What Causes Microbiome Dysfunction – And How To Optimize The Microbiotica

Exactly what causes microbiome dysfunction is complex, as the human microbiome is a dynamic system of microorganisms that plays an important role in health and well-being. While there are many beneficial microbes that make up the microbiome, when unbalanced, it can lead to dysfunction and poor health outcomes.

The most common causes of microbiome dysfunction are diet, environmental exposures, antibiotic use, stress, and aging. A poor diet that is high in processed foods with little to no fiber can disrupt the gut microbiome and lead to dysbiosis. 

Environmental toxins such as heavy metals, pesticides, and industrial chemicals can also contribute to a disruption in the delicate balance of microbes in our bodies. Antibiotics, while lifesaving in certain instances, can also have a damaging effect on the microbiome. Similarly, chronic stress and aging are known to change the composition of the gut microflora.1

What Causes Microbiome Dysfunction – Diet

Diet has a significant impact on the microbiome. Eating processed foods with limited nutrient content can lead to an imbalanced microbiome. On the other hand, a diet that consists of whole foods such as fruits, vegetables, nuts, grass-fed meat, and grass-fed dairy is beneficial for the diversity and composition of the gut microbiome.2 Additionally, consuming probiotic-rich foods such as yogurt, kefir, sauerkraut, miso soups, and tempeh can support a healthy microbiome.3

Another way to promote a healthy microbiome is to reduce sugar intake. Too much sugar can lead to an overgrowth of harmful bacteria, which can cause inflammation and a weakened immune system.4 Finally, reducing the consumption of alcohol can help balance the microbiome. Research has shown that large amounts of alcoholic beverages can disrupt the beneficial bacteria in the digestive system.5

What Causes Microbiome Dysfunction – Artificial Sweeteners

Artificial sweeteners have been widely used in food and drinks for decades as an alternative to sugar. They are usually much sweeter than normal sugars and contain fewer calories. Although they have traditionally been thought of as a healthier option, recent studies suggest that artificial sweeteners may actually have a negative impact on our intestinal microbiome.

These findings suggest that consumption of artificial sweeteners can lead to an imbalance of the microbiome, and consequently, a disruption of our normal metabolic processes. Studies have found that aspartame, saccharin, and sucralose can cause changes in the composition and diversity of bacteria in the gut. Additionally, research suggests that artificial sweetener consumption is associated with an increased risk of developing metabolic disorders and inflammatory bowel disease.

In fact, Sucralose consumption has recently been associated with developing Leaky Gut Syndrome.6

These worrying findings suggest that artificial sweeteners are not necessarily healthier options and could potentially be contributing to microbiome dysfunction. Therefore, it is important to limit our consumption of these products as much as possible, choosing natural alternatives instead. By doing so, we can help keep our microbiome healthy and balanced for optimal health.7

What Causes Microbiome Dysfunction – Environmental Factors

Environmental factors play a crucial role in the development and maintenance of a healthy microbiome. Unhealthy environments can lead to an imbalance in the composition of beneficial bacteria, leading to dysbiosis or microbiome dysfunction. Factors such as air pollution, water contamination, and soil depletion can cause changes in microbial communities that are detrimental to overall health. Poorly managed agricultural practices can lead to nutrient-poor soil, which can affect the availability of essential nutrients. Toxic exposures to environmental pollutants can also lead to detrimental changes in the microbiome that contribute to disease.8

What Causes Microbiome Dysfunction – Toxic Chemicals

Toxic chemicals are one of the main causes of microbiome dysfunction. Exposure to toxic chemicals such as heavy metals, pesticides, and industrial pollutants can disrupt a person’s microbiome by either killing off beneficial bacteria or enabling pathogenic bacteria to flourish. Studies have also shown that exposure to air pollutants can alter the composition of the gut microbiota and lead to inflammation. Therefore, limiting exposure to toxic chemicals is an important step toward protecting our microbial communities and promoting health.9

Heavy metals are some of the most common environmental pollutants and can wreak havoc on our microbiome. Heavy metals such as lead, mercury, arsenic, chromium, and cadmium often accumulate in soils, water sources, and the air we breathe. When these heavy metals enter our bodies they can create oxidative stress leading to cell death or damage. This cell damage affects not only us but also the bacteria in our microbiome. Heavy metal exposure can lead to an imbalance of beneficial and pathogenic bacteria, causing a dysbiosis of our microbiome.10

What Causes Microbiome Dysfunction – Antibiotic Use

One of the leading causes of microbiome dysfunction is antibiotic use. Antibiotics are a type of medication that is designed to specifically target and kill bacteria, but they can also cause collateral damage to beneficial bacteria in the microbiome. This disruption leads to an imbalance of good and bad bacteria, which can lead to dysbiosis, a condition where the microbiome environment becomes imbalanced and can cause a variety of health issues. 

Additionally, the overuse or misuse of antibiotics can create antibiotic-resistant bacteria, which further exacerbates the issue. To help prevent microbiome disruption from antibiotic use, it is important to only take antibiotics when absolutely necessary and for the full prescribed duration of time.11

What Causes Microbiome Dysfunction – Medications

Medication can cause microbiome dysfunction. Common OTC medications, such as antacids, antihistamines, and corticosteroids can all disrupt the balance of the gut microbiome. Steroid use has been linked to microbiome dysfunction. This is because it suppresses the immune system, which can disrupt the normal microbial balance. 

Steroids are commonly used for a variety of medical reasons, including treating asthma and autoimmune diseases. While they may be beneficial in some cases, long-term steroid use can cause serious side effects, including disruption of the microbiota. This can lead to increased susceptibility to infections, complications from gastrointestinal disorders, and altered nutrient absorption.

Antacids reduce stomach acidity which can have a negative effect on beneficial bacteria growth. Anti-histamines can also reduce the production of gastric acid which can have adverse effects on beneficial bacteria growth. Similarly, some drugs used to treat conditions such as depression, and high cholesterol may alter the composition and functioning of the microbiome.12 13

What Causes Microbiome Dysfunction – Stress

Stress, both physical and psychological, can also lead to dysbiosis. Prolonged or extreme stress causes a cascade of biochemical changes in the body that can suppress immune function, disrupt hormones, and interfere with digestion, all of which can affect the microbial balance in the gut. Additionally, chronic stress is often associated with emotional eating, which can lead to poor dietary choices and further disruption of the microbiome.14

How To Optimize The Microbiotica – Removing Heavy Metals From The Body

One way to remove heavy metals from the body is through chelation therapy, a process that involves administering a chelating agent to bind and remove heavy metals from the blood and tissues. These agents like DMSA and DMPS may be administered orally or intravenously.15 16

How To Optimize The Microbiotica – Consuming Natural Probiotics

The best way to optimize the microbiome is to consume natural probiotics. Probiotics are live microorganisms that, when ingested, provide beneficial bacteria for the gut. They are naturally found in fermented foods and beverages such as yogurt, kombucha, sauerkraut, kefir, and kimchi. These food sources contain high levels of certain probiotic strains that can help maintain a healthy balance of gut bacteria.3

In addition to consuming natural probiotics, it is important to eliminate foods and beverages that disrupt the microbiome. This includes processed foods, refined sugars, artificial sweeteners, alcohol, and other chemicals found in certain food products. Consuming these substances can lead to an imbalance in the gut flora, which can compromise digestive and immune health.

It is also important to consume a variety of nutrient-dense fruits, vegetables, nuts, seeds, grass-fed meat, grass-fed dairy, and healthy fats such as olive oil and avocado. These foods contain prebiotics which are essential for the growth and activity of probiotic bacteria in the gut. Prebiotics feed the good bacteria, helping to optimize the microbiome.17

Finally, getting regular exercise is an important step in optimizing the microbiome. Exercise helps to stimulate gut movement and digestion, leading to better overall digestive health. Additionally, exercise helps to boost the immune system in order to fight off harmful bacteria and infections.18
