What is gut health?

The medical literature and the food & nutrition industry have dawned with the realization of the critical organ Gastrointestinal Tract (GI tract) and its health benefits.

Popularly known as the ‘Gut Health’ in this modern era, the gut microbiota plays an important role in the health and well-being of the person.

The food travels from the mouth to the stomach, it absorbs the nutrients in the body, stores energy and excretes the substances from the body in a timely manner.

The gut microbiota holds multiple health benefits in the aspects of the gastrointestinal tract (GI tract). The GI tract aids in effective digestion, absorption and excretion of the food from the body, improved gut health and decreased illness.

Good gut health maintains the immune system and well-being of a person. Taking good care of the body is essential in today’s world. The one who nourishes his body wins life! Let us look at why maintaining gut health is important.

Importance of gut health

In recent years, many researchers and scientists have looked at the bigger picture of the GI system that is even bigger and complex than its previously known importance.

The GI tract is full of trillions of  gut bacteria that not only help us process food but that also help our bodies maintain homeostasis (state of steady internal, physical, and chemical conditions maintained by living systems) and overall well-being.

The experts have mentioned that the key may lie in the microbiome (the makeup of bacteria) and other microorganisms in the stomach and intestines.

There are few generalities when it comes to healthy gut microbiota. Every individual has a unique microbiome developed in his or her gut.

Healthy gut involves a various array of microorganisms in the gut like most bacteria, some include fungi, viruses and other microbes as well.

Animal experiments and some human data have shown that the gut communicates with bacteria that support digestion by their enzymatic capacity.

Impact of gut health on your body

The GI microbiome prevents colonization by pathogenic microorganisms, provides energy for the gut wall from undigested food. The GI system also regulates the immune system, serving as an important source of immune stimulators.

Some of the bacteria fight inflammation while some promote it. When your gut is healthy, it can lead to good mental well-being defeating the anxiety, stress and depression and to neurological conditions like schizophrenia and dementia.
