“The immune system present in the gut makes more immunological decisions in a day than the rest of the immune system does in a lifetime”.  (1)

If your immune system isn’t behaving itself properly, you might want to consider that your digestive system is the culprit.

Your digestive system has a special mucosal lining over the surface of your intestines, and the health of your gut flora (the complex, extremely important colony of bacteria within your digestive system, also known as the microbiome) has a huge amount of immune decisions to make on a daily basis – it has to deal with bacteria, viruses and food, and decide each time whether it is a friend or foe.

Setting up the gut bugs

The bacteria within your gut are established within the first 20 days of life.  If the bacterial colony does not set up adequately, babies can be immune compromised and can be more prone to immune imbalances later on in life, as well as increased inflammation which is largely controlled by our immune cells.

Frequent use of antibiotics can severely impact on the health of your digestive system.  In some cases, certain bacteria can never recover after they have been killed by antibiotics (2).

The gut reports to the immune system

There is a special type of cell within the digestive system called a dendritic cell.  This cell is responsible for determining whether our immune system should be on high alert or not.  Occasionally this cell will extend a little feeler (almost like a tentacle) and take a handful of whatever is in your digestive system to examine, to then report back to the rest of the immune system whether everything is okay or not.  This can explain why your diet can have an effect on allergic conditions such as hayfever and eczema, as well as autoimmune conditions (3).

Immune cells in the gut

There are also a lot of other players involved in the gut, such as Immunoglobulin A (sIgA) and certain T lymphocytes.  sIgA helps to protect the epithelial layer from being inhabited by bacteria and viruses.  This helpful immunoglobin is actually produced by lymphocytes (a type of white blood cell) which are actually created by Bifidobacteria (a good bacteria that exists mostly in the colon).  Unfortunately, Bifidobacteria are easily damaged, especially by antibiotics.

Enzymes do more than digest food

When you think about digestive enzymes, you’ll probably be thinking that they’re there to break down your food so it’s primed for absorbing.  They also have another important role to play, and that’s in breaking down substances that might be harmful to your immune system.  Due to poor eating habits, the secretion of enzymes is compromised in a large proportion of people.  Implementing habits such as chewing each mouthful more and taking time to enjoy and concentrate on your meal are helpful for stimulating the cephalic phase of digestion – where your brain tells the rest of the digestive system to get ready for food, and consequently more enzymes and acids are produced.

Fix your gut to improve your immunity

By now you are probably realizing that keeping your gut healthy is pretty dang important. In order to achieve this, there are a few strategies that can be implemented, all depending on how bad your gut and immune system is to begin with.

I highly recommend working with a practitioner in this, particularly if you are looking to assess and treat specific microbial imbalances, as it can be a complicated process that may require stool analysis, and some gut infections can take a long time to resolve so it’s helpful having the support of a practitioner.

Balance your gut flora: This process may need to start with a stool analysis to see if you’re lacking in certain beneficial bacteria, or whether you have a unfriendly bug that needs killing off. Depending on where your gut flora is at, you may need to look at using some herbal anti-microbial herbs or oils to kill off the unfriendly bugs, and also replacing the good guys with a probiotic supplement, as well as probiotic and prebiotic foods.

Repair the gut lining: There are plenty of options when it comes to gut healing. Things like slippery elm, the amino acid glutamine and glycine are my favorite tools for repairing the gut lining. Other options that can be helpful include Aloe Vera and Bone broths.

You also need ample supply of protein in your diet, as well as the mineral zinc.

Avoid irritating foods: This can be different for everyone, but some of the most common irritants for gut health include wheat, dairy and processed soy. As frustrating as it is, food intolerances can be developed to anything, so if you’re unsure what you’re intolerant or sensitive to it may be worthwhile completing an elimination diet or a food intolerance test.

Processed foods, sugar, alcohol and coffee can damage the gut lining as well so if gut healing is your goal it’s worthwhile keeping these foods out of the diet, or at least to a minimum.

Minimise stress: Interestingly the state of our gut and our mental health are interconnected (you can read more about this here) so it makes sense that if you are stressed, anxious or adrenally fatigued it is going to impair your gut healing journey.

Yep, stress affects everything in our body, and this includes stress of all forms. So even if your house isn’t on fire or something similarly dramatic, it doesn’t mean you’re not affected by stress. In this day and age there are a lot of pressures and expectations on people, everyone is usually in a rush and we’ve also got less support networks and rituals in place to help us deal with these stresses. On top of that, most people consume a diet that is less abundant in the nutrients that our bodies need to cope with stress, so it’s no wonder that stress has such as huge impact on our health and wellbeing.

Of course everyone deals with stress differently so the degree to which it affects your health will vary, but I recommend that everyone (regardless of whether you’re trying to heal your gut or not) incorporates stress management techniques into their day. This can include exercise, yoga, meditation, mental stillness, leisure time, time spent with friends or family, or journaling.

When your gut controls your mood: the gut-brain axis

From as early as the 1930’s, scientists were beginning to understand that the health of our digestive system could influence our mood.  The state of our intestinal lining and the balance of bacteria within our digestive system have a major role to play in the production of our neurotransmitters: chemical transmitters that tell our brain whether we should be feeling such ways as happy, sad, agitated, or calm.  But even though the research in this area sky-rocketed in the last decade and continues to grow every day, the concept of our gut-brain connection isn’t very well known.

The gut is linked to the brain

Did you know – When you were just starting to grow in your Mumma’s womb, your brain and your digestive system developed from the same lump of tissue.  During this process of dividing up cells (embryogenesis) this lump of tissue divides and forms our central nervous system and our enteric nervous system (this is the nervous system of our gut – sometimes called the second brain).  These two are connected by an important ‘wire’ – our vagus nerve.  This development can help us understand why there are so many similar chemicals and receptors in both our brain and our digestive system, for instance serotonin.

Gut bugs and your mood

As soon as you’re born, bacterial colonies start to develop in your digestive system.  Within the first few days, the bacteria starts sending messages to the nervous system and can actually determine our nervous system ‘set point’ long term (1).

When the balance of our gut bacteria (collectively referred to as the microbiome) is affected, this can affect your mood.  Studies have found that the microbiome can have a major impact on stress levels and anxiety (2).  In fact, by treating imbalances in our microbiota, it is possible to support a wide range of mental health disorders (3), (4), (5), (6), (7).

The second brain

The nerves in your digestive system are constantly speaking to your central nervous system.  If your gut is irritated for some reason – say you’ve eaten something that you’re intolerant to (like gluten, for example), you’ve generally got a bad diet, there’s an imbalance in your microbiome (that’s your collective gut bacteria, remember) or you’ve got an infection – this can create an inflammatory reaction and will certainly make you irritated as well.  We know that depression is both associated with, and worsened by inflammation.  This inflammation in the brain can be driven by inflammation in the gut, which can be caused by intestinal permeability (leaky gut) and bacterial imbalances (dysbiosis).  Treating leaky gut can help reduce the severity of depression (4), (8), (9), (10), (11).

Neurotransmitters in our gut

Serotonin is produced in large amounts in our digestive system.  In people with Irritable Bowel Syndrome (IBS) there is too much serotonin in their digestive system.  This is why antidepressants known as SSRI (selective serotonin reuptake inhibitors) can improve the symptoms of IBS: these act by reducing the amount of serotonin taken into cells in the rest of our body which allows more to get into the brain.  However anti-depressants can affect the gut negatively as well, because if you weren’t making enough serotonin in the gut in the first place, you’d end up with even lower levels in the digestive tract and so it can become irritated, affectively you’ll get a depressed gut (12), (13).

A vicious cycle

When your gut is upset, you feel upset.  But stress can affect your digestive system just as much as it affects your mood.  It can impair the secretion of digestive acids, slow down the motility of the gut, allows the unfriendly bacteria to grow, reduces your friendly bacteria and exacerbates intestinal permeability (leaky gut) (14), (8).  This is a recipe for an unhappy digestive system, and as you know this can then go on to send more messages to your brain: so you can see how the cycle continues.

People with gut problems are more likely to experience anxiety and depression.  Some studies have found a high proportion of anxiety in those with gut conditions such as Irritable Bowel Syndrome(IBS), Crohn’s disease and coeliac disease (15), (16), (17).

Helping the gut-brain axis.

By treating digestive problems, sealing leaky gut and balancing your microbiome it is possible to help with conditions such as anxiety and depression, and there’s even research showing the benefits of treating the gut in conditions like chronic fatigue syndrome, schizophrenia and autism (10), (18), (11).  Probiotics are one of your major tools when it comes to treating the gut, but it’s a good idea to consult with a health practitioner to make sure you’re getting the right type, and also to get a good gut healing treatment program to go along with it ⁽¹⁹⁾, (4), (9).
