The Truth About Nutrition: Why Our Food System Isn’t Built to Keep You Healthy

from The School of Greatness · host Dr. Jessica Knurick, Lewis Howes

Dr. Jessica Knurick reveals a truth most nutrition experts won't admit: our food system is designed for profit, not health, and over half of American adults are living with chronic disease as a result. As a science-based dietitian who lost her grandfather to preventable illness at 60, she's spent her career fighting back against fear-mongering and misinformation that keeps people confused and sick. In this eye-opening conversation, she exposes why seed oils aren't the villain everyone claims, how ultra-processed foods hijack your brain to make you overeat 500 calories a day, and why the most effective health advice is actually boring. You'll walk away understanding that 90 percent of nutrition science is settled and simple, but social media algorithms profit from making you believe everything is controversial and complicated.Dr. Jessica Knurick on SubstackDr. Jessica Knurick on InstagramIn this episode you will:Discover why our food system is engineered for the majority of people to fail at health, not succeed, and how this affects every choice you makeUnderstand why over 90 percent of Americans fail to meet basic vegetable and fiber intake while chronic disease continues its relentless climbBreak through the seed oil controversy by learning what the actual research shows versus what social media wants you to believe for clicksTransform your family's relationship with food using the inclusion method that gets kids excited about nutrition without the good food bad food trapMaster the art of spotting nutrition misinformation by recognizing fear-based hooks and learning who actually deserves your trust onlineFor more information go to https://lewishowes.com/1845For more Greatness text PODCAST to +1 (614) 350-3960More SOG episodes we think you’ll love:Dr. Mark Hyman – greatness.lnk.to/1695SCDr. William Li  – greatness.lnk.to/1743SCGlucose Goddess – greatness.lnk.to/1575SC Get More From Lewis!
