Probiotics are the bacteria found in our intestines used to break down and separate foods in order to get the nutrients to our body. This type of bacteria is beneficial and essential for our bodies. We all naturally obtain probiotics before and after birth. We also get probiotics from yogurt and special supplements. Many people think probiotic supplements are healthy if taken moderately; however, recent studies have shown they can actually be bad for you.

Using a new technology called organ-on-a-chip, researchers at the University of Texas at Austin have found that probiotics can be detrimental to a person’s body if they have inflammation in their intestines (gut inflammation). Organ-on-a-chip is a microchip lined with cell tissue. It is able to perform the same functions as the organ it is modeling but in a controlled environment. In this case, the organ is the intestine. The engineers who made the chip found that probiotics had a harmful effect when the gut barrier was compromised. They found that the probiotics that have a positive effect in the intestine have a negative effect when they reach other parts of the body. This was the first organ-on-a-chip model that showed how a disease develops in an organ. Researchers plan to make other customized organ-on-a-chip models that show the development of other intestinal diseases such as colorectal cancer.
