The Perfect Gut Healing Protocol: What to Eat, Avoid, and Do Every Day

**Dr. Mark Hyman** (0:00)
What if brain fog, anxiety, and mood swings aren't simply all in your head? What if the health of your mind actually starts deeper in your body, in your gut, in your hormones, metabolism, and your immune system? Well, let me tell you, the connection is real, and it affects how you think and you feel every single day. And that's why I created Brain Shaping Academy, a six-week program that shows you how healing your body can help you heal your mind. Brain Shaping Academy relies on the same target nutrition and lifestyle strategies I've used for 30 years to help my patients improve their mental, emotional, and cognitive health. So if you want to feel calmer, clearer, and more in control, and stay sharp and protect your brain as you age, check out Brain Shaping Academy at drhyman.com/brainshaping.

Because at the end of the day, you are the CEO of your own health. And for many of you, your family's health too. And you might not feel it all the time, but you have far more power and agency than you realize. I'm glad you're here.

Bloating, fatigue, brain fog, skin issues, food sensitivities, anxiety, autoimmune disease. Well, most people don't realize these problems all trace back to the same place, the gut.
I'm not just talking about digestion. In functional medicine, we often see the gut as one of the central control systems for overall health because it influences nearly every major system in the body. Your gut affects your immune system, inflammation, hormones, metabolism, nutrient absorption, even brain health and mood. In fact, about 70% of your immune system lives in and around the gut. And the trillions of microbes living inside your digestive system, what we call the gut microbiome, well, they play a major role in regulating inflammation, metabolism, cravings, mood and so much more.
And here's what many people miss. You don't need to have obvious digestive symptoms to have gut dysfunction.
Some people have bloating or reflux, but for others, it may show up as fatigue or skin problems or joint pain or brain fog or hormone imbalance or autoimmune symptoms or just feeling inflamed all the time without understanding why.
That's because when the gut becomes unhealthy, the effects can ripple throughout the entire body. Now, the good news is this. The gut is incredibly dynamic and capable of healing when we create the right condition. So today, we're talking about how to actually begin healing your gut. What damages it, what restores it, and the foundational steps that make the biggest difference. And more importantly, we're going to keep this practical. We're going to keep it realistic. It's not about buying a dozen supplements or following some extreme protocols. It's about understanding the basics that truly move the needle when it comes to the gut and your gut health and your overall health. One of the biggest shifts happening in medicine right now is the growing understanding that the gut isn't just about digestion. The gut is deeply connected to almost every aspect of health. In functional medicine, we often start with the gut because when the gut is unhealthy, it can get ripple effects throughout the entire body. There's a reason for that. About 70% of the immune system is in and around the gut. Every day, your digestive system is acting as major communication center between the outside world and your immune system. Your gut is constantly deciding what gets absorbed, what gets blocked, what's safe, what might be a threat. At the same time, the gut is in constant communication with the brain through what we call the gut-brain axis. This means your digestive system and your nervous system are constantly influencing each other. So when people experience stress-related digestive issues, anxiety alongside their gut symptoms, brain fog, mood changes, cravings, these things are often connected more than people realize. And then there's the microbiome, the trillions of bacteria, fungi, microbes that live primarily in your intestines. These microbes are not passive. They influence inflammation, mood, metabolism, cravings, skin health, hormone balance, immune function, even how we process nutrients and toxins. You're not just feeding yourself, you're feeding trillions of microbes that influence your health every day. The quality of that internal ecosystem matters enormously. A healthy gut is really a balanced, resilient ecosystem. You want healthy microbial diversity, strong digestion, healthy gut lining, balanced immune signaling, and effective absorption of nutrients. But when that ecosystem becomes disrupted, well, through processed food, through stress, through antibiotics, infections, lack of sleep, environmental toxins, inflammation, well, the consequences extend far beyond the digestive tract. We can begin to see chronic inflammation, increased intestinal permeability, sometimes we call leaky gut, immune dysfunction, nutrient deficiencies, food sensitivities, fatigue, skin issues, hormone imbalance, chronic symptoms that don't always seem obviously connected to digestion.
