NEW RESEARCH ALERT! 🚨
I’m excited to share our latest study published in Frontier in Psychiatry examining how childhood adversity impacts our relationship with ultra-processed foods 🍕🍩🍟
Our findings suggest that people with 4+ adverse childhood experiences (ACEs) have DOUBLE the odds of developing ultra-processed food addiction (UPFA). And for those with a history of substance use disorder (SUD), this risk is even greater! 📈
This research highlights why we need trauma-informed approaches in nutrition counseling and addiction treatment. It’s not just about willpower—our early experiences shape our brains’ responses to highly rewarding foods.

My first walk was 60 miles in 2008 with @ryrongracie and a crew of athletes. I will never forget it.
From that experience, I brought the concept of “night walking” or “meditation walking” to my sober community. We used to walk from 2:30am-7am to catch an additional buzz from sleep deprivation.
Eventually, we started walking earlier so that people in treatment centers could join us.
I started doing walks with @beittshuvah, and from that, we started the Running4Recovery marathon program. I walked five marathons with the Beit T’shuvah team and now provide some nutrition coaching to the team each year.
I have done the 14-mile walk along the bike path from Hermosa Pier to Santa Monica Pier about 50 times, but every walk is unique.
Last night was particularly special. We struggled, chatted, synchronized our movement to our breath, and demonstrated our commitment to a spiritual way of life.
Big shout out to @itslianarae @kourtney.golden @foruitousebb9911 @japkets @karenjayres @untamedstar16 and everyone else who joined us!
I am in awe of the Power.

We had a sick baby recently, and the pediatrician sent my wife home with Pedialyte, which was red. I already knew what we were up against…
🌈 While Red Dye 40 in Pedialyte isn’t necessarily dangerous for most people, it does make us question why we need artificial colors in products meant to help us heal.
Is it for us or purely marketing?
Have you ever thought about the dyes in your children’s medicine? Is it absolutely necessary?

Is chia seed water everything that the internet claims? There’s truth behind the trend! 💦
I love using chia seeds as part of a gut-healthy eating pattern. The fiber in chia seeds (nearly 10g in 2 tablespoons!) can help with constipation and bloating - whether you consume them in water or another way.
The key benefits:
✓ Contains both soluble and insoluble fiber
✓ Expands and forms a gel-like substance that helps digestion
✓ Helps you feel full and satisfied
✓ Supports gut health (which connects to brain health!)
Remember: soaking them first prevents uncomfortable bloating.
My recommendation: Start with one tablespoon daily soaked in water (or added to smoothies, oatmeal, or yogurt) and gradually increase as your body adjusts.
Make it part of your daily routine!
Some people choose to consume in the evening time…(after dinner)
How do you like to consume chia seeds? Drop a comment below! 👇

🚨It’s time we have an honest conversation about calories.
For years, my field has been trapped in a reductive mindset that boils nutrition down to a single number. But what if I told you that calorie counting is not just ineffective—it’s potentially harmful?
Throughout my entire career, I’ve known that calories are deeply misleading. They force us to see nutrition through a narrow lens, overlooking the profound complexity of how food interacts with our body.
Instead of obsessing over numbers, I want to shift our focus:
* Quality over quantity
* Whole foods over processed
* How food makes you FEEL
* The deeper signaling information of nutrition
* The symbolic meaning of connecting with food
This isn’t just about weight—it’s about holistic health, mental wellness, and truly understanding our relationship with food.
Ready to break free from the calorie-counting trap?

🍎 MAJOR NEWS: RFK Jr. is taking on food safety regulation to protect our health! 🍎
Secretary Kennedy just directed the FDA to close a major loophole that allowed food companies to add new ingredients without notification or safety review 💯
This change would make it mandatory for companies to publicly notify the FDA and submit safety data before adding new ingredients to our food supply 🔍
Part of a broader effort to address chronic illness and increase food transparency, including the recent proposal for front-of-package nutrition labels 🏷️
It’s about time someone prioritized transparency in our food system! This is what accountability looks like 👏
Who else thinks we deserve to know what’s in our food?
Drop a ❤️ if you support better food ingredient oversight!

🧠🥗 FINDING THE SWEET SPOT IN NUTRITION & MENTAL HEALTH
Ever notice how too many rules eventually lead to rebellion while complete lack of structure creates chaos? There’s a better way!
Nutrition for mental health isn’t about rigid rules OR complete freedom—it’s about finding that sweet spot of guiding principles that support your wellbeing while allowing flexibility.
As we teach in @wisemindnutrition: “Rules appear to be very much pass/fail whereas principles introduce more nuance and interpretation, embracing growth and evolution over time.”
If you haven’t tried setting some intentions and food logging in Wise Mind Nutrition, now is the time.
Remember: “Consistency with food leads to consistency with life” but this doesn’t mean perfection. It means developing sustainable patterns that nourish both body AND mind.
💬 What’s one balanced nutrition principle that works for YOU?
