A high-fiber diet rich in vitamin A may alter gut bacteria in a way that could prevent or reverse food allergies. In their study, the team found that increased levels of these fatty acids work with the body's immune system, preventing dendritic cells - which regulate food allergies - from triggering an allergic response. Vitamin A is also important for dendritic cell regulation.

Key Takeaways:

  • When mice were raised germ-free, then given a transplant of human gut microbes, the impact of fiber on their colons could be seen.
  • In a new paper in Cell, an international team of researchers show the impact of fiber deprivation on the guts of specially raised mice.
  • The findings have implications for understanding not only the role of fiber in a normal diet, but also the potential of using fiber to counter the effects of digestive tract disorders.
