On this episode of Longevity by Design, Ashley Reaver, MS, RD, CSSD, and Dr. Gil Blander, delve into the intricate world of the immune system and its impact on aging with Dr. David Furman, Associate Professor at the Buck Institute for Research on Aging. David discusses his groundbreaking research on inflammaging— uncovering how chronic, low-grade inflammation can accelerate the aging process. Discover how David's team developed a new inflammatory age test, soon to be available from his company Edifice Health, that uses five key proteins to assess an individual's inflammatory state and predict future health risks. We also explore the surprising link between space travel and accelerated aging, examining the impact of microgravity on the body. Tune in to learn practical tips on combating inflammation and promoting longevity through lifestyle choices and a deeper understanding of your own personal health data.Episode highlights:Introduction: 00:00:00Why have you decided to be a scientist and not a painter: 00:04:001000 Immunomes: 00:06:00What is the immune system: 00:16:00Biomarkers related to the immune system: 00:18:00The development of frailty during the aging process: 00:21:00what inflammation is: 00:27:00Lifestlye dependent chronic stress: 00:31:00Inflammation-related biological clock: 00:34:00Epigenetic age: 00:38:00Centenarians and inflammatory markers: 00:48:00Space flight and inflammation: 00:51:00Astronauts aging: 00:55:00Microgravity as a stressor: 00:59:00Future of David's work: 01:04:00Summary: 01:06:00Not All Biological Age Clocks Are Created EqualWhile various biological age clocks exist, including epigenetic and glycan clocks, David's research highlights the benefits of protein-based clocks like his inflammatory age test. Unlike other clocks that closely correlate with chronological age, inflammatory age reveals more about an individual's biological state and potential health risks, offering valuable insights beyond simply reflecting the passage of time. Additionally, understanding how specific proteins link to inflammation allows for actionable lifestyle and dietary changes to positively impact those markers and potentially slow down the aging process. Lifestyle Choices Directly Impact Our Inflammatory LevelsMany modern lifestyle factors, often a far cry from our evolutionary past, contribute to chronic inflammation. These include exposure to environmental toxins like plastics and pesticides, poor sleep quality, disruptions to our circadian rhythm, social isolation, and chronic stress. By minimizing these exposome factors and adopting healthier habits—such as consuming whole foods, prioritizing sleep hygiene, and managing stress—we can potentially lower inflammation and support healthier aging. Space Travel Offers a Unique Perspective on Accelerated AgingAstronauts, despite being otherwise healthy individuals, experience accelerated aging due to the stressors of space travel, particularly the effects of microgravity. This provides valuable data on aging mechanisms that can be applied to Earth-bound research. By studying the physiological changes astronauts undergo, scientists can gain a deeper understanding of aging processes and potentially develop interventions to mitigate age-related decline for everyone. For science-backed ways to live a healthier longer life, download InsideTracker's Top 5 biomarkers for longevity eBook at insidetracker.com/podcast
