dementia have up to fourfold more bacteria in their brain compared to people without dementia was located; this does not prove the claim false.
"So, this was a a young woman—young woman, 62 years old, she's a physician... who had developed uh really bad Parkinson's... we had done leaky gut tests on her... we put her on my program... she did not have a tremor... And her downhill that she felt started shortly after he arrived." (said at 0:10:12)
No published record matching the reported clinical case of a 62-year-old female physician experiencing resolution of Parkinson's disease symptoms following dietary treatment for intestinal permeability, followed by relapse attributed to gluten cross-contamination, was located; this does not prove the claim false.
"my father um had Parkinson's uh for about 25 years. Um and he uh when he first developed it, I was just kind of starting in this, and he was act he did not change in 25 years, did not change his medication, did not change his because I taught my mother um to feed him, I guess. Uh and and funny I'll tell you a funny story... but yeah, he did he was he had Parkinson's for 25 years and died of a totally different reason at 91." (said at 0:24:18)
No published record matching Dr. Steven Gundry's account of his father's 25-year course with Parkinson's disease or specific dietary management was located; this does not prove the claim false. Personal anecdotes and unpublished single-case observations cannot be verified against the peer-reviewed medical literature.
"And these fermented sausages, traditional sausages, are fermented. They they have lactic acid bacteria in them. They eat all the Neu5Gc. So these guys are getting great fermented products that doesn't have Neu5Gc. And fermenting milk removes Neu5Gc." (said at 0:44:50)
No published record matching the claim that traditional fermentation of sausages or meats by lactic acid bacteria, or the fermentation of milk, eliminates or removes Neu5Gc was located; this does not prove the claim false. Research has demonstrated that human gut microbiota (such as specific Bacteroidales species expressing specialized sialidases) can liberate and utilize Neu5Gc in the intestine, and Neu5Gc remains detectable in fermented dairy products such as cheddar cheese. However, evidence showing that traditional lactic acid bacterial food fermentation processes degrade or eliminate Neu5Gc from meats or dairy products is lacking.
"We found that a Neu5Gc-rich diet induces changes in the gut microbiota, with Bacteroidales and Clostridiales responding the most. Genome assembling of mouse and human shotgun metagenomic sequencing identified bacterial sialidases with previously unobserved substrate preference for Neu5Gc-containing glycans."

"Neu5Gc-positive N-glycans were identified in reduced-fat sharp cheddar cheese (CHE), whereas such structures were not observed in processed cheddar cheese slices (SLI)." (abstract, results, passage verified)pubmedfull study (doi)
