Here’s a bigger perspective about bacteria because a lot of people consider them as demons but they’re more like misunderstood angels with an unjustified guilt.

According to the American Psychological Association, our body has one cell per ten unicellular organisms that are mainly bacteria.

That’s one of the reasons why I always say that bacteria are highly important for our health. This concept might go against the common perception but it’s true.

Our gut bacteria have the power to influence our body and also our mind.

When we born we don’t have bacteria initially. Our guts are sterile at birth but that change on labor day because when the baby goes through the birth canal it is covered with the mother’s bacteria. Babies also get bacteria through the breastmilk and through the environment. In this way, babies start to develop their own bacteria based on inherited bacteria from the mother.

By the way, microbiota is the collection of all the microorganisms that live in our gut.

Throughout our life —depending on our experiences and our environment— our microbiota will change. One of the most important factors that define a healthy microbiota are the foods we eat.

More than 100 trillions of microbes live in our guts and influence our health. Wow, I know. That number is huge. Nevertheless, there are still some people that are scared of some microbes in their environment.

I want to remove the absurd concept where bacteria are demons. Is not like that. That mindset is for people who want to be sick which doesn’t apply to us.

All these trillion microbes can influence our health in a very positive way.

The gut bacteria can improve digestion and metabolism. It can extract and produce nutrients like vitamins using the food we consume. It can strengthen the immune system. It protects the walls from our guts to avoid permeability.

The gut bacteria produce 95% of the serotonin in our body which influences our mood and gut activity.

If you wonder how gut bacteria can do this, the truth is yet unknown but there are some hypothesis about the process. One of them is that gut bacteria use immune cells and also synthesize neurotransmitters that send signals to our brain.

When there’s a gut infection, our intestines produce molecules called inflammatory cytokines that alter the brain’s neuronal chemistry which produces vulnerability to anxiety and depression. So there’s definitely a connection between our gut and our brain that cannot be denied.

I consider that the key to this understanding relays on the bacteria, in other words, on our microbiota.

 

I’m sure we’ll be learning more and more as the time goes so as soon I discover some new advances on this topic I will explain it here. Therefore you should subscribe to the [newsletter] so you don’t miss any of that.

If you want to share this post with other people that’s probably because your microbiota is telling you so since it must be the most healthy thing to do for you and others, so do it. I’m kidding, although share this post anyway since it’s free.
