Scientists say that humans may have a second brain, you know, Yes, a second brain. Maybe you don’t think that our digestive system is not only in charge of digesting food and absorbing nutrients. Moreover, our digestive system acts as a communication center with the brain and is at the forefront of disease prevention. No wonder the digestive system of food is called the second brain.
Second Brain Special
The digestive system of food has its nervous system, called the Enteric Nervous System (ENS). That is our second brain because the SSE can regulate the function of the digestive system independently without relying on the central nervous system (brain), as well as communicate in two directions with the brain2. If we liken it, our nervous system is like a state, with the brain as the central government, and the ENS as a unique autonomous region.
The second brain is so unique because, in addition to regulating digestive functions, it also regulates immune and hormonal purposes. The ENS responds to any changes that occur in our digestive tract. Signals from the digestive tract are then converted into nerve impulses that are transmitted to the intestines and other organs, including the brain.
This connection between digestion and the brain is known as the gut-brain axis. The digestive tract will affect the brain to produce hormones, one of which is serotonin, which produces feelings of pleasure and comfort. So whatever intake is consumed by the child not only strengthens the digestive tract but also the brain and the greatness of his heart.
Interestingly, the condition of the gastrointestinal tract, especially the intestines, plays a majority role in the growth and development of children. A study of stunted children aged 2-5 years in sub-Saharan Africa found that stunting was most likely related to an imbalance of bacteria in the small intestine.
