We are super-organisms! Home to a community of 38,000,000,000,000 (that's 38 trillion) bacteria including some fungi, protozoa, and viruses - also known as 'microbes.' Each one of us is an ecosystem with microscopic organisms living in and on us. These microbes outnumber our own human cells by 300 times. Yes! We are more bacteria than humans! Surprisingly, the majority of these microbes find their home in our gut.

This is why these live bacteria have a major effect on our systemic health and have been implicated in many disorders, such as allergies, irritable bowel syndrome (IBS), asthma, metabolic syndrome, cardiovascular disease, obesity, and more! (1)

We are now acknowledging that our gut health extends beyond healthy digestion. Our gut health regulates our mood (through serotonin production) - hence, mental health and relationships, immune response, and predisposition to weight gain.

Having established the crucial role of the microbiome in our well-being and immune system, let's delve into how these microbial communities can be altered and the consequences that ensue.

Factors that alter our gut microbiome and can reduce immune function

Antibiotics

Antibiotics work by killing bacteria. This is effective when you’re sick and need help fighting off “bad” bacteria, but in accomplishing this, they also tend to destroy the “good” bacteria. Even one dose of a commonly prescribed antibiotic can diminish microbial diversity for up to one month. (2) And, although antibiotics can be necessary at times, it's crucial to remember to give our gut some extra love during and after the treatment.

Pain medication - NSAIDS

NSAIDs induce gastrointestinal damage (3)

Stress levels

Brief periods of stress have been shown to alter the gut microbiota. (4)

Diet & Alcohol consumption

Diet has a profound impact on the types of bacteria that thrive. A small dietary change has been shown to alter your gut microbiota. (5) Diets that are plant-based are especially supportive of the beneficial organisms in the gut. (6)

Birth history (C-section vs. vaginal birth)

Babies born via C-section are exposed to different strains of bacteria as compared to babies born vaginally.

Diet during infancy

Breastfed infants are exposed to more beneficial bacteria from their mothers than formula-fed babies.

Age

It takes up to three years for toddlers to colonize their gut microbiome similar to that of an adult. Microbial diversity may also decrease after age 75. (7)

Genetics

Although much of our gut health has to do with environmental factors, some aspects of the microbiome may actually be inherited. (8)

So, what happens when we introduce said factors? Our gut bacteria can be thrown out of balance, having the "bad" bacteria outnumber the "good." It’s okay when it’s once in a while, but when the exposure to irritants through diet and environment becomes constant, it compromises the integrity of the gut lining, causing chronic inflammation, which leads to a variety of disorders.

What is inflammation?

Glad you asked. It’s the body’s natural response to injury, infection, or irritation. A protective mechanism that helps the body heal by fighting off harmful pathogens, but it can also contribute to a range of health problems if left untreated; it can become chronic or excessive.

So, when our immune system feels threatened and needs to protect itself, it will elicit an immune system response.

What is an allergy?

The immune system responds to a substance that is normally harmless, such as pollen, animal dander, or certain foods. When a person with an allergy is exposed to an allergen, their immune system reacts by producing antibodies, which can trigger the release of chemicals such as histamine (a chemical released by white blood cells into the bloodstream when the immune system is defending against a potential allergen). These chemicals can cause a range of symptoms, including inflammation, swelling, itching, and redness.

What happens when the immune system is constantly having to defend itself? Then, the body’s natural defense system can’t tell the difference between its own cells and foreign cells, causing the body to mistakenly attack normal cells. This is an autoimmune disease.

Is it all starting to make sense?

Everything is connected

An autoimmune disease is a condition in which the immune system mistakenly attacks the body's own cells, tissues, or organs, recognizing them as foreign or harmful. In a healthy immune system, specialized cells and proteins work together to defend the body against harmful pathogens, such as bacteria and viruses. However, in autoimmune diseases, this defense mechanism malfunctions, leading to the immune system targeting normal, healthy cells.

The gut plays a significant role in the development of autoimmune diseases through a phenomenon known as "leaky gut" or increased intestinal permeability. The lining of the gastrointestinal tract acts as a barrier, selectively allowing nutrients to pass into the bloodstream while keeping harmful substances, such as bacteria and toxins, out. However, in certain circumstances, this barrier can become compromised, leading to increased permeability.

When the gut barrier is compromised, it allows the entry of substances that are not normally permitted to pass through. This includes bacteria, toxins, undigested food particles, and other antigens. These foreign substances can trigger an immune response in individuals who are genetically susceptible to autoimmune diseases or who have an underlying dysregulation of the immune system.

As the immune system encounters these foreign substances leaking from the gut, it may react by producing antibodies and mounting an inflammatory response. In some individuals, this immune response becomes dysregulated and starts to recognize certain components of the body's own tissues as foreign. This phenomenon is called molecular mimicry, where the antigens from the gut leakages resemble the body's own antigens, leading to confusion within the immune system.

Once the immune system starts attacking its own tissues, the process of autoimmunity begins. Depending on the specific autoimmune disease, various organs or tissues can be affected. For example, in rheumatoid arthritis, the immune system primarily targets the joints, leading to inflammation, pain, and joint damage. In multiple sclerosis, the immune system attacks the protective covering of nerve fibers in the central nervous system.

Research has unveiled the remarkable influence of the gut-brain axis on numerous facets of health, shedding light on its pivotal role in the development and progression of serious conditions, particularly cognitive decline, and dementia. (11) The gut-brain axis represents a bidirectional communication pathway between the gastrointestinal tract and the brain, where intricate signaling mechanisms take place. Emerging studies have demonstrated that disruptions in the gut microbiota composition and imbalances in gut barrier function can have far-reaching consequences, impacting brain health and cognitive function. Imbalances in the gut microbiome, characterized by reduced microbial diversity or the proliferation of harmful bacteria, have been associated with neuroinflammation, oxidative stress, and the accumulation of abnormal proteins in the brain, all of which are implicated in cognitive decline and the onset of dementia. Hence, chronic inflammation originating from the gut can initiate a cascade of events that contribute to neurodegeneration and cognitive impairment.

According to a study, the prevalence of autoimmune diseases and allergies is increasing - roughly 50 million Americans are currently diagnosed with an autoimmune disease. (9) Allergic disorders, such as anaphylaxis, hay fever, eczema, and asthma, now afflict roughly 25% of people in the developed world. (10)

Embracing an Integrated Approach

So, how can we support our gut health and overall well-being?

Nutrition

Stick to Whole Foods: Opt for minimally processed foods that are as close to their natural state as possible. Whole foods, such as fruits, vegetables, whole grains, lean proteins, and healthy fats, provide essential nutrients and support optimal physical and mental health, including a healthy gut microbiome.
Eat a Variety of Foods: Embrace a diverse range of foods to ensure you receive a broad spectrum of nutrients that promote gut health. Incorporate colorful fruits and vegetables, whole grains, legumes, nuts, seeds, and lean proteins into your meals. This diversity supports the growth of different beneficial bacteria in your gut.
Incorporate Prebiotic and Probiotic-Rich Foods: Enhance your gut health by including foods rich in prebiotics and probiotics. Prebiotics, such as onions, garlic, bananas, asparagus, and whole grains, act as nourishment for beneficial gut bacteria, helping them thrive. Probiotic-rich foods, like yogurt, kefir, sauerkraut, kimchi, and other fermented foods, introduce live beneficial bacteria to your gut, contributing to a healthy gut microbiome.
Hydrate: Proper hydration is essential for overall health, including a healthy gut. Drink an adequate amount of water throughout the day to stay hydrated and support optimal bodily functions, including digestion and nutrient absorption. Limit the consumption of sugary drinks and alcohol, as they can disrupt the balance of gut bacteria.
Consume Enough Fiber: Fiber plays a crucial role in digestive health and supports a healthy gut environment. Include fiber-rich foods such as whole grains, legumes, fruits, vegetables, and nuts in your diet. These foods promote regular bowel movements, help maintain gut barrier function, and support the growth of beneficial bacteria.
Listen to Your Body: Recognize that everybody is unique, and there is no one-size-fits-all approach to nutrition for gut health. Pay attention to how different foods make you feel and make choices that align with your individual needs and preferences. Practice mindful eating by tuning in to your body's hunger and fullness cues, and strive for a balanced and intuitive approach to nourishing your gut.

Manage your stress

Mindfulness and Meditation: Cultivate present-moment awareness through meditation and mindfulness practices. These techniques promote relaxation, reduce anxiety, and enhance overall well-being.
Move your body: Engage in regular physical activity to release endorphins, boost mood, and reduce stress. Choose activities you enjoy, such as yoga, walking, dancing, or any form of exercise that gets your body moving.
Deep Breathing and Relaxation Techniques: Practice deep breathing exercises, progressive muscle relaxation, or guided imagery to calm your mind and release tension in your body.
Social Support: Connect with loved ones, friends, or support groups to share your feelings, and experiences, and seek guidance. Social support can provide a sense of belonging and help alleviate stress.
Self-Care Practices, Spend time outside: Dedicate time for self-care activities that bring you joy and relaxation. This can include hobbies, creative pursuits, spending time in nature, taking a soothing bath, or engaging in activities that recharge your energy.
Try journaling; is more than just putting pen to paper; it's a powerful tool for enhancing our well-being. By journaling, we can gain clarity, express emotions, reduce stress, and improve our mental and emotional health. It's like having a personal therapist in the form of a notebook, helping us navigate life's challenges and fostering self-reflection and personal growth.
Seek Professional Help: If stress becomes overwhelming or persists despite your efforts, consider seeking support from a mental health professional. They can provide guidance, therapy, or other interventions tailored to your specific needs.

Supplements

The Western diet is proven to be the primary contributor to the increasing rates of inflammation and disruptors to a healthy gut. Thus, a combination of probiotics and prebiotics as part of a whole-food diet can help achieve the right balance of gut bacteria to support health and reduce inflammation. My personal favorite is Seed, but always research which is best for you!

Sleep

Restorative sleep is crucial for gut health since it plays a vital role in maintaining a balanced gut and managing allergies, inflammation, autoimmune disorders, and even dementia. Quality sleep promotes the balance of gut bacteria, regulates immune responses, reduces inflammation, and supports brain health and cognitive function. By prioritizing restorative sleep, you can enhance your body's natural healing mechanisms and potentially reduce the risk or severity of these interconnected conditions.

Supporting Gut Health for Overall Well-being

Although ongoing research continues to reveal the intricate link between an imbalanced gut microbiome and declining health, our understanding of an integrated approach to gut health is clearer than ever. By prioritizing nutrition, stress management, physical activity, supplements, and restorative sleep, we can actively support a healthy microbiome and reduce the risk of these interconnected conditions. Embracing this comprehensive approach to health is essential for promoting long-term well-being and vitality. Remember, a healthy gut is the foundation for a healthy life.
