Bacteria are the organisms that people must avoid. But is that true for all bacteria? According to many researches, the Gut Bacteria present in the digestive tract of the human body help in digestion and play an important role in the well-being.
What is Gut Bacteria?
Gut bacteria live inside the gut and is a mixture of 300 to 500 different kinds of bacteria. These bacteria contain approximately 2 million genes. Not only bacteria, but they may also combine with other organisms like Fungi and Viruses to make Microbiome or Microbiota.
Like everyone’s fingerprints are different, Gut mixture of bacteria also differs from person to person.
It depends on many factors like a person’s lifestyle or diet. It also partly depends upon his/her mother’s Microbiota.
How Gut Bacteria is Helpful to Lower the Risk of Diseases -
According to research, people who are sick have less amount or lack of bacteria variety as compared to a healthy person.
Although bacteria live throughout the body, bacteria inside the gut, intestine, or colon may be helpful for well-being and have the biggest impact on digestion. They also play a major role in everything from immune systems to hormonal balance to metabolism.
These friendly bacteria are helpful in the following illness:
1. Provides Immunity
According to a study published by the University of Chicago, bacteria play a vital role in the immune system. In this study, researchers introduced a bacteria strain with melanoma in the digestive tract of mice. These bacteria prompted the immune system of mice to fight against tumor cells. Bacteria in the body help the immune system make natural antibiotics. These natural antibiotics help fight against diseases.
2. Controls Mood
People may often think about how gut bacteria help maintain hormonal balance, but many studies and researches exist that shows the impact of these bacteria on the human mood or mental disorders. The doctors may call this link a "gut-brain axis.” According to Prof Dinan, people who are suffering from depression or any mental disorders have less microbiota than healthy people. Another scientist from McMaster University said that based on the mouse study, gut bacteria may play a major role in depression and anxiety.
3. Manages Appetite and Body Weight
Gut bacteria may also affect the metabolism of the body. They determine the calories the person gets from food, and the kind of nutrients he/she draws from it. High amount of Gut bacteria in the body may change fibers into fatty acids, which lead to the deposition of fats in the liver, and cause “metabolism syndrome.” This can even cause obesity. This shows that by maintaining gut bacteria, one can maintain his/her body weight.
4. Aids Nutrient Absorption
It is important to eat properly, but what if the food is not absorbed in the bloodstream of the body? According to a study at Washington University School of Medicine, gut bacteria play an important role in absorbing nutrients from food. This study indicates that irrespective of one's proper diet, gut bacteria are required to absorb vitamins and nutrients from food. These bacteria help in breaking down the food to provide nutrients to the body.
There are trillions of bacteria that live inside the digestive tract and contribute in many functionalities to the body. One should always eat healthy foods and exercise well to maintain the balance of these gut bacteria.
