The Effect of Gut Bacteria on the Human Brain


While research is on the cutting edge, there are several studies that indicate there is a connection between your brain and the microbes living in your gut. Researchers do not understand how it all works yet, but it appears that there is a direct correlation between the health of your digestive tract and your brain’s health. Here are some of the findings that you may want to consider.

1. Improves Emotional Well-being

Scientists believe that thousands of tiny nerve cells located in the enteric nervous system send messages back and forth directly to the brain. There are several brain parts that react to these messages that may cause depression, increase anxiety and make you feel more stressed. Therefore, making sure that there are enough good bacteria in the digestive tract keeps this lining from sending emergency messages to the brain.

2. Helps Improve Memory

Other research studies suggest that there may be a connection between Alzheimer’s and digestive health. Scientists believe that one of the reasons that people develop Alzheimer’s is a buildup of amyloid in the brain. It turns out that the amyloid may leak from the digestive tract and cross over the blood-brain barrier to enter into the brain. Then, it accumulates causing Alzheimer’s.

3. Better Impulse Control


Scientists now believe that there may be a strong connection between allergies and microbes during pregnancy and in the first 24 months in life. Doctors think that microbes cross the placenta helping build their immune system before they are born. If the baby is born naturally, then it gets more microbes while it travels down the birth canal. If the mother chooses to breastfeed, then the baby gets even more microbes in the milk. When the microbes are out of balance, then parts of the brain get overstimulated. The result can be that people can have a harder time controlling their impulse behaviors. As children, this often exhibits itself as temper tantrums while in late life, it can be seen as impulse buying.

4. Prevents Autism

It turns out that there may be a strong correlation between autism and gut health. Doctors have long recognized that people on the autism spectrum are more six to eight times more likely to have problems with their digestive tract than typically developing children. When children on the autism spectrum were treated for their digestive issues, then many times their behavior improved. Doctors are still perplexed if the changes that they are seeing are caused by inappropriate immune activation during birth or by an unusual combination of microbes in the digestive tract. Nonetheless, there seems to be a clear connection worth investigating further.

5. What Can You Do?
