Would you believe me if I told you that you are made up of trillions of bacteria? Sounds crazy right?
At any given time, we have more bacteria (in and on us) than we have human cells. How is that for a “did you know?”
Bacteria is found everywhere throughout your body. One very important place it is found however, is in your gut.
The gut’s lining, is covered with microscopic bacteria and organisms which impact your health. Your lifestyle, mood, activity, diet all impact the balance of these microorganisms. It’s this microecosystem that is referred to as your gut microbiome.
What you want, is good bacteria to make up your microbiome.
Good bacteria contribute to our overall health and well-being. We are continuously discovering the never-ending extent into which these little bacteria are beneficial to us.
Certain strains of bacteria do really beneficial things in our body such as:
You will find different families of bacteria in different areas in the gut. In the colon you will mainly find anaerobic bacteria you commonly hear such as for Peptostreptococcus, Bifidobacterium, Lactobacillus, and Clostridium. These “good bacteria” also work to prevent the growth of the “bad bacteria”.
There are many ways to keep your gut microflora strong and thriving, in order to help contribute to better health. Listed below are a few ideas of how to incorporate these into your daily routine.
Your gut houses up to 1,000 different species of bacteria?
I know you hear this often, but we all need reminders from time to time. The bacteria in your gut love the fibres in fruits and vegetables. They use the fibre as a source of energy and it helps them grow strong, which in turn helps keep us strong.
Here are some tips to follow:

I know this is easier said than done, but it is incredibly important. Stress wreaks havoc on your intestinal tract.
Constantly being in a state of stress will cause long term damage all over your body, but especially in your gut. This is important because the bacteria in your gut need a healthy environment to thrive.
So how do you mitigate the sometimes-unavoidable effects of stress? When you find yourself overwhelmed by daily stressors in life:
Using antibacterial products consistently will also damage your microbiome. This means it will destroy the bad bacteria and the good bacteria that keep us healthy.
It is also especially important that our immune system does get exposed to bad bacteria. This exposure is vital for our body's ability to build up immunity to these not-so-friendly microbes. It allows our immune system to defend itself more readily in future exposures to these strains. Our bodies are brilliant and will constantly build immunity to bad bacteria and protect us more often than we realize. It is important to have this immunity strong for times when we really need it. When we use antibacterial products often, we kill off beneficial bacteria, and do not provide our immune system with enough exposure to bad bacteria. Without this exposure to bad bacteria, our immune system cannot build up the correct resistance - sometimes it is okay to get a little dirty!
If you want to maintain a healthy microflora the true trick is to keep it simple! Eat a variety of fruits and vegetables in your diet, work on reducing stress. Next time you are at the park with your children, try playing with them in the sandbox!
Note: Kids should be taking probiotics daily, get their microbiome off to a healthy head start.
