Shane Parrish sits down with the renowned biochemist Dr. Rhonda Patrick to explore the intricate world of nutrition and health. Dr. Patrick provides a deep dive into the role micronutrients play in our daily health, detailing how deficiencies and insufficiencies in vitamins, minerals, fatty acids, and amino acids can lead to serious health issues over time. Shane and Dr. Patrick also discuss the science behind deliberate heat exposure. She outlines the optimal sauna conditions—temperature, duration, and frequency—necessary to achieve these health benefits and explains the physiological mechanisms at play.   Rhonda Patrick has a Ph.D. in biomedical science and a Bachelor of Science degree in biochemistry/chemistry from the University of California, San Diego. She has done extensive research on aging, cancer, and nutrition.   (00:00) Intro (04:40) A philosophy for nutrition (15:36) Micronutrients through supplements vs. food (25:43) Wild-caught vs. farm-raised fish (28:44) Organic vs. non-organic vegetables (36:14) On macronutrients (40:20) How protein levels differ in different foods (45:27) The best morning smoothie recipe (54:48) Dr. Patrick grades Shane's "GOAT" smoothie recipe (59:14) Grass-fed vs. non-grass fed (01:04:40) On vitamin D (Is sunscreen killing us more than the sun?)
