Commonwealth Club of California Podcast

With so many conflicting and contradictory nutrition claims dominating headlines and social media, deciding what to eat has become unnecessarily complicated. Stanford nutrition scientist Christopher Gardner, Ph.D., has spent more than three decades conducting evidence-based research to bring clarity to the conversation. In this program, Gardner shares what decades of human nutrition trials reveal about where true scientific consensus exists, and where it does not. From his landmark “A to Z” and “DIETFITS” studies to ongoing research on plant-rich alternatives, ketogenic diets, the gut microbiome, and inflammation, Gardner has worked to move the field beyond diet myths and toward practical, evidence-based guidance. At the center of his message is a powerful idea: healthy eating can be “unapologetically delicious,” built around whole, minimally processed, plant-rich foods aligned with personal values around culture, sustainability and social responsibility. He will address pressing questions about different diets, cholesterol, seed oils, ultra-processed foods, protein, plant-based meats, fiber, fermented foods and more, offering a framework that helps individuals make informed, flexible, and lasting food choices. This conversation invites us to reconsider not only what we eat, but how we think about food: as nourishment, pleasure, culture and a powerful tool for long-term personal and planetary health. About the Speakers Christopher Gardner, Ph.D., is a professor of medicine at Stanford Prevention Research Center who has led more than 20 years of NIH-funded, randomized controlled trials on nutrition. His work focuses on diet patterns, weight loss and cardiometabolic health. A Nutrition, Food & Wellness Member-led Forum program.

More and more, conservative voices are making the case that the U.S. can’t achieve energy dominance without solar power. Even the leading industry trade group is changing its strategy. Earlier this year, ⁠Politico⁠ reported that the American Clean Power Association launched the “American Energy First” campaign to engage Kellyanne Conway and conservative influencers like Katie Miller “to amplify the benefits of solar energy” and “note the harm that could result from reckless trade policy.” Meanwhile, conservative groups at the state and federal level are advocating for building out solar power in service of private property rights, economic development and national security. Episode Guests: Kelsey Brugger, Congressional policy reporter, Politico Skyler Zunk, Executive Director, Energy Right; Executive Director, America First Energy Lillian Floutsis, Indiana Senior Field Representative, Indiana Land and Liberty, Conservative Energy Network This episode also features a reported piece from David Condos of KUER.

Martha Raddatz has seen the uncommon courage of service members and their families, and she has watched—in war zones and on the home front—as they have faced daunting odds and come out stronger. She asked veterans whose character and actions have impacted her deeply to relive their most challenging moments, so that others will know who they are and what they have done. In her new book The Hero Next Door, Emmy Award–winning ABC News journalist and bestselling author Martha Raddatz shares 10 stories of American warriors and their families, whose superhuman sacrifice and resilience—on and off the battlefield—show that true courage comes in many forms. She introduces readers to an air force rescue parajumper who put his life on the line to save a man whose fate would become entwined with his; a marine ambushed in Helmand whose life-changing injury forced him to take on a different kind of fight; a trailblazing F-18 fighter pilot flying missions over Syria; a combat surgeon who pioneered a new way of saving people with traumatic brain injuries and turned his world upside down to train doctors in Ukraine; an intelligence officer who forged a lifetime friendship with the man who saved him on 9/11; and two mothers whose love and sacrifices embody the ideal of selfless service. Some of these people were inspired to join the military by parents who served, and some left abusive families, determined to do better. Some joined when everyone was against it. They were there because they wanted to be part of something bigger than themselves. Raddatz says the qualities that made them shine on the battlefield gave them the strength to conceive of transformative second acts. The focus, mental resilience, and emotional fortitude kept them going through physical and emotional setbacks. They started companies to fill a need, created nimble nonprofits, and hunted for humor wherever they could find it. Most Americans don’t know these people. Join us as Martha Raddatz changes that.

The Goldman Environmental Prize is known as the Nobel for grassroots environmental champions, for good reason. Award-winners are earth defenders, often bucking entrenched systems and powerful interests in order to protect and restore the natural environments we all depend on. This week we feature conversations with two of the 2026 Goldman Prize winners: Iroro Tanshi, a tropical conservationist and bat ecologist who rediscovered a species that hadn't been seen in half a century. When climate-amplified wildfire threatened to destroy her new find, she built a community movement to virtually eliminate the wildfire risk. Sarah Finch, a tireless environmental advocate who spent years in English courts using planning law as a defense against the fossil fuel industry. She won a major UK Supreme Court ruling, a ruling that is already constraining oil, gas, and coal development across the country. What can we learn about passion, persistence, and collaboration from these two advocates? Guests: Iroro Tanshi, Tropical Conservationist Sarah Finch, Environmental Campaigner For show notes, related links, and episode transcript, visit https://climateone.org/podcasts Highlights: 00:00 Intro 03:01 Iroro Tanshi on Warri, Nigeria and the oil industry 05:37 Iroro Tanshi on becoming interested in bats and the forest 09:24 Iroro Tanshi on finding a bat species once thought extinct 14:03 Iroro Tanshi on when a wildfire tore through the research site 19:20 Iroro Tanshi on the wildfire risks of forests in equatorial Africa 20:50 Iroro Tanshi on working with the community to address the wildfires 23:01 Iroro Tanshi how to scale what she’s learned world-wide 24:40 Iroro Tanshi on what bats can teach people about being human 27:17 Sarah Finch on realizing the far reaching implication of her work 30:49 Sarah Finch on why the legal argument finally worked 34:42 Sarah Finch on getting the confidence to go after big oil 44:43 Sarah Finch on how a group of people can make a real difference ********** Support Climate One by going ad-free!

Much of what we call luck is the result of deliberate actions and consistent efforts. As Stanford Professor Tina Seelig shared in her popular TED Talk, luck is like the wind—constantly blowing, often unpredictable, and always in motion. To catch the winds of luck, she says you need to construct your sail by doing the internal work that sets the stage for success; recruit your crew by bringing others along; and hoist your sail by acting in ways that lead you closer to your goals. With these practical tools in hand, she says the winds of luck carry you toward the future you dream to live. Her new book What I Wish I Knew About Luck is filled with memorable examples, personal anecdotes, and behavioral science research. You will learn: how to stay steady in turbulent waters how to sail past your limits how to see problems as opportunities how to build ladders to larger wins how to clear clutter on your path to success how to turn setbacks into stepping stones how luck is amplified over the course of a lifetime With her expertise on leadership, entrepreneurship and innovation, Dr. Seelig shares her ideas on how to see and seize opportunities, especially those hidden in plain sight. Opportunities are everywhere, waiting to be discovered! Learn more about your ad choices. Visit megaphone.fm/adchoices

Protest is the ultimate in equal-opportunity political action. As Annie Leonard, former executive director of Greenpeace USA says, "Making change is like laying a stone path across the garden. Peaceful protest may be every 4th or 8th or 200th stone; it helps us get where we want to go but also we need a lot of other stones too.” Leonard explores the history of protests in her new book “Protest: Respect It. Defend It. Use It.” And while protest is the loudest and most visible tool, it’s only one of many ways to take action. Through community building, through civic engagement, through elected office, through corporate boardrooms, through churches and nonprofit agencies, there are countless paths to exercising power and promoting positive change. In this episode we hear from three leaders working in three different arenas, all toward the same goal. Guests: Annie Leonard, Environmental Activist, Author of “Protest: Respect It, Defend It, Use It” Danielle Lee, Founder, Climate Action Club James Coleman, City Councilor, South San Francisco For show notes, transcript, and related links, visit ⁠climateone.org/podcasts⁠ Highlights: 00:00 – Intro 04:00 – Annie Leonard shares the story of the Section 504 sit-ins protest in San Francisco 06:30 – Different ways protest can be effective 08:30 – Leonard on why she puts her body on the line (gets arrested) during protests 16:00 – Leonard on the lawsuit Energy Transfer brought against Greenpeace USA over Standing Rock protests 22:00 – Protecting, defending, and using the right to protest 26:00 – Danielle Lee on organizing younger people around climate and environment 30:30 – Systemic versus personal action 37:00 – James Coleman on the decision to run for office as a tool for effective change 41:00 – Impact of local government 46:30 – How change actually happens 50:00 – Climate One More Thing ********** Support Climate One by going ad-free!
