Dr. Don Colbert – If you find yourself feeling mentally sluggish during the summer months—struggling with memory, focus, or motivation—you’re not alone. Many of my patients describe what they call “summer brain fog.” And while you might blame it on the heat or disrupted routines, there’s often a deeper root: your gut. In this article, I want to unpack the fascinating link between gut health and brain function, and why healing your gut might be the most effective way to sharpen your mind—especially this time of year. We’ll also look at what science has to say, and how Scripture reinforces the importance of caring for our bodies with wisdom and intentionality. The Gut-Brain Connection: More Than a Feeling The gut and brain are connected by a complex network of nerves, biochemicals, and messenger systems known as the gut-brain axis. This communicationToxic Summer: Hidden Chemicals in Sunscreen, Swimsuits, and Bug Spray — And What God Says About Stewarding Your Body highway allows your digestive system to send and receive signals to and from your brain—often influencing mood, focus, memory, and even sleep. Here’s what we know from science: The gut produces over 90% of the body’s serotonin, a neurotransmitter crucial for mood regulation. An imbalance in the gut microbiome—such as an overgrowth of bad bacteria or yeast—can trigger inflammation, which can cross the blood-brain barrier and contribute to brain fog, anxiety, and fatigue. Studies show that gut dysbiosis (imbalanced bacteria) is associated with cognitive decline and poor memory. When the gut is struggling, the brain often suffers quietly until symptoms like fatigue, poor concentration, or forgetfulness emerge. Why Summer Makes It Worse There are several seasonal habits that may quietly sabotage gut health during the summer: 1. Processed Summer Treats Ice cream, BBQ sauces loaded with sugar, soda, and artificial dyes—these common indulgences can feed harmful gut bacteria and promote systemic inflammation. 2. Travel & Disruption of Routine Whether it’s international travel or a simple road trip, your digestion can be thrown off by irregular meals, different water sources, or unfamiliar foods. 3. Alcohol & Dehydration Increased alcohol intake and reduced hydration in the heat can irritate the gut lining and impair healthy digestion. 4. Sleep Disturbance Longer days and more activity can interfere with restful sleep, which your gut (and brain) need for repair and detox. What You Can Do to Restore Clarity If you want to reclaim your mental edge this summer, healing your gut is an excellent place to start. Here are a few simple yet powerful steps: 1. Cut the Sugar and Processed Foods Sugar feeds the wrong bacteria. Swap sugary snacks for high-fiber fruits like berries, which also support digestion and reduce inflammation. 2. Rebuild with Probiotics and Fiber Adding a quality probiotic and a soluble fiber supplement helps repopulate good bacteria and keep your gut regular. I often recommend Zone Biotics Probiotic and Fiber Zone from Divine Health. 3. Consider Advanced Gut Support For those needing more comprehensive care, Biotic Zone Probiotic is an advanced formula that combines powerful probiotics and prebiotics to promote digestive balance, reduce bloating, and support brain-gut communication. 4. Support the Gut Lining L-glutamine, aloe vera, and collagen can help repair a leaky gut. You can find these in many gut repair powders or take them separately. Explore our detox and cleanse supplements for comprehensive support. 5. Hydrate Intentionally Drink filtered water consistently throughout the day. Add sea salt or electrolytes to help absorption, especially if you’re sweating more than usual. 6. Focus on Anti-Inflammatory Foods Include foods like leafy greens, turmeric, wild salmon, and extra virgin olive oil. These nourish the brain and gut while reducing inflammation. Gut-Healing Foods That Also Fuel Mental Clarity Your food choices play a pivotal role in gut health—and by extension, brain function. Here are some of the best whole foods to incorporate into your daily routine: 1. Fermented Foods Kimchi, sauerkraut, kefir, and unsweetened yogurt are rich in probiotics that help replenish good bacteria in your gut. 2. Prebiotic-Rich Foods Foods like garlic, onions, leeks, asparagus, and green bananas feed the good bacteria and support a thriving microbiome. 3. Omega-3 Rich Foods Wild-caught salmon, sardines, flaxseeds, and chia seeds help reduce inflammation and support the brain-gut connection. 4. Polyphenol-Packed Plants Blueberries, pomegranate, spinach, and dark chocolate (70%+ cacao) provide antioxidants that protect both the brain and gut lining. 5. Bone Broth Loaded with collagen and amino acids like glutamine, bone broth helps seal and heal the gut lining. 6. Clean Proteins Organic pasture-raised poultry, wild-caught fish, and grass-fed beef provide essential nutrients for cellular repair and neurotransmitter production. These foods are a foundational part of the preventative and holistic approach I recommend—and they nourish more than just your body. They create the internal environment needed for peace, energy, and mental clarity. What Scripture Reminds Us About the Body Scripture reminds us that our bodies are a gift from God, and we are called to steward them well: “Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God?” — 1 Corinthians 6:19 Caring for your body—including your gut—isn’t just about physical health. It’s about clarity, energy, and the ability to serve others and fulfill your purpose with excellence. Sometimes the greatest clarity doesn’t come from another coffee or pushing through fatigue. It comes from healing the internal systems God designed to work together in harmony. 🛒 Ready to Support Your Gut?

Dr. Colbert’s Healthy Gut Zone System

AHA Publisher — Wed, 17 Nov 2021 08:00:35 +0000

Dr. Don Colbert – Did you know there’s one system in your body that’s responsible for the health of all other systems? Sure, if your nervous system or cardiovascular system fails, the whole body fails. However, there’s one system that functions to maintain the health of all other crucial organs. This one system is the digestive system. Your digestive health is paramount to your entire body’s health, and specifically your brain’s health. Unfortunately, it’s estimated that 60-70 million Americans suffer from chronic digestive issues each year (1). Some are severe. Some are more minor. All impede everyday life to some extent and affect every other system in the body. It’s for this reason that Dr. Colbert has created an amazing system to help you care for your digestive health: Dr. Colbert’s Healthy Gut Zone System. This complete kit includes the best probiotics available, a two-fiber supplement powder for complete digestive health, and Dr. Colbert’s Gut Zone book. With the Healthy Gut Zone System, you’ll learn how digestive health affects your entire body and what you can do to keep yours in top-notch shape! Digestive Health, Brain Health and Beyond Amazingly, your digestive health has direct implications for your brain health. In fact, it’s now known that: Gut inflammation promotes brain inflammation and declining function An unhealthy digestive tract promotes illness in other parts of the body Healing your gut can reduce brain fog, increase alertness, support youthful memory, and energize the body and brain Immune function is dependent on a healthy digestive tract Healthy digestion is first responsible for nourishing your body, from your hair to your toes. What’s more, there is an incredible gut-brain connection that impacts your brain health directly. In fact, your digestive tract is home to 75% of your immune system. The health of your brain depends on strong immunity and a healthy gut-brain connection! Are you convinced? Ready to take care of your digestive health above all else? Here are 5 steps you can take today to optimize digestive health and therefore, whole-body health with Dr. Colbert’s Healthy Gut Zone System. 5 Steps to Optimal Health 1. Take Care of the Good Bacteria Forty trillion. This is the number of bacteria in your body. Most are in your intestines. And, most are there to help you. It’s time to start helping them. How? It’s simple, really. The first thing to do is to replenish and fortify your healthy bacteria with probiotic supplements and foods. Within Dr. Colbert’s Healthy Gut Zone System, you’ll receive Dr. Colbert’s Beyond Biotics Ultra Blend. Beyond Biotics is a probiotic supplement that contains live, viable probiotic bacteria in pill form. It is specifically beneficial to modern-day humans since we have many food-supply, environmental, and chemical compounds that harm our digestive tracts and bacteria. Both anecdotal reports and studies show that probiotics help acute digestion symptoms. They can also produce beneficial effects on the bacteria in the gut (2). What’s more, they can affect other health issues within the body as they improve digestion comfort, nutrient absorption and microbiota (3, 4, 5). In addition, Dr. Colbert’s Gut Zone Book emphasizes healthy foods you can consume to fortify your digestive tract’s healthy bacteria. These include Divine Health® Fermented Greens Supremefoods, plain yogurt, kimchi, sauerkraut, kefir, kombucha, tempeh, and more. Don’t leave your healthy bacteria to fend for themselves. Fortify them with probiotics each day. 2. Fortify Your Digestive Tract with Fiber Next, you can fortify your digestive tract with fiber. Dr. Colbert’s Keto Zone® Fiber Zone is included in the Healthy Gut Zone System. Dr. Colbert’s Keto Zone® Fiber Zone is a delicious fiber powder specially formulated using 2 of the most powerful, important fibers available. First, it contains psyllium husk. Psyllium husk is made of both soluble (70%) and insoluble fibers (30%). This means twice the benefits. It acts as a prebiotic, feeding and fortifying healthy gut bacteria. Its insoluble fiber passes through the digestive tract, providing bulk and softness to stools. This encourages digestive health, reduced inflammation, and a healthy gut-brain connection (6). Next, Fiber Zone contains inulin. Inulin is a prebiotic fiber. Like psyllium, it feeds the healthy bacteria and cells in our digestive tracts, making them stronger and healthier (7). Together, these fibers work to reduce hunger cravings, support healthy digestion, encourage optimal weight, support bone health and optimize the gut-brain connection (8). In addition, following Dr. Colbert’s Gut Zone Book, eat healthy high fiber and prebiotic foods. These include berries, artichokes, asparagus, broccoli, greens, onions, garlic, leaks, cacao, flaxseeds, hemp heart seeds, nuts, and more. 3. Nourish With Collagen Collagen is another great food for your digestive health! In fact, collagen supports healthy digestion, joint health, vibrant skin, healthy weight, and more! In particular, those who suffer from leaky gut syndrome can find relief by adding collagen to their diets. With this digestive issue, toxins, allergens and large particles are able to pass from your gut into your bloodstreams, causing negative reactions. Collagen can help fortify connective tissue in the protective lining of the digestive tract. It heals it and helps it seal out the offending particles. Further, it supports better digestive health in those who suffer from inflammatory digestive issues, acid reflux, and more (9). Keto Zone® Collagen Powder is a great source of collagen. It is enzymatically hydrolyzed, or predigested, for effortless digestion and full absorption into the body. It is derived from chicken and marine peptides, and contains Types I, II, and III collagen. This combination of collagen supports the formation of elastin in the body, which is critical in fighting against wrinkles and sagging skin. 4. Avoid Harmful Substances Did you know some substances you consume actually harm digestive health? Some foods, drinks, and environmental contaminants harm or destroy digestive cells, healthy bacteria, and more. These include: Sugar: Sugar can harm the digestive tract in a few ways. First, it promotes the growth of harmful Candida albicans which can lead to leaky gut and other digestive issues (10). Next, high-sugar diets increase gut permeability, degrades healthy gut barriers, increases spleen weight, and increases inflammatory immune response in animal studies (11). Man-Made Artificial Sweeteners: Chemical artificial sweeteners have been widely used in “diet foods.” Unfortunately, they can have negative effects on gut bacteria. Animal and human studies have shown that aspartame, saccharin, sucralose, and other artificial sweeteners can impair gut bacteria (12) allowing other microbes to take over (13). If you use sugar substitutes, make sure they are natural ones like sugar alcohols: xylitol is safe and does not seem to affect gut bacteria (13). Antibiotics: In recent years, there has been a push to drastically reduce the use of antibiotics in humans and animals. Most doctors have been urged to only prescribe antibiotics only when necessary, and with much less frequency than in previous decades. The overuse of antibiotics has been shown to 1) hurt the gut by wiping out healthy bacteria, and 2) lead to antibiotic-resistant bacteria. In fact, the World Health Organization is also working to reduce the antibiotics that humans consume. It is recommending that routine antibiotic use in animals is stopped and reserved only when the animal is sick (14). Alcohol: Unfortunately, alcohol, especially in large quantities, can negatively affect the bacteria colonies in the gut. In fact, many people who abuse alcohol have impaired nutrient absorption, poor digestion, and discomfort. When used in moderation, bacteria colonies can remain healthy. But, overuse of alcohol can destroy them (15). Nicotine: Nicotine is harmful to digestive health. It has been associated with excess reflux, peptic ulcers, and a decrease in colon strength. What’s more, smokers experience higher Helicobacter pylori infections (16). While you use the tools in Dr. Colbert’s Healthy Gut Zone System, you will learn to also avoid these compounds that harm your digestive system. 5. Be Active, Hydrate, and Reduce Stress Your lifestyle choices make a difference in the health of your digestive system. First, exercise can improve digestion. Movement and gravity helps food naturally move through your intestines. On the other hand, a sedentary lifestyle actually harms the digestive system. When we sit all day, our digestive tract is kinked. This makes natural, healthy digestion more difficult. Make sure to get up frequently and include physical activity each day to support healthy digestion. Next, healthy digestion depends on the presence of fluids. Water helps break down food, lubricates the digestive tract, reduces constipation, and keeps your cells healthy. Make sure to drink water throughout each day. Lastly, chronic stress can have a negative effect on digestion. In fact, chronic stress can decrease the blood flow to the intestines, slow nutrient absorption, and even change how the bacteria in your gut function. One way to reduce stress? In addition to daily de-stress strategies, make sure you stay hydrated! Dehydration is linked to elevated cortisol levels. Bottom Line You can improve your digestive health, support your entire body, and improve brain function, alertness and health starting today!
