Long time readers know that I am a huge fan of taking a probiotic supplement daily or including some raw sauerkraut in the diet daily as a source of the good bacteria. As a reminder, our bodies contain billions of good bacteria collectively called our microbiome. Most is contained in the gut – where we have 3-4 POUNDS of bacteria living there. Cell for cell, our microbiome outnumbers our body cells by a rate of 9:1. This means that 90% of our body is made up of bacteria and the other 10% is our own body cells, your skin, liver, brain, heart, muscles, etc. Science is still only scratching the surface of knowledge on our microbiome and how important it is to our health and wellbeing.
An important bacterial strain in our bodies is the Lactobacillus strain. There are a couple hundred individual strains within Lactobacillus. An analogy would be that Lactobacillus is like the category of Fruit. Fruit is a category and contains these specific types of fruits – cherries, apples, pineapple, mango, etc. There are way more Lactobacilli types than fruit! The most common one you have heard of is Lactobacillus acidophilus.
How does taking a probiotic supplement or eating probiotic rich foods work? It’s not a simple strategy of take this probiotic pill and it will repopulate your gut and keep you healthier. If only that worked, we’d only need to take one pill of a probiotic and voila, you are repopulated. Oh no…..
What happens when we take the probiotic? A small percent of that pill (or the sauerkraut) will populate the gut, but most of the beneficial effects of the probiotic is what the bacteria are doing in our gut for us as they pass through until we p**p them out. That’s why we have to take the probiotic every day.
How can you make your gut more inhabitable by these good bacteria? It needs to be healthy in the first place. Eating lots of fiber rich foods (fiber is what feeds the good bacteria). Avoidance of alcohol, sugar, smoking and stress are prime helpers here. These all cause damage to the gut and make it harder for the gut to be populated.
The take home message here is twofold:
1. Keep your gut healthy through the proper diet to allow for the colonization of the good bacteria.
2. Take the probiotic everyday or eat raw sauerkraut every day to assure that there are some good guys going in for at least part of the time before they are p**ped out.
