The Anxiety–Gut Connection: How Stress, Food, and the Nervous System Shape Mental Health
Stress isn’t just something you feel—it’s a biological process that affects your brain, gut, hormones, and metabolism. Over time, chronic stress can shape how we eat, how we feel, how we heal, and how resilient our bodies are.
In this webinar, Dr. David Wiss, PhD, RDN, IFMCP, will help demystify the biology of stress in clear, accessible terms—and, most importantly, focus on what actually helps. Designed for cancer survivors, caregivers, and anyone navigating ongoing stress, this session balances science with practical, compassionate guidance you can apply in daily life.
Together, we’ll explore:
- How stress works in the body, and simple ways to support regulation and resilience
- The two-way connection between stress and gut health
- Why stress eating is a biological response, not a failure of willpower
- How chronic stress affects the nervous system and contributes to burnout
This session will emphasize small, realistic steps that support the nervous system and overall well-being.
