Sanity Before Vanity: Nutrition as Mental Health Medicine with Dr. David Wiss

Have you ever thought nutrition was just about managing weight? Think again. In this episode of The Gaslit Truth Podcast, mental health nutritionist Dr. David Wiss exposes how the food industry has misled us into obsessing over calories while ignoring the quality of what we eat—and its impact on mental health. Drawing from his experience as a dietitian turned whistleblower, Dr. Wiss reveals industry-funded misinformation and how ultra-processed foods contribute to emotional struggles like anxiety, depression, and addiction. He champions a functional medicine approach that connects nutrition to mental, physical, and even spiritual well-being by looking at the full picture of a person’s life. His message is clear: “Sanity before vanity.” Instead of focusing on appearance, he urges us to use food to support emotional resilience and brain health. For a deeper dive, his “Wise Mind Nutrition” app offers a holistic, non-diet-based path to true nourishment—because your mental health deserves more than calorie math.
