Why is the gut considered our “second brain”?

Our Intestines It has more neurons than our spine and operates independently of our central nervous system. For this reason, the researchers from area health You suspect that the functions of the digestive system may be much more than just digestion foods.

In order to understand why so many people think of the gut, we’ve broken down some information that can help you make sense of this analogy:

1. Immune factor

Roughly 70% of all cells of our immune system inhabits the intestines. Therefore, taking care of the health of this organ can be the key to a healthier life.

2. “Thinking” alone

This is the only member who can get it Autonomy in decisions, does not require commands from the brain. Everything in the digestive system is regulated by the enteric nervous system (ENS), which, although independent, communicates with the central nervous system (CNS) through the sympathetic and parasympathetic systems.

3. Direct connection with the mood

About 80 to 90% of all serotonin in the human body is found in Digestive. And no wonder, because this substance is responsible for the peristaltic movements that ensure that digestion takes place in the right place.

However, this will not be the only function of the neurotransmitter, it is involved in regulating levels of stress, anxiety and happiness.

Following this line of reasoning, some recent studies have shown the link between different states of the gut microbiome and mental disorders such as depression.

4. Microbial diversity

Such as Microbiome health From the gut seemingly related to mental health, it is possible that a varied diet cooperates with both. This is because different types of gut microbes need different foods to stay alive and healthy.

After all, it is really possible to believe that phrase “You are what you eat.” Impressive, isn’t it?!
