#21 Selenium's Dual Role in Health & Aging in the Womb | Dr. Vadim Gladyshev

All platforms / Episode Show Notes: https://livelongerworld.substack.com/p/vgladyshev  Dr. Vadim Gladyshev is a professor at Harvard Medical school and a Director of redox medicine at Brigham and Women’s hospital, where he runs his own lab.  We had a brilliant discussion which started off by talking about his work on selenium. Selenium is found is Brazil nuts and we discussed its connection to aging and cancer prevention, and also some of the harmful effects it can have. Dr. Gladyshev calls it the good, the bad, the ugly nature of selenium.    Then, we discussed a fair bit on his theory of aging before and after development. Most people believe that the germline which is the reproductive cells do not age, but his lab’s work has shown how the germline does in fact age. On this point, his lab also has interesting results on how rapamycin during development extended lifespan in mice.   It’s important to understand the basic science and understand more on the aging process in order to crack it. Dr. Gladyshev shares his views on this too and his research is certainly a step towards cracking the aging code.

#18 Longevity Supplements - Interventions Testing Program Results | Dr. Richard Miller

Dr. Richard Miller runs one of the labs for the Interventions Testing Program or the ITP, which is largely considered the gold standard for testing longevity drugs. This was one of the best conversations I’ve had on longevity supplements that affect lifespan and those that might me subject to mere hype. Dr. Miller is rigorous in his approach and states the data clearly. He also has opinions on lifespan vs. healthspan that are unique from those of most others and worth paying attention to. I genuinely walked away having learned so much from this conversation and feeling more awakened, and I hope it is useful to you too in parsing the data out there on longevity supplements.   In today’s episode, you will learn:  - The 4 winning drugs that increase lifespan in mice as tested by the ITP: Rapamycin, Acarbose, 17-alpha estradiol, Canagliflozin  - 3 other drugs that produce small lifespan benefits: NDGA, Glycine, Captopril  - Drug combinations: Rapamycin + Acarbose, Rapamycin + Metformin  - Drugs that show no lifespan increase in mice in the ITP: Resveratrol, Nicotinamide-Riboside (NR), Fisetin, Curcumin, MCT Oil, Green tea extract, Fish Oil + more  - Richard’s thoughts on lifespan vs. healthspan   All platforms / Episode Show Notes / Timestamps: https://livelongerworld.substack.com/p/rmiller  Find the previous podcast episodes & subscribe to be notified: https://www.livelongerworld.com/podcast  Sign up for Premium Subscriber Summarized Show Notes: https://www.livelongerworld.com/premium  Support on Patreon: https://www.patreon.com/livelongerworld One-Time support: https://www.paypal.com/paypalme/livelongerworld  RICHARD MILLER LINKS:  Website: http://www.richmillerlab.com/ Photography: https://richardmiller.zenfolio.com/ Interventions Testing Program: https://www.nia.nih.gov/research/dab/interventions-testing-program-itp  LIVE LONGER WORLD LINKS:  Website: https://www.livelongerworld.com/ Twitter: https://twitter.com/livelongerworld Newsletter: https://livelongerworld.substack.com/ Instagram: https://www.instagram.com/longevityfuture/ Patreon: https://www.patreon.com/livelongerworld YouTube: https://www.youtube.com/c/LiveLongerWorld Premium Subscriber: https://www.livelongerworld.com/premium TIMESTAMPS:  0:55 Richard Miller Intro  1:51 Richard Miller Wildlife photography  3:30 ITP - the gold standard for testing longevity drugs & winning drugs  10:51 Rapamycin, Rapamycin + Acarbose  18:48 Rapamycin + Acarbose Dosing Schedule  20:15 Combination of drugs, Rapamycin + Metformin  21:56 17-Alpha Estradiol  25:45 Canagaflozin  31:34 Does Richard take the 4 winning drugs?  32:46 3 Drugs that have small lifespan effects & promising  36:30 GPLD-1 & shared mechanisms in longevity drugs  44:04 Resveratrol in ITP  46:27 NR, NMN  52:34 Curcumin, Green Tea Extract, MCT Oil  54:54 Fisetin & Senolytics  56:12 Why most published research findings are false  1:00:03 Healthspan biomarkers at the ITP  1:02:38 Can you have healthspan without lifespan?  1:07:37 Fish Oil, Spermidine, Sulforophane  1:12:13 Unpublished data Richard is excited about  1:17:47 Flying Pigs & Aubrey De Grey  1:20:00 Exponential rise in aging research Episode Show Notes: https://livelongerworld.substack.com/p/rmiller Thanks for listening & if you enjoy the episode, let's spread the message on longevity.

#13 Dr. David Gems | Hyperfunction & Programmatic Theory of Aging and Critique of the Hallmarks of Aging

My guest today is Dr. David Gems who runs the C. Elegans Aging lab at the University College London. We had a fascinating discussion talking about emerging paradigms in the theories of aging. We discussed the hyperfunction theory or the programmatic theory of aging which gives a better integrated understanding of the different theories of aging that have been presented such as damage accumulation, evolutionary, antagonistic pleiotropy. It has been assumed that molecular damage is always the cause of aging, but the programmatic theory of aging shows that that might not be the case. We also discussed his critique of the hallmarks of aging and how there should be a better paradigm for the aging field. Lastly, we also discussed how research from his lab on C. Elegans might explain some of the conflict around whether sirtuins affect lifespan and how C. Elegans also show versions of this programmatic theory of aging, which can give us a better understanding of how to study aging. Note: There is a point in the conversation (40:41) where David pulls up some slides to better explain the Multifactorial Model of Aging. So if you are listening to the audio version, you might want to refer to YouTube or the show notes.

#12 Dr. Bruce Ames | Longevity Micronutrients, Triage Theory, and Vitamin D for Healthy Aging

My guest today is Dr. Bruce Ames who has received several awards and accolades for developing the Ames test which is used to detect carcinogens in commercial products. He showed how there were carcinogens in products such as hair dyes and children’s pajamas!    Later, Dr. Bruce Ames turned to studying micronutrients and how deficiency of important vitamins and minerals leads to accelerated aging. He came up with the Micronutrient triage theory, which says that when nutrient intake is insufficient, the body has a rationing mechanism and favors proteins needed for immediate survival at the expense of protection against future damage.    Dr. Bruce Ames is 93 years old and says that he is still exercising and eating healthy greens cooked by his lovely Italian wife! However, he says his cognitive capacity has slowed down (this is why we need rejuvenation therapies, even for the brain: listen to my episode with Dr. Jean Hebert who talks about Brain Aging and his strategy to reverse aging through replacement of the body parts: https://youtu.be/oerGUepWsH8).   I am grateful that I had a chance to converse with him on Vitamin D, longevity micronutrients, how micronutrient deficiency can lead to accelerated aging, his take on the science behind reversing aging, and his advice to younger people.    This is a shorter episode and I hope you learn more about the importance of micronutrients!   All platforms / Episode Show Notes: https://livelongerworld.substack.com/p/bames   RELATED WRITING:  My newsletter post explaining the Micronutrient Triage theory: https://livelongerworld.substack.com/p/bruceames  My post on Longevity Foods (Nutrition Doesn't have to be so complicated): https://livelongerworld.substack.com/p/longevityfoods   Sign up for Premium Subscriber Extensive Show Notes & Transcripts: https://www.livelongerworld.com/premium  Find the previous podcast episodes & subscribe to be notified: https://www.livelongerworld.com/podcast  Find me on Twitter: https://twitter.com/livelongerworld Support on Patreon: https://www.patreon.com/livelongerworld  DR.
