Run your tongue over your teeth. If it’s been a while since your last brushing, you might detect a slick film coating your pearly whites. Your dentist calls the film plaque, but the greater scientific community would call it a biofilm.
You can have similar films in the digestive tract, ears, and inside vital organs. And it turns out that biofilms can be prime breeding grounds for microbial infections, chronic fatigue, autoimmune diseases, inflammatory diseases, and more.
What are biofilms?
According to the Center for Biofilm Engineering at Montana State University, biofilms take shape when bacteria in moist environments adhere to surfaces by secreting a glue-like substance. This occurs on non-living materials such as metal and plastic (e.g. the slimy film coating a sink drain or shower curtain), but they also form on living tissues.
Think of biofilms inside the body as microbial bomb shelters. A construction of sugars and proteins, biofilms are designed to protect organisms from the onslaught of your immune system and any antimicrobial compounds you take to get rid of the living inhabitants.
If left to accumulate, the matrix that anchors biofilms to your organ systems gets stronger over time and begins to attract other microbes and toxins into the protective lair.
What starts as a small gang of pathogenic bacteria can become the breeding ground for invasive fungi, parasites, and viruses. A diverse biofilm also makes a great hiding place for environmental toxins and heavy metals. (1)
Organisms growing and reproducing within the biofilm matrix can become more resistant to antibiotics and the immune system. Normally, a healthy immune system seeks out to destroy single pathogens with an arsenal of immune secretions. But a protected biological mass under a biofilm may not signal the immune system of a possible threat. And any attack waged by immune cells has to make it through the tough biofilm shield to target the pathogens.
So you can see the potential problems if we just let biofilms be.
Biofilms incubate disease
Dental biofilms are associated with gum disease - no shocker there. Further into the body, biofilms have been identified as the root cause of ear infections and urinary tract infections. (2)
Inside the digestive tract, unhealthy biofilms are linked to the following GI diseases: GERD, parasitic infections, Candida yeast overgrowth, IBS, ulcerative colitis, and Crohn's disease. (3)
How do you get rid of biofilms?
Since biofilms are constructed from sugars and proteins, your best bet is to hit them hard with compounds that break apart those building materials. Enzymes that specialize in breaking down sugars and proteins can make a significant impact.
You may already have digestive enzyme supplements that you can use for biofilm clean up. When you take digestive enzymes with meals, enzymes speed up the dismantling of food in your stomach. When you take enzymes between meals on an empty stomach, they can spend time on systemic healing tasks such as inhibiting inflammation and destroying the protein-based protective shields around bacteria, viruses, yeast, fungi, and food allergens.
Some enzymes don’t take kindly to acidic environments. Taking enzymes between meals when the stomach is more alkaline limits their chance of being destroyed or inactivated as they pass through the stomach and move on to the intestines for absorption.
Even if cleansing biofilms isn’t a priority for you, there are benefits galore to taking protein digesting proteolytic enzymes (proteases, beta-glucanase, bromelain, papain). You're bound to find a few useful:
Herbs that have shown promise in breaking through the tough biofilm matrix include cloves and false black pepper (Embelia ribes).
To further your biofilm cleansing efforts, it’s also important to supply the gut with the right in kind of organisms - probiotics. These good bacteria help to create a healthy intestinal biofilm, one that provides appropriate lubrication (so things slide through easier) and anti-inflammatory qualities.
Remember, a healthy gut has system-wide benefits.
