“Time-restricted eating exploits the body's innate 24-hour patterns – the genetically encoded molecular clocks present in every cell, from the complex (liver cells) to the simple (hair follicles) – and provides the body an essential downtime where it can focus on DNA and cellular repair and restoration rather than digestion.”
“In a study where 24 middle-aged healthy dogs received either a placebo or a non-immunosuppressive dose of rapamycin three times a week for ten weeks, researchers found that dogs that received the rapamycin exhibited improvements in multiple aspects of heart function, including how well the heart filled and pumped out blood.”
“While aerobic exercise is often viewed preferentially through the lens of cardiovascular health, the diverse cascade of biological effects from exercise as a whole — and aerobic exercise, in particular — culminate to make it one of the most formidable and immediately practical real-world interventions for human aging and the brain.”
“Removing former drinkers from the non-drinker category reveals a different story: One study observed that the lowest risk for cardiovascular disease (i.e., ischemic heart disease) was right below one standard U.S. drink per week — men and women at this level of consumption had an ~18% lower risk compared to nondrinkers.”
“Assessments of episodic memory based on a battery of cognitive tests demonstrated that the rate of cognitive decline experienced by healthy, older people who had amyloid-beta protein accumulation in their brain and who were APOE4 and BDNF Met carriers was roughly three times the rate of decline among those carrying only the BDNF Val allele (the more common form of the gene that retains valine).”
“A mouse study demonstrated that oral berberine (50 or 100 mg/kg/bw per day) reversed the depression-inducing effects of corticosterone injection by upregulating hippocampal synthesis of brain-derived neurotrophic factor – a type of protein that acts on neurons in the central and peripheral nervous systems and may be important for the antidepressant response.”
“However, two small, randomized, double-blind, placebo-controlled experiments in which participants received BHB supplements (as ketone salt or ketone monoester) found that various markers of NLRP3 inflammasome activation, including caspase-1 and interleukin 1-beta, increased, suggesting that the ketones may have unintended proinflammatory effects.”
Biological aging clocks use DNA methylation patterns and other biomarkers to estimate different dimensions of biological aging, including how old the body appears at the molecular level, how quickly aging-related changes are accumulating, and whether lifestyle or medical interventions may be changing the trajectory of aging.
“The most useful next studies would directly test banana-blueberry combinations, compare standardized berry preparations, identify which populations benefit, and follow clinical outcomes rather than relying only on surrogate markers.”
“However, findings from a rodent study indicate that even low levels of nicotine exposure during pregnancy or early in life can increase the risk of sudden infant death syndrome, or SIDS, by inhibiting the neonate's ability to autoresuscitate – the capacity to recover from prolonged periods of apnea, widely considered a causal factor in SIDS.”
