Why Your Body Needs Good Bacteria

The body contains trillions of bacteria at any given moment. Not all these bacteria are 
harmful. In fact, good bacteria are important aids for the body. Here are some reasons 
why your body needs good bacteria, just as much as you need to reduce the bad 
bacteria. 

 
The Gut and Immune System 
 
Most people know the immune system is a vital part of overall health. Did you know that 
your gastrointestinal tract affects a large part of the immune system? There are 
hundreds of bacteria that are living in the gastrointestinal (GI) tract, but it is important to 
have higher levels of good bacteria. 

 
Benefits of Good Bacteria 
 
There are a wide variety of benefits that come with a normal level of good bacteria. 
Healthy digestion relies on good bacteria. The bacteria help break down foods, 
particularly carbohydrates. They also aid in fatty acid absorption. 
 
Good bacteria help prevent a pathogen invasion and aid cells in repairing damaged 
tissues. Your immune system benefits from a boost provided by good bacteria. Most 
notably, an ideal level of good bacteria will work to keep bad bacteria levels in check, 
naturally fighting of illnesses and diseases. 
 
In addition to all its other benefits, a healthy level of good bacteria can help fight heart 
issues. Blood sugar, inflammation, and cholesterol can all be impacted by good 
bacteria. Dietary choices and probiotic supplements are often recommended in 
maintaining a healthy heart. 

 
Maintaining a Healthy Balance 
 
One way to keep your good bacteria levels higher is through dietary choices. Foods 
such as fruits, beans, and yogurt contain natural good bacteria. Whole grain foods are 
rich in fiber. When broken down by good bacteria, such things as weight and risk of 
disease are affected. 
 
Try not to rely on antibiotic medications unless it necessary. Antibiotics target and 
destroy bacteria that cause illness and infection. Unfortunately, antibiotics cannot 
distinguish between good and bad bacteria. Good bacteria get destroyed as well. If you 
need antibiotics, try to increase your intake of good bacteria following treatment to help 
bring levels back up and help the immune system recover. 
 
Limit use of disinfectants. Most people today rely too heavily on hand sanitizers and 
washing their hands too frequently. Although it might be the logical way to avoid illness, 
it can harm your immune system’s ability to naturally fight off illness. Without exposure 
to germs and other pathogens, the immune system cannot make its own antibodies. 
When you do get sick, because not all germ-killing aids kill all germs, your immune 
system struggles and has to work harder to fight the illness.
