“Dr. Rhonda Patrick discusses how conditioning the body to heat stress through sauna use, called "hyperthermic conditioning" may cause adaptations that increase athletic endurance (by increasing plasma volume and blood flow to heart and muscles) and potentially even muscle mass. She also discusses the profound effects of hyperthermic conditioning on the brain including cognitive function.”

“Insulin-like growth factor 1 (IGF-1) plays a role during childhood for growth and continues later in life to have anabolic and neurotrophic effects. IGF-1 is also implicated in contributing to aging and enhancing the growth of cancer after it has been initiated.”

Many of the anabolic effects of growth hormone are thought to be mediated by insulin-like growth factor-1, or IGF-1 (https://www.ncbi.nlm.nih.gov/pubmed/18500379), which is synthesized primarily in the liver but also in skeletal muscle in response to growth hormone.

“More importantly, however, these effects were sustained – even after several months – demonstrating that sulforaphane did not exhaust the body's capacity to protect itself from environmental threats and suggesting that regular consumption of sulforaphane in foods or dietary supplements provides a kind of nutritional "seatbelt" that protects against future toxic exposures.”

“Study. 01:43:00 - High animal protein intake was only positively associated with cardiovascular mortality among individuals with at least one unhealthy lifestyle risk factor, such as obesity or sedentary lifestyle. Study.”

“01:52:55 - Environmental enrichment creates epigenetic changes that benefit learning and memory in rodents and these benefits transfer to offspring. Study. 02:05:00 - NASA study showed that gravity influenced expression of genes involved in metastasis.”

“00:34:40 - Repeated traumatic brain injury has cumulative neuroinflammatory effects in the brain over years, including amyloid-beta plaque and tau tangle formation. Study. 00:44:00 - A variant of the APOE gene increases risk of developing Alzheimer’s disease as much as 15-fold.”

“New Scientist article. 02:06:10 - Some people, like Tom Cruise and Keanu Reeves, seem to defy aging. 02:08:15 - One 12-ounce can of sugar-sweetened soft drink per day shortened telomere length, corresponding to 4.6 years of biological aging.”

“Some of the factors contributing to these variable phenotypes include persistent damage to our DNA and mitochondrial dysfunction, driven by an altered NAD:NADH ratio, the latter of which has recently been shown to be improved by certain dietary supplements like nicotinamide riboside.”

“A later Framingham analysis followed 2,240 adults for 11 years and found that a red-cell fatty acid model including the Omega-3 Index predicted all-cause mortality about as well as a model using several standard cardiovascular risk factors.”
