The human gut microbiome is a mystery to most people, and rightly so. The gastrointestinal system is complex, bustling with trillions of microorganisms, including bacteria and individualized genetic information. Unbeknownst to us, these microorganisms are rumbling away, performing their daily functions and activities to keep our guts in good health.

The Microbiome: A Closer Look Under the Microscope

So what is a microbiome, exactly? Simply put, it is a community of microorganisms, or microbiota, living in a particular habitat. When we refer to our gut microbiome, we talk about the organisms that live inside our gastrointestinal tract. From bacteria to viruses to fungi, there are hundreds of unique species inside us, some beneficial and others harmful. We play host to entire ecosystems and are never any the wiser.

What are MDFs?

Although our bodies maintain gut health as a natural human function, our habits are critical for shaping it, especially when it comes to our diet. Gastrointestinal microbes sustain themselves through the foods we eat, so our diet fundamentally affects the makeup of our gut microflora. The nutrients we consume enable the growth and diversification of microbiota. As the saying goes, we truly are what we eat!

Enter Microbiome-Directed Foods or MDFs. These are foods that are specifically targeted towards improved gut health, intended to selectively promote the growth of beneficial microbes associated with good health. Recent studies have shown that MDF can significantly support the nutritional needs of malnutrition kids (1-2).

A Gut Feeling- How the Gut Microbiome Influences Health and Immunity?

It’s only recently that scientists have discovered the relationships between gut health, immune response, diet, and disease. They found that our gut health is inextricably tied to our body’s microbial ecosystems and has a significant impact on our overall health.

Your body’s microbiome composition can be linked to an array of diseases, including neurological and sleep disorders, IBS, autoimmune disease, and obesity. Your gut microbiome impacts your overall health, but it is also closely tied to your immune system and its ability to fight off chronic disease – and that this is just the tip of the iceberg.

Why it’s important to go with your gut?

Why should you care about the microorganisms that live in your GI tract? They’re getting the job done, so do you really need to do anything about it? The answer is yes! Since your gut health is so deeply interconnected with your overall health and immune system, there’s no good reason to neglect this aspect of your wellbeing.

Treat your microbiota right by carefully choosing what you put into your body. A resilient gut microbiome can drastically impact your health, which is why personalized nutrition can be an incredible first step towards taking control of your wellbeing. This is what makes MDFs a game-changer.

Biom Probiotics are an innovative MDF supplement, specially designed to positively modulate gut flora. They feature microbiome accessible carbohydrates (MACs), which have been found to reduce the microbial imbalance in the gut.

Biom supplements utilize dietary fibers like prebiotics and polyphenols, which are resistant to digestion, making them immediately available for metabolization and fermentation by gut flora. These metabolic processes encourage the growth and function of healthy gut bacteria and promote better overall health. A healthy microbiome plays a critical role in maintaining your body’s health and longevity.


In conclusion, Biom Probiotics are a safe and trusted way to stabilize, diversify, and nourish your gut and improve your health. Because when your gut is happy, your whole body thrives! To learn more, reach out today.

Frequently Asked Questions

What are the beneficial foods for the microbiome?

Beneficial foods for the microbiome, also known as Microbiome-Directed Foods (MDFs), include fibrous foods, fermented products, and foods rich in polyphenols. These nourish the gut microbiota, promoting a healthy, diverse ecosystem.”

How do MDFs interact with the human gut microbiome?

MDFs interact with the human gut microbiome by providing the necessary nutrients for beneficial microbes to thrive. These nutrients include dietary fibers and microbiome accessible carbohydrates (MACs), fostering a balanced and healthy gut environment.”

Are MDFs safe for everyone to consume?

Yes, MDFs are generally safe for everyone to consume as part of a balanced diet. However, individuals with specific dietary needs or medical conditions should consult their healthcare provider before making significant dietary changes.”

What are the potential side effects of consuming MDFs?

While MDFs are generally safe, potential side effects might occur due to changes in gut flora. These can include temporary digestive discomfort as the microbiome adjusts to the new dietary components. Always consult with a healthcare provider if you have concerns.
