about me
Hi, I’m Yvonne Mullan—Registered Dietitian, Certified Diabetes Educator, Integrative and Functional Nutrition Certified Practitioner, a Mom and a proud neurodivergent woman.
With over 20 years of experience in clinical nutrition, I’ve supported people living with type 1 and type 2 diabetes, chronic conditions, and complex health stories. I’ve worked in academic teaching hospitals and community care, and I stay up to date with the latest nutrition research.
But my most transformative learning came from a much more personal
place—my daughter. When she was diagnosed with ADHD and autism, it opened a new chapter in our lives. As I navigated the healthcare system, therapies, and nutrition strategies to support her, I began to recognize many of the same traits in myself. Eventually, I was diagnosed with ADHD too.
That moment changed everything.
I suddenly understood, on a deeply personal level, the challenges that neurodivergent people face: the executive function hurdles, the brain fog, the decision fatigue, the sensory sensitivities, the overwhelm. I also understood how traditional healthcare often misses the mark—how it can feel rigid, judgmental, and not built for brains like ours.
That’s why I created Spicy Brain Nutrition—a space where neurodivergent individuals, especially girls and women, can feel seen, heard, and supported. Whether you’re navigating adolescence, pregnancy, menopause, or aging, or parenting a neurodivergent child, I’ve been there.
​
I get it.
​
And I’m here to help.
​
I believe in:
- Evidence-based care grounded in the latest research
- Root-cause exploration through integrative and functional nutrition
- Holistic healing that honors body, mind, and spirit
- Neuro-affirming support that’s non-judgmental and inclusive
- Collaboration with both traditional and alternative care providers
- Empowering you to trust your intuition and write your own health story
I’m not here to hand you a rigid plan. I’m here to listen, guide, and co-create strategies that are realistic, meaningful, and sustainable for you. You are the expert of your own
experience. I’m just here to help you make sense of it—and nourish it.
