Summary
- Gut bacteria play an important role One important reason plant based foods may be beneficial is their effect on the gut microbiome the large community of bacteria living in the digestive system.
- Gut bacteria break down fiber and turn it into different compounds that can affect the body in various ways.
- The first study found that plant based fiber and certain plant proteins can change how gut bacteria process nutrients. These changes may increase some helpful metabolic compounds while reducing certain potentially harmful ones.
Eating more plant based foods may benefit several areas of health including digestion the immune system metabolism and heart health.
New research is helping scientists understand how foods from plants interact with the bacteria in our gut and influence the way our body processes nutrients.
Gut bacteria play an important role
One important reason plant based foods may be beneficial is their effect on the gut microbiome the large community of bacteria living in the digestive system.
Dietary fiber is especially important. Gut bacteria break down fiber and turn it into different compounds that can affect the body in various ways.
Plant chemicals may also help
Plants contain natural chemicals called phytochemicals. These compounds help plants protect themselves from environmental stress. When people eat plant foods these chemicals may also have different effects inside the body.
What did the new studies find?
Two studies led by researchers associated with Princeton University provided new information about the connection between diet, gut bacteria and metabolism. One study was published in Proceedings of the National Academy of Sciences while the other appeared in Nature Metabolism.
The first study found that plant based fiber and certain plant proteins can change how gut bacteria process nutrients. These changes may increase some helpful metabolic compounds while reducing certain potentially harmful ones.
The second study found that some metabolic compounds previously thought to be produced mainly by gut bacteria can also be made in significant amounts by mammals themselves.
Why this research matters
Researchers are increasingly interested in using the gut microbiome and the compounds it produces to improve health. However scientists first need to understand exactly how different parts of our diet affect specific gut bacteria and the substances they produce.
Future health benefits
These findings could eventually help researchers develop better dietary strategies and treatments aimed at supporting a healthy gut microbiome.
In the future this may make it possible to use food choices more effectively to encourage the production of beneficial compounds in the body.
