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.

“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.”

“02:03:18 - A recent study measured omega-3 fatty acid levels from both supplemental and dietary sources in blood and found that for every 1 percent increment in omega-3 fatty acid levels there was a 20 percent decreased risk in all-cause mortality.”

“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.”

“Alterations in magnesium and oxidative status during chronic emotional stress - Young adults undergoing persistent or intermittent stress like anticipating military conflict) experienced substantial decreases in their overall and plasma magnesium concentrations over three months.”

“The mast cells release pro­inflammatory cytokines and proteases that damage the gut, leading to intestinal permeability, a condition otherwise known as “leaky gut.” This leakiness allows bacteria and bacterial antigens to cross the gut’s inner layer, the epithelium, and activate even more immune cells, leading to more inflammation – a key driver in the aging process.”

“While Dr. Rhonda Patrick’s first video focused primarily on the micronutrients found in the various fruits and vegetables she put in her smoothie, this one, in addition to offering some modest changes on the recipe, instead focuses on the beneficial “hormetic” compounds that are NOT micronutrients.”

“A meta-analysis of resistance-training trials found that protein supplementation produced modest additional gains in strength and fat-free mass, with average fat-free-mass benefit plateauing near 1.62 g/kg/day. This is a group estimate, not a precise requirement for every older adult.”

“In a small immobilization trial, five grams per day of omega-3 fatty acids reduced the loss of muscle volume in young women compared with sunflower oil, supporting continued research on omega-3s and disuse atrophy. Heat is the fourth proposed tool.”
