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.
