How to Improve Your Gut Health & Gut Microbiome Diversity
Reading Time: 17 minutes The human gut is a complex and intricately woven system of trillions of microbes known as the gut microbiota.
These microbes are essential to our overall health, influencing everything from digestion to immunity to mood.
However, the harmony of this delicate ecosystem can be disrupted by factors such as poor diet, lack of sleep, and stress, leading to gut dysbiosis—a state of microbial imbalance.
This article will explore five simple, evidence-based strategies to improve gut health, focusing on dietary, physical, and lifestyle modifications.
Let’s start by learning a bit more about the gut microbiome and how gut health affects your life:
Understanding the Gut Microbiome and How Gut Health Affects You
The gut microbiome, a collective term for the trillions of bacteria and other microorganisms in our gastrointestinal tract, is an integral player in human health and disease.
This dynamic and complex community of microbes not only aids digestion and absorption of nutrients but also plays a central role in various biological functions, exerting a far-reaching influence on our overall health and well-being (Sender et al., 2016).
Here are a few ways your gut health affects your health and well-being.
Digestion and Nutrient Absorption
A healthy gut microbiota facilitates digestion by breaking down complex carbohydrates and proteins that our bodies can’t digest independently.
This breakdown process produces essential nutrients such as vitamins and short-chain fatty acids, which are crucial energy sources for gut cells and contribute to immune function (LeBlanc et al., 2013).
Immune Function
The gut microbiota has a profound influence on the immune system.
Approximately 70% of the immune system resides in the gut, and a healthy, diverse microbiota helps to regulate immune responses, fend off harmful pathogens, and reduce the risk of autoimmune diseases (Belkaid & Hand, 2014).
Mental Health
The gut-brain axis—a bidirectional communication system between the gut and the brain—suggests that our gut health can impact our mental health.
Gut bacteria produce various neurochemicals used by the brain in regulating mental processes such as mood, stress response, and cognitive function, and imbalances in gut microbiota have been associated with several neurological and psychiatric disorders, including anxiety and depression (Mayer et al., 2014).
Weight Management
Gut bacteria play a significant role in regulating body weight.
A diverse and balanced gut microbiota is associated with a healthy body weight and can influence the metabolism of dietary fats, contributing to weight management (Turnbaugh et al., 2006).
Cardiovascular Health
Emerging research suggests that the gut microbiota also affects cardiovascular health by influencing lipid metabolism, blood pressure, and inflammation—factors that can impact heart disease risk (Tang et al., 2017).
Causes of Poor Gut Health
The complexity of gut health is partly due to the number of factors that can negatively impact it.
Though it is often challenging to pinpoint a single causative factor, several elements are typically implicated in poor gut health:
Unhealthy Diet
Diets high in processed foods, sugars, and unhealthy fats, but low in fiber, can compromise gut health by reducing gut microbiota diversity.
Such diets favor the proliferation of pathogenic bacteria at the expense of beneficial gut bacteria, disrupting the delicate balance within the gut microbiota (David et al., 2014).
Chronic Stress
Chronic stress can have detrimental effects on gut health, as long-term stress can cause changes to the gut microbiota and weaken the intestinal barrier, leading to increased intestinal permeability, often referred to as ‘leaky gut’ (Slyepchenko et al., 2017).
Lack of Physical Activity
Sedentary behavior and lack of regular physical activity have been associated with a less diverse gut microbiota, and exercise can improve gut health by enhancing microbial diversity and the production of health-promoting metabolites (Monda et al., 2017).
Insufficient Sleep
Lack of quality sleep can also adversely affect gut health, as sleep deprivation can alter the gut microbiota, disrupt circadian rhythms, and increase intestinal permeability (Voigt et al., 2016).
Overuse of Antibiotics
While antibiotics are crucial for treating bacterial infections, their overuse can lead to antibiotic resistance and long-term changes in the gut microbiota, reducing microbial diversity and leading to an imbalance in the gut ecosystem (Francino, 2016).
Excessive Alcohol Consumption
Excessive alcohol consumption can damage the gut, altering the composition and function of the gut microbiota, impairing the gut barrier, and promoting inflammation (Bishehsari et al., 2017).
Improving gut health requires addressing these factors through lifestyle modifications, such as adopting a healthier diet, managing stress, increasing physical activity, ensuring adequate sleep, and using antibiotics responsibly.
Signs & Symptoms of Poor Gut Health
Recognizing the signs of poor gut health is a crucial step toward taking action to improve it.
Your gut health is intrinsically linked to your overall well-being, and an imbalance in your gut microbiota can lead to various negative health effects, signs, and symptoms.
If you notice any of the following symptoms persistently, it might indicate that your gut health needs attention:
Digestive Issues
The most obvious signs of poor gut health are digestive problems. These can include:
- Bloating: This might be due to excess gas production by the bacteria in your gut.
- Constipation or Diarrhea: Changes in bowel habits can indicate an imbalance in your gut bacteria.
- Acid Reflux or Heartburn: This can occur when stomach acid backs up into your esophagus, potentially due to an imbalance in your gut microbiota.
Unintended Weight Changes
Both weight loss and weight gain that occur without changes in your diet or exercise habits could be a sign of gut dysbiosis.
Certain types of bacteria in the gut can affect the absorption of nutrients, influence fat distribution, and promote feelings of hunger or fullness.
Fatigue or Poor Sleep
There’s a strong connection between your gut and your brain, often called the gut-brain axis. Serotonin, a hormone that affects mood and sleep, is primarily produced in the gut.
Therefore, an unhealthy gut might result in sleep disturbances or chronic fatigue.
Skin Irritations
Skin conditions such as eczema may be related to a damaged gut.
Inflammation in the gut due to poor diet or food allergies could cause “leaky gut” — where proteins leak out into the body, which can irritate the skin and cause conditions like eczema.
Autoimmune Conditions
Scientific research suggests that poor gut health may influence immune system function and contribute to autoimmune diseases, where the body attacks itself rather than harmful invaders.
Food Intolerances
Food intolerances are believed to be caused by poor-quality of gut bacteria.
This can lead to difficulty digesting certain foods and unpleasant symptoms such as bloating, gas, diarrhea, abdominal pain, and nausea.
If you are experiencing these symptoms regularly, consulting a healthcare professional might be a good idea.
They can guide dietary and lifestyle changes or, if needed, further medical treatments to improve your gut health.
7 Effective Tips for Improving Your Gut Health
Remember, a healthy gut contributes to a strong immune system, heart health, brain health, improved mood, healthy sleep, and effective digestion.
By maintaining a healthy gut, you’re ensuring your body’s overall health and well-being.
1.) Add Probiotics and Prebiotics to Your Diet
A healthy gut microbiota is crucial for overall health, and one of the best ways to support and improve this is by consuming probiotics and prebiotics.
These beneficial dietary components interact with our gut microbiota to improve gut health and influence our overall health.
Probiotics
Probiotics are beneficial live microorganisms that, when consumed in adequate amounts, can confer a health benefit to the host.
They have been extensively researched and are well-recognized for their role in promoting a balanced gut microbiota (Hill et al., 2014).
Food Sources of Probiotics
Fermented foods are the best dietary sources of probiotics. These include foods such as:
- Yogurt: Perhaps the most popular probiotic food, look for “live and active cultures” on the label to ensure you’re getting beneficial bacteria.
- Sauerkraut: This fermented cabbage dish is a great source of probiotics and is rich in fiber and vitamins A, C, and K.
- Kefir: A fermented milk drink, kefir contains a wider variety of probiotic strains than yogurt and is naturally lower in lactose, making it suitable for a wider range of individuals.
- Kombucha: Kombucha contains a handful of beneficial bacteria strains and is rich in antioxidants.
Probiotic Supplements
While food sources are the best and most natural way to get probiotics, some people may benefit from supplements.
For instance, Garden of Life Dr. Formulated 3-in-1 Complete Probiotic, Prebiotic & Postbiotic is an excellent choice, offering a variety of probiotic strains.
However, before starting any new supplement, it’s essential to discuss it with a healthcare provider, as individual health needs may vary.

Prebiotics
Prebiotics are a type of dietary fiber that acts as food for our beneficial gut bacteria.
By consuming prebiotics, we can promote the growth and activity of these beneficial bacteria, supporting a diverse gut microbiota (Slavin, 2013).
Food Sources of Prebiotics
Prebiotics are found in a variety of whole foods. Some of the best sources of prebiotic fiber include:
- Onions and Garlic: These versatile cooking ingredients are rich in prebiotic fibers that feed beneficial bacteria.
- Bananas: Besides being a good potassium and vitamin B6 source, bananas are rich in a prebiotic fiber called inulin.
- Oats: A hearty source of beta-glucan, oats contain a type of fiber with potent prebiotic properties.
- Apples: Apples contain pectin, a fiber that acts as a prebiotic and promotes the growth of beneficial Bifidobacteria in the gut. Green apples tend to contain slightly more nutrients than red apples.
Prebiotic Supplements
While consuming prebiotic foods is the best and most natural way to intake prebiotics, there are effective prebiotic supplements available.
Hyperbiotics Vegan Organic Prebiotic Powder is an excellent choice for those interested in supplementation, but consulting with a healthcare provider before starting a new supplement is crucial, as with probiotics.

2.) Maintain a Diverse Diet
A diverse diet is not just about ensuring a spectrum of nutrients for your body; it directly influences the diversity of your gut microbiota.
Our gut is inhabited by trillions of microorganisms, including bacteria, fungi, and viruses, that form an intricate ecosystem known as the gut microbiota, and each of these microorganisms has a unique set of dietary preferences.
Therefore, the more varied our diet, the more diverse our gut microbiota can be, and a diverse gut microbiota is important because it is associated with better overall health.
Research has found that decreased diversity in gut bacteria is linked with various health issues, including obesity, inflammatory bowel disease, and even certain mental health conditions.
To foster a diverse and robust gut microbiota, focus on incorporating a broad array of foods in your diet, such as:
- Fruits and Vegetables: Aim to consume a rainbow of fruits and vegetables, as each color represents a different set of beneficial phytonutrients that can feed various bacteria in the gut.
- Whole Grains: Whole grains like brown rice, quinoa, oats, and barley are excellent sources of dietary fiber. They not only help in digestion but also promote the growth of beneficial gut bacteria.
- Legumes: Foods such as beans, lentils, and peas are rich in fiber and protein and can stimulate the growth of beneficial bacteria while suppressing harmful ones.
- Nuts and Seeds: Nuts and seeds are a rich source of fiber, healthy fats, and antioxidants which can support gut health.
- Fermented Foods: Including fermented foods such as yogurt, sauerkraut, and kimchi in your diet can help introduce beneficial bacteria to your gut and enhance its diversity.
Lastly, remember to keep rotating your food choices.
If you eat the same foods every day, you’re only feeding the same set of gut bacteria, which may limit the diversity of your gut microbiota.
Strive for variety in your meals to provide a wide range of nutrients and fibers that can foster a diverse and robust gut microbiota (Holscher, 2017).
3.) Engage in Regular Physical Activity
Regular physical activity has been widely recognized for its host of health benefits, including cardiovascular health, weight management, and mental well-being.
However, emerging research suggests that exercise also plays a critical role in maintaining and improving gut health.
The Gut-Exercise Connection
Exercise can favorably alter the composition and functionality of gut microbiota.
It has been found to increase the diversity of gut bacteria, an indicator of gut health, and enhance the production of health-promoting short-chain fatty acids (SCFAs) (Mailing et al., 2019).
SCFAs such as acetate, propionate, and butyrate are end products of gut bacteria fermentation of dietary fibers, and they serve several crucial roles in maintaining gut health.
Here are a few of the roles they play in our overall health:
- Energy Source: SCFAs are the primary energy source for the cells lining the colon, helping maintain the integrity of the gut lining.
- Anti-inflammatory Properties: SCFAs have been shown to possess anti-inflammatory properties, which can help manage inflammatory conditions in the gut.
- Appetite Regulation: They also influence hormone levels, affecting satiety and appetite regulation.
Therefore, by promoting SCFA production, regular physical activity can profoundly impact gut health.
How Much Exercise Do You Need?
While any amount of exercise is better than none, health guidelines generally recommend at least 150 minutes of moderate-intensity or 75 minutes of high-intensity aerobic activity each week, along with strength training exercises on two or more days a week.
However, the type and intensity of exercise that would optimally benefit gut health is still an active research area.
Incorporating Exercise Into Your Normal Routine
Starting an exercise routine can feel daunting, but it doesn’t have to be complicated. Here are a few tips to make it easier:
- Find activities you enjoy: You’re more likely to stick with a routine if you enjoy the activities. This could be anything from dancing to cycling to yoga.
- Start slow and gradually increase: If you’re new to exercise or getting back into it, start with small amounts and slowly increase your activity levels as your fitness improves.
- Incorporate movement into your day: Take the stairs instead of the elevator, go for a walk during lunch breaks, or have “walking meetings” instead of sitting.
Regular physical activity is a potent tool for promoting gut health, along with its numerous other health benefits.
4.) Limit Intake of Artificial Sweeteners
While pursuing a healthier lifestyle, many of us might turn to artificial sweeteners as a substitute for sugar.
They’re often used in “sugar-free” or “diet” foods and drinks with the intention of reducing calorie intake.
However, research indicates that these sweeteners might not be as beneficial as they appear, particularly regarding gut health.
Artificial Sweeteners and the Gut Microbiota
Artificial sweeteners, such as aspartame, sucralose, and saccharin, have been found to alter gut microbiota composition and function.
They can decrease the diversity of the gut microbiota and affect its metabolic functions, which might subsequently influence glucose metabolism, amongst other negative effects (Suez et al., 2014).
This disruption of gut microbiota, known as dysbiosis, has been linked to several health issues, including inflammatory bowel disease, obesity, and type 2 diabetes.
Natural Sweeteners as an Alternative
For a healthier gut, limiting the intake of artificial sweeteners is advised.
However, this doesn’t mean you have to completely cut out sweetness from your diet.
Natural sweeteners like raw honey, maple syrup, or coconut sugar are good artificial sweetener and sugar alternatives that are sweet and come with additional nutrients and antioxidants.
However, it’s essential to remember that even natural sweeteners should be consumed in moderation, as excessive consumption can lead to increased caloric intake and potential health problems.
Even better than natural sweeteners are fruits.
Fruits not only provide natural sweetness, but they’re also packed with essential vitamins, minerals, antioxidants, and dietary fiber.
The fiber in fruits can act as a prebiotic, feeding your gut bacteria and helping to maintain a healthy and diverse gut microbiota.
For optimal gut health, consider reducing the intake of artificial sweeteners and opt for natural sweeteners or fruits when a sweet craving hits.
5.) Prioritize Good Sleep and Stress Management
The gut is not an isolated organ but an integral part of a complex system where various factors, such as sleep and stress, can significantly influence its health.
Therefore, focusing on good sleep and stress management is just as essential as dietary considerations for maintaining a healthy gut microbiota.
Sleep, Stress, and the Gut
Both lack of sleep and chronic stress can disrupt the gut microbiota, creating an imbalance known as dysbiosis.
Dysbiosis can lead to various health issues, including digestive problems, obesity, and mood disorders., and ensuring adequate, quality sleep and managing stress effectively are key to promoting a healthy gut environment (Sanada et al., 2020).
Tips for Good Sleep Hygiene
Good sleep hygiene involves practices and habits necessary for good nighttime sleep quality and full daytime alertness. Here are some tips:
- Establish a Regular Sleep Schedule: As much as possible, go to bed and wake up at the same time every day, even on weekends. This can help regulate your body’s internal clock, making it easier to fall asleep and promote better sleep quality.
- Create a Restful Environment: Keep your sleep environment quiet, dark, and cool. Consider using eye shades, earplugs, or a brown noise machine if needed.
- Limit Exposure to Screens Before Bed: The light emitted by phones, tablets, computers, and TVs can interfere with your sleep. Try to turn off these devices at least an hour before bedtime.
Stress Management Practices
Incorporating stress management practices into your routine is crucial for gut health.
- Meditation: Regular meditation can reduce stress, promote relaxation, and enhance overall well-being. Even a few minutes each day can make a difference. Mindfulness-based stress reduction, a type of meditation, has been found to positively affect gut health.
- Breathing Exercises: Simple breathing exercises can also help reduce stress and promote relaxation. I use the app BreathWrk, which offers various guided breathing exercises to help manage stress.
6.) Adding a Colostrum Supplement to Your Diet
Colostrum, often referred to as “nature’s first food,” is the nutrient-rich, milky fluid produced by mammals in the first few days after giving birth.
It is packed with bioactive compounds, including immunoglobulins, growth factors, and probiotics, making it a powerful supplement for improving gut health.
How Colostrum Benefits Gut Health
Colostrum has been shown to support gut health in several ways. It strengthens the gut lining, preventing or alleviating conditions like leaky gut syndrome, where the intestinal barrier becomes permeable.
Additionally, colostrum helps replenish beneficial gut bacteria, supporting microbial diversity and fostering a balanced microbiome.
Its anti-inflammatory properties can also reduce gut inflammation, aiding in the recovery of digestive disorders.
