Alternative to Meds has offered help to clients looking for antipsychotic tapering for over 15 years. Please see our published evidence regarding our success for more information. Underlying issues can in many cases be addressed without toxic prescription drugs. In many cases, we discover that medical conditions were missed or left unresolved, and other contributing factors were overlooked. Tragically, this often resulted in misdiagnoses. We can help.

Research conducted by scientists in various fields suggests that a direct correlation exists between the bacteria in your gut and the neurotransmitters in your brain. Studies show that the foods you eat fundamentally impact the gut microbiome, which helps to regulate your metabolism and immune system, as well as supports brain function by delivering essential nutrients. As a result of this connection, the health of your gut microbiome significantly affects mental health.


What Is the Microbiome?

Within the gut, there are trillions of microorganisms, including bacteria, fungi, protozoa, and viruses of thousands of different species. It’s this busy group of microorganisms in the gut that makes up what’s known as the microbiome. These microscopic “bugs” are mostly found in the small and large intestines but can be located in other parts of the body as well.

The “bugs” that make up the microbiome are a mix of both good and bad, or helpful and harmful critters, and each person has their own individual mix that’s unique to them. A person’s unique combination of microbiota is determined by their DNA and can be affected through the birth process and by their mother’s milk. Later in life, diet, environmental factors, and other conditions can also affect the balance of the microbiome.

Functioning Microbiome

gut microbiome brain connectionWhen the microbiome is functioning as it should, the microbiota helps us to digest our foods and extract the various nutrients that we need from food. The microbiome also enables other essential processes in the body to perform properly, such as eliminating waste, regulating our hormones, maintaining brain health, controlling our emotions, and sending signals to our brain through the neural pathways of the body.

One of these essential processes that our body performs is metabolism. Our metabolism is responsible for how our body breaks down and absorbs nutrients from the food we eat. The gut microbiome is not only responsible for the digestion of these nutrients but the actual metabolic pathways they will go through. So, everything from reading neurotransmitters to sending signals to the brain and a variety of other bodily functions is affected by the microbiome of the gut.

Common Issues in the Microbiome

Because the microbiome is so intricately related to so many different bodily processes and overall health, slight disruptions to the balance of the microbiota can have some consequences for personal health. One example of this is taking antibiotics. These drugs are often prescribed for various infections in the body and help to get rid of the bad bacteria. However, they often also kill off strains of good bacteria living in the gut, making us feel unwell in other ways.

Additionally, many autoimmune disorders, including diabetes, multiple sclerosis, rheumatoid arthritis, muscular dystrophy, and fibromyalgia may all be linked to disruptions in the microbiome. These disorders present themselves when an abundance of disease-causing flora in the gut changes the gene activity and metabolic processes, leading to abnormal responses to body tissues, or what’s known as autoimmune disorders.

The kinds of foods we eat, as well as the prescription drugs we take, and many other environmental factors affect the ability of the trillions of bacteria in the microbiome to carry out these vital processes, ultimately disrupting the signals being sent to the brain to function properly. This is the gut-brain connection that can affect a person’s mental health too.

Understanding the Gut-Brain Connection

A growing body of evidence shows that there is a direct correlation between the gut microbiome and the brain. These two systems communicate through the bacteria in the gut that send signals to the brain through the various metabolic pathways of the body.

Through analyzing the different strains of bacteria in the gut microbiome, research indicates that we can unlock key components to various mental health disorders. According to an article published by Frontiers in Psychiatry in 2020, there are numerous correlations between psychosis and the gut microbiome.

In this study, researchers worked with both people with and without mental illnesses and studied the microbiomes of each group. The findings were that there are stark differences between the bacteria of those with mental illness compared to those without.

Not only were there different kinds of bacteria in each group, but in the group with mental illness, the gut microbiomes showed less varying strains of bacteria than those without mental illness. This can potentially indicate that what we eat and how our gut microbiome can break down food can affect our mental health through the neurotransmitters from the gut to the brain.

So, by possibly adjusting the bacteria and other flora in the gut microbiome, research indicates that we may be able to treat various mental disorders through what we eat, as well as controlling other environmental factors that can affect the microbiota.

Another journal article published in Current Psychiatry Reports supports these findings through data of their own. They found evidence that the gut microbiota is heavily involved in inflammation, the digestion process itself, and gut permeability. The varying degrees of bacteria in the gut influence gluten digestion inefficiencies, of which inflammatory permeability can be a risk factor for Schizophrenia.

Repairing the Microbiome With Diet

What we eat affects everything from how our bodies work to how well they work too. Repairing our body from the inside out starts with the microbiome. This has the potential to reduce the risks of all sorts of diseases and disorders like obesity, diabetes, cancer, heart disease, and mental health conditions.

Choosing to eat foods such as yogurt with active cultures, fiber-rich foods, avocados, nuts, and dark leafy greens, as well as drinking plenty of water all help to create the best environment for your gut microbiome.

Avoid Foods That Can Poison Your Microbiome

Processed foods are what make the bacteria of the gut microbiome work against the body instead of for the body.

To best protect the microbiome, it’s best to avoid overly processed foods as well as the following:

  • Sugars
  • Sodas
  • Simple carbohydrates
  • Candy
  • Chips
  • Fast food

These are the kinds of foods that many people commonly eat every day but are actually making their gut microbiome work more inefficiently. Avoiding eating foods such as these gives the gut microbiome a better chance to thrive and function.

Consider a High Fat Diet

A diet rich in good-for-you fats is great for supporting the gut microbiome environment. Now, this doesn’t mean that it’s ok to just eat fried, high-fat foods. However, foods rich in healthy fats and omega-3s support the microbiome, aid in the digestive processes, and help support brain function, cognition and help to regulate emotions. Healthier fats are key to keeping the brain healthy and promoting mental health.

Add Fermented Foods

Adding fermented foods can be a great way to introduce new bacteria strains to the gut’s microbiome. Fermented foods contain the good bacteria that our bodies need to break down foods and contribute to healthy bodily processes.

Examples of some fermented food to try and add to your regular diet are:

  • Kimchi
  • Kefir
  • Yogurt
  • Kombucha
  • Sauerkraut

These fermented foods help to maintain the balance of healthy gut flora that can contribute to overall physical and mental health.


Consider Holistic Treatment

Nutrition is one easy way to alter the microbiota that make up the gut microbiome. Adhering to a low-carb, keto-based diet is what may be best for the gut microbiome and overall physical and mental health. Eating a diet rich in non-starchy vegetables, ancient grains, and fermented foods can help make the bacteria in the gut microbiome diverse, and this diversity is key in altering the gut-brain connection. Research has shown that following this diet can change the gut microbiome and, in some cases, can successfully put Schizophrenia into remission.

At Alternative to Meds Center, we believe in holistic health and utilize a wide variety of natural health practices for holistic care. We work with you in creating an individualized treatment plan that may involve diet, counseling, yoga, reiki, neurotoxin removal, and many other additional therapies.
