The key to a healthy, resilient gut lies in something known as microbial diversity. Improving your gut microbiome diversity could be one of the most important things you do to improve your health. If you have never heard of gut microbial diversity, what this means is that you have a high number of different bacterial species that are spread out across your gut microbiome. These various species of gut bacteria serve several important functions such as aiding in digestion and synthesizing vitamins, aiding with absorption, maintaining oral tolerance (preventing allergies and sensitivities), maintaining the integrity of the gut mucosal barrier, production of short-chain fatty acids and so much more (*),(*),(*)

Gut diversity has become an important biomarker for gut health because numerous studies, have shown that when you have lower microbial diversity, you will suffer from various diseases such as inflammatory bowel disease, type 1 diabetes, obesity autoimmune disease, Skin disorders, cardiovascular disease, and thyroid problems. (*),(*),(*)

When Hippocrates said “All Disease Begins In The Gut” I’m not sure if he realized just how powerful that statement was and is today. Almost every chronic health problem is influenced by some aspect of gut health. Well if you are someone who doesn’t have the greatest of gut health, stay tuned because I have some good news for you, there are several simple ways to enhance gut microbial diversity and improve your gut health! And that’s the topic of today’s video.

Well Hey there!!! I’m Dr Hagmeyer and In today’s video, I want to give you several dietary tips and strategies to help improve your gut microbiome diversity.  I’ve got 9 Gut health tips that will have a dramtic improvement on your gut health and I promise you that one of them is going to be a gut microibome game-changer for you.

Tip # 1. Eat More Fermented and Probiotic-Rich foods

Fermented foods undergo a process where natural bacteria feed on the sugar and starch in the food, creating lactic acid. This process not only preserves the food but also cultivates beneficial bacteria, commonly known as probiotics.

Foods like yogurt, kefir, sauerkraut, kimchi, and miso contain live beneficial bacteria known as probiotics. Consuming these fermented foods can introduce new bacterial strains into the gut and support microbial diversity.

The beneficial bacteria from fermented foods can outcompete pathogenic bacteria for resources and space, supporting a healthier microbial balance. These bacteria found in fermented foods can also produce short-chain fatty acids and other beneficial compounds that nourish other gut bacteria, fostering a diverse microbial environment. Some studies suggest that probiotics from fermented foods can help improve gut barrier integrity, potentially reducing “leaky gut” symptoms, which can negatively affect microbiome balance and diversity.

Opt for unpasteurized and naturally fermented products for maximum probiotic content.

While fermented foods have many potential benefits for gut health and diversity, their effects can vary from person to person based on individual microbiome composition, genetic factors, and dietary habits.

Introducing a variety of fermented foods can be a beneficial component of a diet aimed at enhancing gut health, but If you’re new to fermented foods, start slow to allow your gut to adjust to the influx of new bacteria but after a while a daily intake of fermented foods—can provide a wide variety of probiotic strains that improve your gut microbial diversity.

Tip # 2. Polyphenols

While probiotics and fermented foods often steal the limelight, polyphenols are another crucial component for enhancing gut health by increasing bacterial biodiversity. Eating colorful fruits and veggies that contain polyphenols—like flavonoids and carotenoids—can feed healthy gut bacteria, especially Bifidobacterium and Akkermansia muciniphila and increase your gut gut microbial diversity.

Polyphenols act as food for beneficial gut bacteria, particularly for strains like Bifidobacteria and Lactobacilli. As these bacteria break down polyphenols, they proliferate, contributing to a richer microbial diversity.

When polyphenols are metabolized by gut bacteria, they produce bioactive compounds that further promote healthy gut flora. Short-chain fatty acids (SCFAs) like butyrate, propionate, and acetate, which are beneficial for gut lining health and inflammation reduction, are among these metabolites

If you have low levels of either of these bacteria you are more likely to develop metabolic disorders, intestinal inflammation, Yeast infections, and a Leaky gut.  If you didn’t watch my video on Akkermansia, be sure to check out the description box where I will leave a link for that video.

Tip # 3. Increase Your Fiber

Increasing the amount of fiber, we eat is one of the best ways to improve gut bacterial diversity. A diverse gut microbiome is resilient, adaptive, and better able to respond to various challenges, including dietary changes and infections.

There are two main types of fiber: soluble and insoluble. Both types play pivotal roles in gut health, but they do so in slightly different ways.

1. Soluble Fiber: This type dissolves in water and forms a gel-like substance. It can be fermented by bacteria in the large intestine, producing beneficial short-chain fatty acids (SCFAs) like butyrate, propionate, and acetate.
2. Insoluble Fiber: This type doesn’t dissolve in water. It adds bulk to the stool and helps speed up the passage of food through the gut.

You see when we consume fiber and starches from fruits, vegetables, nuts, and seeds, the bacteria in our gut begin to ferment them and, in the process, produce short-chain fatty acids (SCFA). Short-chain fatty acids in turn are anti-inflammatory, immunoregulatory, anti-obesity, anti-diabetes, anticancer, cardiovascular protective, liver protective, and finally neuroprotective activities. (*)

When you eat more fiber, especially different types, you will start to nourish and support different types of microbes, leading to a more diverse microbial community(*).

Different bacteria prefer different types of fiber so a diet high in varied fibers can feed a broader range of bacterial species, contributing to greater microbial diversity and conssequently and improvement in gut health. If you have SIBO read this article on the best types of fiber to eat. 

Tip # 4. Avoid Antibiotics At Every Chance

If there is one thing you should remember when it comes to bacteria, You should remember that Antibiotics severely reduce microbial diversity in our bodies.

Antibiotics work by killing bacteria, both harmful and beneficial, to eradicate infections. This broad-spectrum approach disrupts the delicate balance of our gut microbiota, often leading to a major decrease in microbial gut diversity.

When beneficial bacteria are eliminated, and we have reduced bacterial diversity, opportunistic disease-causing bacteria and yeast can flourish, putting us at risk for disease.

To minimize these effects, using antibiotics judiciously and considering post-antibiotic probiotic supplementation can help minimize the damaging effects caused by antibiotics. But I want to be clear, taking probiotics does not necessarily mean it’s your get-out-of-jail free card. In some cases, the changes in the microbiome caused by antibiotic use, sometimes can’t be reversed.

Tip # 5 Probiotics 

Incorporating high-quality probiotic supplements into your daily regimen can be a game-changer for your gut health

Probiotic supplements introduce beneficial bacteria directly to the gut, helping to colonize the intestinal lining and outcompete harmful pathogens.

When it comes to selecting probiotics to increase gut microbial diversity, it’s important to note that individual responses to probiotics can vary. However, several strains have been studied extensively and shown promising results in promoting a diverse and healthy gut microbiota. 

Some of the best probiotic strains known for their ability to increase gut microbial diversity include lactobacillus acidophilus, Bifidobacterium bifidum, Lactobacillus plantarum, Lactobacillus rhamnosus.

It’s important to choose probiotic supplements that contain multiple strains, as different strains can have different effects on the gut microbiome. Look for products that mention the specific strains they contain and have been tested for their efficacy and stability. 

 Probiotic Supplements To Help Improve Gut Microbiome

1. Lactobacillus acidophilus: This strain is commonly found in the human gut and is known for its ability to promote a balanced gut microbiota. It has been shown to improve gut health and support a diverse microbial community.
2. Bifidobacterium bifidum: This strain is known for its ability to create an environment in the gut that is favorable for the growth of beneficial bacteria. It helps maintain a healthy microbial balance and supports optimal gut function
3. Lactobacillus plantarum: This strain is known for its antimicrobial properties, which can help control the growth of harmful bacteria. It has been shown to support gut health and promote microbial diversity.
4. Bifidobacterium longum: This strain is commonly found in the human gut and is known for its ability to support diverse gut microbiota. It helps maintain gut barrier integrity and supports overall gut health.
5. Lactobacillus rhamnosus: This strain has been extensively studied for its beneficial effects on gut health. It can help promote a balanced gut microbiota and support overall digestive health.

It’s important to choose probiotic supplements that contain multiple strains, as different strains have different effects on the gut microbiota. Look for products that mention the specific strains they contain and have been tested for their efficacy and stability. Here are a few I Recommend.

• Maintenance- Ortho biotic  
• Probiotics for SIBO-Ortho Spore IG
• Probiotics For Diarrhea- Saccharomyces boulardii
• Probiotics For Children- Flora bites (chewable)
• Probiotics Post Antibiotics- Orthobiotic 100

Tip # 6. Avoid Processed Foods At All Costs

If you are serious about improving gut diversity, In addition, to minimizing the use of antibiotics and consuming fermented foods, eating more fiber, and increasing foods rich in Polyphenols, it’s also important to eliminate processed foods.

The Standard American Diet is one of the most damaging things to our gut diversity. This diet is high in refined sugar, high in the wrong kinds of fats, low in Fiber, Low in Polyphenols, low in (SCFA) Short Chain Fatty Acids (*)

High sugar consumption can lead to hyperglycemia and the high fat consumption can cause the level of toxic bile acids to rise. A diet that is low in fiber, low in polyphenols, high in protein, and high in fat contributes to the production of toxic metabolites in the body.

Taken together, each of these begins to break down our gut barrier, As the mucus layer becomes thinner and thinner, we now are at an increased risk for Leaky Gut Syndrome.

A leaky gut is associated with many different inflammatory and metabolic disorders such as Chronic Diarrhea, Constipation, bloating, Nutritional deficiencies, Fatigue, Headache, Confusion, Difficulty concentrating, Skin problems, such as acne, rashes, or eczema, joint pain, widespread inflammation.

By avoiding processed foods, and following an anti-inflammatory diet Rich in polyphenols, rich in fiber, you will be nourishing your gut bacteria and this in turn will encourage their growth and improve your gut microbiome.

Tip # 7. Alcohol, Smoking, Sugar

While on the topic of food and lifestyle habits, I take a bit of a stronger stance on Alcohol, smoking, and sugar. If you are serious about your gut health, you NEED to Stop drinking alcohol, stop smoking, and stop using sugar.

These three things provide ZERO benefit when it comes to the health of your gut and so why some doctors tiptoe and use words like reduce is absurd. I’m not going to sugarcoat this for you.

Alcohol alters the composition of gut bacteria by promoting the growth of harmful species while reducing beneficial ones. This shift in microbial balance has been linked to various gastrointestinal issues and immune system dysregulation, alcohol has been shown to shift microbial populations that promote the development of SIBO and SIFO (*),(*) and it has also been shown to thin out the mucous layer of the gut leading to an increase in intestinal permeability or Leaky Gut syndrome.

When it comes to smoking, Smoking is known to negatively affect numerous aspects of health, and its impact on gut microbial diversity is again no exception.

Studies have shown that smoking raises the pH of the intestinal environment (it makes it more alkaline)(*), induces chronic low-grade inflammation (*), and promotes oxidative stress and tissue damage due in part to excess free radicals.

All of these things, alter the gut microbial composition, reducing microbial diversity and promoting the growth of harmful disease-causing bacteria.

When it comes to sugar, well….. this one should be common sense consumption of refined sugars and sugary foods can have detrimental effects on gut microbiome diversity for many of the same reasons alcohol and smoking is so damaging to the gut. A diet high in sugar feeds harmful bacteria at the expense of beneficial species.

This imbalance can result in increased intestinal permeability, inflammation, and a higher risk of metabolic disorders.

If you are serious about promoting a diverse and healthy gut microbiome, it is crucial to eliminate refined sugars, alcohol, and smoking.  But again, only do this if you are serious about improving your gut health. Let’s talk about stress for just a moment because in conventional medicine, no one is talking about the impact stress has on various aspects of gut health and this can be a make or break for people with GI problems.

Tip # 8. Manage Stress and Cortisol levels:

The gut and the brain are intricately connected through a two-way communication pathway known as the gut-brain axis. This pathway allows for constant communication between the gut microbiota and your brain. Studies have shown that both acute and chronic stress can alter motility, digestion alter intestinal inflammation as well and the balance and diversity of our gut bacteria.

Gut diversity and the health of the gut microbiome have an inverse relationship. In other words, the less gut diversity you have, the sicker your gut microbiome, and Stress impacts gut health in several ways.

You see during times of stress, Your adrenal glands will produce a hormone called cortisol.  When cortisol levels are elevated, it will suppress your immune system defenses namely something called Secretory IgA.  (*,*)

Secretory IgA is your first line of defense against invaders in the mucosal tissues of your body. When these stress hormones run high and secretory IgA levels run low, you are going to run into issues with the permeability of your gut barrier permeability leading to Leaky Gut Syndrome. (*) and you are going to develop all kinds of bacterial, parasitic, and fungal overgrowth. Siga helps keep this all in check.

Research also shows that these high cortisol levels can directly impact the composition and diversity of gut bacteria, meaning that stress decreases the good beneficial bacteria (*) and increases the pathogenic harmful bacteria.

Studies have also shown that this shift and change in microbial composition can lead to chronic gut inflammation and this chronic inflammation in the gut, has a significant impact on our Gut-brain axis. If you want to know more about this gut-brain axis and how it is a root cause of physical and mental health problems I will leave a link to a video I have done on this.(*)

Tip # 9. Nurse Your Baby and Avoid C-sections.

So what else can we do to improve Gut microbial diversity? If you are a mom or soon-to-be mom, research shows that nursing your baby and avoiding C-sections improves your baby’s bacterial diversity as well as their immune system.

I realize that pharmaceutical companies who manufacture baby formula would want you to believe that powdered milk and formula in a can is just as good as your breast milk. But these are just lies promoted by companies with lots of money to spend on marketing and advertising.

There is nothing better than breastmilk and if you can nurse your baby and avoid C-sections you will be helping your baby. When it comes to breastmilk

Breast milk contains live microbes, immunoglobulins, and a rich supply of oligosaccharides that enrich good bacteria in your baby’s gut. It’s how babies develop passive immunity and build up good bacteria in their guts.
