Intestinal Bacteria and Their Importance

By Richard Bell

Intestinal Bacteria, also known as Gut Flora are organisms that live in our intestines and keep us healthy by performing several important functions. The average human has about thirty trillion microorganisms in their stomach, with about five hundred different species. They perform as much work as any of our major organs, but are never mentioned as something we need in order to stay healthy.

Our faeces are about sixty percent bacteria, which is why doctors ask for a sample when we have an intestinal illness. This is the most non-invasive manner in which tests can be run to help determine what is upsetting the stomach.

When babies are born they have no bacteria in their system, however their body quickly picks up bacteria from the mom and surrounding environment, and within a few months their body is able to build up the healthy bacteria. Babies born by caesarean deliveries are seen to take longer to build up these bacteria as compared to babies born normally.

The bacteria in our stomach perform various different roles such as fermenting, maintaining a healthy resistance level, fighting the harmful bacteria, creating vitamins, and helping us store fat. Firstly they break down carbohydrates; as a result our body can absorb the nutrients from it. With no bacteria in our intestines, we would not have been able to break down a lot of food that we eat, and therefore would need to eat more to remain healthy.

These bacteria also stop the dangerous bacteria to grow in our digestive tract. Due to the struggle in the tract between different types of bacteria for room, the bad bacteria are unable to grow up because the helpful bacteria do not allow them to have any space. Humans with no any intestinal bacteria could to get sick more often when compared to those with normal levels.

These bacteria are also helpful in building up our immune system so we dont fall sick. Due to a tolerance for healthy bacteria that we develop in our childhood, the immune system is proficient to battle the bad bacteria, therefore leaving behind only the good bacteria. These bacteria are also helpful in preventing from all sorts of allergies and inflammatory bowel disease.

However, today the use of antibiotics and other medicines is increasingly upsetting our digestive system, since the medicines do not differentiate between the different types of bacteria in our body and wipe out the bad bacteria and the good. This leads to diarrhoea and other illnesses of the bowel. While we may not be consuming antibiotics deliberately, a lot of the dairy and meat we consume now contains antibiotics, which are given to the animals to prevent illnesses. The use of Probiotics is now popular to help the good bacteria thrive in the gut, since probiotics aid the bacteria in their functions by helping fight harmful bacteria and boosting the immune system.

It is vital to be aware of the fact that not all bacteria are bad for us, and that our body has many millions of bacteria in it that are actually helping it stay healthy. - 16004
