Want to Stay Sharp As You Age?
It Starts With Your Gut.
Up to 80% of Alzheimer’s, stroke, and depression diagnoses can be prevented when you take the right steps early.
This all-access bundle gives you a doctor’s perspective on things like:
- Why your brain “hits the brakes” as you age (and how to flip it back on)
- What to do if Alzheimer's or Dementia run in your family — and why these diseases are NOT your fate
- The brain-saving foods you should pile on your plate, and the “healthy” ones that secretly speed decline
- What’s really behind the mood swings and energy dips most people blame on aging
- And why your diet and exercise habits are just a SMALL piece of the brain health puzzle!
“Dr. Nandi tackles the complexity of the intersection of our mind, spirit, and body with a formula and recipes that bring his expertly informed philosophy to your daily life and straight to your dining table…”
-David T. Rubin, M.D., Professor of Medicine, Chief, Section of Gastroenterology, Hepatology and Nutrition at University of Chicago
As SEEN IN...
My Father's Sudden Stroke Changed Everything I Thought I Knew About the Brain....
…Now I'm giving you the tools to protect your health before it’s too late.
Hi, my name is
Dr. Partha Nandi.
For 20+ years, I’ve been a practicing gastroenterologist and host of Ask Dr. Nandi — a show that’s aired in 95 million homes across 7 networks and over 80 countries.
But none of that is why I’m here.
In 2007, my father — my hero, my role model, and the smartest man I knew — collapsed from a massive stroke.
We rushed him to the hospital, and the doctors ran every test. Every scan. Every lab.
...And everything came back “normal.”
They had no answer as to why a seemingly healthy person had just suffered a massive, life-altering stroke.
After that night, I realized how little even we doctors truly understood about the brain and why it fails.
It sent me down a 15-year rabbit hole to uncover what the scans and pills were missing.
What I found changed everything about how I practice medicine…
…and it’s what I’m going to share with you here today.
These are just a few of the lies we’ve been told about our brain and mental health:
- Forgetting names, losing focus, and feeling mentally foggy is just part of “getting older”
- Anxiety and depression are “chemical imbalances” in the brain, and medication is the only fix
- Mood swings are "just hormonal" — especially if you're a woman
- And the list goes on…
These outdated beliefs are still being taught in med schools and passed from doctor to patient every day.
And they’re not just wrong… they’re dangerous.
The truth is, those ‘normal’ symptoms aren’t normal at all — they’re early signs brain decline has already started in your gut.
Your gut and your brain are on a direct line through the vagus nerve…
And your gut does most of the talking.
So when you feel foggy… when your mood crashes… when your energy tanks…
That’s not aging…
That’s your gut sending distress signals.
Your Gut and Your Brain Are in Constant Communication...
In fact, your gut sends 10x more signals to your brain than the other way around.
That’s why gut issues like bloating, inflammation, or bad bacteria can show up first as:
- Brain fog
- Anxiety or irritability
- Low energy or motivation
- Trouble focusing
- Mood swings
Your gut also produces the very chemicals your brain needs to function. We’re talking about:
90% of your serotonin
(your “feel good” neurotransmitter)
50% of your dopamine
(your motivation and reward chemical)
GABA
(the calming chemical that helps reduce anxiety)
Gut Problem
Brain Effect
Bad gut bacteria
Anxiety, mood swings
Poor digestion
Brain fog, low energy
Processed food and sugar
Depression, inflammation
Leaky gut
Autoimmune disorders, memory problems
Stress and lack of sleep
Indigestion, bloating
-
Certain gut bacteria can manipulate your mood, memory, and even trigger panic
attacks—without you ever knowing they’re there - That “healthy” food you’re eating? It could be worsening inflammation in your brain thanks to a hidden compound called neuropoison
- The gut doesn’t just “talk” to the brain—it sends out 10x more signals than it receives, acting as your real command center for mental health
- Bloating can trigger neuroinflammation that silently rewires your brain toward anxiety, depression, and even suicidal thoughts
- 1 in 3 people with cognitive decline don’t have any traditional brain symptoms first—they start with gut-related issues like IBS, bloating, or food intolerances
- And researchers now believe your gut bacteria may influence how quickly your brain ages—meaning the speed of cognitive decline could be dramatically slowed… or accelerated
There’s plenty more where that came from…
And it all flies in the face of what most of us have been told about brain health, our genetics, and our fate as we age.
So What Does This Mean for You—Right Now, Today?
For one, it means you have a right to be concerned about yourself and your loved ones…
And it also means the symptoms you’re feeling aren’t random.
Even small changes in your gut health can lead to immediate discomfort, both mentally and physically.
Fortunately, the reverse is true, too…
In one study from the Journal of Psychiatric Research, participants who followed a gut-supportive diet saw significant reductions in depression symptoms in just 3 weeks—without any changes to their medication.
Another study published in Frontiers in Neuroscience found that gut-friendly interventions (like probiotics and prebiotics) not only improved emotional resilience…
But also helped reduce cortisol, the body’s main stress hormone.
Translation?
Your brain is listening to your gut right now. And when you support it—even a little—it responds.
So, How Do You Save Your Brain?
First, you must understand that there isn’t one “magic diet” or “magic pill” that changes everything.
The reality is, your gut is affected by nearly every aspect of your life.
Your habits. Your thoughts. Your environment. Even your relationships.
That’s why Heal Your Gut, Save Your Brain isn’t just a diet book—it’s a daily blueprint.
Inside, I’ll show you how five key pillars are silently shaping your microbiome—and how to shift them in your favor.
The Five Pillars of Gut-Brain Health Inside of Heal Your Gut, Save Your Brain
Pillar 1: Purpose-Driven Living
Believe it or not, living without a sense of meaning increases gut inflammation and weakens the gut lining.
That’s because a lack of purpose puts the body into a low-grade stress response—flooding it with cortisol, disrupting digestion, and throwing off microbial balance.
I’ll show you how to identify the motivators that keep your nervous system regulated, and how even small shifts in purpose can rebalance your gut-brain axis.
You’ll also learn:
- Why chronic stress makes your microbiome more fragile—and how purpose helps reverse it (research shows that people with a strong sense of purpose have lower levels of inflammatory markers like IL-6 and CRP)
- The gut-hormone loop no one talks about (hint: cortisol is only the beginning—dopamine and serotonin play a key role, too)
- How to rewire your nervous system through values-based action—even in chaos
Pillar 2: Food and Nutrition
We both know you don’t need another trendy diet. Instead, you need to understand how food shapes your gut—and by extension, your mind. I’ll walk you through how common ingredients (even so-called “health” foods) feed the wrong bacteria, drive neuroinflammation, and throw off critical brain chemicals.
You’ll also learn:
- What to eat (and what to avoid) to support neurotransmitter balance and mood regulation
- How food additives like emulsifiers and preservatives silently damage the gut lining
- Why ancient practices like fermentation deliver a trifecta of prebiotics, probiotics, and postbiotics—and how to use them at home with simple recipes
Pillar 3: Meaningful Movement
Don’t like intense workouts? Great— you don’t need them! You’ll discover how strategic, intentional movement enhances gut motility, reduces cortisol, and boosts dopamine levels—without needing to hit the gym for hours.
You’ll also learn:
- The type of movement shown to increase beneficial bacteria like Akkermansia muciniphila in just one week
- Why overexercising can harm your gut (and what to do instead)
- A 10-minute daily ritual to improve vagal tone and optimize the gut-brain connection
Pillar 4: Relationships
This is potentially the most overlooked aspect of gut health and brain health. The truth is, your relationships are as vital to your gut as your diet. Studies show that social isolation disrupts gut flora and increases disease risk—while meaningful connection boosts resilience, immunity, and emotional health.
You’ll also learn:
- How loneliness increases intestinal permeability (aka “leaky gut”)
- Why emotional safety changes the composition of your microbiome
- How to build “gut-safe” relationships—even if your current circle isn’t there yet
Pillar 5: Spirituality
Having a spiritual practice—regardless of whether it’s “religious” or not—is actually a powerful biological tool for reducing inflammation, balancing neurotransmitters, and calming the nervous system. Whether it’s prayer, mindfulness, nature, or breathwork, I’ll help you find what works for you. No dogma, no pressure!
You’ll also learn:
- How spiritual practice influences serotonin and GABA production in the gut
- Why inner stillness improves microbial diversity and gut lining integrity
- The brain-gut benefits of my personal daily rituals—and how to start your own
Plus, Dig Into Recipes Designed to Reduce Stroke Risk, Improve Brain Function, and Ease Depression

- Brain-Boosting Fish Fillets

Are You Ready to Take Control of Your Brain Health?
The truth is, your body was never designed to survive this world as it is today.
Tens of thousands of chemicals—over 80,000—have been introduced into our air, food, and water. Most have never been properly tested for long-term safety.
We’re sleeping less, stressing more, and surrounded by ultra-processed foods that hijack our gut and damage the very systems meant to protect our brain.
It’s no wonder rates of Alzheimer’s, anxiety, stroke, and depression are rising fast—many of them linked to inflammation that begins in the gut.
But you can intervene.
This is for you if…
- You’ve been told your labs are “normal,” but you don’t feel like yourself anymore
- You have a family history of Alzheimer’s, Parkinson’s, or stroke—and you want to do everything you can to prevent it
- You feel tired, foggy, or anxious more days than not
- You’re sick of wellness fads and want real, evidence-based guidance from a practicing MD
- You want to make smarter choices—without turning your life upside down
- You want your brain to be sharp, your body resilient, and your energy steady as you age
This isn’t about doing everything perfectly.
It’s about knowing what really works—so you can finally take action, protect your brain, and feel better now.
