“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.”

“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.”

“The question of whether NAD+ is derived directly from NR or NMN in certain tissues rather than being salvaged from nicotinamide may, in particular, have implications for whether or not oral administration may be hampered in achieving maximal NAD+ status due to the fact that the process of salvaging NAD+ from nicotinamide is subject to feedback inhibition.”

“A randomized-trial meta-analysis found a higher atrial-fibrillation risk with marine omega-3 supplementation, with a stronger signal at doses above 1 gram per day; the included populations generally had cardiovascular disease or elevated cardiovascular risk.”

“EPA and DHA play particularly important roles in heart health because they participate in pathways involved in the production of hormones that regulate blood clotting and inflammation, help maintain healthy heart rhythms, and influence the contraction and relaxation of arteries.”

“Dr. Bruce Ames' Triage Theory Dr. Ames proposed that the body does a strategic rationing so that those proteins and enzymes in the body which are essential for short-term survival get their share of vitamins and minerals at the expense of other proteins and enzymes that are essential for long-term survival.”

“Dr. Patrick also discusses STEP 5, in which two years of treatment produced about 15.2 percent loss versus 2.6 percent with placebo, with the curve leveling while participants remained on treatment. Dual GIP/GLP-1 therapy can produce still larger losses in some trials.”
