“A cell's finite capacity to divide – a phenomenon known as replicative senescence – is an intrinsic feature of the body's cells and fundamental to the aging process. Telomeres in most human cells shorten during aging, suggesting that it is both a cause and a biomarker of aging.”

“Continued physical, social, and intellectual engagement offers a practical way to support multiple parts of peakspan throughout later life, while the framework helps people think about function one domain at a time.”

“In this clip, Drs. Levine and Patrick discuss how genes that are important for embryonic development can tell us a lot about aging. Dr. Levine gives her insights into the process of aging - is it the accumulation of random damage or the malfunction of a cellular program?”

“A systematic review in older adults linked Mediterranean dietary patterns with lower inflammatory markers, while a meta-analysis of randomized trials found that vitamin D supplementation reduced acute respiratory infection risk overall, with the strongest protection among people who were very deficient and received regular doses.”

“This serves as a distraction to sirtuins, however, ultimately drawing them away from their primary role. In the end, the cell experiences a sort of "identity crisis," unable to perform its original job, leading to aging.”

“This small study supports the idea that correcting low status can influence biological-aging markers, while larger and longer trials are needed to understand durability and clinical meaning. Brain-health evidence includes complementary study designs.”

“Over three years, omega-3 produced small favorable changes in three newer DNA-methylation aging measures: PCPhenoAge, GrimAge2, and DunedinPACE. Vitamin D and strength exercise did not change the clocks alone, but the full combination produced the largest result on PCPhenoAge, equivalent arithmetically to about 3.8 months over three years.”

“In fact, methylation and demethylation are critical processes in development. Interfering with the enzymes that carry out these two opposing processes can play critical roles in epigenetic age, ultimately affecting aging, disease, and death.”

“Although epigenetic clocks clearly relate to causal aspects of aging, scientists don't know if the clocks are inherently causal. At this time, the clocks are not validated for use as clinical biomarkers for individual use, but rather to look at trends across larger studies.”

Dr. Ben Bikman and Dr. Rhonda Patrick discuss fasting insulin, triglyceride-to-HDL ratio, uric acid, ApoB, and metabolic aging.
