What to eat to restore the gut?

Gut health plays a central role in overall wellness, from aiding digestion and nutrient absorption to influencing immune function, mood, and energy. This blog post explores exactly what to eat to restore the gut, covering expert insights into the role of the gut microbiome, how gut microbiome testing can personalize your diet, and which foods support digestive recovery. Whether you're struggling with persistent bloating, low energy, or chronic digestive discomfort, understanding the connection between food and your microbiome can help restore gut balance and improve overall health. You’ll find actionable tips, food lists, meal ideas, and strategies for rebuilding a healthy, diverse gut ecosystem.

Introduction

Our understanding of health has undergone a paradigm shift in recent years, with the gut microbiome emerging as a central player in almost every major physiological system. Gut health isn’t just about avoiding digestive discomfort—it’s tied to your immune resilience, energy levels, emotional balance, and long-term disease risk. With trillions of microorganisms living in our digestive tract, many of which play important roles in regulating inflammation, producing vital nutrients, and protecting the gut lining, maintaining a healthy gut is foundational to vibrant health.

Modern lifestyle factors—such as poor diet, chronic stress, inadequate sleep, overuse of antibiotics and medications—can damage the microbiome and trigger dysbiosis (an imbalance in gut flora). This imbalance can manifest in many ways: bloating, fatigue, autoimmune flare-ups, frequent illness, skin irritations, and even anxiety or depression. By focusing on diet and nutritional interventions, much of the damage can be reversed.

Thanks to innovations in science, we no longer need to guess what’s going on inside our gut. With tools like gut microbiome testing, it’s possible to identify specific imbalances—such as an overgrowth of harmful bacteria or deficiencies in beneficial strains—and tailor your nutrition strategy accordingly. Understanding your unique microbial make-up gives you the power to make informed, personalized choices that can restore your gut’s health naturally and effectively.

Understanding the Gut Microbiome and Its Impact on Your Health

The gut microbiome is the collective community of trillions of bacteria, viruses, fungi, and other microorganisms dwelling in the gastrointestinal tract. Most reside in the large intestine (colon) and work in symbiosis with our bodies, aiding functions we are not capable of performing on our own—such as fermenting indigestible fibers, synthesizing vitamins, and maintaining the integrity of the intestinal barrier.

A balanced gut microbiome is a sign of inner harmony. Each species performs essential tasks that impact everything from digestion to immune readiness to brain chemistry. A diverse microbiome (meaning it houses a wide variety of microbial species) is generally associated with better overall health outcomes. Diversity ensures resilience: the more “voices” in your microbial ecosystem, the more adaptable and resistant it is to outside stressors.

When this system becomes imbalanced due to dietary deficiencies, antibiotic usage, or lifestyle stressors, harmful bacteria can gain the upper hand. This dysbiosis leads to inflammation, impaired digestion of food, weakened immune responses, and even increased permeability of the gut lining—what is commonly referred to as “leaky gut.”

Microbiome testing kits now allow scientists and health enthusiasts alike to categorize and quantify the species present in your gut. These tests can detect overgrowth of detrimental strains like Clostridium difficile or pathogenic E. coli and assess for shortages in beneficial ones such as Lactobacillus or Bifidobacterium. Importantly, such insights can suggest precise foods, probiotics, or lifestyle practices to re-establish microbial equilibrium.

Gut Health: Why It Matters and How Testing Helps

Research increasingly shows that gut health has far-reaching impacts across multiple body systems. More than 70% of your immune system lies in your gut, where bacteria help regulate immune responses and ward off pathogens. Disruptions can lead to increased infection risk, autoimmune diseases, and food sensitivities.

The gut-brain axis—an information superhighway connecting your central nervous system and intestines—facilitates bidirectional communication through neurotransmitters, hormones, and even bacterial metabolites. This is why gut imbalances are strongly linked with mental health conditions such as anxiety, depression, and even neurodegenerative diseases.

Digestive symptoms are just the tip of the iceberg. Common signs of gut imbalance include:

• Persistent gas or bloating
• Constipation or diarrhea
• Brain fog and poor concentration
• Unexplained fatigue
• Autoimmune flares (e.g., psoriasis, rheumatoid arthritis)
• Frequent illness or infections
• Skin issues like eczema or acne

This is where microbiome testing shines. With an in-depth report from options like the InnerBuddies gut microbiome test, you gain insight into the species present in your bowel and their relative abundance. Based on this profile, it’s possible to tailor an eating strategy that supports beneficial strains, suppresses harmful ones, promotes mucosal healing, and restores gut integrity from the inside out.

Digestive Wellness: Foundations for Restoring Your Gut

Gut restoration isn’t solely about what you eat—it’s about how your body digests and assimilates those nutrients. Digestion starts in the brain, and stress notoriously inhibits proper digestive function by activating the sympathetic nervous system. That’s why mindful eating, stress management, hydration, and sleep quality all form a foundational layer of gut recovery.

Start by slowing down at meals. Chew thoroughly and focus on your food, engaging all your senses. This allows your body to prepare digestive enzymes and gastric acids essential for nutrient breakdown. Eating in a parasympathetic (relaxed) state maximizes absorption and minimizes bloating or discomfort.

Hydration supports mucosal barrier function and helps lubricate the digestive tract. Sip water throughout the day, but minimize intake during meals to avoid diluting enzymatic activity. Sleep is another pillar. During deep rest, tissue repair and parasympathetic processes help balance the microbiome and modulate inflammation.

Stress, whether emotional or physical, is a major disruptor of gut function. Cortisol, the primary stress hormone, can impair the diversity and composition of friendly bacteria. Incorporate stress-reducing activities like meditation, nature walks, journaling, or gentle yoga to help your gut repair itself naturally.

Gut Recovery Foods: Nourishing Your Microbiome with the Right Nutrients

Food is the single most powerful tool for rebuilding a healthy gut. Just as ultra-processed, high-sugar foods can promote dysbiosis, nutrient-dense, fiber-rich foods support the growth of good bacteria and aid intestinal repair.

Key gut-healing foods include:

• Fiber-rich vegetables: Asparagus, leeks, onions, and artichokes contain inulin, a prebiotic that feeds friendly microbes.
• Fruits: Bananas, berries, and apples (with skin) are loaded with pectin and polyphenols that nourish beneficial bacteria.
• Fermented foods: Yogurt, sauerkraut, kimchi, miso, and kefir contain live cultures that reintroduce good bacteria to the gut.
• Bone broth: Rich in collagen, gelatin, glutamine, and glycine, bone broth can soothe and restore the gut lining.
• Omega-3-rich fats: Fatty fish, flaxseeds, and walnuts reduce inflammation and promote mucosal recovery.

Foods to avoid when restoring the gut:

• Refined sugars and simple carbs
• Ultra-processed meals and snacks
• Artificial sweeteners (e.g., aspartame, sucralose)
• Excess alcohol and coffee
• Gluten and dairy (for sensitive individuals)

Here’s a simple sample gut-healing meal plan:

• Breakfast: Greek yogurt with chia seeds, berries, and a drizzle of raw honey
• Snack: A piece of fruit with walnuts
• Lunch: Quinoa bowl with roasted sweet potatoes, kale, avocado, and fermented sauerkraut
• Snack: Celery sticks with almond butter
• Dinner: Baked salmon with steamed broccoli and bone broth–cooked rice

Probiotics for Gut: Enhancing Microbial Diversity Through Supplementation

Probiotics are live microorganisms that, when consumed in adequate amounts, confer health benefits—especially in rebalancing the gut microbiome after damage. Supplemental probiotics and probiotic-rich foods can reintroduce missing strains and help crowd out pathogenic microbes.

The right probiotic strain depends on your microbiome profile. Some strains target specific issues: Lactobacillus rhamnosus may reduce bloating, while Bifidobacterium longum has been shown to help with constipation and mental wellbeing. That's why we advocate for microbiome testing first—it helps guide personalized probiotic selection tailored to your needs.

Incorporate probiotic-rich foods into your daily meals:

• Kefir or drinkable yogurt (high in Lactobacillus and yeasts)
• Raw sauerkraut (ensure it’s refrigerated for live cultures)
• Kombucha (a fermented tea with probiotics and beneficial acids)
• Tempeh and miso (fermented soy products)

If choosing a supplement, look for high-CFU counts (20-50 billion per day), a variety of strains, and products stored properly for shelf-life stability. Take your supplement consistently for at least four weeks, ideally after a meal (usually breakfast or dinner).

Intestinal Healing Diet: Specific Nutritional Strategies for Repair

Restoring the gut sometimes requires more advanced nutritional strategies, particularly for people with chronic conditions, food sensitivities, or inflammatory gut disorders. Protocols like the Low FODMAP diet and the Specific Carbohydrate Diet (SCD) work to minimize fermentable sugars or complex carbohydrates that feed harmful bacteria in sensitive individuals.

These diets eliminate certain high-reactivity foods for a period before reintroducing them one at a time. This helps identify triggers that may be causing ongoing bloating, inflammation, or pain. Elimination diets should not be long-term unless guided by a health practitioner, as they may limit dietary diversity.

Additional nutrients for intestinal repair include:

• L-Glutamine: An amino acid that fuels intestinal cells and supports tight junction integrity
• Collagen peptides: Help regenerate gut tissue and reduce permeability
• Omega-3s (EPA/DHA): Metabolically calm inflammation throughout the gut wall
• Zinc and magnesium: Support enzymatic repair and immune modulation

Follow these principles when implementing a healing diet:

• Keep a symptom journal to track responses to meals
• Cook at home using whole ingredients—minimize dining out
• Start small: eliminate top culprits (gluten, dairy, sugar) and build from there
• Consider working with a health coach, nutritionist, or using precision testing tools to guide the process

Nourishing Gut Bacteria: Building a Resilient Microbiome

Once gut balance is restored, the next goal is maintenance and microbial resilience. Long-term gut health isn’t achieved through short-term plans—it's built with consistent daily habits.

Focus on microbial “feeding” with whole foods and fiber. Polyphenols (in berries, green tea, olive oil), resistant starches (in cooked/cooled potatoes, legumes), and cruciferous vegetables (like broccoli and cabbage) help diverse microbes flourish. Avoid overly restrictive diets that limit fermentable fibers essential to beneficial strains.

Exercise, moderate and consistent, has been shown to support microbial diversity and enhance SCFA (short-chain fatty acid) production. Spend time in nature, play with pets, limit antibiotic use, and cook with diverse fruits, herbs, and vegetables to keep new microbial “messages” coming in.

Finally, avoid returning to gut-damaging foods. Occasional indulgences are fine, but the cornerstone of recovery is consistency. If symptoms recur, reevaluate your diet or consider another round of microbiome testing to spot emerging imbalances before they create major health problems.
