Your food choices are the most powerful medicine for repairing your gut. With the right nutrition, your body can rebuild the gut lining, rebalance your microbiome, and restore immune health.

What Is Leaky Gut?

“Leaky gut,” or increased intestinal permeability, occurs when the tight junctions in your intestinal wall become damaged—allowing toxins, food particles, and pathogens to leak into the bloodstream. This triggers inflammation and contributes to a wide range of symptoms, including:

• Bloating and irregular digestion

• Brain fog and fatigue

• Anxiety and mood swings

• Food sensitivities

• Skin conditions like eczema or acne

• כאב מפרקים

• Autoimmune disorders

Signs Your Gut Needs Healing

• Daily gas, bloating, or constipation

• Cravings for sugar or carbs

• Reactions to gluten, dairy, or other foods

• Poor immune function or frequent infections

• Inflammation that won’t go away

• Hormonal imbalances or irregular cycles

If these sound familiar, it’s time to reset your gut—starting with food.

Best Foods for Natural Gut Healing

1. Cooked Non-Starchy Vegetables
Easier to digest than raw, these veggies provide fiber and antioxidants to feed good bacteria and reduce inflammation. Try zucchini, carrots, spinach, and fennel.

2. Bone Broth
Rich in collagen, glycine, and glutamine—amino acids that support gut lining repair and reduce leaky gut symptoms.

3. Fermented Foods
Unpasteurized sauerkraut, kimchi, coconut yogurt, and kefir naturally repopulate your microbiome and restore digestive balance.

4. Ground Flax and Chia Seeds
These create a soothing gel that helps eliminate toxins, support bowel regularity, and feed healthy gut flora.

5. Wild-Caught Fish and Healthy Fats
Omega-3 fatty acids from salmon, sardines, avocado, and olive oil reduce gut inflammation and help modulate immune function.

6. Garlic, Ginger, and Turmeric
Natural antimicrobials that help balance bad bacteria while calming inflammation and supporting motility.

7. Berries and Polyphenol-Rich Foods
Blueberries, green tea, pomegranate, and herbs like rosemary feed good bacteria and improve barrier integrity.

Foods That Damage Gut Health

To allow your gut to repair, eliminate or significantly reduce the following:

• Gluten and conventional grains

• Dairy products (especially conventional or pasteurized)

• Refined sugars and artificial sweeteners

• Industrial seed oils (canola, soybean, corn oil)

• Processed and packaged foods

• Alcohol and excessive caffeine

These foods increase gut permeability, feed harmful bacteria, and disrupt immune function.

You Don’t Need Supplements to Heal

Most gut-healing supplements on the market are expensive, unregulated, and often unnecessary. Unless prescribed by a licensed clinical nutritionist, supplements can backfire—especially for sensitive individuals.

If you’re considering supplements, we recommend working with a certified nutritionist.
