A July 2022 study by Duke University said,

  • “The people who responded the best had been eating the least fiber to start with,” 

  • “We’ve evolved to depend on nutrients that our microbiomes produce for us,” 

  • “But with recent shifts in diet away from fiber-rich foods, we’ve stopped feeding our microbes what they need.”

  • “We didn’t see a lot of difference between the fiber supplements we tested. Rather, they looked interchangeable,”

  • “Regardless of which of the test supplements you pick, it seems your microbiome will thank you with more butyrate,” 

  • “If you’re a low fiber consumer, it’s probably not worth it to stress so much about which kind of fiber to add. It’s just important that you find something that works for you in a sustainable way.”

  • “It doesn’t need to be a supplement either,” 

  • “It can just be a fiber-rich food. Folks who were already eating a lot of fiber, which comes from plants like beans, leafy greens, and citrus, already had very healthy microbiomes.”
