Testing Your Gut Part 1: Saliva Test

Photo from amherstpediatrics.net

Each of us has a remarkable immune paint that coats the surface of the gut barrier so foreign substances cannot enter. This remarkable paint is secretory immunoglobulin A (IgA).  Secretory IgA is the most abundant class of antibodies found in the intestines of humans.  This immune paint exists on all body surfaces that come into direct contact with the outside world from your nose to your anus, your tear ducts and nipples to the tube you pee out of.  Secretory IgA is an amazing protection; it is our first line of defense.

Its’ defense is against viruses, parasites, bacteria and fungus.  This barrier paint also protects against toxins such as heavy metals (mercury, lead, etc.) and unwanted chemicals like pesticides and herbicides.  Secretory IgA and mucous creates a protective slime that sticks to the gut lining and creates a wall of protection.

So why does this matter, and what can you do about this?

Well you need a health professional who knows about this immune paint, also known as a marker. That could be your doctor, a physician assistant or nurse practitioner. They can order a simple saliva test that you collect in the comfort of your own home.  This test will reveal if your immune paint is working or not. If it is not you are susceptible to infection.

To fix this issue I prescribe a pill or powder used in the medical community, known as L-Glutamine that will restore your immune paint over time.  I prefer the powder because the body has less stress in absorbing a powder.  It will take at minimum 3 months to fix this issue.

It is rare that an individual has an adequate secretory IgA level in today’s high stress society.   If you have lower levels it could be related to high stress in your life, a disruption in your sleep wake cycles and the presence of food allergies. Because it is so rare to have enough of the secretory IgA in your body it is more important now than ever that people know about this test and ask for it!

Tune in next week for part two of the “Testing Your Gut” miniseries!

Our Soup of Bugs: Promoting Good Gut Bugs Prebiotics and Probiotics

There is a lot of talk nowadays about probiotics. What the heck are they?  Well we learn a little about probiotics during a television commercial with a yogurt product called Activia which claims to help populate your gut with good bacteria. If it could be so simple!  Did anyone say our current diet could be eroding the good bacteria? No! Anyway, probiotics are the first step in being aware and empowered in our gut health and integrity.

Probiotics are beneficial bacteria that flourish in your digestive track but they require a balanced pH (potential hydrogen) environment to stick around. Some voices would argue they do not stick around but wash out.  They help your body digest nutrients, absorb vitamins, stop inflammation and stop the growth of bad bacteria. Bad bacteria are classified as anaerobic bacteria. If these bad bacteria are left unchecked your food will not digest like it should but will ferment and produce toxins. You will have discomfort, gas and bloating. After eating you will feel bad.  Yuck!

Maintaining the friendly bacteria in the GI tract is paramount to good health. In order for the small intestines to work properly, it is important to nourish this tissue with an ample supply of friendly bacteria called probiotics.  Probiotics are live microorganisms that when eaten in adequate amounts as part of food intake support the host’s health.  Some individuals call probiotics the “ultimate neighborhood watch” as they are continually keeping guard against harmful bacteria, parasites and other pathogens that want to rob our health.

Probiotics are the active participants in a wide range of health promoting mechanisms in the GI tract. Probiotics support health cell growth, maintain the gut barrier, build the cell wall, reduce inflammation, stop pathogen adhesion and enhance the immune system. Our diet profoundly affects the gut flora just as it affects the rest of our health.  A diet high in sugar and starches such as flour-containing foods limit probiotics’ growth.  However, a vast array of plants we can eat will encourage the growth of healthy intestinal flora.  While probiotics are the healthy bacteria, prebiotics are the foods that feed them.

A prebiotic is a nondigestable food ingredient that positively affects the growth and activity of bacteria in the colon and improves over all health13.   Examples of prebiotics are disaccharides, polysaccharides and oligiosaccharides.  These are complex carbohydrates that migrate to the colon where they are selectively fermented by specific bacteria. This fermentation process stimulates the growth and activities of other bacterial species that already reside in the colon.

The probiotic prebiotic phenomena creates a chain reaction whether in the small intestines or colon by releasing a vital short-chain fatty acid called butyric acid (butyrate) that improves gut function and promotes an anti-inflammatory response in the GI tract.  Short chain fatty acids are the ideal fuel for the epithelial cells that line the gut, nurturing them to ideal health and function.  Supplements nowadays can contain both probiotics and prebiotics called “Synbiotics.”

An ideal way to maintain proper gut flora is using a synbiotic that is from soil-based organisms.  When we talk about maintaining good gut flora over the long term for optimal function and graceful aging this combination shows promise.  Who would of thought we are made up of a soup of bugs and that we need to be proactive in maintaining the good gut bugs and not the bad?
