Can’t make it live? Register anyway for the recording. But trust me, the Q&A is where the magic happens.
I’ve spent years watching people struggle with their mental health while completely ignoring what they put on their plates. This isn’t alternative medicine—it’s basic neuroscience that somehow got left out of most mental health conversations.
Let’s connect the dots between the DBT skills you might already know and the nutrition piece that has been missing. Because radical acceptance includes accepting that what you eat directly impacts how you think and feel. And building a life worth living? That starts with feeding your brain what it needs to thrive.
Wise Mind Nutrition is not another diet. It’s using the same skills that help you navigate emotions to navigate your kitchen. Ready to upgrade your mental health toolkit?

I’ve always known that beans, nuts, and seeds were the jewels of the food supply. That’s why I created a food group for them. Nuts and seeds are unique because of their fatty acid profiles and their abundant minerals.
When I’m eating nuts and seeds everyday, it usually indicates that things are going well in my life.
What’s your favorite nut or seed?

📊 This systematic analysis reviewed multiple studies following hundreds of thousands of participants to understand how food processing affects brain health and mental well-being.
🔬 The research reveals clear biological pathways connecting ultra-processed food consumption to increased risks of depression, anxiety, and cognitive decline - but also shows these effects can be modified through dietary changes! 💪

🧠 Nutrition is the missing link in mental health care.
Most people don’t realize that what we eat directly impacts how we feel—emotionally, cognitively, and behaviorally.
Here, I discuss science-backed nutrition strategies for supporting your brain and mood.
These aren’t “quick fixes”—they’re foundational tools for long-term resilience.
🍊 Vitamins
🥬 Minerals
🥑 Healthy fats
🧠 And yes, even your gut microbes…
Food is mood information.
If you’re looking to optimize your mental health, reduce symptoms of anxiety or depression, and take a whole-person approach to wellbeing, start with what’s on your plate.
