80% of autoimmune disease cases occur in women.

"80% of autoimmune disease is seen in women. That's a fact." (said at 0:00:05)

No published record matching the claim that 80% of autoimmune disease cases occur in women was located; this does not prove the claim false.

In 1900, myocardial infarction and diabetes were extremely rare clinical conditions in medical practice.

"So what happens is that heart attack in that, you know, 1900 was like a rare disease, right? Diabetes was super rare. In fact, in 1900, I remember reading some of the the original reports saying if there was a heart disease patient in clinic, they used to run over and try to see them because they may not see another one in their practice." (said at 0:02:07)

No published record matching the specific claim that myocardial infarction and diabetes were extremely rare clinical conditions in 1900 was located; this does not prove the claim false.

There is a documented epidemiological correlation between childbearing/pregnancy and the risk of developing autoimmune disease.

"Yes, there is a correlation between childbearing and autoimmune disease." (said at 0:05:21)

No published record matching the claim that there is a documented epidemiological correlation between childbearing and autoimmune disease was located; this does not prove the claim false.

Plains Native Americans had the highest proportion of centenarians of any population at the turn of the 20th century.

"when you look at the historical records, like for example, the Native Americans in the plains, they had the highest number of centenarians of any population at the turn of the last century." (said at 0:06:49)

No published record matching the claim that Plains Native Americans had the highest proportion or number of centenarians of any population at the turn of the 20th century was located; this does not prove the claim false. Anthropometric historical records (such as studies by Steckel and Prince) document that 19th-century Plains Native Americans were among the tallest populations in the world due to nutrition and equestrian hunting before bison depletion, but this is distinct from demographic records of centenarian prevalence, which are subject to substantial age-misreporting artifacts in early census data.

Human blood plasma proteins and mature erythrocytes lack DNA, so epigenetic biological age clocks measured from blood samples reflect the DNA of leukocytes (immune cells).

"Now it turns out that plasma proteins and erythrocytes don't have DNA. So when you're measuring then the biological age of a blood spot sample, you're actually measuring the age indirectly of the immune system." (said at 0:15:30)

No published record matching the specific claim that blood-based epigenetic biological age clocks exclusively reflect leukocyte DNA because erythrocytes and plasma proteins lack DNA was fetched; this does not prove the claim false.

Himalayan Tartary buckwheat contains 121 distinct phytochemicals across the flavonol, flavone, flavanone, and anthocyanin polyphenol families.

"When we analyzed it very precisely for its composition, we found there were 121 different phytochemicals from the polyphenol family across all the various families—the flavonol, flavone, flavanone, and anthocyanin families." (said at 0:51:08)

No published record matching the specific claim that Himalayan Tartary buckwheat contains exactly 121 distinct phytochemicals across the flavonol, flavone, flavanone, and anthocyanin polyphenol families was located; this does not prove the claim false. While Tartary buckwheat (Fagopyrum tataricum) is well-documented in the scientific literature to be rich in polyphenols and flavonoids such as rutin, quercetin, and anthocyanins, proprietary or lab-specific compositional analyses identifying a precise count of 121 polyphenols have not been published in peer-reviewed journals.

Studies in Asian medical literature demonstrate that consuming Tartary buckwheat flour in amounts equivalent to ~1,200 mg/day of polyphenols improves insulin sensitivity, reduces inflammation, and lowers lipid levels in humans.

"And the reason we chose that is that there were data that had already been published in the uh Asian medical literature showing that they could show clinical effects in humans um in terms of improved insulin sensitivity, reduced inflammation, reduced lipids when they fed that amount of flour to individuals." (said at 0:54:26)

No published record matching the claim that consuming Tartary buckwheat flour in amounts equivalent to ~1,200 mg/day of polyphenols improves insulin sensitivity, reduces inflammation, and lowers lipid levels in humans was located; this does not prove the claim false.

Himalayan tartary buckwheat regulates glucose metabolism, improves HDL cholesterol, lowers LDL cholesterol, reduces liver fat, and modulates the AMPK pathway.

"It also has incredible effects on metabolism by regulating glucose metabolism. And the fibers in it help with cholesterol metabolism, improve your HDL and lower your LDL, and helps liver fat and modulates something called AMPK, which is a critical pathway that a lot of people are studying related to longevity." (said at 0:58:07)

No published record matching the specific claim that Himalayan tartary buckwheat regulates glucose metabolism, improves HDL, lowers LDL, reduces liver fat, and modulates the AMPK pathway was located; this does not prove the claim false.

Unverified means no publication matching the claim was located; it does not prove the claim false. Spotted an error? See the corrections policy - disputes from the people quoted are prioritized.
