Related Episodes for How Vitamin D Status May Shape Dementia Risk

“Dr. van Loon sees useful research questions in skin, joints, and recovery after orthopedic surgery, but he keeps those possibilities separate from established muscle-building effects.”

“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.”

“Circulating LPS can also bind to lipoproteins, facilitating their absorption in the liver during LDL recycling, effectively removing LPS from circulation and lowering systemic inflammation – a phenomenon demonstrated mechanistically with statins that increase lipoprotein recycling by increasing LDL receptors.”

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.”

“00:29:20 - Organs shrink during fasting and then regrow after refeeding. Study. 00:29:45 - Fasting stresses healthy cells so they increase their stress-response pathways, including heat shock proteins, antioxidant production, and anti-inflammatory.”

“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.”

“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.”
