Leaky gut syndrome is a condition that’s thought to affect millions of people, many of whom don’t even know it. The good news is following a leaky gut diet can help overcome this condition.

From the sound of it, you might think leaky gut syndrome only impacts digestive health, but in reality it can lead to many other health conditions. For example, according to recent research, the cause of your food allergies, fatigue, joint pain, thyroid disease and autoimmune conditions may be a leaky gut.

What is the fastest way to treat leaky gut? Following a healing leaky gut syndrome diet is one of the best strategies for getting your body back on track.

In this article, I outline specifically how a leaky gut diet works so you can break through some of the stubborn health problems you’ve been struggling with.

What Is Leaky Gut?

Leaky gut syndrome is a condition that affects the integrity of the gut lining, which normally serves as the barrier of the intestines. Also called “intestinal permeability,” it occurs when the gut wall becomes damaged, allowing compounds to enter and become absorbed into the bloodstream that normally shouldn’t.

For example, partially digested proteins and fats may seep through the intestinal lining, making their way into the bloodstream, which causes an allergic response.

Causes/Symptoms

How do you know that you may benefit from a leaky gut treatment plan? One of the biggest warning signs that you may have leaky gut is that you’re experiencing multiple food sensitivities.

Allergic responses caused by a leaky gut don’t necessarily mean you’ll break out in a rash all over your body, but leaky gut can lead to various other symptoms. Some potential symptoms linked to leaky gut can include:

If not repaired, intestinal permeability can potentially lead to more severe health issues, such as:

According to research published in the Journal of Diabetes, there is a strong body of evidence suggesting that leaky gut syndrome is related to certain autoimmune diseases, such as type 1 diabetes.

Additionally, another problem with leaky gut is that it can cause malabsorption of vital minerals and nutrients, including zinc, iron and vitamin B12.

Experts recommend that you take a leaky gut test to better identify if this may be a root cause of your symptoms and help pinpoint potential contributing factors.

What causes leaky gut?

Leaky gut can be caused by a number of factors, including:

• a poor diet (low in fiber and high in sugar)


• smoking


• alcohol use


• frequent use of some medications


• genetic predisposition

Some potential dietary causes include:

• Lectins — These are found in many foods, not just grains, and when consumed in smaller amounts, your body normally does just fine with them. But foods that have large amounts of lectins are more problematic. Some of the lectins and foods that cause leaky gut include wheat, rice, spelt and soy.


• Conventional cow’s milk — This is another food that can cause leaky gut. The component of dairy that harms your gut is the protein A1 casein. Also, the pasteurization process destroys vital enzymes, making sugars like lactose very difficult to digest.


• Gluten-containing grains — These may damage your intestinal lining depending on how well you tolerate them. Once your gut is healthy, you can likely add back in grains that have been fermented and sprouted to eat occasionally.


• Sugar — Added sugar is another substance that can wreak havoc on your digestive system when eaten in large amounts. Sugar can feed the growth of yeast, candida and bad bacteria, which further damages your gut. Bad bacteria actually creates toxins called exotoxins that damage healthy cells and can eat a hole into your intestinal wall.

Leaky Gut Diet Foods to Eat

If you suffer from leaky gut syndrome, you’re overdue to consider adopting a leaky gut diet. Such a diet contains foods that support healing because they are easy to digest and can help repair the lining of the intestines.

Here are the best foods to include in a leaky gut syndrome diet:

• Bone Broth — Bone broth contains collagen and the amino acids proline and glycine that can help heal your damaged cell walls. I’ve had many of my patients do a bone broth fast for three days to help treat leaky gut and autoimmune disease.


• Raw Cultured Dairy — Raw dairy contains beneficial bacteria when fermented and short-chain fatty acids that can help heal the gut. Pastured kefir, yogurt, amasai, butter and raw cheese are some of the best options.


• Fermented Foods — In addition to fermented dairy products, fermented vegetables are some of the healthiest probiotic foods. They contain organic acids that balance intestinal pH and probiotics to support the gut. Sauerkraut, kimchi and kvass are excellent sources.


• Coconut Products — All coconut products are especially good for your gut. The medium-chain fatty acids in coconut are thought to be easier to digest than other fats so they work well for maintaining digestive health. Also, coconut kefir contains healthy microbes that support your digestive system.


• Sprouted Seeds — Chia seeds, flaxseeds and hemp seeds that have been sprouted are great sources of fiber that can help support the growth of beneficial bacteria. If you have severe leaky gut, you may need to start out getting your fiber from steamed vegetables and fruit.


• Healthy Fats — Consuming healthy fats in moderation, like egg yolks, avocados, ghee and coconut oil, is easy on the gut and promotes nutrient absorption.


• Omega-3 Fats — Certain protein foods also contain healthy omega-3 fats, such as grass-fed beef, lamb and wild-caught fish like salmon. These fats benefit the gut microbiome.


• Fruit – Consuming one to two servings of fruit daily is a good way to obtain vitamins and minerals. You can steam apples and pears to make homemade apple sauce or fruit sauce. Fruit is best consumed in the morning and not later on in the day, and remember to keep fruit intake in moderation.

In addition to eating a leaky gut diet, you can help repair your gut with certain supplements.

In a leaky gut treatment plan, there are many supplements that support digestive health as well as protect the gut lining from further damage. I believe the six most beneficial leaky gut supplements are:

• Probiotics (50–100 billion units daily) — This is the most important supplement to take because it helps replenish good bacteria and crowds out bad bacteria. I recommend getting probiotics in both food and supplement form. By only following part of the protocol in treating leaky gut syndrome by removing the damaging irritants, you may fail to re-inoculate the gut with beneficial bacteria that will keep bad bacteria at bay. Based on available research, look for strains like Bacillus clausii, Bacillus subtilis, Saccharomyces boulardii and Bacillus coagulans.


• Digestive enzymes (one to two capsules at the beginning of each meal) — These ensure that foods are fully digested, decreasing the chance that partially digested food particles and proteins are damaging your gut wall.


• L-Glutamine — Critical for any program designed to heal leaky gut, glutamine powder is an essential amino acid supplement that has anti-inflammatory properties and is necessary for the growth and repair of your intestinal lining. L-glutamine benefits include acting as a protector, coating your cell walls and acting as a repellent to irritants.


• Licorice Root — An adaptogenic herb that helps balance cortisol levels and improves acid production in the stomach, licorice root supports the body’s natural processes for maintaining the mucosal lining of the stomach and duodenum. This herb is especially beneficial if someone’s leaky gut is caused by emotional stress due to how it can help improve the way you produce and metabolize cortisol.


• Shilajit — A tar-like medicinal herb used frequently in Ayurvedic medicine, shilajit can protect from stomach ulcers as well as reduce inflammation triggered or exacerbated by leaky gut.


• Marshmallow Root — Because it has antioxidant and antihistamine properties, marshmallow root makes a great addition to any natural medicine cabinet, particularly for those struggling with gut-related issues.

Leaky Gut Diet Foods to Avoid

What foods should you avoid if you have leaky gut syndrome? It’s essential to avoid or greatly limit allergens and inflammatory foods when following a leaky gut diet.

Foods/ingredients to avoid include:

Ad

• Unsprouted grains, especially those containing gluten (wheat, rye and barley) — note that sprouting and fermenting grains reduces phytates and lectins, making these foods easier to digest


• Processed foods made with added sugar


• GMOs foods (GMO and hybridized foods tend to be the highest in lectins since they have been modified to fight off bugs)


• Refined oils


• Processed foods made with synthetic food additives


• Conventional dairy products


• Heavy alcohol use
